External Factors Influencing JPY
The Japanese Yen (JPY) has increased by 0.4% against the US Dollar (USD), despite being weaker compared to other G10 currencies amid widespread USD weakness. Current JPY increases are mainly due to external changes and decreased rate expectations for the Fed, resulting in narrower yield spreads that support the JPY.
Markets are focused on upcoming key GDP and industrial production data in Japan, though recent movements are driven by external factors. For USD/JPY, a bearish trend is anticipated, targeting a break below the mid-146 to mid-148 range that has characterised price movement since early August.

Based on the current environment, we see the US dollar losing ground against the Japanese yen due to shifting expectations around US interest rates. This is narrowing the yield spread between US and Japanese government bonds, which is the primary driver of the yen’s recent strength. We believe this trend has more room to run in the near term.
The latest US inflation data from July 2025, which showed the Consumer Price Index cooling to 2.8%, reinforces this view. This has pushed the market to price in a higher probability of the Federal Reserve holding rates steady, causing the US 10-year Treasury yield to dip below 3.9%. These external factors are currently more significant for the yen than Japan’s domestic economic picture.
Domestic Outlook and Derivative Strategies
On the Japanese side, preliminary data for second-quarter 2025 GDP showed a modest expansion of 0.5%, slightly ahead of market consensus. While not a major catalyst on its own, this positive surprise provides a supportive backdrop for the yen. It removes a potential headwind and allows traders to focus on the more dominant story of US dollar weakness.
Given the bearish outlook for the USD/JPY pair, we should consider derivative strategies that profit from a downward move in the coming weeks. This could involve buying USD put options or JPY call options with strike prices below the 146.00 level. We are targeting expirations in late September or early October 2025 to give the trade time to play out.
We must also manage the risk that this trend could reverse. The mid-146 to mid-148 range has served as a strong floor for the pair since the beginning of August. A decisive break above the 148.50 level would signal that our bearish view is likely incorrect, requiring a reassessment of our positions.
Looking back, this setup has historical parallels. We saw a similar dynamic in late 2023 when a rapid shift in market expectations for a Fed policy pivot caused the USD/JPY to fall significantly from its cycle highs. The current situation feels like a smaller-scale version of that event, suggesting a potential for a swift move lower if the 146 support level fails to hold.
