Thanks to this option, the holder receives foreign market returns in his domestic currency, whereby avoiding the adverse effect of fluctuations in exchange rates on his returns. For instance, assume a Japanese investor is bullish on the American equity market but concerned about the dollar appreciating against the yen. This investor will need to buy a call option on a certain American equity index. The option pays in Japanese yen the value of that index in a specific period of time (the option’s life) minus the exercise price.

This option is also known as a quanto option.
