The Curve Doesn’t Lie
April 25, 2026
What the 2Y–10Y Flattening Is Really Telling Us
Last month’s note argued that the oil shock had crossed into macro territory that the barrel was no longer a regional story but an inflation, policy, and portfolio problem. March confirmed that thesis and added a layer of complexity the market did not fully anticipate. Both the 2-year and 10-year Treasury yields rose sharply (53bps & 53bps), but the manner in which they moved is where the real story lives. That asymmetry is not noise. It is the bond market pricing two different problems at the same time.
When the short end and the long end price different problems simultaneously, the curve shape itself becomes the signal.
The Front End: Inflation Fear in Control
The 2-year Treasury is a proxy for the Fed’s policy path over the next two years. As oil moved from roughly $67 per barrel at the start of March toward $101 by month-end, the market rapidly unwound its expectation that the Fed would ease in 2026. By late March, futures markets were pricing a greater-than 50% 1 probability of a rate hike before year-end the first time that threshold had been crossed in this cycle. The 2-year punching through the Federal Funds Rate for the first time since late 2023 was the clearest expression of that shift: the bond market has moved from pricing relief to pricing restraint.
The Long End: A Different Calculation
The 10-year yield tells a different story. Higher energy prices argue for higher long-run inflation and therefore higher yields. But the same shock raises the probability of demand destruction, softer growth, and ultimately lower rates over the medium term. Those two forces offset each other at the long end, producing a smaller net move. The TIPS market makes this decomposition visible: the 10-year breakeven inflation rate spiked to 2.58% 2 at the height of the selloff but has since pulled back to around 2.36%, while the 10-year real yield continued to grind higher. The long end is not particularly worried that inflation becomes structural. It is increasingly pricing a world where the shock is large enough to destroy the demand that would have sustained it. The breakeven rolling over while real yields rise is the market’s verdict that inflation solves itself not through Fed discipline, but through demand collapse.
What the Spread and Credit Are Saying
The 2-year vs 10-year curve spread compressed from around 57 basis points entering March to approximately 52 basis points by early April. That bear flattening both yields rising, the short end faster is the curve’s signature for a stagflationary setup: near-term inflation pressure alongside medium-term growth deterioration. The current environment is not 1974, and that word should not be used casually. But the regime being priced sticky inflation at the front, softening growth at the back, a Fed constrained from responding cleanly to either shares enough with historical precedent that the parallel deserves attention.
Credit spreads are corroborating the signal. The ICE BofA US High Yield OAS 3 has widened to roughly 317 basis points. High yield spreads do not widen primarily in response to inflation they widen when the market anticipates that revenues, not just margins, are at risk. A supply shock compresses margins. Demand destruction threatens the top line. That distinction matters for how you read the spread move.
The Portfolio Problem
February’s note observed that the usual diversification channels were working less cleanly. March extended that challenge. Government bonds did not rally into equity weakness because inflation kept yields under pressure. Credit did not hold because growth fears began to outweigh carry. There is no clean defensive trade in a stagflationary setup: duration carries inflation risk, equities face both margin compression and revenue risk, and commodities have already repriced. What the curve is telling you is not where to hide. It is that the market is still in the process of pricing a regime it has not fully resolved and that the margin for error, for the Fed, for corporate borrowers, and for portfolio construction, is narrower than it was at the start of the year.
The barrel drove the macro in February. In March, the curve confirmed the transmission. April will begin to answer whether demand destruction becomes the mechanism through which this episode resolves, or whether something else intervenes first.
