プラザ合意
The Plaza Accord () was a joint–agreement signed on September 22, 1985, at the Plaza Hotel in New York City, between France, West Germany, Japan, the United Kingdom, and the United States, to depreciate the U.S. dollar in relation to the French franc, the German Deutsche Mark, the Japanese yen and the British Pound sterling by intervening in currency markets. The U.S. dollar depreciated significantly from the time of the agreement until it was replaced by the Louvre Accord in 1987. Some commentators believe the Plaza Accord contributed to the Japanese asset price bubble of the late 1980s.
