## How Does ‘Volatility’ (Vega) Influence an Option’s Premium?

Vega is the option 'Greek' that measures the sensitivity of an option's price to a 1% change in the underlying asset's volatility. Higher volatility means the underlying asset is more likely to experience large price swings, increasing the probability of the option expiring 'In-the-Money'.

Therefore, an increase in volatility always increases an option's premium, and a decrease in volatility lowers it.

A thin rod intersects the disk diagonally against a predominantly black background, suggesting calibrated measurement or directional bias within a trading matrix. This visual metaphor directly addresses the quantification of uncertainty endemic to digital asset options trading, particularly regarding automated market maker AMM performance under stress. The segmented circular element could model Greeks sensitivity analysis specifically focusing on Gamma scalping strategies against volatile crypto assets like Bitcoin or Ethereum. The industrial base speaks to the secure settlement layer required for derivative clearance, perhaps referencing underlying smart contract security audits or collateralized debt positions CDPs. Accurate modeling of non-constant volatility structure, perhaps via SABR or Heston models adapted for on-chain settlement, is crucial for calculating premium accretion rates and managing vega exposure across multi-asset synthetic positions prevalent in advanced crypto financial engineering."
