This study attempts to investigate the aggressive and highly risky financing behaviour of Islamic banks operating in Malaysia. Particular reference was given to Islamic banks' credit risk-weighted assets for the purpose of determining the state of aggressive risk-taking behaviour in relation to the level of debt financing undertaken. 15 Islamic banks operating in Malaysia were examined over a short period of four years from 2013 - 2016; primarily due to limitations afforded by Pillar 3 Disclosure availabilities. Regulatory guidelines were assessed via the Bank Negara Malaysia (BNM) 2015 Capital Adequacy Framework for Islamic Banking (CAFIB) in attempt to examine the Malaysian regulatory response to aggressive and highly risky financing of Islamic banks in Malaysia.
