Bank runs and currency peg credibility

It is shown that as a currency peg constrains a governmentʹs ability to finance a bailout, bank runs are more likely in credible fixed exchange rate regimes than in those in which the central bank is less committed to its exchange rate. Within the context of the model and given the government responses to their respective banking crises during the period 1994-1995, the bank runs in Argentina and lack thereof in Mexico seem to be rational responses of depositors.
