The Japanese Yen has experienced a notable resurgence against the US Dollar, driven by a combination of technical momentum, positioning, and a significant unwind of carry trades. According to Societe Generale’s Kenneth Broux, USD/JPY has sharply pulled back, breaking below key graphical support at 155 and trading under its 200-day moving average of 158.40. The next resistance is identified at 156.25, with downside objectives at 152.00/151.60 and 149.50, suggesting further potential for Yen strength if the downward momentum persists [1].
DBS Group Research economist Philip Wee highlights that the Yen has become the best-performing currency in the US Dollar Index (DXY) in 2026, appreciating 1.5% year-to-date against the USD overnight. The USD/JPY pair has fallen below its end-2025 level of 156.70, and a major trendline break has increased downside risk for the pair. Wee attributes this shift to the late-July joint US-Japan intervention, which established a stronger official backstop against disorderly Yen depreciation, and to US Treasury Secretary Scott Bessent’s August 18 announcement to double buybacks of long-dated US Treasuries, which shifted fiscal deficit concerns from Tokyo to Washington [2].
Both sources emphasize that the current Yen rally is not a repeat of the extreme volatility episode seen in the summer of 2024, but is instead being driven by technical factors, momentum, and a broad-based weakening of the carry trade. Societe Generale notes that the recent correction in USD/JPY, nearly 7% since the start of August, is about half the size of the collapse witnessed during the 2024 intervention episode, which had triggered a spike in volatility and reinforced gold’s appeal as a diversification asset [1].
DBS further notes that the broadening of Yen gains beyond the USD is significant, as it undermines the carry trade that had previously weakened the Yen’s traditional haven status. The combination of official intervention, shifting fiscal narratives, and technical breaks has reinforced the Yen’s appeal as a safe-haven currency and increased the likelihood of further downside for USD/JPY [2].
CONCLUSION
The Japanese Yen’s sharp appreciation against the US Dollar is being fueled by technical momentum, carry trade unwinds, and supportive policy actions. Both Societe Generale and DBS highlight increased downside risk for USD/JPY, with the Yen’s haven status and broad-based gains signaling a high-impact shift in currency markets. Market participants are likely to remain alert to further technical breaks and policy developments that could extend the Yen’s rally.
