The use of blanket guarantees in banking crises

Policymakers often use guarantees on bank liabilities to prevent or contain bank runs during systemic banking crises, but their success has been debated. Using a sample of 42 episodes of banking crises, this paper finds that blanket guarantees do help to reduce liquidity pressures on banks, but only partially since they do not stem withdrawals from non-residents. Withdrawals following the announcement of guarantees are much more pronounced for nonresident liabilities than for foreign-currency denominated deposits-which may also be held by residents-suggesting that the results on non-residents are not driven by foreign-currency risk but by concerns about the government's ability and commitment to honor the guarantee to non-resident liability holders.
