Summary

Story summary

Japan and the United States intervened on Monday, buying yen and pushing the dollar to 156.34 yen.
The intervention, the first U.S.–Japan yen-buying operation since 1998, involved Treasury officials considering a US$5-10 billion yen purchase with euros, a move described as unusual.
Central-bank data show Japan may have spent $36.58 billion buying yen, lifting the yen to 155.23 per dollar while the euro fell from about 187.4 yen to below 180 yen.

History

Historical Context

The 1985 Plaza Accord, signed by the United States, Japan, West Germany, France, and the United Kingdom, forced coordinated currency realignment. Within two years the yen surged from roughly 240 per dollar to about 160, a 33% appreciation that pressured Japan’s export-driven economy. Today's joint U.S.–Japan yen-buying effort mirrors the Plaza Accord’s aim to curb excessive yen strength, but now seeks to halt yen weakness amid dollar-yen 156 levels. If the intervention succeeds, it could echo the 1980s policy shift, stabilizing exchange rates and influencing future fiscal coordination among the Treasury, Federal Reserve, and Bank of Japan.
