AI Summary. U.S. Treasury yields have surged to multi-decade highs across maturities, with the 30-year yield reaching levels not seen since 2007 and the 10-year approaching 5%. Rising oil prices are driving inflation expectations, pushing markets to price in near-certain Federal Reserve rate hikes within months.
Core argument: The 30-year Treasury yield reached its highest level since 2007 and the 10-year hit 4.93%, its highest since November 2023, as an oil-driven inflation surge pushed traders to price a Fed rate hike at 70% odds for next week.
Yields on US government debt rose to fresh multiyear highs — stoking demand for an auction of 30-year bonds. Treasury yields rose by five to 12 basis points across maturities, with the 30-year benchmark reaching levels last seen in 2007. The selloff lured investors to a $22 billion auction of 30-year bonds, which drew historically strong demand. The new securities were awarded at 5.308%, nearly three basis points lower than their yield in pre-auction trading just before the bidding deadline, meaning that bidders at higher yield levels missed out. Investor demand was so strong that a record low 2.2% of the sale went to Wall Street dealers. The auction’s 5.308% result was 2.7 basis points lower than the market level going in, the second-biggest negative gap on record in the past five years.AI Summary. The U.S. 10-year term premium has held flat over the past year and remains below those of Japan and Germany, indicating markets are not pricing in deteriorating U.S. fiscal credibility. Higher long-term rates reflect a shift in Federal Reserve rate expectations toward hikes rather than cuts, not fiscal stress.
Core argument: The New York Fed’s 10-year term premium has moved sideways over the past 12 months, indicating that rising long rates reflect shifting Fed rate expectations rather than deteriorating market confidence in U.S. fiscal sustainability.
The New York Fed’s measure of the US 10-year term premium has moved sideways over the past 12 months. On this measure, there has been no deterioration over the past year in how the market prices US fiscal sustainability or Fed credibility. The US term premium currently sits below the term premiums of Japan and Germany. This suggests that the market is less worried about the US fiscal situation compared with the fiscal situation in Germany and Japan. Put differently, the Fed went into 2026 expecting several cuts, and now the FOMC is leaning toward hiking. With this backdrop, it is not surprising that long rates are higher.AI Summary. A Treasury buyback program that briefly suppressed long-term government borrowing costs has been fully reversed by renewed global bond selling, with 30-year yields back at 5.27% and 10-year yields ~10 basis points higher than before the intervention.
Core argument: The 30-year Treasury yield has returned to 5.27% and the 10-year yield sits ~4.8% — more than 10 bps above pre-intervention levels — fully erasing the gains Bessent’s August 19 buyback expansion briefly secured.
The yields on the longest-dated US government bonds shot back to levels seen just before Scott Bessent shocked markets last month by expanding a buyback program in an effort to halt the rise. The gambit worked briefly, until the selloff that’s been sweeping through global markets pushed the government’s borrowing costs up again. By Tuesday, that drove 30-year Treasury yields to 5.27%, the level seen moments before Bessent announced the move on August 19. The 10-year yield — a crucial benchmark for the cost of all types of loans — is more than 10 basis points higher than it was then, at roughly 4.8%.AI Summary. 54 percentage point yield increase since 2022. The shift reflects reduced Federal Reserve absorption of long-duration debt, forcing private investors to demand greater compensation for interest rate risk.
Core argument: Term premium accounts for 1.56 percentage points — nearly two-thirds — of the 2.54-point rise in the 10-year Treasury yield since March 2022, dwarfing the 98-basis-point contribution from rising expected short rates.
I plot a decomposition of the increase in the 10-year yield into a term premium component and a future short rate component. According to this measure, a big chunk —1.56 pps (or nearly 2/3 rds)— of the 2.54 pps increase in the 10-year yield since March 2022 is actually due to an increase in the term premium. That premium (the red line in the figure) turned negative around 2015, and [when] it bottomed out in 2020, yields (black line) were trading 135 bps below the path of future short rates (blue line). That’s not entirely surprising: The Fed was absorbing a large share of Treasury issuance at the long end of the yield curve —as well as MBS issuance— effectively removing a great deal of interest rate risk from the market.AI Summary. The 10-year Treasury yield has risen above 4.75% as higher oil prices reinforce expectations of Federal Reserve rate hikes. The 30-year yield also climbed to near 5.26%, though Treasury buybacks in that sector have kept it below recent multiyear highs.
Core argument: The U.S. 10-year Treasury yield surpassed 4.75%—its highest since January 2025—as rising oil prices reinforced market expectations of further Federal Reserve rate hikes.
The US 10-year yield topped 4.75% for the first time since January 2025 as rising oil prices bolstered expectations that the Federal Reserve will hike interest rates. While 30-year yields also climbed Monday, rising five basis points to near 5.26%, they remained well below their mid-August multiyear highs, having retreated after the Treasury Department said earlier this month it would increase its buybacks of debt in the sector to bolster its market value.AI Summary. Long-term interest rates are now driven by inflation data, labor market surprises, Treasury supply, and rising term premium rather than Federal Reserve meeting announcements. This shift occurred because rate hikes were fully priced before each meeting, leaving non-calendar macro data as the primary mover of the 10-year Treasury yield.
Core argument: The 10-year Treasury yield’s roughly four-percentage-point rise since 2022 occurred almost entirely outside Fed meeting days, marking a structural break from the prior 30-year pattern in which long rates moved almost exclusively on FOMC announcements.
For 30 years, the 10-year Treasury yield fell almost entirely on the handful of days around Fed meetings, and did essentially nothing the rest of the time. That stopped in 2022 after the Fed began to raise interest rates. The 10-year has since risen roughly four percentage points, but almost none of that came on Fed days. The reason is that each hike was largely priced by the time the Committee met, so the FOMC announcement and press conference carried little news for the long end, and the move higher instead came from higher-than-expected CPI prints, stronger payrolls, increasing Treasury supply and a rising term premium, none of which sit on the FOMC calendar.AI Summary. Rising long-term bond yields reflect higher expected short-term interest rates over the next decade, not concerns about government debt sustainability, as both inflation expectations and the risk premium for holding long-term bonds have remained stable.

Core argument: The rise in ten-year real Treasury yields is driven almost entirely by higher expected long-run overnight rates, not by fiscal credibility concerns or debt sustainability fears.
Ten-year real yields are equal to the average expected overnight yield over the next ten years, plus a risk premium that investors demand for locking up their money for ten years. This term premium reflects the fact that realised overnight rates might deviate from expected overnight rates. If the market saw fiscal credibility or debt sustainability problems, this would show up in an increased term premium. But the term premium has also been stable and is only a hair lower since the end of last year. With term premium and inflation expectations contained, the recent increase in bond yields is therefore almost entirely due to higher expected overnight rates over the long term.
