Vanna-Volga Pricing

Methodology

Vanna-Volga pricing represents a robust framework for interpolating implied volatility surfaces in options markets where liquid strikes are limited. This approach specifically addresses the smile and skew dynamics by calibrating the volatility surface using three distinct points: the at-the-money forward volatility, and the volatilities of the 25-delta call and 25-delta put. By decoupling the market-observed premium into components sensitive to spot and volatility changes, practitioners gain a precise mechanism to value exotic structures.
