RISK OF INDONESIAN BANKS: AN APPLICATION OF HISTORICAL EXPECTED SHORTFALL METHOD

Asian and European crises were witnesses of banks’ vulnerable due to market risks. The Basel Committee requires an internal risk assessment applying Value at Risk (VaR). However, a replacement of VaR with Expected Shortfall (ES) has been suggested recently due to an excessive losses produced by banks which are beyond VaR estimations. This paper studied the risk of Indonesian banks applying a historical expected shortfall. We used JIBOR (overnight) from 2009 – 2012 as a proxy of market risk. The assessment of a historical expected shortfall of the net position of 27 banks accounts for October 2012 showed that state owned banks placed among the five highest value of each component (net position) in the balance sheet, namely placement to Bank Indonesia, interbank placement, spot and derivatives claims, securities, and loans. It means that the state owned banks had the highest risk and were the most aggressive among Indonesian banks. It might be due to carrying some of the government’s program, such as small enterprise loans.     Keywords: expected shortfall, value at risk, banks, risk.   JEL Classification: D81, G210Asian and European crises were witnesses of banks’ vulnerable due to market risks.
