Banks have a biggest portion in Indonesia’s financial system. A shock to banking system would effect the resilience of financial system, where in turn it would dampen the resilience of banking system. This research aims at developing the conventional banking resilience index in Indonesia. The index is useful to help monitor the condition and level of conventional banking in Indonesia. The research uses secondary data from Bank Indonesia and financial services authority. The data covers some indicators, BOPO, NIM, CIR, CAR, ROA, Liquidity, LDR, Credit Growth, and NPL. The research employs indexation method with standardization approach since May 2003 to September 2016. The result show that the level of resilience of banking varies over the period of observation. The level of resilience is low in 2006 and 2007, mean while in 2008 and 2016 it’s level is normal. Therefore, Bank Indonesia as policy maker shold be able to maintain the resilience of conventional banks by taking care of indicator BOPO, CAR, and NPL. In addition Bank Indonesia should be prudent in implementing it’s policies, particularly concerning efficiency issue, capital, and credit during the crises.
