Currency Hedging

Hi all, what would be the best hedge against foreign currency fluctuations(to USD/) in an emerging market country. I need this for a fixed income locked account with decent return(tentatively) expected to be above the s&p 500 per annum. Tried forward contract on maturity but that practically wipes out all gains. Any others options to explore be it vanilla or exotic with least cost. Do tell all and thanks in advance.
