آیا بانکداری اسلامی یک پوشش طبیعی برای چرخه های تجاری ارائه می دهد؟ شواهد از یک سیستم بانکی دوگانه

We examine the lending patterns in the Turkish Islamic banking over business cycles. We find that, similar to conventional banks, Islamic banks in Turkey exhibit procyclical lending pattern. We also find that Islamic bank lending does not show significant difference from conventional bank lending. The results conflict with some of the findings that indicate Islamic banks as natural stabilizers in the banking systems. We emphasize that regulatory amendments of the last decade that are effective on Islamic banks could induce these banks to lend procyclically. To test the validity of this conjecture, we empirically examine how the state of competition in the Turkish banking system affects bank lending across business cycles by disentangling the effects separately for Islamic and conventional banks. The results suggest that the degree of competition spur bank lending procyclicality at the same magnitude, confirming the convergence between Islamic and conventional banks in their lending patterns. We also discuss several other issues in Islamic banking which may lead to the procyclicality of lending.
