At the Plaza Hotel in 1985, five governments agreed to push the dollar down.
If money is tight, a cheaper dollar can mean dearer imports at the store.
If you are in the middle, a factory that exports gets a lift and a household that buys imports pays.
If you have savings, overseas earnings and domestic exporters are revalued by a meeting.
On September 22, 1985, the United States, Japan, West Germany, France, and Britain announced the Plaza Accord.
They wanted a weaker dollar after a long climb.
The dollar fell.
