Economics Working Paper 15115

Abstract:

This paper investigates the risk channel of monetary policy on the asset side of banks’ balance sheets. We use a factor-augmented vector autoregression (FAVAR) model to show that aggregate lending standards of U.S. banks, such as their collateral requirements for firms, are significantly loosened in response to an unexpected decrease in the Federal Funds rate. Motivated by this evidence, we reformulate the costly state verification (CSV) contract to allow for an active financial intermediary, embed the partial equilibrium contract in a New Keynesian DSGE model, and show that – consistent with our empirical findings – an expansionary monetary policy shock implies a temporary increase in bank lending relative to borrower collateral. In the model, this is accompanied by a higher default rate of borrowers.
