AbstractWe investigate whether diversification stabilizes bank lending cyclicality on a sample of 25 conventional and 18 Islamic banks from Malaysia spanning 2008 to 2021. Our findings reveal that both bank types are nonlinearly procyclical during economic expansions, with Islamic banks also exhibiting countercyclical behavior during economic contractions. Diversification is positively associated with credit growth in conventional banks and Islamic bank subsidiaries, and it amplifies procyclicality across all Islamic bank types. Conversely, loan concentration stabilizes credit in Islamic banks. These results are robust to an alternative credit measure. Further analyses indicate that public and foreign banks are procyclical during booms and countercyclical during busts. At the same time, diversification heightens procyclicality in private, local, and foreign banks, whereas concentration mitigates it in public and local banks.
