Expiration Pressure

Expiration pressure refers to the increased volatility and trading volume observed in financial markets as derivative contracts, such as options or futures, approach their settlement date. In the context of cryptocurrency, this often occurs on the last Friday of the month when large volumes of options contracts expire.

Market participants must decide whether to roll their positions into future dates, close them out, or allow them to exercise. This activity creates significant order flow imbalances, forcing market makers to adjust their hedging positions rapidly to remain delta neutral.

As the expiration time nears, the gamma of these options can increase, leading to amplified price swings as market makers buy or sell the underlying asset to manage their risk. This phenomenon is a critical component of market microstructure, as it influences price discovery and liquidity depth.

Traders monitor open interest levels to anticipate the potential impact on spot prices. Ultimately, expiration pressure represents a concentrated period of strategic interaction and risk management.
