USD/JPY Nears 40-Year Low as Fed Hike Bets Keep Dollar in Control

Quick Take

USD/JPY is still being driven by the dollar, not by yen strength. The U.S. dollar has climbed to a 13-month high as markets price a more hawkish Fed path and investors look for safe-haven assets after a global tech-led stock selloff. Reuters reported that the dollar index reached 101.44, while the yen weakened to around 161.57 per dollar, near levels that keep intervention risk active.

Why the Dollar Still Controls USD/JPY

The main support comes from Fed repricing. Markets are now assigning a 37% probability of a 25-basis-point Fed hike in July and around 70% probability for September, according to Reuters. That gives the dollar strong rate support, especially against the yen, where Japan’s policy rate is still much lower even after the latest BOJ hike.

This matters because USD/JPY is highly sensitive to rate differentials. When traders believe the Fed may tighten further while Japan normalises more slowly, the dollar-yen spread remains wide enough to keep buying pressure under the pair.

Risk-Off Flows Are Also Helping the Dollar

The dollar is also benefiting from defensive demand. Reuters reported that Asian markets were volatile after a sharp global selloff in technology and semiconductor shares, with the Nasdaq down 2.2% and broader market swings raising concerns about instability. In that kind of environment, the dollar often attracts demand as a liquid safe-haven currency.

For USD/JPY, this is a difficult mix for yen bulls. Risk aversion can sometimes help the yen, but if the stress is also pushing investors into U.S. dollars and U.S. bonds, the dollar can remain dominant.

Why the Yen Still Cannot Recover

The yen has not recovered strongly even after the BOJ raised rates to 1.0%, the highest level in 31 years. Reuters reported that some BOJ policymakers are already calling for faster rate hikes, with discussions focused on moving rates closer to Japan’s estimated neutral level.

The issue is that BOJ normalisation is still gradual compared with the Fed story. Reuters also reported that former BOJ policymaker Sayuri Shirai warned the yen could weaken toward 165 per dollar if the Fed raises rates again, because U.S.-Japan rate differentials would remain a major pressure point.

Intervention Risk Is the Main Limit

The main reason USD/JPY is no longer an easy long trade is intervention risk. Reuters reported that the yen was near 161.60 per dollar on 23 June, close to its weakest level in four decades, and that markets were watching for possible intervention after discussions between Japan’s finance minister and the U.S. Treasury secretary.

This matters because intervention risk can hit suddenly. Even if Tokyo cannot reverse the trend permanently, official action or stronger verbal warnings can trigger sharp short-term pullbacks, especially when speculative yen shorts are crowded.

Near-Term View

My near-term view is that USD/JPY can remain supported while Fed hike expectations stay high and the dollar keeps its safe-haven bid. However, the pair is now trading in a politically sensitive zone, so the risk-reward of chasing upside is becoming worse.

A sustained break higher would likely need stronger U.S. yields, no immediate pushback from Tokyo, and BOJ guidance that remains gradual. A sharp pullback could happen if Japan strengthens its intervention language, the BOJ signals faster tightening, or U.S. rate-hike pricing cools.

Conclusion

The main point is simple: USD/JPY still has strong dollar-side support, but the yen side is no longer passive. Fed hike bets and risk-off dollar demand are keeping the pair high, while BOJ rate discussions and Japan’s intervention risk make high-level rallies more fragile.
