Gamma Pin Risk

Analysis

Gamma Pin Risk, within cryptocurrency options, arises when a significant concentration of open interest exists at specific strike prices, creating a potential for amplified price movements as options are hedged. This concentration often occurs around the current underlying asset price, or at psychologically important levels, and is exacerbated by market makers dynamically hedging their positions. Consequently, as the underlying price approaches these strike prices, dealers must adjust their hedges—buying or selling the underlying—to remain delta neutral, potentially accelerating the price toward the ‘pin’ and inducing substantial volatility. The risk is heightened in markets with lower liquidity, where dealer hedging can have a disproportionate impact on price discovery.
