This paper analyzed the connection between exchange rate devaluations and
banks' hedging behavior. We argued that the presence of government guarantees
to banks' creditors completely eliminates banks incentives to hedge exchange
rate risk. So while the policy lowers the interest rate on bank loans and raises
aggregate output, it comes at a cost. The banking system becomes fragile. In the
event of a devaluation, banks renege on their debt and go bankrupt.
