Managed money is historically max-short the yen, euro, and Canadian dollar simultaneously — a crowded dollar-long that historically snaps hard when it unwinds — and today's 2-year Treasury auction graded an outright F, signaling the front end is struggling to find buyers even at a point on the curve the Fed theoretically anchors. Five of six AC pillars are flashing bearish with markets the lone holdout at neutral, which means price hasn't caught up to the structural deterioration yet. If dollar longs capitulate into a weak auction backdrop, the rates-dollar-risk asset feedback loop becomes the only trade that matters.
