Quick Definition

An option contract that can only be exercised at expiration, not before, typically found in index options and OTC markets.

What Is European Option?

A European option can only be exercised on its expiration date, not at any earlier time. Despite the name, European-style options are found worldwide and are not limited to European markets. Most index options (like SPX options on the S&P 500) are European-style, as are many OTC derivatives. European options are simpler to price analytically because there is no early exercise decision to consider — the Black-Scholes formula directly applies. They are typically less expensive than equivalent American options because they offer less flexibility. European options settle in cash rather than physical delivery of shares, which simplifies the exercise process. For non-dividend-paying underlyings, European and American call options have the same theoretical value since early exercise of a call is never optimal in that case.

European Option Example

  • 1SPX index options are European-style — a trader holding a $4,500 call cannot exercise early even if the S&P 500 surges; they must wait until expiration for cash settlement
  • 2A European put on a stock with no dividend has the same price as an American put only when the stock price is very high relative to the strike — otherwise the American put is worth more
