Building the FX Vol Surface with Quant Insider

Building the FX Volatility Surface: From Delta Quotes to Dynamic Hedging

FX options are quoted in delta, not strike. This webinar explains how to build and use an FX volatility surface from the conventions used in live markets.

We will cover

content of the webinar

1. FX Quoting Mechanics: How the market quotes delta instead of strike (ATM, risk reversals, butterflies), and the closed-form math required to invert them.
2. Vanna-Volga Replication: A 3-pillar technique to interpolate the smile. It is exact at the pillars but naturally unstable when extrapolated past the 5–95 delta range.
3. Local Vol vs. SABR: Dupire’s local vol provides an exact market fit but suffers from wing fragility; SABR offers smoother, stable, and dynamic spot-vol correlations.
4. Hedging Regimes: Sticky-strike vs. sticky-delta models. Choosing a regime isn't cosmetic—it fundamentally alters your dynamic hedge ratio via the vanna effect
