Gamma Inversion Phenomenon

Definition

The gamma inversion phenomenon occurs when the local gamma of an options position flips sign due to extreme underlying asset price movements or significant changes in implied volatility. In decentralized finance and crypto derivatives markets, this state transition forces market makers to reverse their delta hedging activity, effectively shifting from selling into rallies to buying into strength. Such behavior exacerbates market volatility, as the liquidity providers must aggressively adjust their exposures to maintain neutral delta profiles during rapid price discovery.
