Could US Data and BOJ Policy Trigger a USD/JPY Range Breakout?

USD/JPY is trading almost flat as markets digest the Federal Reserve's interest rate decision and await Friday's Bank of Japan announcement.

Does Warsh's measured tone soften the Fed's rate hold?

The U.S. dollar has edged down against its major peers following the Federal Reserve's widely expected decision to keep interest rates at 3.75%–4%. Ahead of next week's midterm elections, markets had priced in a 90% probability of a hold. The vote was 10–2.

Describing growth as strong, the Fed raised its assessment of the U.S. economy. It also noted that price stability had been central to much of the discussion.

The outlook for next year's rate hikes became less clear, however, following remarks from Federal Reserve Chair Kevin Warsh. He suggested inflation might return to the 2% target without materially affecting growth, increasing unemployment or “throwing sand in the gears”. Traders consequently scaled back their expectations for monetary tightening next year slightly.

Markets had been seeking guidance on a December hike, but interpreted his remarks as less hawkish than anticipated. The CME FedWatch tool now puts the probability of a December hike at 81%, compared with 84% previously, indicating a modest dovish reassessment.

Closely linked to expectations for Fed rates, the 2-year Treasury yield has declined. The U.S. Dollar Index has slipped as well, though its broader bullish trend is still intact.

Could U.S. data undo the modest dovish shift after the Fed decision?

Next in focus is U.S. core PCE, the inflation measure preferred by the Fed. September's monthly increase is forecast at 0.3%, compared with 0.2% previously, while the annual rate is expected to reach 3.1% from 3% in August.

Forecasts also point to annualised U.S. Q3 GDP growth of 3.2%, against 2.2% in the preceding quarter, underscoring the economy's strength and continued expansion.

The market response to these releases could exceed the reaction to the Fed meeting. Robust figures and inflation above forecasts would bolster expectations for a more hawkish Federal Reserve. Its insistence on seeing more data before taking further decisions, however, could moderate those expectations.

If core PCE and GDP beat forecasts, the recent dovish reassessment of the Fed could unwind, pushing Treasury yields and the dollar higher. Weaker readings, by contrast, could strengthen expectations for a less hawkish policy trajectory and weigh on USD/JPY.

Will the BOJ give the yen support?

The Bank of Japan is the next policy focus as its two-day meeting ends on Friday. Having already increased rates by 50 basis points this year, it is expected to keep them at 1.25%.

Japan's inflation has moved closer to the central bank's 2% annual target, with core CPI reaching 2.1% year on year in September. Against this backdrop, the bank has indicated that further rate increases remain under consideration.

Higher energy and raw material costs have pushed up both PPI and consumer price inflation. There are now early indications that these pressures are spreading more widely across the economy.

Nevertheless, headwinds arising from the Middle East conflict leave some uncertainty around Japan's economic outlook. This could determine how forcefully the BOJ raises rates over the coming months.

Markets broadly anticipate that the BOJ will maintain a quarterly tightening pace of 25 basis points, delivering the next increase in December and a subsequent one in March.

For dollar bulls, the principal risk is a clearer indication of a December BOJ hike: this could reduce the U.S.–Japan interest-rate differential and bolster the yen. Separately, a move above 159 would sharpen concerns about Japanese intervention as USD/JPY nears 160.

USD/JPY – what does the technical outlook suggest?

USD/JPY has consolidated near the 250 EMA since rebounding from the 2026 low around 154.40. Resistance at 159 has limited gains, while the 157 support zone has largely contained declines. With the RSI in neutral territory, directional signals remain limited.

A break above 159 could follow strong U.S. figures alongside a slightly dovish tone from the BOJ. Clearing that level would put the 160 resistance zone in view, along with the possibility of intervention by Japanese authorities.

Conversely, a softer USD and a hawkish BoJ could drive the pair below the 157 support zone. That would bring 155 into focus, followed by the 2026 low at 153.
