Because of the risk of exchange-rate change, this can result in a loss and is therefore not truly a form of arbitrage. Sometimes called the carry trade.
Uncovered interest parity Equality of expected returns on otherwise comparable financial assets denominated in two currencies, without cover against exchange risk. Uncovered interest parity requires approximately that i = i* + a, where i and i* are the domestic and foreign interest rates and a the expected annualized percentage appreciation of foreign currency.
