Covered Interest Arbitrage
Covered interest arbitrage is a strategy in which investors exploit differences in interest rates between two countries while hedging against exchange rate risk using forward contracts. By borrowing in a country with lower interest rates and investing in a country with higher rates, and simultaneously locking in the exchange rate through a forward contract, the investor earns a risk-free profit. The "covered" aspect of the strategy refers to the use of forward contracts to eliminate currency risk.
Example
An investor borrows funds in Japan at a low-interest rate, converts the money into U.S. dollars, and invests in U.S. bonds with a higher interest rate, simultaneously locking in a future exchange rate using a forward contract.
Key points
• Covered interest arbitrage involves exploiting interest rate differences between countries while hedging currency risk with forward contracts.
• The strategy generates risk-free profits by locking in exchange rates and taking advantage of higher interest rates abroad.
