Yen Weakens to 157 as Divided BoJ Hike Mutes FX Rally

Key Moments

Yen Slips as Market Questions BoJ’s Hawkish Resolve

USD/JPY is edging higher toward 157.60 during early Asian trading on Wednesday, with the Japanese Yen (JPY) extending its decline. The move follows the Bank of Japan’s (BoJ) rate increase last week, which was not accompanied by explicit hawkish forward guidance, leaving markets cautious about the pace of any further tightening.

The pair has been gaining momentum as investors reassess the BoJ’s stance after the latest policy meeting. The preliminary US Purchasing Managers’ Index (PMI) data, scheduled for release later on Wednesday, is also on traders’ radar as a potential catalyst for additional moves in the Dollar-Yen cross.

BoJ’s Split Vote Raises Doubts Over Future Rate Path

At its meeting last week, the BoJ raised its policy rate by 25 basis points to 1.25%, the highest level since 1995. The decision, however, was not unanimous, passing with a 7-2 majority after board members Toichiro Asada and Ayano Sato dissented. Market participants interpret this division as a sign that subsequent hikes could face greater internal resistance, which is weighing on the JPY.

Responding to questions about the possibility of consecutive hikes or larger adjustments, BoJ Governor Kazuo Ueda stated that the central bank would not pre-commit to ruling out any specific policy options ahead of board meetings.

Chidu Narayanan, chief APAC strategist at Wells Fargo, commented on the BoJ communication, stating: “Ueda’s press conference showed snippets of hawkishness, but they were insufficient to support the market’s aggressively hawkish expectations.”

Intervention Watch: Authorities on Alert as Yen Weakens

Market participants remain highly attentive to any signs of official action to support the Yen. The Nikkei newspaper reported last week that Japanese authorities had undertaken rate checks. Such checks – during which officials request currency quotes from banks to assess conditions – are widely viewed by traders as a potential precursor to actual intervention.

Strategists See Longer-Term Support from BoJ’s Evolving Stance

Analysts at OCBC note that the BoJ’s “7-2 vote split in favour of a rate hike may remain a near-term headwind for the JPY,” suggesting that a divided board may limit the immediate positive impact on the currency. Nonetheless, they emphasize that “the more important takeaway is that the BoJ appears increasingly willing to tighten policy at a faster pace.”

According to their assessment, this shift in approach “should ease concerns that the BoJ is falling behind the curve,” and bolsters expectations that a more assertive policy trajectory will, over time, lend support to the Yen, even if short-term swings remain pronounced.

Fed Tone Turns More Hawkish, Bolstering Dollar

On the US side, Federal Reserve commentary has skewed more hawkish. Fed’s Collins delivered a sharper tightening bias, reflected in an FXS Speechtracker score of 8.1/10 versus a baseline of 6.6/10. This higher score highlights stronger conviction around recent policy decisions.

By endorsing last week’s rate hike and cautioning that the probability of inflation remaining “notably above 2%” has risen, Collins framed policy as focused on restoring price stability now that labor market conditions appear more balanced. The reference to a “somewhat more restrictive” federal funds rate indicates a preference for keeping policy tight for longer – typically supportive of the US Dollar and a headwind for risk-sensitive assets.

The FXS Fed Sentiment Index advanced by 0.53 points to 150.49, underscoring that Fed communication remains firmly in hawkish territory and well above the neutral 100 level. Together with the elevated Speechtracker reading, this suggests a growing consensus within Fed messaging around the need for restrictive settings to return inflation to target, a backdrop that continues to underpin the Dollar against lower-yielding currencies such as the JPY.

USD/JPY Technical Picture

From a technical standpoint, USD/JPY is trading within a broad consolidation band on the daily chart. The pair remains capped below the 100-day moving average (MA) while holding above the 20-day Bollinger simple moving average (SMA) midline, pointing to a rangebound phase between overhead trend resistance and near-term support.

The Relative Strength Index (RSI) stands at 53.01, signaling a mild bullish tilt without yet indicating stretched conditions.

On the upside, the first hurdle is the 100-day MA at 159.55; a break above this level could open the path toward the upper Bollinger band near 160.85. On the downside, initial support lies around the Bollinger SMA midline at 156.55, with a more substantial base at the lower Bollinger band near 152.25, where any more pronounced correction would likely pause.
