What Is a “Volatility Surface” and How Is It Used in RFQ Pricing?

A volatility surface is a three-dimensional plot that shows the implied volatility for all available options on a given underlying asset, plotted against both the option's strike price and its time to expiration. Market makers use the volatility surface to ensure consistency and accuracy when pricing an RFQ.

Any quote must align with the current surface to avoid being picked off. It is the core reference for calculating the fair value of any option derivative.
