# Yen volatility persists amid interest rate shifts

Following a coordinated U.S.-Japan yen-buying operation on July 30-31, 2026, the Japanese yen faced renewed downward pressure. While the intervention initially lifted the rate to the ¥155-¥158 range, the currency subsequently traded back toward and surpassed the ¥159 level. By early September, the yen saw a sharp 2.4 percent increase to 156.25 JPY, eventually strengthening to the 152–153 range as market expectations grew for a Bank of Japan (BoJ) rate hike.

As of mid-September, the yen has faced renewed pressure, falling below the 155 JPY/USD threshold due to a strong U.S. Dollar and rising oil prices. Consequently, the BoJ is widely expected to raise interest rates by 25 basis points to 1.25% during its policy meeting ending September 18. Such a move would represent the highest interest rate in three decades, aimed at addressing inflation and stabilizing the currency. This domestic shift occurs alongside global volatility, as the U.S. Federal Reserve faces scrutiny regarding its own potential interest rate hikes and the U.S. Dollar Index rises toward 99.7 points.
