In 1920, Lochhead accepted a position at the
Chemical Bank in New York. Several years later, he was made the head of the bank’s Foreign Department. While there, he helped found The Foreign Exchange Club of New York and was elected its President.
Henry Morgenthau Jr. was appointed
Secretary of the Treasury in 1933. However, his lack of financial experience demanded a "brain trust" of advisers. Lochhead became Technical Assistant to Morgenthau in 1933, hired for his expertise in the field of finance and foreign exchange. Lochhead advised Morgenthau on the nation's domestic and foreign financial operations, and was primarily responsible for setting up the Government's "Foreign Exchange Department" under the newly established two billion dollar
Exchange Stabilization Fund. Working behind the scenes as Director of the fund, Lochhead was given complete control over its day-to-day management to successfully stabilize the external value of the dollar. He operated the fund at a profit, achieved a settlement of all foreign accounts every day, and never allowed the Treasury to become uncollateralized in its temporary holdings of foreign exchange. He kept the dollar stable, and did all the buying for foreign silver under the 1934
Silver Purchase Act The fund’s operations were confidential. ==The Universal Trading Corporation==
