Oil supply disruption fears and a strong US dollar weigh on the yen, lifting USD/JPY further

    USD/JPY rose on Wednesday as the Yen stayed weak amid concern about Oil supply disruption linked to the US-Iran war. Japan depends heavily on imported energy, especially from the Middle East. The pair traded near 158.82, moving back towards levels that were seen before reports of a “rate check” on 23 January. A firm US Dollar and higher US Treasury yields also added pressure on the Yen.

    Inflation Data And Market Focus

    US inflation data met expectations. CPI rose 0.3% month-on-month in February, up from 0.2% in January, while headline CPI held at 2.4% year-on-year. Core CPI rose 0.2% month-on-month, down from 0.3% in January, and the annual core rate stayed at 2.5%. Markets are now focused on the Personal Consumption Expenditures inflation report due on Friday. Expectations for central bank policy also shifted. A Reuters poll said the Bank of Japan is expected to keep its key rate at 0.75% on 19 March, and about 60% of economists see 1.00% by end-June. The International Energy Agency agreed to release about 400 million barrels of Oil from strategic reserves, with G7 support. Donald Trump said the war with Iran could end “soon” and that there is “practically nothing left to target.” We remember this time last year, in early 2025, when USD/JPY was pushing toward 159 as the market reacted to the US-Iran conflict. The combination of oil supply fears and a firm US dollar, driven by a cautious Federal Reserve, kept the yen under immense pressure. Japan’s heavy reliance on imported energy made the currency especially vulnerable to the crisis.

    Policy Divergence And Trading Implications

    The primary driver then, oil supply fears, has now largely faded since the conflict de-escalated in mid-2025 and the IEA’s coordinated reserve release stabilized the market. With WTI crude oil now trading around a stable $79 a barrel, compared to the peaks of over $110 we saw during the war, energy-driven inflation is no longer the main concern for Japan. This has removed a significant headwind that was weakening the yen. Looking back, US inflation in February 2025 was holding at 2.4%, which kept the Federal Reserve on a hawkish path for most of that year. Today, with the latest CPI figures showing inflation has cooled to 2.1%, the market is now pricing in potential Fed rate cuts later this year. This shift in monetary policy outlook is fundamentally different from the firm-dollar environment of early 2025. While the Bank of Japan did eventually raise its key rate to 1.00% as many expected last year, their cautious stance remains. This leaves a significant, though slightly narrower, interest rate differential that continues to influence currency flows. However, the momentum is now shifting away from further Fed tightening. Given that the geopolitical risk premium has vanished and the Fed’s next move is likely a cut, the explosive upward momentum we saw in USD/JPY has stalled. Traders should therefore consider strategies that benefit from range-bound trading or a gradual decline in the pair. Selling out-of-the-money call options on USD/JPY around the 152 level could be a viable strategy to capitalize on reduced volatility and capped upside potential.
