US Secretary of State Cordell Hull led the American delegation to the conference. Roosevelt ordered Hull not to enter into any discussions on currency stabilization. However, when the Conference had gathered, Roosevelt changed his mind by supporting currency manipulation to raise prices and having American banking experts Oliver Mitchell Wentworth Sprague and James Paul Warburg conduct currency stabilization talks with their British and French counterparts. By June 15, Sprague, Warburg, Montagu Norman of the Bank of England, and Clement Moret of the Bank of France had drafted a plan for temporary stabilization.
