    FX Options: Mind the Gap Between the Model and the Market

    Why do FX options sometimes behave very differently from what the pricing formula suggests? In this episode of The Trading Floor, Luigi Pascal Rondanini explores the gap between financial models and the realities of the foreign exchange options market. Models such as Black-Scholes, local volatility, stochastic volatility and SABR are essential tools—but every model is a simplification. Professional skill lies in recognising when a model is providing a useful approximation, when its assumptions are breaking down, and when model risk is becoming a material trading or hedging risk. The episode introduces Luigi’s forthcoming book: FX Options: Pricing, Hedging, Exotics, Risk and Institutional Practice Book Two of the Foreign Exchange Markets Professional Series The discussion covers: FX option pricing and volatility surfaces The difference between model risk and market risk Hedging with forwards, vanilla options and exotic structures Delta, gamma, vega and practical Greeks management Corporate treasury hedging decisions Volatility trading and relative-value strategies Black-Scholes, SABR, local volatility and stochastic volatility Why judgement matters more than the formula alone The book draws on Luigi’s experience trading FX derivatives and advising corporate treasurers, risk managers and institutional clients.
