USD/JPY Tests 154 as $105 Oil and Fed Risks Put 155.20 in Focus

Key Points

• USD/JPY remains near 154 after rebounding from a seven-month low around 152.9.
• U.S. producer prices rose 5.4% annually in August, strengthening expectations for another Federal Reserve rate increase.
• Brent near $105 creates an economic headwind for energy-importing Japan, while 155.20 has become the key technical resistance.

USD/JPY is struggling to extend its rebound above 154.00 on Friday, leaving the dollar roughly 1.4% lower against the yen for the week. The pair recovered after briefly falling below 153 earlier in the week, but stronger U.S. inflation expectations have not been enough to restore the previous uptrend. Traders now face conflicting forces: rising Treasury yields favor the dollar, while expectations for tighter Bank of Japan policy support the yen. Oil above $100 adds another complication for Japan before U.S. consumer inflation data.

Hot PPI Gives Dollar Fresh Support

The U.S. Dollar recovered Thursday after official inflation data showed producer prices accelerating faster than markets wanted to see. The U.S. Bureau of Labor Statistics reported that the Producer Price Index increased 0.4% in August, following a 0.1% increase in July. Producer prices were 5.4% higher from a year earlier.

Energy was a major driver. Final-demand energy prices increased 4.2% during August, while diesel fuel prices surged 24.1%. Those numbers reinforce concerns that the Middle East energy shock is feeding through to U.S. inflation.

That matters directly for the Federal Reserve. Markets have increased the probability of a 25-basis-point rate increase next week to roughly 70%, according to Reuters. The U.S. 10-year Treasury yield has simultaneously moved toward 5%, providing additional support for the dollar. The next test is Friday’s August Consumer Price Index, scheduled for 8:30 a.m. ET.

$105 Oil Complicates Japan’s Outlook

The yen has nevertheless maintained much of its recent advance. One reason is growing speculation that the Bank of Japan could tighten monetary policy again. Persistent Japanese wholesale inflation and recent yen strength have kept expectations of another BoJ rate increase alive.

Japan and the U.S. have also maintained close communication over foreign-exchange markets following their recent coordinated intervention. Japanese Finance Minister Satsuki Katayama said Friday that Tokyo’s position on currency-market stability remains unchanged. Oil, however, works against the yen through another channel.

Brent crude remained around $105 a barrel Friday after approaching $110, leaving the benchmark approximately 10% higher this week. Middle East supply disruptions and sharply reduced traffic through the Strait of Hormuz have driven the increase.

As a major energy importer, Japan is vulnerable to sustained increases in crude prices because they raise import costs and can weaken its trade position.

USD/JPY Faces 155.20 Resistance

Technically, USD/JPY remains in a weaker short-term structure despite its recovery from approximately 152.9. The important change occurred when the pair broke below 155.20, previously an important support region. That level now becomes resistance. UOB strategists similarly identify 155.20 as strong resistance, while maintaining a negative one-to-three-week outlook and highlighting 152.08 as important downside support.

A sustained recovery above 155.20 would weaken the immediate bearish case and bring 156.70–156.80 into focus. Above that, the 158 region becomes the next major hurdle.

On the downside, another rejection below 155.20 would leave 152.10 exposed. A decisive break beneath that area could extend the decline toward 150 and eventually the 149.50 region.

The larger bearish head-and-shoulders formation also deserves attention, but its projected target near 146.60 should be treated as a technical scenario rather than a forecast.

Conclusion

USD/JPY is caught between rising U.S. yields and strengthening Japanese monetary-policy expectations. Hot U.S. producer inflation is supporting the dollar, but the pair has yet to repair the technical damage created by its fall below 155.20.

Friday’s CPI report could settle the immediate contest. A stronger inflation reading would reinforce expectations for a Fed hike and could push USD/JPY back toward 155.20. Softer inflation would reduce that support and increase the risk of another test of 152.10.

For now, 155.20 is the decisive recovery level. Until the dollar closes convincingly above it, the rebound from 152.9 remains corrective rather than a confirmed reversal.
