US dollar weakens sharply against the Japanese yen after market interventions

The U.S. dollar experienced a significant drop against the Japanese yen on Monday, August 3, 2026, following confirmed market interventions by both the United States and Japan. Prior to late last week, the dollar had been trading above 163 yen, reaching an all-time high of 40 years. However, after suspected regulatory interventions, the dollar plummeted below 160 yen.

Following the official announcement of the intervention, the dollar depreciated by approximately 1%, reaching 156.34 yen, a substantial shift in the exchange rate.

The yen's prolonged weakness against the dollar has been a persistent issue for Tokyo. As Japan imports a large portion of its consumption, a weaker currency leads to higher prices, contributing to inflation. Previous attempts to raise the yen's value against the dollar in the past year have not yielded significant results. Last week, the U.S. side was suspected of providing assistance.

When questioned about the U.S. involvement, President Donald Trump stated, "We have a good relationship with Japan. We're very strong - very, very strong financially - and they are, you know, they have a weakening yen, and they wanted a little bit of help, and we're always there for Japan. Japan's been very good to us, with the exception, of course, of Pearl Harbor."

Trump further added that the U.S. gained "financial benefit" from the intervention, calling it a "signal of friendship" and beneficial for the world economy.

In Tokyo, Finance Minister Satsuki Katayama confirmed the intervention, stating that the ministry had coordinated with the U.S. Treasury Department to purchase yen. This move came in response to a joint statement from last year and aimed to counter excessive volatility and disorderly movements in the Japanese yen over recent months. The ministry expressed readiness to take further action if deemed necessary.
