Abstract We examine how changes in capital requirements and monetary policy shocks affect corporate investment during a credit boom. Our empirical analysis uses data on SMEs in the UK between 1998 and 2006, a period when monetary policy and microprudential regulation were set by independent institutions. We find that an increase in bank-specific capital requirements led to a contraction in corporate debt and investment, but only for firms with short bank relationships. This suggests that relationships between firms and banks are crucial for the transmission of regulatory shocks. Long relationships also attenuate the impact of monetary policy shocks, but to a smaller degree than for capital requirement changes. We also find that the two policies do not dampen or amplify the effect of each other, but their effects vary with the size of banks’ capital buffers and the creditworthiness of firms.
