By law, the Treasury controls dollar policy. It's the only area where the Fed is required to march to the elected government's music.

But that's figuring dollar policy narrowly - interventions, which are rare (and on which the Fed and Treasury actually make a profit, despite market declarations of their futility). The early-80s dollar strength was determined by larger forces, like high interest rates and a perception that Reagan's U.S. was a great place to invest. If you were a portfolio manager, where would you park your money, in a U.S. committed to deregulation and disinflation or a France committed to regulation, nationalization, and reflation? The relative fates of the dollar and the franc in the early 1980s were at least as much symptoms as they were causes of anything - symptoms of capital movements.

But that couldn't last forever: the high dollar was savaging U.S. exports, and Reagan had won the policy battles on a world scale. So the Plaza agreement was a nice psychological catalyst for a shift in currency values that was in line with the fundamentals.
