Banking Panic Risk and Macroeconomic Uncertainty

Abstract

We show that systemic risk in the banking sector breeds macroeconomic uncertainty. We develop a model of a production economy with a banking sector where financial constraints of banks can lead to disastrous banking panics. We find that a higher probability of a banking panic increases uncertainty in the aggregate economy. We explore the implications of this banking panic-driven uncertainty for business cycles, asset prices and macroprudential regulation. Banking panic-driven uncertainty amplifies business cycle volatility, increases risk premia on asset prices and yields a new benefit from countercyclical bank capital buffers.
