This paper shows a higher order discretization scheme for the Bismut--Elworthy--Li formula, the differentiation of diffusion semigroups. A weak approximation type algorithm with Malliavin weights is constructed through the integration by parts on Wiener space and is efficiently implemented by a Monte Carlo method. We give a sharp error estimate for the discretization based on Malliavin calculus. Numerical sensitivity analysis for the option delta in finance shows the validity of the proposed scheme.
