European Option Expiry Pinning

Context

European Option Expiry Pinning, within cryptocurrency derivatives, refers to a specific market intervention strategy employed near the expiration date of a European-style option contract. This technique involves market participants, often exchanges or large institutions, actively managing the option’s price to maintain a predetermined level, typically close to the underlying asset’s spot price. The primary objective is to prevent extreme price fluctuations and ensure orderly settlement, particularly when significant open interest exists. Such actions can influence the implied volatility surface and impact subsequent trading activity.
