1 Communication in Monetary Policy: Experiences of the Swiss National Bank Thomas J. Jordan and Enzo Rossi Swiss National Bank Universität Siegen, 24 June 2006 Conference on Zentralbankkommunikation
2 Structure of presentation 1. Introduction 2. Results of the literature 3. Consensus view of central bankers 4. SNB s monetary policy concept 5. SNB s communication experiences 6. Challenges 7. Conclusions
3 1. Introduction Remarkable change in central banks attitude over time: Transparency now deemed beneficial instead of detrimental Significant increase of transparency at central banks Increased importance of communication in monetary policy strategies
4 2. Results of the literature Burgeoning literature No unique concept of transparency In general: transparency relevant if asymmetric information Provision of knowledge about all aspects of the monetary policy strategy Disclosure of all information relevant for understanding monetary policy decisions
5 Theoretical results Positive impact of transparency: Increase in reputation, elimination of inflation bias, reduction of market uncertainty Negative impact of transparency: Potentially harmful for macroeconomic stability Transparency more important for central banks with poor credibility than for those with high credibility No straightforward guidance from theory for designing transparency and communication policy in practice
6 Mainly favorable empirical evidence Higher transparency leads to: Reduction of inflation and sacrifice ratios Diminishing sensitivity of inflation expectations to past inflation Enhanced flexibility for reactions to shocks Increased predictability of monetary policy
7 3. Consensus view of central bankers Transparency Counterbalance to institutional independence and delegation of authority Necessity for monetary policy effectiveness Effective communication Means of increasing transparency, accountability and credibility Support of policy intentions Optimal transparency and communication set-up may differ from country to country
8 4. SNB s monetary policy concept Transparency and Communication Definition of price stability Inflation forecast Target range for 3M- Libor Nominal anchor and ultimate objective of monetary policy Main indicator Operational target
9 Inflation Forecast June 2006 Assumption: steady three-month Libor of 1.50% (June) vs. 1.25% (March) % 3.0 2.5 2.0 Price stability 1.5 1.0 0.5 0.0 00 01 02 03 04 05 06 07 08 09
10 Target Range and 3M-Libor % 4.5 4.0 3.5 Target range Aimed level 3M-Libor 3.0 2.5 2.0 1.5 1.0 0.5 0.0 Jan 00 Jan 01 Jan 02 Jan 03 Jan 04 Jan 05 Jan 06
11 Some remarks about the concept Definition of price stability as nominal anchor for monetary policy; but no inflation target Inflation forecast as main indicator but not as intermediate target Operational target: some flexibility to dampen shocks Broadly based set of information (suite of forecasting models, monetary aggregates, ) Quarterly meetings to review monetary policy; unscheduled meeting possible if immediate decision necessary
12 Elements of SNB communication Description of monetary policy concept Description of set of relevant information variables and forecasting models Announcement of scheduled policy meetings Communiqué and press conference after policy decisions with publication of inflation forecast and target range for 3M- Libor Quarterly Monetary Policy Report Speeches and interviews Annual Accountability Report
13 5. SNB s communication experiences Communication and transparency central elements of SNB monetary policy since the end of the Bretton Woods system Significant step forward with new monetary policy concept Conviction: Effective communication not only important for accountability but a prerequisite for monetary policy efficiency However, transparency not for the sake of transparency Continuous and careful refinement of communication policy and strategy
14 Communication of policy concept Detailed description of the monetary policy concept Announcement of scheduled policy meetings Publication of forecasting models Indication of set of relevant information variables (exchange rates, money aggregates,...) Allowing markets to draw similar conclusions from incoming data
15 Communication of policy decisions Publication of target range for 3M-Libor Additional indication: 3M-Libor aimed to remain in upper, middle or lower part of target range Elaborated communiqué and press conference after meeting Publication of inflation forecast (no fan-chart; constant interest rate hypothesis) Detailed quarterly Monetary Policy Report No publication of minutes or transcripts of policy meeting
16 Transparency for money market Weekly publication of relevant data for money market participants: Assets and liabilities of the SNB Compliance of banking sector with minimum reserves Results of monetary policy transactions (terms, bids and allotments)
17 Management of expectations SNB manages expectations by providing: Interpretation of published inflation forecast Information about likely future policy course Conditions for further policy adjustments Escape clauses (e.g. exchange rate development) But no publication of future path of 3M-Libor and no mechanical reaction to inflation forecast Example: Normalization of monetary policy by gradual tightening (December 2005 - )
18 Gradual tightening 2005-2006 % 2.00 1.75 1.50 1.25 1.00 0.75 0.50 15. Sep 15. Okt 15. Nov 15. Dez 15. Jan 15. Feb 15. Mrz 15. Apr 15. Mai 15. Jun 3M Libor Aimed level 1st generic 3M future
19 Policy surprises: Increased consistency in views due to effective communication However, on occasion diverging views Policy surprises indispensable and often unavoidable and not harmful for credibility of central banks if understandable Examples: March 2000: 75 bp interest rate hike March 2003: begin of near-zero interest rate policy
20 Surprise March 2003: Term structure % % 0.90 3.25 0.80 0.70 0.60 0.50 0.40 0.30 0.20 0.10 0.00 EUR 7.3.03 (rhs) EUR 5.3.03 (rhs) CHF 5.3.03 (lhs) CHF 7.3.03 (lhs) money market rates; source Reuters T/N 1W 1M 2M 3M 6M 12M 3.00 2.75 2.50 2.25 2.00 1.75 1.50 1.25 1.00
21 Surprise March 2003: EUR/CHF 1.58 1.56 1.54 1.52 1.50 1.48 1.46 Rate decision 1.44 Nov 02 Dez 02 Jan 03 Feb 03 Mrz 03 Apr 03 Mai 03 Jun 03 Jul 03
22 Avoiding confusion Only few people involved in communication Concentration on relevant information Discipline of policy makers: homogeneous view of Board members Official press release as base document for contact with public and markets
23 Successful communication of SNB Positive response from public and markets Successful steering of interest rate expectations Successful monetary policy: price stability and firm inflation expectations for more than a decade No confusions in markets about SNB s intentions To a large extent congruent analysis of SNB and markets No evidence of missing elements in communication
24 6. Challenges Nature of published inflation forecast: Evaluation of different possibilities Policymakers loss function: Is high specification possible and desirable? Right amount of information: Trade-off between openness and clarity
25 Publication of inflation forecasts I Conditioned on fixed interest rates (unchanged policy): Advantages: Simplicity; clear interpretation No agreement on future path for interest rates necessary Disadvantages: Potential model-specific inconsistencies Inflation forecast not comparable with forecasts from forecasting institutes
26 Publication of inflation forecasts II Conditioned on policymakers intended interest rate path: Advantages Realistic assumption Prediction of future interest rates Disadvantages: Misunderstanding with repercussions on central bank credibility if interest rate path regarded as commitment Complicated agreement among policymakers about future interest rates
27 Publication of inflation forecasts III Based on current market expectations of short-term rates Advantages: No agreement among policymakers for optimal path of future interest rates necessary Derived from public information Disadvantages: Limited forecastability of the market Unclear interpretation of inflation forecasts Computation of market expectations not straightforward
28 Specification of SNB s loss function SNB mandate: Ensuring price stability by taking development of the economy into account Definition of price stability; but no specification of output stabilization objective Difficulties with explicit loss function: Primary vs. secondary objective Level vs. volatility objective Aggregating policymakers preferences Interpretation for the public
29 Correct amount of information Risk of confusion due to surplus of information: Limited digestibility of information Trade-off between openness and clarity Unintended market reactions Finding ideal balance between quantity and quality of information
30 7. Conclusions No communication panacea available Communication policy country-specific and dependent on monetary policy concept as well as on central bank s history SNB s communication fairly successful so far Communication and transparency steadily changing Trendy concepts not risk-free
