The 10-year-minus-3-month Treasury spread is back above zero, and a chorus of strategists is calling normalisation. That reading misses the mechanism. Every major S&P 500 bear market since 1995 was preceded by an inversion, but the recession itself has typically arrived after the curve un-inverts and steepens. The dossier's central claim is narrow and operationalisable: watch the slope of the re-steepening, not the sign of the spread. A slow drift higher is benign. A sharp bull steepener — short rates collapsing — is the historical signature of the cycle turning.
That 16-basis-point cushion is the entire margin between the current regime and the territory that has preceded every U.S. recession since the 1950s. Liberty Street Economics, drawing on work by Richard Crump and Nikolay Gospodinov, makes the statistical point sharply: the term spread — the ten-year yield minus the one-year — has fallen below zero before every postwar recession and has rarely visited those levels without one following. Their rotated block bootstrap, which preserves the joint factor structure of yields across maturities, is designed precisely to quantify how much of the current signal is information and how much is sampling noise. The honest answer is: more uncertainty than the headline probability implies.
The normalisation case, and its weak point
The Compound takes the other side. In its framing, the current normalisation — short-end yields falling, long-end rising — reflects a return to a higher nominal growth and inflation regime rather than an imminent downturn. That view has internal support from Warren Pies, who reads forward S&P 500 sales growth of 18 percent over 24 months as consistent with roughly 6 percent annualised nominal GDP. The weak point is the speed of the long-end move. A bear steepener driven by term-premium repricing is not the same animal as a bull steepener driven by front-end cuts; the former is a growth-and-inflation story, the latter is a recession tell. The dossier's most candid concession is that long yields reaching 6 to 7 percent would itself become the problem, regardless of which steepener won.
A bear steepener is a regime change. A bull steepener is a recession. The market is currently running both tapes at once.
Sitting underneath both readings is a fiscal arithmetic that neither camp disputes. The IMF projects U.S. gross debt-to-GDP at or above 143.4 percent by 2030, a trajectory that structurally pressures the dollar and lifts the equilibrium term premium independent of the cycle. That matters for the curve debate because it raises the floor under long yields: even a clean recessionary bull steepener would now collide with a supply backdrop that keeps the 10-year stickier than in prior cycles. The dossier offers a single quantified recession call — Crump and Gospodinov's modified model puts the probability of an NBER recession within a year of April 2025 at 0.75 — and otherwise leans on direction without conviction numbers. Readers should treat the cluster as one-sided on fiscal trajectory and genuinely split on cyclical timing. The operational watch-items are narrow: the slope and composition of any further steepening, the 6 percent threshold on the 10-year, and whether front-end pricing begins to run ahead of the Fed.
