The yen is struggling, and Tokyo’s warnings have diminished in impact. On Thursday, USD/JPY was observed trading around 161.7, attracting new bids towards 162.00 and approaching a 40-year peak, positioning the Japanese yen near its lowest point against the dollar since 1986. The pair has disregarded a consistent stream of verbal intervention from Japanese officials, increasing approximately 0.9% for the week and 1.9% for the month as a strengthening dollar and the persistent interest-rate disparity between Japan and the United States overshadowed all efforts to elevate the currency. The yen has now relinquished all the gains achieved on April 30, when Tokyo executed a record-sized intervention to bolster it, highlighting the stark reality of how ineffective the authorities have become in the face of fundamental forces. With the May PCE inflation report set to release on Thursday, the pair is positioned near multi-decade highs. The market is closely monitoring two key questions: will the data further bolster the dollar’s momentum, and will Tokyo finally take action?
The Thursday session highlighted the yen’s challenges. USD/JPY advanced toward 162.00 during European trading hours, nearing the 161.95 area that signifies 40-year peaks, as the pair disregarded potential intervention risks ahead of the US inflation report. The yen continued to struggle against a stronger dollar, as the significant gap between the Bank of Japan’s interest rates and those of major central banks exerted persistent pressure on the currency. The technical backdrop affirms the dollar’s supremacy. USD/JPY is currently positioned above its 50-day moving average at approximately 159.31 and its 200-day average around 157.75. This setup indicates a bullish trend, further supported by technical models that reveal a significant dominance of bullish signals. The pair has experienced an increase of approximately 11.6% over the past year, reflecting the yen’s ongoing weakness against a dollar supported by the highest interest rates in major economies. The level itself holds significant historical importance. USD/JPY first reached 161 in July 2024, a level not seen since 1986, and the return to that zone indicates the yen is testing the lows of a multi-decade range. The persistent movement towards 162, despite ongoing verbal interventions, highlights that the underlying factors influencing the pair—namely the rate differential and the carry trade—have significantly outweighed the attempts to manage them, resulting in the yen remaining close to its lowest level in forty years.
The main driver of the yen’s depreciation is the significant difference in interest rates. With the Bank of Japan’s policy rate at 1.00% following its recent hike and the Federal Reserve holding at 3.50% to 3.75%, the gap sits near 250 to 275 basis points, a spread that makes holding dollars far more rewarding than holding yen. The differential serves as the primary fundamental influence on USD/JPY, and its ongoing strength has maintained the pair at levels close to multi-decade peaks. The gap has defied expectations of compression. Through early 2026, the consensus anticipated a narrowing of the differential as the BoJ tightened and the Fed eased, a scenario that would have bolstered the yen. However, the Fed’s hawkish shift under Chair Kevin Warsh has disrupted that outlook. With the Fed now indicating possible hikes instead of cuts and September hike probabilities at approximately 68%, the US side of the differential has strengthened rather than weakened, maintaining a significant gap and placing pressure on the yen. The differential’s stickiness is the core issue facing the yen. Historically, each 100 basis points of compression has been associated with a movement of 5 to 8 yen in the pair. The absence of the anticipated compression has eliminated the crucial catalyst that yen bulls were relying on. As long as the Federal Reserve maintains interest rates significantly above the Bank of Japan’s 1.00% and continues to adopt a tightening stance, the disparity in rates will consistently benefit the dollar. Consequently, the yen will face challenges in achieving a sustained recovery, irrespective of Japan’s own efforts toward policy normalisation.
The carry trade serves as the primary speculative driver maintaining the elevated status of USD/JPY. The strategy is straightforward and lucrative: borrow yen at approximately 1%, invest in higher-yielding dollar assets like US Treasuries yielding around 4%, and retain the difference. At scale, hedge funds manage billions in these positions, and the ongoing yen selling they produce exerts continuous downward pressure on the currency that verbal interventions fail to counteract. The trade has continued to yield profits even in light of the BoJ’s interest rate increases. Despite the Bank of Japan increasing rates to 1.00%, the gap with the United States remained sufficiently broad, allowing the carry trade to remain profitable, and the market has continued to prefer short yen positions. The yen’s position as the leading funding currency for global carry strategies indicates that as long as the rate gap continues and volatility remains subdued, the ongoing structural selling pressure is likely to endure. The carry trade involves a concealed risk, nonetheless. When the trade unwinds, triggered by BoJ hikes, a risk-off event, or intervention, USD/JPY can drop 500 to 1,000 pips in days as leveraged positions are liquidated, reflecting the kind of violent reversal seen in prior episodes. The buildup of densely packed short-yen positions establishes a coiled-spring effect, where an abrupt change in sentiment or an effective intervention might trigger a swift unwinding. This scenario positions the carry trade as both the catalyst for the yen’s weakness and the potential driver for any sudden turnaround.
The yen’s weakness has been exacerbated by the overall strength of the dollar. The US Dollar Index has surged past 101 to its strongest level since May 2025, driven by the Fed’s hawkish pivot and the repricing of US rate expectations toward hikes. This dollar momentum has pressed USD/JPY toward multi-decade highs. The greenback’s advance reflects both its yield advantage and its haven appeal during periods of market uncertainty. The dollar’s strength has been widespread. The same forces elevating USD/JPY have driven the euro and the pound to multi-month lows, as the dollar strengthens across the board due to robust US economic data and a hawkish Federal Reserve. Safe-haven flows associated with equity-market volatility and geopolitical uncertainty have increased the demand for dollars, thereby reinforcing the upward pressure on USD/JPY. The dollar’s dominance places the yen in a particularly unfavourable position. Not only does the wide rate differential favour the dollar, but the greenback’s broad strength means USD/JPY faces upward pressure from both the yen-specific weakness and the dollar-specific strength. The combination has overwhelmed the BoJ’s policy normalisation and Tokyo’s verbal warnings. As long as the dollar holds above DXY 101 with the Fed leaning hawkish, the yen faces a formidable headwind that its own tightening cannot overcome.
