EUR positioning has caught up to the dollar’s slide.
CFTC net longs in the euro have rebuilt from a 1-year low in March to an 18-month high. The easy carry on this side is gone.

Two months ago, speculative EUR longs were the cleanest squeeze trade in G10 FX. The latest CFTC Commitments of Traders report removed that setup. Large-speculator net longs in the euro have rebuilt from a one-year low in March to their highest reading since the autumn of 2024, and asset-manager longs are at a fifteen-month high. The rebuild has been fast. The risk now is symmetric.
What the position has done
On the March 17 report, EUR non-commercial net longs were near 21,000 contracts, well below the recent average and in the bottom decile of the trailing twelve-month range. By the May 19 release, the same bucket has rebuilt to multi-quarter highs. The asset-manager bucket, which moves more slowly than the leveraged-funds bucket, has done the same. When both buckets are extending in the same direction, the market is not just a few macro funds chasing the dollar. It is the crowd.
Why the rebuild was so fast
Three things lined up. First, the dollar's softening into and after the 28-29 April FOMC, which we covered in the data-not-dots piece. Second, a wide US-vs-G10 activity surprise gap that gave macro funds a clean fundamental anchor. Third, structural euro flows: a front-loaded weekly demand from EUR-funded carry book closures and the resumption of European reserve-manager rebalancing into the front end of EGB curves. The first did the bulk; the second and third explain why the rebuild was orderly rather than spiky.
What positioning at this level usually means
Crowded longs do two things. They make the next bad day worse, because forced unwinds amplify the move. They also make the next consolidation slower, because the new longs need time to be comfortable holding through a chop. The historical analogue is the 2017 EUR rebuild that ran into the September-October 2017 ECB re-pricing: a 4 percent give-back over two weeks, then a slower re-entry by structural buyers. We are not forecasting the same move. We are saying the trade is no longer where the easy carry sits.
What changes the read
Watch three things on the next two Fridays. First, the leveraged-funds vs asset-manager split: if leveraged funds keep adding while asset managers ease back, that is the late-cycle pattern we just described. Second, the 25-delta one-month risk reversal: it has stayed close to flat through the rebuild, which is unusual; a widening to favour EUR puts is the first option-side signal that the trade has crowded. Third, the cross-currency basis: a tightening in the 3-month EUR basis is the cleanest indicator of structural euro demand cooling.
