We investigate the transmission of changes in bank capital requirements and monetary policy, and their interaction, on German banks’ corporate loan growth and lending rates. Our results show that increases in capital requirements are associated with an immediate decrease in total domestic and cross‐border bank lending. Changes in the euro area's monetary policy stance are positively related to corporate loan interest rates in general. Regarding the interacting effect of national bank capital requirements and euro area monetary policy, we observe that the transmission of accommodative euro area monetary policy to corporate lending rates can be attenuated by contemporaneous increases in bank capital requirements. Moreover, more strongly capitalized banks increase their loan growth in response to accommodative monetary policy whereas, for weaker banks, increasing capital requirements implies a decrease in their corporate loan growth. Our results confirm a tradeoff between higher capital requirements and accommodating monetary policy originating from banks’ capital constraints.
Given buoyant capital inflows and managed exchange rates the majority of emerging market central banks have continued to accumulate massive foreign reserves. If left unsterilized, the liquidity expansion can threaten domestic macroeconomic stability. To contain domestic inflation these central banks absorb rather then provide liquidity in their regular monetary policy operations. Based on an augmented Barro-Gordon framework we show that inflation targeting within an environment of surplus liquidity is less efficient, because absorbing liquidity raises the costs of monetary policy operations. By implementing sterilization costs into the central bank's objective function the inflation bias increases. JEL-Code: E52, E58.
