## Option Assignment Risk

Option assignment risk is the danger that a short option position will be exercised by the long holder, requiring the seller to fulfill the terms of the contract. For a short call, this means delivering the underlying asset, while for a short put, it means buying the underlying asset at the strike price.

This risk is particularly high for American-style options that can be exercised at any time, especially near expiration or when dividends or significant price events occur. In cryptocurrency markets, assignment risk can be exacerbated by sudden price spikes that trigger automatic exercise by counterparty systems.

Traders must ensure they have the necessary collateral or assets to meet these obligations if they are assigned. Failing to manage assignment risk can lead to unintended long or short positions in the underlying asset, which may be difficult to exit profitably.

It is a core operational risk for anyone selling options.
