Gamma margin is a supplementary collateral requirement designed to cover the risk associated with changes in a position’s delta. While delta margin covers first-order directional risk, gamma margin addresses the second-order risk, which is the rate at which delta changes as the underlying asset price moves. This margin component is particularly crucial for options portfolios that are delta-hedged, as it accounts for the cost of rebalancing the hedge in response to price fluctuations.
Risk
The primary risk mitigated by gamma margin is the non-linear exposure of options positions. High gamma indicates that the delta changes rapidly with small movements in the underlying price, requiring frequent and potentially costly rebalancing of the hedge. The gamma margin ensures sufficient capital is available to cover these rebalancing costs, especially during periods of high volatility when price changes are large and frequent.
Volatility
Gamma risk is directly correlated with market volatility; higher volatility increases the likelihood of significant price changes that necessitate rebalancing. The calculation of gamma margin often incorporates volatility estimates to accurately assess the potential cost of maintaining a delta-neutral position. This dynamic adjustment ensures that margin requirements reflect the current market environment, protecting against unexpected losses from rapid delta shifts.
