USD/JPY rose after dipping to about 156.60 in Asia on Monday, moving back near 157.00. The pair followed Friday’s rebound from 155.50–155.45, the lowest level since 25 February, but momentum remained limited.
The US Dollar found support as Middle East tensions increased. US President Donald Trump said the US would guide neutral ships out of the Strait of Hormuz under “Project Freedom”, and said disruption would be met “by force”.
Geopolitical Risk And Rate Expectations
Iranian parliament National Security Commission head Ebrahim Azizi warned that US interference in the waterway would breach a ceasefire. Minneapolis Fed President Neel Kashkari said a prolonged Iran conflict could raise inflation risks and harm the economy, and raised the possibility of higher rates.
Reports said Japanese authorities likely intervened around 1 May, spending about ¥5.4 trillion ($34.5 billion) to support the Yen. That may limit further USD/JPY gains.
With no major US data due on Monday, the pair may react mainly to further Middle East developments. The Yen is influenced by Japan’s economy, Bank of Japan policy, US–Japan bond yield gaps, and shifts in risk sentiment.
We are seeing a familiar pattern as USD/JPY tests the 162.50 level, where strong US dollar demand clashes with the growing threat of Japanese intervention. This creates a tense environment for traders, as the potential for a sharp, sudden move is increasing daily. The core conflict is between fundamental economic divergence and direct currency market action by authorities.
This situation feels very similar to what we experienced around this time in 2025, when the pair was consolidating near 157.00. Back then, Middle East tensions and hawkish Federal Reserve commentary supported the dollar, much like today’s geopolitical anxieties and stubborn US inflation are doing. The key takeaway from 2025 is that even with strong fundamental support for a higher USD/JPY, the fear of intervention can cap the upside for weeks.
Yield Differentials And Intervention Risk
The primary driver remains the interest rate differential, which has only widened. As of late April 2026, the yield on the US 10-year Treasury note stands at 4.8%, while the Japanese 10-year government bond offers just 1.1%, maintaining a significant carry trade appeal. Recent US inflation data coming in hotter than expected at 3.6% has further pushed back expectations of Fed rate cuts, reinforcing dollar strength.
However, we must respect the Ministry of Finance’s willingness to act, as it creates significant downside risk. We all remember the suspected ¥5.4 trillion intervention in May of 2025, which caused a rapid drop in the exchange rate. Japanese officials are again issuing verbal warnings, which historically precede direct market action when the yen’s decline is seen as too rapid.
For derivative traders, this suggests that long volatility strategies could be profitable. Buying a USD/JPY straddle or strangle allows a position to profit from a large price move in either direction, whether it’s a breakout above 163.00 or an intervention-fueled plunge towards 158.00. This approach is beneficial when the direction is uncertain but the likelihood of a significant price swing is high.
Alternatively, for those who believe intervention is not a matter of if but when, buying JPY call options (or USD/JPY put options) is a direct way to position for a stronger yen. This strategy provides a defined risk, limiting potential losses to the premium paid for the option. Given the historical precedent of sharp, multi-yen drops post-intervention, these options could offer a favorable risk-reward profile in the coming weeks.
