Pricing of FX TARFs using a regime switching LSV model

We propose a finite-difference pricing method for FX Target Redemption Forwards (TARFs) within a local stochastic volatility (LSV) framework. The approach incorporates a multi-state regime-switching model for stochastic volatility, enabling fast and robust calibration. The local volatility surface is obtained in a single forward-sweep on the finite-difference grid. TARF valuation is achieved by solving coupled one-dimensional PDEs. Valuation results are compared with those from a Heston-LSV model. Numerical experiments demonstrate the stability and effectiveness of hedging TARFs with the proposed model.
