Japan CFTC data shows JPY non-commercial net positions moved to ¥-61.7K from ¥-102.1K.
The net position remains negative, but it is less negative than the previous reading.
Speculative Positioning Shifts
We are seeing a significant reduction in bearish bets against the Japanese Yen, with net short positions shrinking by nearly 40%. This is the most aggressive weekly shift in sentiment we have seen since the fourth quarter of 2025. This suggests that large speculators are rapidly closing out their positions that profit from a weaker yen.
This change comes as the Bank of Japan’s recent commentary has become more assertive about combating yen weakness, fueling speculation of further policy tightening. Japan’s latest core inflation data, released for April 2026, held firm at 2.7%, keeping pressure on the central bank to act. This is happening while recent US economic figures showed a slight cooling, reducing the dollar’s strength.
Looking at the charts, this sentiment shift aligns with USD/JPY failing to hold gains above the 165 level, a psychological area of resistance. We saw a similar pattern of speculators covering shorts in October of 2025 right before authorities stepped in with strong warnings. That event led to a sharp, albeit temporary, strengthening of the yen.
Implications For Derivative Traders
For derivative traders, this environment suggests that the risk of a sudden yen rally, or a “short squeeze,” has increased considerably. Therefore, holding short yen positions via futures or options is becoming much riskier. Buying JPY call options or USD/JPY put options with expirations in the coming weeks could be a calculated strategy to position for a potential policy surprise or intervention.
