Abstract:

Increases in firm default risk raise the default probability of banks while decreasing output and inflation in US data. To rationalize the empirical evidence, we analyse firm risk shocks in a New Keynesian model where entrepreneurs and banks engage in a loan contract and both are subject to default risk. In the model, a wave of corporate defaults leads to losses on banks’ balance sheets; banks respond by selling assets and reducing credit provision. A highly leveraged banking sector exacerbates the contractionary effects of firm defaults. We show that high minimum capital requirements jointly implemented with a countercyclical capital buffer are effective in dampening the adverse consequences of firm risk shocks.
