The most common statistical method for European FX options pricing follows the Garman-Kohlhagen model, which calculates a log-normal process. It is a modification of the well-known Black-Scholes Model for standard option pricing and takes the two risk-free interest rates of a currency pair into account. Foreign Currency Option Values, Garman-Kohlhagen – Macroption In the standard Black-Scholes option-pricing model, the underlying deliverable instrument is a non-dividend-paying stock. The solution proceeds analogously to Merton’s description of the proportional-dividend model, replacing his dividend rate d by the foreign interest rate, as The Garman Kohlhagen model is used to price Foreign Exchange (FX) Options. An FX Option involves the right to exchange money in one currency into another currency at an agreed exchange rate on a specified date. Valuation: the Garman–Kohlhagen model . As in the Black–Scholes model for stock options and the Black model for certain interest rate options, the value of a European option on an FX rate is typically calculated by assuming that the rate follows a log-normal process.

Mathematically, the formula is identical to Merton's (1973) formula for options on
Valuing FX options: The Garman-Kohlhagen model As in the Black-Scholes model for stock options and the Black model for certain interest rate options, the value of an european option on a FX rate is typically calculated by assuming that the rate follows a log-normal process. This was adapted for FX options by Garman and Kohlhagen in 1983, and the Garman-Kohlhagen model remains the default for FX options today. Many trading systems and treasury management systems allow the user to choose between Garman-Kohlhagen, Cox-RossRubenstein, and binomial models amongst others. Using the dollar/euro exchange rate as input for parameter estimation and employing our FX option model as a yardstick, we find that the traditional Garman-Kohlhagen FX option model, which assumes · FX Specific (Garman-Kohlhagen): there are several functions available. · There are many versions of calls and puts with barriers, average-based, on spreads, baskets. We recommend searching under the specific option type. Garman–Kohlhagen: Formula for estimating the value of a European call option on foreign exchange. It assumes the risk-free interest rate (being paid on the foreign currency) as a continuous dividend yield, and avoids the Black Scholes option pricing model's assumption that borrowing and lending takes place at the same interest rate.

Both the Garman Kohlhagen and generalized Black Scholes models are derived under a fairly restrictive set of assumptions, including: 1. The stochastic behaviour of the underlying exchange rate is assumed to be well represented by a Geometric Brownian Motion process. Foreign Currency Option Values, Garman-Kohlhagen – Macroption In the standard Black-Scholes option-pricing model, the underlying deliverable instrument is a non-dividend-paying stock. The solution proceeds analogously to Merton’s description of the proportional-dividend model, replacing his dividend rate d by the foreign interest rate, as
