This article assesses how shocks to bank capital may influence a bank's portfolio behaviour using novel evidence from a UK bank panel data set from a period that predates the recent financial crisis. Focusing on the behaviour of bank loans, we extract the dynamic response of a bank to innovations in its capital and in its regulatory capital buffer. We find that innovations in a bank's capital in this (precrisis) sample period were coupled with a loan response that lasted up to 3 years. The international presence of UK banks allows us to identify a specific driver of capital shocks in our data, independent of bank lending to UK residents. Specifically, we use write-offs on loans to nonresidents to instrument bank capital's impact on UK resident lending. A fall in capital brought about a significant drop in lending in particular, to Private Nonfinancial Corporations (PNFC). In contrast, household lending increased when capital fell, which may indicate that, in this precrisis period, banks substituted into less risky assets when capital was short.
