  • Abstract

A novel second-order numerical scheme for solving decoupled forward back-ward stochastic differential equations is proposed. Unlike known second-order schemes for such equations, the forward stochastic differential equations are approximated by a simplified weak order-2 Itô-Taylor scheme. This makes the method more implement-able and enhances the accuracy. If the operators involved satisfy certain commutativity conditions, the schemewith quadratic convergence can besimplified, which is important in applications. The stability of the method is studied and second-order optimal error estimates are obtained.
