Abstract
This paper examines how monetary policy affects corporate lending through its impact on household balance sheets, bridging the gap between the cash flow and bank lending channels. When policy rates rise, households with variable-rate debt face higher monthly payments, prompting early mortgage repayments, particularly among high-income borrowers. Exploiting the monetary tightening between July 2022 and September 2023 as a policy experiment, we show that banks that are more exposed to variable-rate mortgages granted to higher-income households increase their supply of corporate credit, especially to micro and small firms. However, no variation is observed in the balance of household credit or in other investment items on the banks’ balance sheets. Indeed, banks facing higher liquidity constraints tend to extend more corporate credit as their exposure to early redemptions increases. Our findings provide new evidence on how household financial constraints shape monetary policy transmission, offering novel insights into the interplay between household debt dynamics and corporate credit allocation.
