Today's 2-Year auction graded an F on the eve of FOMC — a front-end that's supposed to be the safest parking lot in the world just got rejected, which tells you the market doesn't trust the Fed's path at any price being offered. Layer on managed money sitting at a historic short extreme in both the Euro and the Yen, meaning dollar longs are extraordinarily crowded into a meeting where one dovish syllable unwinds that trade violently. Five of six AC pillars are reading bearish simultaneously — liquidity, Fed, smart money, macro, and sentiment — with markets the lone holdout at neutral. If tomorrow's statement carries any softness on the rate path, the dollar unwind plus a failed short-end auction creates a very ugly feedback loop for anyone positioned for stability.
