USD/JPY Holds Range Ahead of Japan CPI and Fed Decision

Key Moments

USD/JPY trades around 158.50 in Tuesday’s Asian session, supported by higher U.S. Treasury yields.
BoJ Governor Kazuo Ueda says underlying inflation is approaching the 2% target, while warning long-term yields could rise if policy lags.
Futures pricing via CME FedWatch shows 82.8% odds the Fed keeps rates unchanged this month and 93.6% odds of a hike in December.

Dollar-Yen Stable Ahead of Japan CPI Release

The USD/JPY pair is trading steadily near 158.50 during Asian hours on Tuesday, with market participants reluctant to take large positions before Japan’s National Consumer Price Index (CPI) data due on Friday. Firm U.S. Treasury yields are lending support to the U.S. Dollar (USD) against the Japanese Yen (JPY), helping to anchor the pair in a tight range.

Japan’s Prime Minister Sanae Takaichi rejected suggestions that she is to blame for the weak JPY and elevated interest rates. She said her administration aims to bolster confidence in the currency by fostering a stronger economy and indicated that issuance of Japanese government bonds will be managed carefully in the next fiscal year’s budget.

BoJ Signals Inflation Near Target, Warns on Yield Dynamics

Separately, Bank of Japan (BoJ) Governor Kazuo Ueda stated that underlying inflation is moving very close to the central bank’s 2% target. He also cautioned that long-term bond yields could climb if markets judge that the BoJ is not increasing its policy rate at an appropriate pace.

FXS Speechtracker scores the speech at 7/10, slightly below Ueda’s historical 7.4/10, but the emphasis on “underlying inflation near 2%” and a positive wages–prices loop marks a mildly hawkish tilt versus past caution. Ueda highlights demand-led inflation from robust global demand, domestic capex and tight labor markets, while warning that miscalibrated policy could push long-term JGB yields higher, signaling greater readiness to tolerate firmer rates as long as the 2% goal is credibly in sight.

At the same time, Ueda stresses no change in the fundamental bond taper approach and rejects preannouncing emergency JGB measures, framing any intervention as conditional on the speed of long-term rate moves and market stability. This combination of confidence in achieving the 2% target, acknowledgement of both supply- and demand-driven price pressures, and commitment to keep financial conditions accommodative supports a view that BoJ policy is gradually normalizing, which is modestly supportive for the Yen but constrained by a cautious approach to bond market operations.

Fed Expectations and U.S. Yield Backdrop

U.S. Treasury yields are edging higher as investors assess the Federal Reserve’s stance ahead of its policy meeting at the end of the month. According to the CME FedWatch tool, market pricing currently reflects an 82.8% probability that the Fed will leave interest rates unchanged this month, while the likelihood of a rate increase in December stands near 93.6%.

Japan CPI Outlook and BoJ Normalization Path

Analysts at Brown Brothers Harriman anticipate that Japan’s September CPI report on Friday will show a modest pickup in inflation. They project that “headline CPI … expected at 2.1% y/y vs. 1.9% in August, core CPI ex. fresh food … expected at 2.1% y/y vs. 1.7% in August, and core CPI ex. fresh food & energy CPI … expected at 2.3% y/y vs. 1.9% in August.”

However, they emphasize that the BoJ is “unlikely to crank up the pace of tightening” because headline CPI and core CPI excluding fresh food and energy are still “tracking below its 2026 projection of 2.5%.”

In interest rate markets, Brown Brothers Harriman notes that “the swaps curve price in less than 5% odds of a 25bps BoJ rate hike to 1.50% on October 30, and 80% probability of a hike on December 18,” highlighting expectations for a measured normalization trajectory. On this basis, the firm believes “that leaves USD/JPY likely to trade within a 155.00-160.00 range in the near term.”

Technical Picture: USD/JPY Held in a Capped Range

On the daily chart, USD/JPY maintains a bearish short-term tone as spot prices remain below the 100-day simple moving average (SMA). The pair is trading above the 20-day Bollinger middle band, while the 14-day Relative Strength Index (RSI) reads 56.69, indicating mild positive momentum that only partially counterbalances resistance from the prevailing downtrend.

On the upside, initial resistance is located at the 20-day Bollinger upper band near 158.92, followed by the 100-day SMA at 159.45, which acts as a more significant ceiling. On the downside, first support appears at the Bollinger middle band around 158.05, ahead of the lower Bollinger band near 157.20, where dip-buying interest could emerge to temper a deeper correction.
