USD/JPY reversed after a close at 159.19, having earlier reached 159.34 before ending at 158.96 (+0.03%). Prior guidance pointed to a 158.80–159.25 range, but the pair held a tighter band of 158.87/159.23, then finished at 159.19 (+0.14%) before dropping sharply. While the pull-back has not materially increased downward momentum, the pair may test 158.70; a sustained move below that level is viewed as unlikely, with 158.40 described as strong support. Near-term resistance is seen at 159.05 and 159.25.
Over a one- to three-week horizon, the stance remains positive, although upward momentum is described as slowing. The analysis frames 158.40 as the pivot that would shift the outlook from positive to neutral. On the topside, a push above 159.45 is seen as possible, but any further advance is not expected to challenge the 2024 high at 162.00. Reference is also made to 21 May, when spot was at 158.85.
Macro Drivers and Policy Gap
We see the US dollar holding its strength against the yen primarily due to the significant interest rate difference between the US and Japan. Recent US inflation data from early May 2026 came in at a stubborn 3.1%, reinforcing expectations that the Federal Reserve will not be cutting rates soon. This contrasts with the Bank of Japan, which has signaled it will move very slowly, maintaining a policy gap that favors the dollar.
Our view is that while the trend for USD/JPY remains positive, the upward momentum is fading, making a significant breakout unlikely in the immediate future. The key level we are watching is the 158.40 support; as long as the pair holds above this, the bullish outlook remains intact. Historical data shows that Japanese authorities become more vocal about intervention as the pair approaches the 160.00 level, which naturally slows down speculative buying.
Option Strategies and Trading Range
For derivative traders, this suggests selling out-of-the-money put options with strike prices below the 158.40 support level for expirations in the next two to three weeks could be a viable strategy to collect premium. A more defined-risk approach would be to implement a bull put spread, such as selling a 158.50 put and buying a 157.50 put. This strategy profits if the USD/JPY stays above 158.50 by expiration.
Given the slowing momentum and the risk of intervention from the Ministry of Finance, the upside seems capped around the 159.45 to 160.00 area for now. This makes selling call spreads with strikes above 160.50 another potential trade to consider. Combining these strategies could create a profitable range as long as the pair avoids any major shocks and stays between roughly 158.40 and 160.50.
