Basel II and bank lending behavior: some likely implications for monetary policy

The new Basel accord is slated to come into effect in India around 2007 raising the question of how the revised standards will influence bank behaviour. Using a simple theoretical model, it is shown that the revised accord will result in asymmetric differences in the efficacy of monetary policy in influencing bank lending. This will, however, depend on a number of factors, including whether banks are constrained by the risk-based capital standards, the credit quality of bank assets and the relative liquidity of banks’ balance sheets. The basic model is empirically explored using data on Indian commercial banks for the period 1996-2004. The analysis indicates that the effect of a contractionary monetary policy will be significantly mitigated provided the proportion of unconstrained to constrained banks in the system is significantly high
