The Effect of Money Market Liquidity Pressure on Banks’ Loan Loss Provisioning Composition: Evidence from General and Specific Provisions

Abstract:   (297 Views)
This study examines how money-market liquidity conditions affect banks’ loan-loss reserving behavior in Iran, with a focus on the composition of reserves between general and specific provisions. Here, liquidity conditions refer to short-term funding stress in the money market that raises banks’ funding costs and limits access to short-term financing. Because these conditions are not directly observable, they are proxied by the level and volatility of the interbank market rate, which captures liquidity conditions within the banking system. Given the Central Bank’s regulatory framework, which distinguishes between general and specific provisions and imposes a “base-deduction” rule, adjustments in reserving behavior are expected to be reflected more clearly in reserve composition than in the aggregate level of reserves. The empirical analysis uses a semiannual panel of 29 Iranian banks over 2021H1–2024H2 (232 bank-half-year observations) and estimates fixed-effects models with cluster-robust standard errors. After controlling for credit risk, bank size, capitalization, profitability, and overdraft dependence, the results indicate that higher interbank rates are associated with changes in the share of specific provisions in total reserves under certain time-control specifications. However, this relationship is sensitive to model specification and should therefore be interpreted with caution. By contrast, no robust evidence is found that money-market liquidity conditions significantly affect the intensity of either specific or general provisions relative to gross loans. Credit risk remains positively and significantly associated with specific-provision intensity. Overall, the findings suggest that reserve-composition measures provide useful supplementary information for financial reporting analysis and prudential supervision, while highlighting the challenges of identifying the effects of common time-series policy variables and the need for bank-specific liquidity measures in future research.
