The asset reallocation channel of quantitative easing. The case of the UK

Abstract

We investigate the impact of the Bank of England's asset purchase program (APP) on the composition of assets of UK banks with unique data on the received reserves injections. The Monetary Policy Committee (MPC) didn't expect there to be strong transmission of the APP's impact through the bank lending channel. We find that compared to the control group, treated banks reallocated their assets towards lower risk-weighted investments, such as government se-curities, but did not provide more credit to the real economy. Overall, our findings suggest that when banks are not adequately capitalised, risk-based capital constraints can limit the effec-tiveness of expansionary unconventional monetary policies and provide incentives for carry trade activities.
