The Plaza Accord was signed between Japan, the United Kingdom, France, West Germany, and the United States in 1985, aimed at reducing the imbalance in trade between the countries. At that time, Japan had a huge trade surplus, as the Japanese yen was weaker against U.S. dollar, while the United States suffered from a consistent trade deficit. The reason behind the accord was partially complaints by the US regarding the imbalance in the exchange rate between the yen and the dollar, since most Japanese products imported in the States had higher quality and lower prices than the domestic products due to the weaker yen against the dollar. After reaching a settlement in the Plaza Accord, central banks in participating countries started selling U.S. dollars. In Japan's case, demands for yen increased, and the yen appreciated significantly. In 1985, the exchange rate of yen per dollar was 238. After the foreign exchange intervention followed by Plaza Accord, the exchange rate dropped to 165 yen per dollar in 1986 as yen appreciated. This impacted exports in Japan to the States significantly, almost halving them in 1992 from their peak in 1986, whereas the trade deficit in the United States shrank after the Plaza Accord and the deficit cleared out in 1991. Due to the appreciation in the yen, Japanese companies suffered from huge losses in exports, as they had to sell their products in the States at higher prices than before to make a profit.
