Answer: The options are given below:
a. forward realignment arbitrage
b. triangular arbitrage
c. covered interest arbitrage
d. locational arbitrage
The correct option is C. Covered Interest Arbitrage
Explanation: Covered interest arbitrage is a technique whereby an investor uses a forward contract to hedge against exchange rate risk. Covered interest rate arbitrage is the practice of using favorable interest rate differentials to invest in a higher-yielding currency, and hedging the exchange risk through a forward currency contract.
Covered interest arbitrage is possible if and only if the cost of hedging the exchange risk is lower than the additional return generated by investing in a higher-yielding currency - hence the word, arbitrage.
When there is a small market or there exists a high level of competition, then the possibility will occur that the earnings on covered interest rate arbitrage will not yield much.
