Staff Working Paper No. 1,173

By Angus Foulis, Jonathan Hazell, Atif Mian and Belinda Tracey

This paper estimates how rate cuts increase consumption, via debt and asset prices. Using administrative UK data on mortgages and consumption, we exploit the expiry of fixed-rate mortgages to construct six million household-level natural experiments. A 1 percentage point reduction in mortgage rates raises consumption by 3% in the following six months. Using plausibly exogenous variation in how house prices respond to rate cuts, we show that consumption increases mostly because households borrow against higher house prices; lower debt service after rate cuts matters less. These results suggest that in large part, monetary policy affects consumption through asset prices and borrowing.
