The CFTC’s 22 September 2026 futures-only report showed a widening non-commercial net short in sterling and a smaller net long in yen versus the prior week. The figures are positions in reported futures contracts, not a complete map of global spot FX flows or a forecast for either currency.

These are futures-only positions in reportable CME contracts. The CFTC explains that COT reports break down each Tuesday’s open interest in markets meeting its trader-reporting thresholds. They are published weekly and classify positions; they do not disclose the identity or motives of individual traders. CFTC: Commitments of Traders reports and methodology
Crowded trades may be vulnerable, but a net position is not a target
A larger net short can indicate that the reporting category has more short than long contracts, while a shrinking net long means the long-minus-short balance narrowed. Neither change says that traders must buy or sell next. Positioning can persist, grow further or be offset by activity in other instruments.
The contrast between sterling and yen provides a snapshot of two futures markets, not a clean comparison of conviction across the whole FX market. Contract sizes, open interest, participant mixes and hedging needs differ. Commercial traders, non-reportable positions, options and OTC instruments are not captured by this one non-commercial futures balance.
Price can move against a crowded position for a long time before any unwind occurs. Macro releases, central-bank expectations, yield differentials and broader risk sentiment can outweigh positioning data. A weekly COT figure is best used as context alongside those drivers, not as a trigger by itself.
Track the series, denominator and report date together
Compare more than one weekly observation and, where useful, relate net positions to open interest. A change in the net balance can result from long positions, short positions or both; the components matter because the same net figure can arise from different gross exposures.
Confirm that each comparison uses the same report family and contract market. Futures-only and futures-and-options-combined reports are not interchangeable, and the CFTC’s data apply to the stated Tuesday position date, not the later publication date. CFTC: Commitments of Traders reports and methodology
Use spot prices, forward markets, yields and policy communication to test whether the positioning change is being validated by market fundamentals. The alternative is that the COT shift reflects hedging, contract roll activity or a short-term adjustment that has little lasting effect on currency direction.
