Oil Falls, Yen Rises as U.S.-Japan Intervention Sparks Markets
On August 3, 2026, oil prices dropped because the U.S. President said talks with Iran would happen soon.
The U.S. and Japan worked together to buy yen, making the Japanese currency stronger.
The stock market in the U.S. went up a little, but Japan’s and South Korea’s markets went down.
A banker said the yen’s long‑term decline probably won’t stop, but the short‑term move might be temporary.
Some experts think the market will correct itself once the intervention ends.
Brent crude futures fell over 6% to $82.41 after President Trump announced Iran talks.
The U.S. and Japan jointly intervened in the yen market, lifting the currency above 155 per dollar.
S&P 500 and Nasdaq futures rose modestly, while Japan’s Nikkei and South Korea’s KOSPI fell.
Mizuho Bank strategist Masayuki Nakajima said the intervention likely won’t reverse the long‑term yen depreciation trend.
Market analysts warned that the intervention may be temporary and could correct once fundamentals resume.
