Vega Volatility Buffers

Definition

Vega volatility buffers are risk management mechanisms implemented in options trading to account for potential losses arising from adverse changes in implied volatility. These buffers represent an additional capital reserve or margin requirement specifically allocated to cover Vega risk, which is the sensitivity of an option’s price to changes in volatility. They act as a cushion against unexpected shifts in market sentiment. The goal is to mitigate volatility-driven losses.
