 He was Administrator-General of Provisions from 1736–1758.This post and his extensive network of contacts enabled him to exercise extensive influence over government policy.His record in managing the public debt in 1721 and monetary policy from 1724-26 was called into question by Nicolas Dutot in his work " 'les Réflexions politiques sur les finances et le commerce' ", and he defended himself by dictating, to his former cashier, François Deschamps, a two-volume work entitled " 'l' Examen du livre intitulé réflexions politiques sur les finances et le commerce' "which he had published at The Hague in 1740.
