USD/JPY in Focus: Intervention Threats and Monetary Policy Divergence

On October 15, 2026, the USD/JPY pair is influenced by two major factors: the potential for Japanese intervention and market expectations regarding US Federal Reserve interest rates.

The primary fundamental element is the imminent threat of intervention by Japanese authorities in the forex market. Japan’s Finance Minister stated that Tokyo and Washington have maintained a united front since their collaborative intervention in July, and are prepared to act decisively again if needed. This remark was made as USD/JPY dipped after US inflation data was released, before starting to rebound. The market considers the 160.00 level as a critical threshold, so nearing it prompts automatic profit-taking and a strengthening of the yen.

Although US CPI increased to 3.7% in September, exceeding forecasts, the market does not anticipate an immediate rate hike at the October meeting. The likelihood of such an action is pegged at approximately 40% or lower, as Fed officials have emphasized that there is no urgency to act.

The Bank of Japan is against another rate hike during its October meeting. Concurrently, markets are factoring in a high probability of a rate hike in December, estimated at around 88-90%.

Japan’s hawkish rhetoric is limiting USD/JPY from surpassing 159.00, while subdued expectations for an October Fed rate hike are curbing further yen strength. Today’s attention is on the US PPI data, which could provide upward momentum for the pair.

Technical Analysis

On the four-hour chart, USD/JPY encountered resistance at 158.91 after forming an upward wave structure, leading to a corrective decline. The price retreated to the crucial level of 157.57, which previously served as the consolidation center and is now viewed as the primary support. The existing structure suggests conditions for an upward move to resume, contingent on this support holding.

Today, the correction near 157.57 is anticipated to conclude, paving the way for a new upward wave towards resistance at 158.28. A close above this level could lead to a retest of 158.91 and a subsequent move towards 160.06. The MACD indicator remains positive, but the contracting histogram indicates diminishing upward momentum, with further confirmation of a trend reversal still required.

The one-hour chart displays a downward correction following the pair’s reach of resistance at 158.91. The price has tested support at 157.57 and exhibits early signs of recovery. The primary scenario projects the formation of a local upward wave, with an initial target at 158.28.

The Stochastic oscillator has exited oversold territory, with its signal lines turning upward, bolstering the chances of short-term gains. However, consolidation below 157.57 would negate the main scenario and set the stage for a further decline towards support at 157.24 and subsequently 156.47. Until key support is breached, the focus remains on a resumption of the upward move towards 158.91, with potential for 160.06 in the next upward impulse.

Conclusion

USD/JPY continues to be influenced by two major forces: the threat of Japanese intervention, which limits gains near the 160.00 threshold, and Fed rate expectations, which restrict the yen’s upside potential. Even though US CPI came in stronger than expected, markets assign a probability of around 40% or less for an October Fed rate hike, while the BoJ is unlikely to hike rates in October, with markets anticipating a December move. Japan’s assertive intervention rhetoric is keeping the pair below 159.00, and today’s US PPI data could serve as the next catalyst. From a technical standpoint, the pair is testing key support at 157.57, with the primary expectation being the end of the correction followed by an upward move towards 158.28, 158.91, and possibly 160.06. A break below 157.57 would undermine the main bullish scenario, leading to a decline towards 157.24 and 156.47.
