Interest arbitrage - "Interest arbitrage" is switching into another currency by buying spot and selling forward, and investing proceeds in order to obtain a higher interest yield. Interest arbitrage can be inward, i.e. from a foreign currency into the local one or outward, i.e. from the local currency to the foreign one.

Sometimes better results can be obtained by not selling the forward interest amount. In that case, some treat it as no longer being a complete arbitrage, as if the exchange rate moved against the arbitrageur, the profit on the transaction may create a loss.

Interest parity - One currency is in "interest parity" with another, when the difference in the interest rates is equalized by the forward exchange margins. For instance, if the operative interest rate in Japan is 3% and in the UK 6%, a forward premium of 3% for the Japanese yen against sterling would bring about interest parity.
