This paper investigates the role of the exchange rate regime in asimple Fisherian model of the overborrowing syndrome. Where domesticbanks are subject to moral hazard, the choice of exchange rate regimemay have important implications for the macroeconomic stability of theeconomy. Banks that enjoy government guarantees have an incentive toincrease foreign borrowing and incur foreign exchange risks that areunderwritten by the deposit insurance system. In the absence of capitalcontrols, this increases the magnitude of overborrowing and leaves theeconomy both more vulnerable to speculative attack and more exposed tothe real economic consequences of such an attack.
While "bad"exchange rate pegs will tend to exacerbate the problem of overborrowingin emerging markets, it is unclear that flexible exchange rate alwaysdominate fixed exchange rates. A "good fix" -- one that is credible andclose to purchasing power parity -- may reduce the "super risk premium"in domestic interest rates and thereby narrow the margin of temptationfor banks to overborrow internationally. Contrary to the currentconsensus regarding the lessons that should be drawn from the Asiancrisis, a good fix may better stabilise the domestic economy whilelimiting moral hazard in the banking system.
