The United States secretary of the treasury is the head of the United States Department of the Treasury, and is the chief financial officer of the federal government of the United States. The secretary of the treasury serves as the principal advisor to the president of the United States on all matters pertaining to economic and fiscal policy. The secretary is, by custom, a member of the Cabinet of the United States and, by law, a member of the National Security Council. Under the Appointments Clause of the United States Constitution, the officeholder is nominated by the president of the United States, and, following a confirmation hearing before the Senate Committee on Finance, is confirmed by the United States Senate. The secretary of state, the secretary of the treasury, the secretary of defense, and the attorney general are generally regarded as the four most important Cabinet officials, due to the size and importance of their respective departments. The current secretary of the treasury is Janet Yellen, who is the first woman to hold the office. From Wikipedia
