We analyze government interventions in the eurozone banking sector during the 2008–2009 financial crisis. Using a novel data set, we document that fiscally constrained governments “kicked the can down the road” by providing banks with guarantees instead of fully-fledged recapitalizations. We econometrically address the endogeneity associated with bailout decisions in identifying their consequences. We find that forbearance prompted undercapitalized banks to shift their assets from loans to risky sovereign debt and engage in zombie lending, resulting in weaker credit supply, elevated risk in the banking sector, and, eventually, a greater reliance on liquidity support from the European Central Bank.

A two-sided “credit-line channel”—relating to drawdowns and repayments—explains the severe drop and partial subsequent recovery in bank stock prices during the COVID-19 pandemic. Banks with greater exposure to undrawn credit lines saw larger stock price declines but performed better outside of crises periods. Despite deposit inflows, high drawdowns led to reduced bank lending, suggestive of capital encumbrance upon drawdowns. Repayments of credit lines unencumbered capital which explains the stock price recovery starting Q2 2020. Bank provision of credit lines resembles writing put options on aggregate risk, and we propose how to incorporate this feature into bank stress tests.
