At the time of maturity, the money invested in the higher return currency will be taken out along with the interest and converted back to the lower return currency leading to an arbitrage profit. An arbitrageur executes a covered interest arbitrage strategy by exchanging domestic currency for foreign currency at the current spot exchange rate, then investing the foreign currency at the foreign interest rate. Therefore, the one-year forward rate for this currency pair is X = 1.0196 Y (without getting into the exact math, the forward rate is calculated as [spot rate] times [1.04 / 1.02]).

When spot and forward exchange rate markets are not in a state of equilibrium, investors will no longer be indifferent among the available interest rates in two countries and will invest in whichever currency offers a higher rate of return. Statistical Arbitrage. Covered interest arbitrage in this case would only be possible if the cost of hedging is less than the interest rate differential.

Batten and Peter G. Szilagyi analyzed the sensitivity of forward market price differentials to short-term interest rate differentials. [1] Using forward contracts enables arbitrageurs such as individual investors or banks to make use of the forward premium (or discount) to earn a riskless profit from discrepancies between two countries' interest rates.

Using data from November 1, 1985 to May 9, 1986, he finds that deviations should be no mo re than 0.06 percent per annum. Economists Jacob Frenkel and Richard M. Levich investigated the performance of covered interest arbitrage strategies during the 1970s' flexible exchange rate regime by examining transaction costs and differentials between observing and executing arbitrage opportunities. Some covered interest arbitrage opportunities have appeared to exist when exchange rates and interest rates were collected for different periods; for example, the use of daily interest rates and daily closing exchange rates could render the illusion that arbitrage profits exist. Covered interest rate parity can be conceptualized using the following formula: Where: 1. a.
