Treasury curve flattens after the hawkish Fed as the 10-year fights the 5% line

The Treasury curve flattened after the hawkish meeting¹. At settlement the 2-year yield was 5.2 basis points higher at 4.723%, the 3-year 3.5 basis points higher at 4.807%, and the 5-year 2.5 basis points higher at 4.862%¹. Reuters recorded the same session as a sharp rise in the dollar, a slump in the Dow and the S&P 500, and a significant flattening of the bond curve².

Where the 10-year actually sits is disputed. One report had the 10-year yield surpassing 5% and described it as a market warning³; another had 10-year yields falling back below 5.00% in the same period⁶. A third view is that the 10-year is likely to get above 5% and stay there⁴. A more cautious reading simply has bond yields pressing toward 5%¹². In Asian trade the gap between two benchmarks narrowed to about 44.3 basis points from 49.4 basis points at Wednesday’s close¹¹.

Why it matters to investors

A flattening driven by the front end is the market repricing policy, not growth. Since March 2 the 2-year has risen by more than 130 basis points, which one analysis reads as the market pricing a Fed that may have to hike four more times¹⁰. Standard Chartered called the curve move mild and noted the S&P500 index fell 0.5% on the day, while arguing the hike built credibility and that one more looks likely in December⁵.

The long end is where the institutional fight is. Federal Reserve Chairman Kevin Warsh and Treasury Secretary Scott Bessent are at odds over how to manage the benchmark 10-year yield⁸. The rise in yields prompted Bessent to announce expanded buybacks of long-dated government debt⁹, and the Treasury’s promise to keep buying back long bonds is itself part of why the curve flattened⁷.

What to watch

Two things decide the next leg. The first is whether the buyback programme is large enough to hold the long end while the Fed pushes the front end higher; one market view is that the hike simply made Bessent’s job of shuffling the curve more expensive⁴.

The second is whether high yields are now structural rather than cyclical. Bloomberg’s framing is that elevated yields on Treasury bonds and government debt look like the new normal⁹. If that holds, the flattening is not a signal about the next recession so much as a signal about who is willing to fund the deficit, and at what price³.
