Expansionary Monetary Policy and Bank Loan Loss Provisioning

Abstract

We explore how expansionary monetary policy (EMP) influences bank loan loss provisioning. We find that banks’ discretionary loan loss provisions (DLLPs) increase during periods of EMP. This effect is stronger for banks with greater risk-taking, a larger proportion of influential stakeholders, lower ex-ante transparency of loan loss provisions, and more stringent bank regulation, which is consistent with external stakeholders requiring more conservative and timelier loan loss provisioning. We also find that both the timeliness and the validity of banks’ loan loss provisions (LLPs) increase during EMP periods. Our results are robust to the use of instrumental variable estimation and exogenous variations in monetary policy. Lastly, we show that conservative (i.e., higher DLLPs) and timely loan loss provisioning discipline banks from excessive risk-taking during periods of EMP.
