USD/JPY Defies Gravity: Price Soars Even as Yield Spread Support Crumbles
On the daily chart, USD/JPY has experienced a dramatic multi-month rally, climbing from near 144.70 in early August 2024 to a peak above 159.10 in January 2026. However, the pair has recently shown significant weakness, falling sharply to trade near 152.80 by mid-February 2026. This decline represents a clear breakdown from its previous uptrend and suggests a potential shift in momentum.
This price action becomes even more notable when viewed alongside the key macroeconomic driver: the US-Japan 10-year yield spread. Historically, a widening spread (favoring the USD) supports a higher USD/JPY, but the long-term correlation is currently very weak at 0.05. The recent data highlights a major divergence.
While USD/JPY was making its historic climb towards 159, the yield spread was actually in a persistent *downtrend*, falling from approximately 3.08% to below 1.84%. This is a clear and prolonged divergence where the currency pair moved opposite its fundamental anchor. The recent sell-off in USD/JPY coincides with the yield spread continuing to grind lower, suggesting the pair may now be realigning with this underlying pressure.
For traders, this context is crucial. The recent breakdown in price, coupled with the enduring downtrend in the yield spread, indicates that macro forces may be reasserting themselves. Upcoming high-impact US data (like Core PCE and GDP) could cause volatility in Treasury yields, directly affecting the spread. Additionally, the constant underlying theme remains the Bank of Japan’s stance. Any official commentary or action regarding its yield curve control or negative rate policy will directly challenge this dynamic, as JPY strength has often been limited by the BoJ’s ultra-dovish posture. The current setup shows a pair that rallied despite poor fundamentals and is now correcting lower as those fundamentals continue to deteriorate.

COT Analysis
USD/JPY has maintained a broader uptrend on the daily chart, recently trading near multi-year highs. During this price ascent, the COT large traders’ net position ratio has been in a clear downtrend, showing a sustained divergence. This indicates that while the price has risen, large speculative traders have been progressively reducing their net long exposure.

USD/JPY has been in a clear downtrend on the daily chart, falling from near 158 to around 152. This price decline aligns with a notable shift in the COT Large vs Commercial Net Position, which has moved from positive to negative values. This indicates that commercial traders, who are often considered the “smart money,” have been building net long positions as the price fell, creating a divergence where sentiment is turning less bearish even as the price drops. For traders, this correlation suggests watching for potential stabilization, though the immediate technical trend remains down.

The USD/JPY has been trading in a broad range while the COT data shows a persistent and growing divergence. Asset managers have been building a net-short position against dealers for months, yet the price has shown resilience and recent upward movement. This suggests underlying buying pressure is currently offsetting the bearish positioning sentiment, though the widening negative spread indicates strengthening conviction for a lower exchange rate.
