Islamic Banking plays critical roles in providing essential economic function and service to the entire financial system and the overall economy. Thus, the bank’s strength and resilience is the foundation and pre-condition for achieving sustainable economic growth, given that banks are the centre of the credit intermediation process between savers and investors. One of the main causes of past financial crisis was that the banking sector had built up excessive both on-and-off balance sheet levereage and the transmission of external shocks. Therefore, this research mainly aimed to find the macroeconomic indicators that will signal the emergence of external shocks and adversely affect the resilience of Islamic banking. This research involves Indonesia and Malaysia to study the macroeconomic indicators using index as the assessment or methodology. The period of study is starting from 2010 to June 2019. The objective of this research ultimately to obtain the tolerable limits of shocks that will contribute towards the resilience of Islamic banking. This research finally suggests that leading indicators for resilience of Islamic banking are exchange rate and GDP. In addition, In the policy making’s point of view, the exchange rate stabilization and GDP advance should be more concerned rather than the price stability in order to ensure the exchange rate and GDP are fluctuating in the tolerable limits.
