Equity-Linked Foreign Exchange Options are options (see Figure 49.1) whose underlying asset is in a foreign equity market. The option holder can hedge the fluctuations of the foreign exchange risk by having a strike price on the foreign exchange rate. The resulting valuation is in the domestic currency. There are three closely related models in this chapter and the following two chapters (foreign equity-linked foreign exchange option, foreign equity struck in domestic currency, and foreign equity with fixed exchange rate in domestic currency). Their similarities and differences can be summarized as follow:

  • The underlying asset is denominated in a foreign currency.
  • The foreign exchange rate is domestic currency to foreign currency.
  • The option is valued in domestic currency.
  • The strike prices are different where:
  1. The exchange rate is the strike for the foreign equity-linked foreign exchange option.
  2. The domestic currency is the strike for the foreign equity struck in the domestic currency option.
  1. The foreign currency is the strike for the foreign equity with a fixed exchange rate in the domestic currency option.
