The recent decision by the Federal Reserve to maintain the target range at 3.50%–3.75% following a 10–2 vote positions US monetary policy distinctly above Japan’s near-zero rates, resulting in an immediate strengthening of the US Dollar and a firmer USD/JPY exchange rate. Two governors advocated for a 25 bp reduction, yet the majority highlighted “solid” economic growth, a labour market that has merely “stabilised” rather than deteriorated, and inflation that continues to be “somewhat elevated” despite advancements. The Dollar Index made a recovery toward 96.70 after recently hitting four-year lows, while USD/JPY approached the range of 153.9–154.5, increasing nearly 1% for the day as yields rose across the curve. US equities displayed mixed reactions, with the S&P 500 reaching a record intraday high near 7,002.28, the Nasdaq rising approximately 0.3%, and the Dow remaining almost unchanged. For USD/JPY, the situation is clear: as long as the Fed maintains its policy above the 3.50% threshold and does not signal a swift easing cycle, the rate differentials continue to support the dollar side of the pair. The competition for the Fed chair position has emerged as a significant factor influencing USD/JPY, with the growing support for Kevin Warsh altering the landscape of US policy risk in the currency markets. Warsh is not an unfamiliar figure; he served as a Fed governor during the crisis period from 2006 to 2011, and he has persistently raised concerns about an excessive dependence on an inflated balance sheet and extremely accommodative policy. That history positions him as the most hawkish among the remaining candidates, distinctly contrasting with individuals the market had evaluated as strongly in favor of cuts. The rise of his candidacy has prompted investors to reevaluate the “debasement” trade concerning the dollar and to reduce some of the premium associated with bearish USD positions. The recent price action in USD/JPY indicates that following a significant drop earlier this week, the pair has bounced back above the 154 level. This recovery is attributed to the likelihood of a more traditional, inflation-centric approach from the Fed chair, which diminishes the attractiveness of shorting the dollar amidst ongoing political uncertainty.
In addition to individual characteristics, the data environment presents challenges for those supporting the yen. US producer prices showed resilience, with the headline PPI increasing by 0.5% month-on-month, following a previous rise of 0.2%, and maintaining an annual rate of approximately 3.0%. Meanwhile, the core measure surged by 0.7% for the month and 3.3% year-on-year, indicating that upstream price pressures remain significant. Simultaneously, the US 2s10s curve experienced a brief steepening to levels reminiscent of early 2022, despite a decline in outright yields following the Warsh headlines. This unusual scenario indicates that markets are beginning to factor in a varied blend of growth and inflation risks, rather than anticipating a straightforward decline in rates. For USD/JPY, that matters: a steeper curve and persistent producer inflation suggest caution against a rapid near-term cutting cycle, especially given the division among Fed officials, with one prominent governor advocating for a 25 bp reduction while others emphasize the need for patience. The overall impact indicates that dollar funding continues to be costly compared to yen, and the route to significantly reduced US yields – which is essential for prolonged USD/JPY declines – has not yet been established. The data flow from Japan is subtly diminishing the prospects for accelerated normalization by the Bank of Japan in the USD/JPY context. The headline CPI in Tokyo has decelerated to approximately 1.5% year-on-year, down from 2.0% in the prior month. The core measure has retreated to around 2.0%, while the core-core indicator has softened to about 2.4%, all figures falling short of consensus expectations. This situation does not constitute a deflation shock; however, it is sufficient to temper the case for consecutive BoJ rate increases, particularly following a significant yen appreciation earlier in the month that has already reduced imported inflation.
December retail sales fell short of expectations, declining approximately 0.9% year-on-year rather than achieving the modest gain anticipated by economists, underscoring the weakness in domestic demand. The response from rate markets indicates a shift in expectations regarding BoJ tightening: the likelihood of a move in March has diminished, with April emerging as the earliest plausible timeframe for another increase. The widening policy gap for USD/JPY – with the Fed maintaining rates at 3.50%–3.75% and no imminent cuts, contrasted with a BoJ that has the luxury of patience – supports the rebound from the lows near 152 and encourages speculative capital to favor buying dollar dips. Kevin Warsh’s nomination holds significance as it reflects the dynamics between the White House and the central bank. Markets had anticipated a chair who would endorse ongoing political demands for significantly lower rates; instead, they are confronted with a candidate known for his history of opposing lenient policy. This approach mitigates the tail risk associated with a highly politicized Federal Reserve that may accept significantly higher inflation for the sake of immediate growth. Additionally, it directly challenges the narrative of “permanent dollar debasement” that previously supported yen strength. For USD/JPY, every incremental piece of US data – from JOLTS and ADP to ISM services and jobless claims – will now be viewed with a more nuanced perspective: traders must take into account that strong figures could potentially postpone cuts under a Warsh-led Fed instead of being dismissed outright. The recent shift clarifies the reason behind the pair’s rally, even in the face of producer inflation exceeding expectations and ongoing discussions among some policymakers regarding potential cuts. The market is adjusting its stance, anticipating a Federal Reserve that appears less dovish than what was implied in pricing just a week prior.
The interplay between domestic politics and bond markets in Japan establishes the limits of USD/JPY’s movement before concerns over intervention take precedence in the analysis. Earlier in the month, the long end of the JGB curve experienced a significant sell-off, compelling traders to factor in the risk of heightened BoJ tightening and an increase in expansionary fiscal policy amid a possible landslide victory for pro-stimulus leadership. In the past fortnight, the previous trend has significantly reversed: the 2s10s and 2s30s curves have once again flattened as market participants reevaluate the potential strength of the ruling party’s mandate and as the BoJ indicates its preparedness to purchase additional bonds to maintain market stability. The forthcoming 10- and 30-year auctions will assess demand; however, the immediate upward pressure on yields has diminished, thereby lessening one factor that bolstered the yen. The possibility of direct FX intervention remains a concern. Recent rate checks by the Ministry of Finance have driven USD/JPY down to approximately 152.10, marking a three-month low. This movement occurred prior to US officials clarifying that Washington would not participate in any yen-support operations. This clearly indicates that Japan is operating independently, which diminishes but does not completely remove the deterrent effect. As USD/JPY ascends past 154.45 towards 156.00–157.00, these levels coincide with areas where previous interventions or significant verbal interventions have taken place. This suggests that any further movement upward will heighten headline risk, despite the medium-term macroeconomic outlook continuing to support dollar strength.
The positioning in futures introduces an additional “insider” dimension to the narrative. The most recent CFTC data indicates that non-commercial traders continue to hold a net short position on the yen, with JPY non-commercial net positions currently at approximately –33.9K contracts, compared to about –44.8K previously. This conveys two insights simultaneously. The market continues to exhibit a structural bias against the yen, which reinforces USD/JPY during pullbacks as those with crowded short positions typically defend their profitable levels. Second, a significant reduction in aggressive bearish yen exposure has occurred, indicating that the sharp decline to 152.10 earlier in the week has eliminated weaker positions without completely altering the longer-term trend. Overlaying that with options activity and reported stop-loss clusters reveals a pattern characteristic of a market that has eliminated late sellers while core funds remain positioned for a stronger USD/JPY. If the pair continues to ascend toward 156.00–157.00, those same participants will be on the lookout for official Japanese selling; however, until that occurs, the prevailing trend appears to be upward rather than downward.
