It is also a very modern instrument, as proved by some recent events. The ambition of this paper is first to outline some models of central banks communication on ELA; second to redress some common places about what Bagehot would have written on this topic in his Lombard Street; th.rd to review the decisions enacted by policy makers in the banking crises of Sweden (early 1990s), United Kingdom (1995), United States (2001) Austria (2006) and again United Kingdom and United States ( ). Overall, the main message we can gather is that if crisis management is about (re)building trust in financial markets, neither in its words nor in its deeds the central bank should be perceived as hesitant. (J.E.L.: E42, E58, G21, N31, N33) almost two hundred years after Thornton, the lender-of-last resort function remains an art not a science, to be applied on a case-by-case basis. Giannini (1999) I. Introduction Emergency Liquidity Assistance (ELA) to financial firms in distress is a central banks function as old as these institutions can be, to judge from the fact that its classic and ever-green foundations were laid down by Thornton in 1802 and Bagehot in his 1873 Lombard Street book. Such an honourable history does not call the case closed on ELA and, in the midst of the market turbulence originated in 2007 in the US subprime credit segment, prominent central bank Governors felt appropriate to restate their views on emergency refinancing and on the lesson by Bagehot 1. Arguably, issues such as the role of the instrument in crisis management or the balance between transparency in its communication and grip on moral hazard remain part of the debate on *Paper accepted in september ** Bank of Italy. My thanks are due to C.O. Gelsomino, who was the source for much food-for-thought on the topic of ELA, R. De Bonis, P. Maggio, C. Mastropasqua, S. Nobili, F. Panetta and the participants to an internal Bank of Italy seminar for helpful comments. I am also indebted to R. Potito for a number of editorial suggestions. The views expressed here are the sole responsibility of the author and do not necessarily reflect those of Bank of Italy. 1 Consider e.g. the speeches given by B. Bernanke, Chairman of the US Fed, on 13 May 2008 and G. Stevens, Governor of the Reserve Bank of Australia, on 15 April 2008.
2 156 Studi e Note di Economia, Anno XIV, n central banking. The ambition of this paper is to journey through the topic of ELA by dealing with both theoretical and practical issues. To do so, the paper will revolve around four questions: 1. What is ELA? 2. How central banks communicate on ELA? 3. Which conditions may be applied on the emergency assistance? 4. How do central banks actually intervene in financial crises? The first question could seem a trivial one basic intuition identifies ELA as central bank credit granted in emergency situations, as suggested by the acronym if it were not the case that doubts linger on whether ELA is anything different from ordinary monetary policy operations. On a different ground, the emergency condition may be a necessary though not a sufficient one if, say, the Fed s loosening of its liquidity supply on the aftermath of September 11 th is usually reckoned more a form of lending to the market than, strictly speaking, ELA. If ELA is part of the armoury of a central bank, as most analysts would agree, this institution cannot escape the problem of how best to craft its communication on the instrument. A survey over the Statutes, Acts and other official documents of 18 central bank helps to identify some basic models of communication, ranging from near silence to formal open statements. The answer to the second question is complemented by an analysis of a number of recent memoranda of understanding on crisis management. Because these documents are less constrained by legalistic language, they offer good examples of how central banks communicate their intended strategies on crisis management and thus on the extraordinary refinancing. Dealing with the third question almost unavoidably implies touching base on the triplet associated to the name of Bagehot, namely that at times of crisis the central bank ought to lend (i) at a high rate of interest, (ii) on good banking securities and (iii) freely. In fact, a reading of the original work by this author suggests more nuances than this would-be dictum suggests. Goodhart (1999) is a sure reference on how to dissect the accretion of myths from shallow readings of Lombard Street. So much about the words on ELA. The fourth question looks at the related deeds. Here, I follow a business case approach by reviewing the actions taken within the management of some recent financial crises. The focus will be on the crises of Sweden in the early 1990s, United Kingdom in 1995 (Barings), United States in 2001 (after September 11 th ), Austria in 2006 and again United Kingdom and United States in (Northern Rock and Bear Stearns). By way of introduction, I should also define the boundaries of the present work and clarify a terminological element. With a view to striking a middle point between breadth and depth of the research, the list of questions I proposed above is not exhaustive and, say, other relevant topics include the international domain of the lender of last resort (Giannini, 1999, and Jeanne and
3 M. Manna - Emergency Liquidity Assistance at work: both words and deeds matter 157 Wyplosz, 2001) and the stress testing activity (Sorge, 2004). Furthermore, this is not one more survey on ELA. Not because writing a survey is less relevant, but because excellent ones are already available (Freixas et al., 2000, is among my favourites). I should also state my preference for using in this paper the term emergency liquidity assistance (ELA) vs. lender of last resort (LOLR). The two terms are often used interchangeably, although they may carry different nuances as the latter is perceived as broader in scope. Let us give here the floor to two central banks, Bank of Canada and Sveriges Riksbank, whose official publications featured an article on the lender of last resort, as made it clear in the title 2. In both cases, the article covers a number of issues relating to the role of the central bank in financial crisis management; however, within each of the two articles, the section referring to the provision of emergency credit by the central bank turns to the term emergency liquidity assistance. Accordingly, I will mainly speak of ELA since the paper chiefly deals with the act of providing liquidity under emergency. This notwithstanding, in citing the literature I will feel free to switch to LOLR if this is the term used by the author and by which her/his work is more often remembered, to avoid distracting the reader with non-substantive elements of notational content. The rest of the paper is organised as follows. Second II to V try to answer to each of the questions outlined above, while in section VI some concluding remarks are put forward. II. What is ELA A basic issue a paper like this should try to address relates to what is ELA in the first place. In terms of the mechanics of the operation, ELA is about granting credit to a financial counterpart, typically a bank, under exceptional circumstances and usually against collateral. Most of these qualifications could equally apply to an ordinary central bank open market operation. For sure, the nature of the counterpart and the request for collateral are not peculiar. I will also argue below that the level of the applied rate of interest is not necessarily a discriminating element in recognising an ELA. Thus, one should not be surprised if some authors do not recognize the emergency lending as a separate central bank tool, since any liquidity provision to the market falls, in their judgement, within the broad spectrum of open market operations. Arguably, a noticeable feature of ELA relates to the extraordinary circumstances prevailing when the refinancing takes place, circumstances which apply to the financial firm receiving the assistance (and not necessarily to the market as a whole). 2 Bank of Canada (2004): Bank of Canada Lender-of-Last-Resort Policies ; Sveriges Riksbank (2003): The Riksbank s role as lender of last resort.
4 158 Studi e Note di Economia, Anno XIV, n This firm may be troubled by an IT or other technically-related failure which prevents its ordinary trading in the interbank market. The accident occurred at the Bank of New York in 1985 (a computer failure) proves that this is not academic theory; this being acknowledged, the instance of an ELA in response to a liquidity crisis triggered by an outage is a bit of a rarity. More common seems to be a scenario where some (non-technical) shock leads to heightened uncertainty and more risk averse attitudes. If information about the value of banks assets were freely available, market participants would be able to fully conduct peer monitoring and there should be nothing like an illiquid but solvent bank, because the latter condition (solvency) would ensure the access to the interbank credit and thus remove the former (illiquidity). In fact, information is often incomplete and costly and this is likely to be even more so during financial crises. To play safe, market participants curtail their credit lines, without much discriminating between counterparts actually affected by the shock and those that have no direct link with the firm setting off the crisis. Under these circumstances, even if liquidity supply is adequate at an aggregate level, some banks could no longer manage to borrow enough funds even though in principle they would be creditworthy. As a result, their reserve account with the central bank heads toward negative territory, unless they receive an additional cash injection. Hence, in an ELA operation, we observe an ad hoc cash injection which is targeted by the central bank specifically towards the bank(s) in need, so that a more general increase in the aggregated liquidity supply would not necessarily be the right cure to subdue the crisis (although it may help) 3. From this, one could gauge that the so-called lending to the market, i.e. when the central bank opts for keeping liquidity supply unusually ample in response to some major event, is not ELA. This is exactly because the central bank goal is to increase the overall supply, and not to modify its distribution at a micro level 4. As in many areas of the debate on public intervention, views are split over whether the authority is better placed than market participants to selectively aid illiquid banks. In a well-known paper, Goodfriend and King (1988) conclude that there is little evidence that public lending to particular institutions is either necessary or appropriate, a view upheld also in Kaufman (1996). Their basic argument is that the central bank should be content with regulating the aggregate liquidity supply, leaving to banks the subsequent distribution of funds as a way to enhance peer monitoring. On a different line of thinking, supporters of free banking theories dispute the need for a central bank and thus, a fortiori, for discretionary forms of interventions. The expe- 3 A formal model that caters for illiquid but solvent banks is in Rochet and Vives (2004), a model of the lender of last resort in the context of a payment system crisis is in Flannery (1996). 4 This paper will cover however also the Fed response to September 11th, as an example of liquidity management in a crisis situation,
5 M. Manna - Emergency Liquidity Assistance at work: both words and deeds matter 159 riences of free banking in Scotland from 1792 to 1844 and Canada throughout the nineteenth century are generally rated as rather positive, although the extent to which these were fully free banking systems remains up to debate; a short summary of these two experiences is presented in annex. However, on the whole, the consensus is skeptical on the possibility that a banking systems may prove to be financially stable over a lengthy period without some authority ready to provide ad hoc external funding when circumstances warrant. That is, some public authority must provide the lender of last resort (Bordo, 1989). The consensus view builds on two basic arguments. First, it is as a fact of life that embattled banks do receive some type of support more often than not. In a survey over 104 banking crises occurred mostly in the 1980s and 1990s over 24 developed countries, Goodhart and Shoenmaker (1995) count 81 instances were some form of external funding was made available to failing banks and only 23 instances of no funding 5. Second, on a more theoretical level, the argument à la Goodfriend and King requires perfect repo and unsecured interbank markets (Freixas et al., 2004). In fact, in the aftermath of a shock the information advantage enjoyed by the monetary authority visà-vis ordinary participants is reckoned, if anything, to be widening. Furthermore, while the former weighs the cost of the selective lending (think to the moral hazard) against the benefit of reducing the likelihood of a systemic crisis, the latter is concerned with the financial risk-return profile of the deal at stake. As a result, even if the central bank and the single market participant availed of the same (limited) information set, the ensuing decision taken by these two pehes may turn out be different. III. When the central bank utters the E L A words Communication in this field could be a misnomer if a lender of last resort should exist, but his presence should be doubted (Kindleberger, 1978). As implicitly suggested by this quote, one option for central banks in designing their communication on ELA is not mentioning the issue altogether. By saying as little as possible on the conditions to receive the emergency lending, the illiquid bank will naturally tend to consider first better-known sources to tap its demand for funds and, hopefully, it will eventually turn to the central bank for ELA only when no alternative is in sight. Alternatively, the central bank can explicitly state its readiness to provide ELA when appropriate, although usually a number of caveats are embedded in the statement. 5 It is fair to acknowledge though that, from the viewpoint of an advocate of free banking, the banking system would find in itself the remedies to the crisis, with no need for external support, if there were no central bank in the first place. A survey of the so-called fiscal costs of a number of financial crises is in Dziobek and Pazarbasiogolu (1997).
6 160 Studi e Note di Economia, Anno XIV, n Before proceeding further, it is honest to acknowledge that the gulf between the alternative policy options of near-silence and open disclosure could be narrower than it looks at first sight. As will be argued below, the preference for setting out public guidelines on emergency refinancing probably owes more to earlier interventions on the occasion of a crisis, which make less meaningful the point of being (almost) silent, rather than to theoretical differences on the best communication policy (Sveriges Riksbank, 2003). References to ELA in the law, the Statute and other official documents of central banks A survey of publicly available documents issued by 18 central banks returns three benchmark models of communication on ELA: - in six central banks (Austria, France, Greece, Italy 6, Luxembourg and Germany), few or no explicit references about ELA can be in found in their Statute or other legislative texts, nor many utterances have been made by the Governor and other members of the Board 7 ; - in four central banks (Belgium 8, Finland 9, Ireland 10 and Switzerland 11 ), the Statute includes a reference to the duties of the central bank towards preserving financial stability, while a more explicit acknowledgement of its potential recourse to ELA can be found in other documents published by the central bank; in the case of the Netherlands the latter statement only applies 12 ; 6 In its Financial Sector Assessment Program on Italy of 2006, the IMF staff states: Although financial institutions may request emergency liquidity assistance (ELA) from the BI [Bank of Italy], they have not availed themselves of this option since the establishment of a new institutional framework in 1999, pursuant to the establishment of the ESCB (page 15; the document is available at 7 The validity of this statement is confined to the speeches to which I had access browsing the central banks websites. 8 Statutes of the National Bank of Belgium, art. 23 (1): The Bank shall contribute to the stability of the financial systems. In its website, this central bank adds: The National Bank holds a key position as the lender of last resort. 9 Act on Bank of Finland, art. 3: The Bank of Finland shall also.. participate on maintaining the reliability and efficiency of the payment system and overall financial system. In its website, the Bank Finland states: The Bank of Finland aims at maintaining confidence in the financial system without having to intervene. The Bank may, however, assume a more active role if the smooth functioning of the financial system is threatened. The last example of the Bank s intervention was in the early 1900s, during Finland s business crisis. 10 Central Bank and Financial Services Authority of Ireland Act 2003, art. 5(b): the objective of the Bank in contributing to the stability of the State s financial system. In its website this central bank clarifies: The Bank s responsibility to contribute to the overall stability of the financial system also involves:.. iv. Undertaking official financial operations in exceptional circumstances. 11 Swiss National Bank Act, art. 5 (2)(e): [the National Bank] shall contribute to the stability of the financial system. Swiss National Bank (2006) clarifies further that the SNB also acts as lender of last resort. In this function, it can provide emergency liquidity assistance for one or more domestic banks. 12 The Bank Act 1998 of De Nederlandsche Bank does not include explicit references to ELA / lending of last resort. In a speech given in 1992, Governor Wellink elaborating on Central Banks as guardians of financial stability emphasised that Central banks have always been involved in trying to preserve financial stability, for instance through their role as lender of last resort.
7 M. Manna - Emergency Liquidity Assistance at work: both words and deeds matter in further six central banks (Japan 13, Norway 14, Portugal 15, United Kingdom 16, Sweden 17 and the United States 18 ), explicit references to the ELA / LOLR can be found in the Statute and other official documents. In between the first and the second group of central banks, one could classify the Banco de España whose Statute explicitly foresees duties in the field of financial stability, but it does not further detail whether this could actually imply the offer of ELA, nor this can easily be inferred from other official documents relating to this central bank 19. If an open stance on the subject is a viable option, as the survey suggests it is more common than often acknowledged, it should be of some interest to look more closely at the precautions taken to control for the risk of moral hazard. Let us follow here two central banks that have been particularly transparent on the subject. Bank of Canada (2004) sets out a clear guideline: the Bank provides ELA only to institutions judged to be solvent. It also acknowledges however that there may be contingencies which, though unlikely, cannot be dismissed altogether and call for a different line of action: In the extremely unlikely event of the failure of more than one LVTS [Large Value Transfer System] participant on the same day... the Bank could be obliged to lend to a failed institution, on a partially unsecured basis, to ensure settlement of the LVTS and so protect against systemic risk. One could thus understand that, if the worse comes to the worst, the central bank would no longer necessari- 13 The Bank of Japan Law, art. 37.1: The Bank of Japan.. may provide uncollateralized loans to financial institutions.. and other financial business entities prescribed by a cabinet Order.. when they unexpectedly experience a temporary shortage of funds for payment due to accidental causes. The following art. 38.1: The Prime Minister and the Minister of Finance may request that the Bank of Japan to conduct the business necessary to maintain an orderly financial system, including provision of loans, when it is believed to be especially necessary for the maintenance of an orderly financial system. 14 Act of Bank of Norway, art. 19 (3): when warranted by special circumstances, the Bank may grant credit on special terms. 15 Banco de Portugal, Organic Law, art. 12: it shall be particularly incumbent upon the Bank to:.. c) Provide for the stability of the national financial system, performing, for the purpose, in particular, the function of lender of last resort. 16 Memorandum of Understanding between HM Treasury, the Bank of England and the Financial Services Authority, art. 14: In exceptional circumstances, there may be a need for an operation which goes beyond the Bank s published framework for operations in the money market. Such a support operation is expected to happen very rarely and would normally only be undertaken in the case of a genuine threat to the stability of the financial system to avoid a serious disturbance in the UK economy Sveriges Riksbank Act, Chapter 6, art. 8: In exceptional circumstances, the Riksbank may, with the aim of supporting liquidity, grant credits or provide guarantees on special terms to banking institutions and Swedish companies subject to the supervision of the Financial Supervisory Authority. 18 Federal Reserve Act, Section 10A Emergency Advances to Groups of Member Banks, art. 1 ( Authority of Reserve Banks to Make Advances ): any Federal reserve bank may make advances.. to groups of five or more member banks within its district.. provided the bank or banks which receive the proceeds of such advances as herein provided have no adequate amounts of eligible and acceptable assets available to enable such bank or banks to obtain sufficient credit accommodations from the Federal reserve through rediscounts or advances other than as provided in section 10b. 19 Again, this statement is applicable only to the documents I browsed, i.e. in effect those available on the website of the Banco de España.
8 162 Studi e Note di Economia, Anno XIV, n ly abide by the principle of illiquid but insolvent and its practical equivalent of full guarantee. As to the potential recipient of the credit, these are ordinarily (if this is the right word in the context of a financial crisis) identified in the banks; however, Under extreme conditions, the Bank can provide liquidity to any firm. A somewhat similar path is followed in Sveriges Riksbank (2003): To avoid the unnecessary retention of inefficient banks and distorting bank behaviour, the Riksbank should not support banks that lack long-term survival capacity 20 (emphasis in the original text). At the same time, it is almost unavoidable that the tendency to refrain from granting liquidity assistance declines where systemic risk is substantial, even if the assessment of the institution s ability to pay is uncertain. As to the recipients, while It is primarily if a bank suffers liquidity problems that the Riksbank has reason to intervene, it is also the case that other companies than banks can give rise to contagion risks in the financial system, thus suggesting that the extraordinary support could be extended to other financial firms. The age of memoranda A remarkable feature of the nouvelle vague on the communication on crisis management is the signature of a Memorandum of Understanding (MoU) by the authorities entrusted with maintaining financial stability. All the consulted MoUs seem to lack the binding power of a law or even of a contract; they define however a commitment and as such they may be regarded as a piece of soft law (Goodhart and Shoenmaker, 2006). Details on thirteen MoUs are reported in Table 2, summary statistics in Table 1. Overall, they distribute evenly both along the domestic/cross border dimension and according to the nature of signatory parties: (i) central banks; (ii) central banks and banking supervisory authorities; (iii) central banks, banking supervisory authorities and ministries of finance. Four main elements recur in such documents. First, the MoU sets out the responsibilities of the involved parties in respect to financial stability and, notably, crisis management. In doing so, as a rule, most if not all the key elements of the resulting outline are already defined, more or less explicitly, in the applicable legal framework. This is not meant to say that this section of the MoU is a trivial copy-and-paste: in fact, there is an effort in presenting the roles of the authorities in a plain, non-legalistic language. One could thus infer that, in effect, by signing a MoU the authorities mean to speak to an audience broader than the one versed in documents such as central banks statutes. Note that the text of the large majority (9 out of 13) of the consult- 20 Sveriges Riksbank (2003) clarifies that it is not sufficient that the value of assets is greater than the liabilities (given a fair evaluation) for an institution to be solvent. It is also necessary that the bank has the capacity to generate profits.

Domestic Cross-border total Central banks only Central banks and banking supervisory authorities Central banks, banking supervisory authorities and ministries of finance (treasuries) total ed MoUs is publicly available; where this is not the case, a sufficiently detailed press release has been issued. Furthermore, given the subject of this paper, it is highly relevant that an explicit reference to ELA can be found in six of the nine MoUs whose text is public and no MoU rules out this form of support. Second, the bulk of the MoU deals with improving the cooperation and the exchange of information among the signing parties notably when a crisis breaks out. Because of this, substantial attention is devoted to aspects of coordination and some crisis management committee is established. To avoid that such committee becomes rusty in the interval of time between one crisis and the next, regular gatherings are convened: on a monthly basis in the UK, at least quarterly in Sweden, periodically (with no defined frequency at least as far the text of the MoU goes) in the Netherlands, at least once a year in Denmark, monthly or more frequently in Australia. By contrast and perhaps surprisingly, no such need for regular gatherings is mentioned in the international MoUs. Third, the MoU outlines the conditions under which the procedures laid down in the MoU itself should be activated. The crisis situation is described in fairly general terms 21. But one element that clearly emerges is that it holds a system s dimension. 21 if either the RBA [the Reserve Bank of Australia] or APRA [the Australian Prudential Regulation Authority] identifies a situation which it considers is likely to threaten the stability of the financial system, it will inform the other as a matter of urgency (Australian MoU); if the financial situation within a financial enterprise or in a financial market is deemed to entail significant risks to financial stability, the issue shall be discussed by the Coordination Committee (Danish MoU). 22 By way of example, consider the MoU signed by the central banks of the European Nordic countries: The responsibility for managing a financial crisis in a bank rests primarily with its owners and management.. Thus, emergency liquidity assistance from the central banks will only be provided in exceptional circumstances, while the Danish MoU states: the four parties to the agreement shall seek to find solutions whereby owners of base capital and the board and management themselves bear the responsibility to the greatest possible extent. Likewise, the press release announcing the 2005 EU MoU states that: The memorandum of understanding should not be construed as representing an exception to (i) the principle of the firm s owners / shareholders primary financial responsibility, (ii) the need for creditor vigilance, and (iii) the primacy of marketled solutions to solve a crisis situation in individual institutions.
11 M. Manna - Emergency Liquidity Assistance at work: both words and deeds matter 165 Fourth, besides the exchange of information, two main lines of action are set out: (i) the primacy of market-led solutions and the fact that losses ought to be borne by the owners of the troubled institution in the first place; (ii) when any such option has been verified, no alternative is in sight and exceptional circumstances warrant, emergency lending assistance is called for 22. In short, those that have led the bank to the disaster ought not to benefit from the central bank s rescue through ELA (Goodhart, 1999). So much about the elements more frequently spelled out in the MoUs. What about those elements which one could expect to find there and, in fact, are less frequently mentioned? One such element is about the financial strings attached to the ELA (say, interest rate and maturity of the credit). As to the otherwise ubiquitous references on the illiquid-but-solvent issue, I was able to extract only one direct quote, from the Nordic MoU: one of the conditions for a decision to provide emergency liquidity assistance is that the bank in question is not judged to be insolvent. Another less-frequent element is the governance of the crisis management. With respect to the key question of which authority should have the final word on whether to grant the ELA or not, only a minority of MoUs offer clear guidance. One example is the UK MoU: Ultimate responsibility for authorisation of support operations in exceptional circumstances rests with the Chancellor. So does, albeit with different result, the Danish MoU: Where such public commitments are made, they shall be authorised by the competent authority. In this regard too, Danmarks Nationalbank shall independently make any decision concerning its own participation. A somewhat intermediate solution seems to be offered by the Dutch MoU: first, it states that DNB [the central bank] shall act as crisis manager. Within its powers, it shall take the measures it deems necessary if the urgency of the situation so requires, including the granting of special credit in exceptional cases, and subsequently it clarifies that Should developments at a financial enterprise or otherwise threaten financial stability, possibly requiring measures by the Minister, the Minister shall delegate a representative of the crisis management team formed by DNB. More or less along the same lines, the Nordic MoU clarifies that In cases where a bank is judged to be insolvent or where its solvency is deemed uncertain, the central banks are required to contact their respective Ministry of Finance immediately. IV. Straight from Walter s Mouth: Which conditions on ELA? It seems awkward to write a paper on ELA / LOLR without paying tribute to Walter Bagehot and his book Lombard Street (1873) 23. Using a measure of web-popularity such as the number of entries returned by a major 23 I used two versions of the book: an hard-cover book published by The Economist in 1978 and an electronic version at

Not a bad performance for someone who became famous for his writings on economic and financial affairs in 1860 he was became The Economist editor-in-chief but was not an economist by profession. Alas, when going through the quotes from Bagehot, this author seems to be victim of his own success to the point that his sentences seem to be taken in an acritical way and occasionally one may wonder if second-hand quotes are not passed on. To start with, in Lombard Street Bagehot self-assigned the objective of writing about what he called concrete realities, because he explains that the money market can be described in plain words, and the reader should not seek in his book for fixed rules, rather all nuances should be borne in mind to be appreciative of his lesson. Moreover, his analysis should be cast against the institutional settings prevailing at the time notably, the gold standard and the then internal organization of the Bank of England and some adaptations are in order to extract practical lessons for today s world. Let s revert to his original text on the scope of and conditions on emergency lending: The end is to stay the panic; and the advances should, if possible, stay the 24 By the same yardstick, Bagehot is dwarfed by Milton Friedman and John Maynard Keynes, but so would do most other well-established economists.
13 M. Manna - Emergency Liquidity Assistance at work: both words and deeds matter 167 panic. And for this purpose there are two rules: First. That these loans should only be made at a very high rate of interest... Secondly. That at this rate these advances should be made on all good banking securities, and as largely as the public ask for them 25. Quotes like this are often summarized by stating that emergency lending should be granted (i) at a high rate of interest, (ii) on good banking securities and (iii) freely. I shall now look at each of these three elements in turn. The high rate of interest First of all, high should not be read as penalty. In no instance, the p- word is used in Lombard Street next to the concept of the applicable interest rate. Indeed, Bagehot does not provide many details on this specific issue and the only safe element we have is his insistence that the central bank (the Bank of England) ought to step in at a relatively early stage of the crisis, before tensions mount excessively 26. Hence, the rate applied on ELA should be high compared to the pre-crisis levels but not necessarily higher than those prevailing at the peak of the crisis (if any market rate is then really available) 27. To gather more insights, a good starting point is the emphasis placed by Bagehot on the demand for reserves of the Bank of England originated outside and within the country, the foreign and domestic drain in his speak. With regard to the former, he argues in favour of a large reserve of legal tender because of the gold standard, he was concerned with large withdrawals of bullions from the country which needs to be protected by a rise in the rate of interest. In respect to domestic drain, Bagehot s recipe is simple enough: lend freely to restore trust in the market. Thus, if one fancies taxonomies, then he would associate the high interest rate to foreign drains and the free lending to the domestic ones. Now, because as observed repeatedly by Bagehot, the two maladies an external drain and an internal often attack the money market at once, the two tools often end up being jointly applied in this author s world. Perhaps for this reason, the tradition wants that, according to Bagehot, the interest rate should be raised in any crisis. In fact, disappeared the gold standard and if no external constraint such as some form of (soft or hard) currency pegging is binding, the foreign drain described by Bagehot becomes less likely. But then, a mainstay for charging high interest rates on the lending-of-last-resort fades. 25 Page 147 of the version of the book by The Economist (see fn. 23). 26 Bagehot clarifies that The rate should be raised early in the panic, so that the fine may be paid early; that no one may borrow out of idle precaution without paying well for it; that the Banking reserve may be protected as far as possible. 27 Goodhart (1999): Certainly the rate should be above that in effect in the market prior to the panic, but not necessarily above the contemporaneous market rate.
14 168 Studi e Note di Economia, Anno XIV, n One possible additional element of confusion may be the view that the hike in the interest rate is a way to contain the moral hazard: banks would refrain from applying for lending of last resort because this credit is dear. This interpretation could, in turn, reflect the notion that the high interest means to punish the banker that dared to request ELA. If that were the case, it would probably represent a light punishment indeed. Let follow a simple numerical example based on 2006 balance-sheet data of one of Italy s largest banks: firstly, take its gross outstanding exposure against all other banks; secondly, assume that out of the blue all its counterparts in the interbank market withdraw their credit; thirdly, the bank applies for an equivalent extraordinary lending by the central bank; finally, the latter one charges on the loan the current overnight interest rate plus five percentage points. Well, putting all these elements together a sequence which looks fairly extreme even against the vagaries of financial crises the extraordinary credit needs a maturity of more than 40 days to chop off just one tenth of the net annual income of the troubled bank. Really a bargain for the management that led the bank to sail in such dire straits! More credible looks the argument that banks do not easily apply for lending-of-last-resort because of a reputational risk. Indeed, it is widely accepted that even in a context of a widespread crisis, some elements of poor management should have been in place if the embattled bank (only one or a few out of many!) requested the extraordinary refinancing. Against this line of reasoning, the case for a high interest rate to any emergency lending weakens considerably. As convincingly argued by Martin (2005), in the aftermath of September 11 th the policy of the US Federal Reserve of keeping the federal funds rate very close to zero proved to be quite effective in managing a crisis potentially disruptive also from a financial standpoint. Weakening the case is not zeroing it. Bagehot argues in favour of a high rate of interest as a heavy fine on unreasonable timidity. His point is about denying the emergency credit to those firms that do not strictly require it. If more banks apply for the extraordinary refinancing and if, in the reckoning of the central bank, to meet only some of the bids suffices to tame the tensions, then a hike in the interest rate may well run the job of any price: the self-selection mechanism which eventually equals the demand for and the supply of a good in this case, the ELA. Otherwise, that is when it is one bank applying for ELA or when the central bank s action is geared towards a substantial loosening of the liquidity supply across the board (as the Fed after 11/9), it is not obvious why charging a high rate of interest should be the right policy in respect to ELA. On good banking securities As regards the guarantees, Bagehot s prescription is that LOLR should be granted against whatever in normal times is understood as good banking securities. The author is well aware of the fact that the identification of such
15 M. Manna - Emergency Liquidity Assistance at work: both words and deeds matter 169 a security becomes a complex task in crisis times and, it seems to me, he argues in favour of a pragmatic approach 28. A vivid example of the difficulty of sorting out good assets from a firm which typically would have few of them at the time it bid for ELA is offered by the role played by Freddie Mac CMOs among the assets guaranteeing the loan extended by the Federal Reserve Bank of New York to Bear Stearns in 2008 (see next section, in particular fn. 65). Asking questions on the quality of the guarantees backing an ELA is doomed to introducing a further reference to the issue of illiquid but solvent state of the bank, often associated with Bagehot s dictum. To cut a long story short can the central bank actually ascertain whether the bank applying for ELA is solvent or not within the tight time frame available for effective crisis management? it may suffice to observe that Bagehot did not really directly touch on the issue of insolvency. In fact, the reader is brought to understand that in this author s framework if a bank avails of good securities, then it is also solvent: the first concept in effect absorbs the latter one. The request for good banking securities was aimed mainly at protecting the Bank of England from possible losses. Noticeably, when Bagehot refers to the Bank of England, he had in mind mainly its then Banking department which acted, more or less, as an ordinary bank bar for the higher prestige it had acquired over the centuries 29. This may explain his concern about potential losses borne by the Bank and thus the need for acquiring good banking securities before granting the lending of last resort. Only at the margins, he mentions the Issuing department which was authorized to issue banknotes against Government securities and was closer in concept to a public institution. Shall this concern hold true today? Building on the results of an extensive survey of central banks financial conditions, Stella (2002) argues that if credibility is important for the success of its policies, the central bank should better be financially strong 30. It is beyond the scope of this paper to enter the fray of which authority should ultimately bear the costs associated with the support of critically-ill banks. To offer a flavour of the debate, the matter may be about size, namely if the central bank can bear on its books the losses orig- 28 if bankers for the most part advance on such security in common times, and if that security is indisputably good, the ordinary practice of the Bank of England is immaterial. In ordinary times the Bank [of England] is only one of many lenders, whereas in a panic it is the sole lender, and we want, as far as we can, to bring back the unusual state of a time of panic to the common state of ordinary times. 29 The Bank of England was a private institution and its capital strength was important as for any such institution. As to its Banking Department, this can no more multiply or manufacture bank notes than any other bank can multiply them even if All London banks keep their principal reserve on deposit at the Banking Department of the Bank of England (Bagehot, 1873). 30 The literature on central banks financial strength has gained new momentum in the light of the emergency lending carried out during the subprime crisis (e.g. Buiter, 2008). The Bank of Chile, which provides a counter-example of a central bank with a positive record in monetary policy making while operating with a negative capital, is widely regarded only as an exception to the rule.
16 170 Studi e Note di Economia, Anno XIV, n inated by an ELA, then she will be in charge, otherwise it will up to government (albeit likely acting on the advise by the central bank and the supervisory authority) to decide on how to best handle the crisis (Goodhart, 1999). Alternatively and perhaps more conventionally, the financial position of the troubled bank is regarded as the discriminating element: if the bank is clearly insolvent, then the government is in charge (Freixas et al., 2000), otherwise there may be a presumption for a direct role of the central bank. Thirdly and unsurprisingly, the proponents of the free banking school argue against any public intervention at all (Dowd 1988). Lend freely The concept of lend freely contains a hard and a soft dimension. The former is the one most typically remembered: the central bank should not fix quotas or maximum amounts of ELA but rather meet all the demands for the extraordinary refinancing, so long as the troubled bank is able to stack good banking securities and is willing to pay the required interest rate. It seems to me however that the key (but less often stressed) message rests with the latter dimension, the soft one. This deals with communication. Let us turn once more to Bagehot: What is wanted and what is necessary to stop a panic is to diffuse the impression, that though money may be dear, still money is to be had... To lend a great deal, and yet not give the public confidence that you will lend sufficiently and effectually, is the worst of all policies; but it is the policy now pursued 31. The message cannot be misunderstood: what matters most is not the volume of emergency lending actually granted but rather the attitude of the central bank towards the availability of meeting any request of such lending (obviously, at given financial and non-financial conditions) and the outside perception of this attitude. To sum it up: large volumes of lending which are not supported by adequate communication could bring about little effect; conversely, if the psychological element the uncertainty which under a crisis leads market players to stop dealing even with reasonably sound counterparties is checked, then even small volumes of ELA may do wonders. The emphasis on communication raises a somewhat related policy issue. The set of actions to be pursued the central bank steps in at a early stage of the crisis and does so by injecting confidence even before than funds requires clear command lines so as to swiftly and effectively act under time pressure. In the end, the market expects to hear the voice of the authority at the helm loud and clear. 31 Page 79 of the version of the book by The Economist (see fn. 23).
17 M. Manna - Emergency Liquidity Assistance at work: both words and deeds matter 171 V. Crisis management at work To draw lessons on the concrete actions pursued by central banks, I review a few recent banking crises: Sweden in the early 1990s, United Kingdom in 1995 (Barings), United States in 2001 (after September 11 th ), Austria in 2006 and again United Kingdom and United States in (Northern Rock and Bear Stearns). In doing so, with the aim to focus on the actual crisis management, I will try to be brief on the events which led to the crises. The Sveriges Riksbank and the crisis of The Swedish crisis of took place against the backdrop of a typical boom-bust switch: after a prolonged phase of strong growth featuring i.a. overinvestment, especially in the real estate sector, and lowered credit standards by banks chasing for higher market shares in a newly deregulated market the economy entered a recession with diving property prices. Already by the end of 1990, reported credit losses were substantially higher than in earlier years (Englund 1999). In 1991, house prices started to dive and arrears from lending related to real estate to pile up. Finally, the fixedexchange rate policy requested high interest rates to support the Swedish krona, with a hike on the occasion of the EMS crisis in The combination of these events led the seven largest banks, accounting for nine tenth of the banking market, to accumulate losses for approximately 12 percent of Swedish. To manage the crisis, the Swedish Ministry of Finance, its central bank and the financial supervisory authority pursued four main lines of action. First, the stance of the public communication was kept open and transparent, geared towards the taxpayer who should feel reassured that her money was not going to be used to rescue the banks owners. Second, the aforementioned authorities set up a dedicated institution, the Bank Support Authority (BSA), to manage the support provided during the crisis, while facilitating the exchange of expertise between the three parties. Third, a broad political consensus was sought, to prevent the effectiveness of the adopted measures being jeopardised by political feuding 32. Fourth, the parliament approved in December 1992 a bank support guarantee, which protected the banks creditors but not the banks shareholders; quite crucially, no upper limit was set for the State support (Ingves and Lind 1996). To customize the intervention, banks were ranked according to a three-tier scale (Andersson and Viotti 1999). A bank was classified as of type A if its capital ratio was forecast to decline toward but remaining above the 8 per cent limit, as of type B if the capital ratio could temporarily decline below the 8 percent limit (but not below nil) and in any case the bank was expected to 32 The political opposition was represented in the board of the BSA.
18 172 Studi e Note di Economia, Anno XIV, n regain profitability in the medium term, and as of type C if no such expectation was in place so that its capital ratio was eventually bound to become negative. The source of the support changed accordingly: the problems of a A- Bank could be solved by its shareholders, possibly with some temporary extension of the State guarantee; those of a B-Bank required, besides the capital injection by the shareholders, a more extensive State guarantee; finally, a C- bank was closed or merged with another bank in sounder financial conditions. Overall, the crisis management can be judged as a success story, if already in 1995 the Swedish banking system reported, on aggregate, strong profits. Over a shorter horizon, no major signs of a general lack of trust towards the domestic financial system mounted, although some occasional larger-thanusual cash withdrawals from banks were recorded. As to the wider effects on the economy, on the hindsight symptoms of credit crunch appear to have been fairly short lived. Because of the general bank guarantee provided by the State, there was no need for more direct government intervention in individual banks. As it turned out, the banking system outside of Nordbanken and Gota recovered, partly with new equity from their owners (Englund, 1999). The Bank of England and the collapse of Barings in 1995 Barings Bank was the oldest merchant banking company in London until its collapse in 1995 due to the financial positions taken by one of its employees, Nick Leeson. The main facts behind the Barings case are well known 33. In 1992 Leeson was appointed general manager of Baring Securities Limited, located in Singapore, where he was also head trader and de facto head of the back office. His trading in futures and options (run through the famous accounts) led to cumulated losses of some 208 million by December 31 st, Such losses were hidden and he had arranged for reporting handsome profits. By February 27 th, 1995, the accumulated losses spiralled to 830 million, leading to Barings demise. In a nutshell, the crisis ultimately owed to the serious failure of controls and managerial confusion within Barings (Bank of England, 1995a). From a crisis management point of view, the fact that the crisis escalated at speed light had the potential to foster widespread panic in the markets 34. On February 24 th, Friday Barings staff in Singapore phoned Barings headquarters in London with the news on the immense losses hidden by Leeson in his five-eight account. After a frantic search for more information and possible solutions, on late February 26 th, Sunday the 33 Information on the Barings collapse is available from a number of sources, including The Bank of England Report into the Collapse of Barings Bank (1995) and Leeson own account of the crisis is his book Rogue Trader (1996, E. Whitley co-authored). 34 One-quarter of Barings gross losses were incurred on a single day (Reserve Bank of Australia, 1995) and it is reckoned that if only Leeson s game had been unveiled by end 2004, Barings could have remained solvent. In the ensuing notes I follow a series of articles by E. Ipsen for the International Herald Tribune, appeared on 27 and 28 February and later on 3 March 1995.
19 M. Manna - Emergency Liquidity Assistance at work: both words and deeds matter 173 Bank of England announced that there would have been no rescue for Barings, as a result of which the troubled bank was put into administration 35. Two explanations were brought forward. First, the full scale of damage at Barings was unclear, an element which likely made other institutions potentially interested in the sale of Barings highly cautious. Second, Barings was judged not systemically relevant and not worth an injection of cash directly by the Bank itself; ELA was however one of the options on the table, even it is hard to assess from the outside how close was the extraordinary liquidity injection to become a reality 36. However, panic reactions in financial markets could not be ruled out and on February 26 th the Bank of England (1995b) announced its readiness to provide liquidity to the banking system to ensure that it continues to function smoothly. The aim was clearly one of building trust by making it clear that aggregate liquidity supply would have been kept adequate; incidentally, a message with little difference in the substance was echoed by the Fed in the aftermath of September 11 th (see below). In fact, not much happened in the markets: on February 27 th, Monday, spreads between Treasury and eligible bank bills widened only fractionally for a short time and swap spreads were unchanged, while in the equity market there was less selling than expected and the FT-SE 100 fell only by 0.4%. To recap, the Bank of England announced its readiness to provide ample liquidity, fulfilling the Bagehot s tenet of lend freely ; note that no mention was made of penalizing the demand for liquidity by hiking the interest rate (another element of similarity with the policy pursued by the Fed on 11/9). It also assessed the risk for financial stability at a system s level: having judged Barings not systematically relevant, it rejected the option of a direct cash injection to the troubled bank. Once again, crafting an appropriate, non-hesitant communication from the central bank towards the financial market likely played an important role in the overall crisis management. This should not be perceived as less pivotal only because Barings was not a major player, when measured by the scale of its operations in the city. Indeed, the news brought a shock if the Chancellor of the Exchequer, Mr. Kenneth Clarke, stated before the Parliament that This failure is, of course, a blow, to the City of London. The Federal Reserve in the aftermath of September 11 th, 2001 An almost real-time effect of the attacks against the World Trade Center, obviously aside the huge loss of life and property, was the virtual halt of many New York-centred financial markets. From September 11 th through 35 It was only a few days later that administrators for Barings PLC reported that they were in talks with the Dutch bank Internationale Nederlanden Groep (ING) NV. ING purchased Barings for the nominal sum of 1 along with assumption of all of Barings liabilities. 36 The reckoning of a low risk of contagion was restated by the then Governor of the Bank of England, Sir Eddie George, who was quoted by press sources that the collapse does not indeed have serious wider implications for other institutions.
20 174 Studi e Note di Economia, Anno XIV, n th, when eventually more ordinary conditions started to resume, the transfer of liquidity in the interbank market was at a standstill. Some intermediaries were materially not able to conduct business as a direct result of the disruptions caused by the attacks e.g. Bank of New York, one of the two main clearing banks, had its headquarters evacuated 37. Other banks found it difficult to locate borrowers, also because disruptions wracked telephone equipments (McAndrews and Potter, 2002). Finally, irrespective of the actual state of payment and communication systems, most banks and dealers took a prudent stance refraining from making payments until later than normal in the day before being reassured about their general cash position (Federal Reserve Bank of New York, 2002). Thus, market coordination failures added to objective difficulties in trading. Some mitigating factors were at play, however. First, there was no run to banks in the United States. Currency in circulation increased only by 0.7 per cent in the first two days after the attack, of which two thirds of the increase reflected larger banks vault cash holdings 38. Second, the incident that had brought the markets to a halt was clearly identifiable and it can be classified, in the dry taxonomy of financial crises, as an operational shock rather than as a credit shock; in a related way, solvency of relevant market players was not in doubt. The Federal Reserve reacted with firm communication and a substantial loosening of liquidity conditions. On September 11 th, at 9:44 it broadcasted a first message over the Fedwire, declaring that the system was fully operational at this time and will remain open until an orderly closing can be achieved. This was followed at 11:25 by a press release announcing: The discount window is available to meet liquidity needs. Because the ordinary policy is to limit the borrowing from this window, which is usually accepted only when an institution is deemed to have exhausted alternative sources of credit 39, the announcement was (correctly) interpreted as a marked shift in stance by the Federal Reserve, towards a robust liquidity easing; this interpretation was supported by additional words from senior Fed officials Also because of the communication and operations difficulties, this bank could not initiate payments on Fedwire, resulting in a large accumulation of funds (with a backlog of payments reckoned in the order of USD 100 billion, Lacker, 2004). 38 My calculations on data from Lacker (2004). 39 To avoid an easy arbitrage opportunity at the time, the discount rate was normally set lower than the federal funds target rate and thus generally below also the money market rates the funds obtained through this window were not meant to be re-lent in the interbank market and, more broadly, a strict moral suasion was enforced (in ordinary conditions). As a result, on aggregate the discount window usually contributed only marginally to the total Federal Reserve refinancing. 40 The Fed is the lender of last resort. If credit is needed to make transactions go, the Fed will provide it ; I am sure that central bankers everywhere will do everything possible to maintain calm and seek to ensure the world economy functions smoothly in the face of this horrendous deed (statements from Fed Governor E. Gramlich and the New York Fed President W. McDonough, see Lacker, 2004).
