Interest rate options sit at the intersection of market convention, quantitative modeling, and live risk management, and small misunderstandings in any one of those areas can become costly on a rates desk. This book is written for swaption traders, structured rates professionals, junior quants, and risk managers who need a practical, desk-ready guide to how swaptions are actually priced, quoted, modeled, and hedged in modern markets.
The book takes the reader from the foundations of curves, swaps, forward rates, annuity, and multi-curve valuation into the full practitioner toolkit for swaptions. It covers product definitions and market quoting, Black-76 and Bachelier pricing, the normal-versus-lognormal choice, volatility smiles and surfaces, SABR dynamics and calibration, and implementation-level greeks under different conventions. It then moves beyond theory into hedge construction, delta-gamma and vega management, P&L explain, cap/floor linkages, relative-value structures, and the market consequences of the LIBOR-to-SOFR transition.
What distinguishes this treatment is its focus on the workflow of a real rates volatility desk rather than on isolated formulas. The presentation is structured to help readers connect model choices to tradable risks, surface behavior, hedge slippage, and market structure. A working familiarity with fixed income and derivatives is helpful, but the progression is designed to build the necessary framework in a clear, self-contained way.
