Volatility Surface Interpolation
Volatility Surface Interpolation is the process of estimating implied volatility for option strikes and expirations that do not have actively traded market prices. Because liquidity in cryptocurrency options is often concentrated at specific strikes, traders must use models like cubic splines or SABR to fill in the gaps.
This surface represents the market expectation of future volatility across the entire options chain. Accurate interpolation is critical for pricing exotic derivatives and managing portfolio risk.
It ensures that the Greeks, such as Vega and Vanna, are calculated consistently across all positions. Poor interpolation can lead to arbitrage opportunities or significant mispricing of complex derivative structures.
