Hedging is a strategy used to protect against risks from currency fluctuations. Managers hedge currency risk by contracting to sell foreign currency in the future at the current exchange rate, locking in the rate to avoid losses from devalued currency. If managers correctly predict exchange rate movements, it boosts fund returns. There are risks to businesses and investments from changes in exchange rates. Hedging tools include forward contracts that lock in future rates and options that provide the right but not obligation to exchange currency.
