1 SUD ON EARL WARNING INDICAORS OF BANK RUNS IN INDONESIA: MARKOV-SWICHING APPROACH Ikandar Simorangkir * Abrac A run on a bank occur when a large number of deoior fearing ha heir bank will be unable o rea heir deoi in full and on ime imulaneoul r o wihdraw heir fund immediael. A run on a aricular bank can lead o a banking crii if i read o oher bank (conagiou effec). Bank run and banking crie have become a global henomenon and have occurred reeaedl in man counrie ince he era of modern banking. In he cae of Indoneia bank run have alo reoccurred ime and again. In 99 bank run affeced everal naional bank ubequenl reciiaing he liquidaion of one bank. hen in 997/998 bank run develoed ino he wor banking crii ever wineed in he banking hior of Indoneia.

A bank run i oenibl riggered b a lo of ublic confidence in a bank. hi lo of confidence can em from inernal bank facor like a decline in erformance a well a oher facor like an economic downurn or eernaliie like conagion.

Crii eerience gleaned in Aia during 997/998 indicae ha i wa a banking crii a one of he rimar facor cauing counrie in he region o uffer a evere economic conracion. he Indoneian econom eerienced he deee conracion reaching 3.% in 998. Meanwhile he economie of hailand Malaia Souh Korea and he Philiine eerienced reecive conracion in he ame ear of 0.5% 7.4% 6.9% and 0.6%. In addiion he co of rerucuring he banking ecor during he crii reached a whoing 45% of gro domeic roduc in Indoneia 5% in Korea and % in Malaia (Lindgren e. all. 999).

Anoher e of model ued o deec banking crie i an economeric model one of which i he logi model. Demirgüç-Kun and Deragiache (998) uilied a logi model o deec banking crie. In he reearch he oibili of a crii wa aumed a a funcion of he elanaor variable vecor wih he value of he deenden variable equal o 0 for no crii and in he even of a crii. Several auhor have conduced udie on earl warning indicaor for he financial ecor in Indoneia. Reearch underaken b Agung e al. (003) and Dewai e al.

4 . Bank Run and Earl Warning Indicaor Numerou earl warning indicaor (EWI) for individual bank were develoed uing reliminar emirical review in he mid-970. Reearch b Gonzalez-Hermoillo (999) oulaed ha he collae of a bank i caued b liquidi condiion he marke or credi rik. hee hree facor are cerainl affeced b he characeriic of an individual bank a well a macroeconomic condiion. In order o caure he imac of differen effec Gonzalez- Hermoillo (999) develoed a regreion model uing everal banking indicaor (like a ro of marke rik credi rik liquidi rik and moral hazard) in conuncion wih macroeconomic and regional variable. he reearch alo elicil inveigae how he collae of an individual bank can be affeced b financial ecor vulnerabiliie a a whole (for inance wih he conideraion of conagion). Secificall he reearch include a raio of oal credi o ouu a a meaure of banking ecor vulnerabili in a regreion. Congruou wih reearch conduced b he US Federal Deoi Inurance Cororaion (FDIC) in i earl warning indicaor em Gonzalez-Hermoillo (999) differeniaed beween indicaor of vulnerabili emming from rik facor ha can caue a bank o collae. In general an increae in non-erforming loan and a dro in he caial adequac raio are good indicaor of an imending bank collae. However onl a handful of main indicaor of a crii have been rooed for eimaing he collae of a bank. he mo alien oin of hee reearche include growh in roer credi and inerbank lacemen a indicaor of oible bank defaul. Converel higher credi aroval and a growing hare of radable ecuriie lead o a lower oibili of bank collae. Meanwhile conagion influence he collae of a bank in a number of cae bu he effec i minor. Davi and Karim (007) found ha heir reearch on earl warning indicaor (EWI) required he righ aroach among oher uing he logi mehod and ignal eracion. he differen mehod ued alo roduced differen erformance and crii redicion indicaor. he logi mehod garnered mo uor for a global EWI while ignal eracion wa found o be more counr ecific.

Meanwhile he variable choen o reflec he characeriic of he financial ecor were: M/foreign echange reerve and he level of bank credi growh wih a wo-eriod lag. In addiion GDP er caia wa ued a a ro for he rucural characeriic of he econom. he reul of he ud indicaed ha low GDP growh high real inere rae high inflaion and rong credi growh in he a a well a he magniude of he M raio o fore reerve imulaneoul rigger a higher incidence of banking crii.

Second i ha earl warning banking indur indicaor uing a correc and minimal andard deviaion (noie) o ignal have limiaion. hee limiaion neceiae he arbirar deerminaion of he banking crii hrehold value. Differen reearch aer have ued differen hrehold wihou roviding an rong argumen for he reaon wh. Eichengreen Roe and Wloz (996) e he crii hrehold a.5 andard deviaion from he mean while Kamink and Reinhar (999) e he hrehold a hree andard deviaion from he mean. In addiion he crii hrehold alo deend heavil on he ize of he amle. Addiional daa or longer eriod can aler he crii hrehold. he hird weakne i ha ranforming he crii inde ino binar can eclude relevan informaion. Due o he weaknee eoed when uing he robi/logi aroach and arbiraril deermining he crii hrehold he Markov-Swiching model i referable when inveigaing echange rae crie and banking crie. Uiliing hi model i no onl limied o idenifing he crii eriod bu i can alo be ued o redic he occurrence of banking crie. he ue of Markov-Swiching in analing or deecing he occurrence of banking crie ha a number of advanage. he fir advanage i ha he crii hrehold value i an endogenou variable or in oher word he crii eriod and i duraion form ar of he reul o be eimaed. Uing hi 5

Nonehele indicaor of boh ae can be oberved direcl b monioring behaviour in boh economic ae. he wo ae are differen wih a higher and more flucuaing value for a crii ae when comared o a ranquil ae (normal eriod). he hif in value from one ae o he oher deend on he raniion robabili. According o he characeriic of Markov he value of an ucoming ae deend on he curren ae. herefore hi model ermi he oibili of a crii ae remaining in a ae of crii. he econd advanage i ha he Markov-Swiching model allow he ue of coninuou deenden variable. Uing change in deoi or i inde can reven a lo of informaion if he daa i ranformed in he form of a dumm variable. he hird advanage of uing hi model i ha i can caure dnamic informaion from he crii. herefore hi model can be ued o eimae he duraion of he crii eriod from he robabili of he raniion eriod. he fourh advanage i ha hi model can be ued for non-linear behaviour. Uing Markov-Swiching o deec echange rae and banking crie ha develoed in recen ear due o he weaknee found in he ignal aroach namel arbiraril deermining he crii hrehold. Abiad (003) ued he Markov-Swiching aroach o anale an earl warning em for echange rae crie in Aia. Baed on hi reearch i wa found ha he model work well when deecing he occurrence of echange rae crie in Aia. he model could deec wo-hird of he crii eriod in he amle and creaed fewer fale ignal comared o he reviou model namel he ignal aroach. Reearch b Alvarez-Plaa and Schrooen (003) and Ho (004) alo roduced robu reul uing hi model o deec echange rae crie reecivel in Argenina and Aia. Meanwhile Ho (004) ued he Markov-Swiching model o deec banking crie uiliing aggregae daa. he reul of hi reearch howed ha hi model can uccefull deec banking crie in Aia. In he cae of Indoneia Agung e. al. (003) develoed an earl warning em o redic echange rae and banking crie b modifing he ignal eracion model develoed b Kamink Lizondo and Reinhar (999). he modificaion included ring o caure abnormal behaviour from he indicaor ued no individuall bu uing aggregae indice. hi wa underaken conidering ha leading u o a crii uch indicaor uuall move in union. he variable ued include: macroeconomic indicaor (real areciaion of he 6

Bank Performance amid a Crii A i oue he crii ha befell he Indoneian econom in 997 wa riggered b an echange rae crii on he ruiah. Inene dereciaor reure emmed from conagion from he bah echange rae crii haening in hailand in Jul 997. he affec of hi conagion no onl reached Indoneian hore bu alo read quickl o oher counrie in Aia like he Philiine Malaia and Souh Korea. he governmen inervened b inroducing economic olic ackage in Seember 997 in order o roec he domeic econom from a deeer crii a a reul of dereciaor reure and caial ouflow. hi rogram wa ubequenl eended o become an economic abiliaion and reform rogram garnering he formal uor of he IMF World Bank and ADB in November 997. In he imlemenaion of hi financial ecor reform rogram o reore he banking em 6 naional rivae bank were cloed on November 997. he cloure of 6 bank riggered wideread bank run on hoe bank deemed unound b he general ublic. Conequenl he olic o cloe bank which hould have aved he naional banking indur acuall rovoked bank run on bank no owned b he ae. hee bank run occurred due o a collae of ublic confidence in he banking indur due o he bank cloure. A he bank run read he financial erformance of all bank began o uffer wih credi loe and lower bank earning due o oor managerial racice ha did no adhere o aec of good governance (Wario 00 and Bank Indoneia 998). In addiion raid ruiah dereciaion welled he foreign deb of bank denominaed in ruiah which wa eacerbaed furher b he lack of a guaranee rogram. he abence of a guaranee rogram and lack of informaion regarding he condiion of he bank (ammeric informaion) forced he bank cuomer eeciall he cuomer of rivae bank o wihdraw heir deoi and diver hem o bank conidered more ound wih afer ae (currenc). 997/998 Bank Indoneia Financial Reor. 7

Meanwhile he validi of he MS model wa eed a an earl warning indicaor of bank run hrough a comarion wih acual incidence of bank run. a. Sae-Owned Bank (BP) Signal of bank run in he Markov-Swiching (MS) model can be oberved from he raniion robabili value of changing from a ranquil ae (no bank run) o a ae of bank run. A value of more han 0.5 imlie a greaer hen 50% chance of bank run and a value of mean he robabili ha rien o 00%. Converel if he value i 0 hen he robabili of bank run i zero. he reul of he MS model for ae-owned bank indicaed var rare incidence of ignal of bank run (able ). Such condiion are refleced b a raniion robabili from ranquil o crii of 0 for nearl all monh in he amle eriod. Of he 47 monh under obervaion for each individual bank onl 6 indicaed he oenial occurrence of bank run for BP 7 monh for BP 5 monh for BP3 4 monh for BP4 and 5 monh for BP5 wih value in he range of 0.7 o. However hee ignal of bank run were no erien a refleced b a dro in value from 0.7- down o 0 (Aachmen ) in he ubequen monh.
