We model interest rate and portfolio determination under the risk of real currency devaluation taking into account risk aversion on the part of investors. A simple extension of the Friedman-Savage analysis of consumer behavior under uncertainty to a two period, two country setting allows us to explicitly solve for the interest rate premium paid in the risky asset. The model is applied to the 1979-1980 Argentinean experiment with the pre-announced exchange rate. Empirical results suggest that a safety factor, central bank reserves as a fraction of M2, is closely related to the net ex ante and ex post arbitrage differentials in favor of Argentina relative to the United States.
