We investigate whether the introduction of Islamic Deposit Insurance (IDI) affects deposit flow of and the pricing by Islamic banks vis-à-vis conventional banks for the case of Indonesia. Using December 2014 announcement of a separate deposit insurance scheme for Indonesia’s Islamic and traditional banks into two different funds as an exogenous event, we analyze the change in the growth of deposits, the number of accounts, and the pricing by Islamic and conventional banks in a difference-in-difference (DID) setting. Our findings indicate that the announcement significantly boosts the growth of small deposits in Islamic banks compared to traditional banks, with an apparent increase in deposit growth after separating deposit insurance funds.
