Treasury yields hit 24-year highs as Fed, having just raised rates, readies its minutes

Long-term U.S. government borrowing costs climbed to their highest level in more than two decades on Wednesday, intensifying a bond-market selloff that has knocked stocks off last week's record highs and is now colliding with a Federal Reserve that, instead of cutting rates to calm markets, raised them a month ago. The Fed is due to release the minutes of that September meeting at 2 p.m. Wednesday, giving investors their first detailed look at the debate behind a decision that has left the central bank and the bond market pulling in different directions.

The 10-year Treasury yield, the benchmark that underpins mortgage rates and corporate borrowing costs, touched 5.34% this week, its highest level since April 2002, before easing slightly. The 30-year yield climbed as high as 5.70%, also a two-decade peak. Equities have wobbled in response: the industrial sector bore the brunt of Wednesday's selling, with Caterpillar shares down roughly 6%, Deere down about 4% and PACCAR off nearly 2%, as investors recalculated the cost of financing the heavy machinery those companies sell largely on credit.

The numbers

According to the Treasury Department's daily par yield curve data, the 10-year note closed Monday at 5.27% and the 30-year bond at 5.64%, both up roughly a full percentage point since the start of the year. The rise has been swift: the 10-year yield broke above its 2007 peak in the first days of October, then pushed through the 2002 level within a week, a climb that traders and economists have linked to persistent inflation, heavy government bond issuance and a surge in oil prices tied to the conflict with Iran.

The fiscal backdrop is stark. Total U.S. public debt outstanding stood at just over $40.2 trillion as of October 5, according to the Treasury's own debt-to-the-penny tracker — up from roughly $34 trillion two years ago and more than double what it was when the 10-year yield last traded this high. Debt held by the public alone now exceeds $32 trillion, a load that must be refinanced continually at whatever rate the market demands.

Compounding the pressure, the Fed did not cut rates into the turmoil. At its September 15-16 meeting, the Federal Open Market Committee raised its benchmark rate a quarter point, to a target range of 3.75% to 4.00%, citing inflation that remains elevated even as it acknowledged slowing job growth. It was an unusual combination: a central bank tightening short-term policy while long-term market yields were already rising on their own, a dynamic that has left short- and long-term borrowing costs climbing in tandem rather than offsetting one another.

How it got here

The immediate trigger for this week's leg up in yields was a familiar one repeated for months: heavy issuance of Treasury debt running into a market less willing to absorb it without being paid more. But economists have pointed to a second, newer force layered on top of the deficit story — the financing needs of the artificial-intelligence buildout, which is pulling enormous sums of corporate and government-adjacent capital into long-dated debt markets at the same time Washington is selling its own bonds. Economist Diane Swonk described the combination, in comments reported by 24/7 Wall St., as a "perfect storm" of government debt issuance and AI data-center capital needs arriving in the market simultaneously.

The oil market has added fuel of its own. Crude prices have risen on renewed fears over shipping disruptions tied to the Iran conflict and the Strait of Hormuz, feeding directly into the inflation numbers the Fed is trying to bring down — and giving bond investors one more reason to demand a higher premium for holding debt over longer horizons.

Treasury officials have tried to talk the market down. In late August the department expanded a buyback program for longer-dated bonds, intended to smooth trading and arrest the climb in yields; it has not worked. Treasury Secretary Scott Bessent, pressed on the bond market's defiance, dismissed the idea that the selloff amounted to a verdict on U.S. policy.

"I can't control the bond market. What I can do is try to get people to slow down," Bessent said, adding: "We are not seeing people sell treasuries to buy German bonds."

Separately, Fed Chair Kevin Warsh — confirmed by the Senate in May and now five months into leading the central bank through this stretch — has signaled to bank economists that further increases in long-term yields could themselves do some of the tightening work the Fed would otherwise have to do through additional rate hikes, according to a note from Goldman Sachs economist Mike Mitchell cited in market reports earlier this month. That framing has done little to settle markets already uneasy that a new, less predictable Fed chair is navigating the handoff from Jerome Powell at the same moment the bond market is in open revolt.

Who is affected

The clearest casualties this week have been capital-intensive industrial companies that sell equipment on credit or depend on customers financing big-ticket purchases. Caterpillar, Deere and PACCAR all fell sharply as the yield move accelerated Wednesday. Caterpillar, which trades at roughly 35 times trailing earnings and recently announced a $1 billion expansion of its compact-equipment manufacturing in North Carolina, fell hardest of the three. Farm, construction and trucking customers face a higher bar before committing to major capital purchases as rates on equipment loans and leases move with the long end of the curve.

The damage is not confined to one sector. Homebuyers face higher mortgage rates, which track the 10-year yield closely. The federal government itself pays more every time it rolls over maturing debt, adding to the deficits driving the selloff in a feedback loop that economists have flagged as a growing risk. And the broader stock market, which was setting records as recently as last week on optimism about AI-driven earnings, now has to defend historically rich valuations against a genuine alternative: a 30-year Treasury bond paying well over 5.6% with no credit risk.

• 10-year Treasury yield: 5.27% as of Monday's close, after touching 5.34% intraday — highest since April 2002
• 30-year Treasury yield: 5.64% as of Monday's close, after touching 5.70% — also a two-decade high
• Total U.S. public debt outstanding: just over $40.2 trillion as of October 5
• Federal funds target range: 3.75%-4.00%, raised a quarter point at the September FOMC meeting

What happens next

Wednesday afternoon's release of the September meeting minutes is the next real test of how markets interpret the Fed's thinking, particularly whether officials debated the rate hike as a one-off response to an inflation scare or the start of a longer tightening path layered on top of a bond market that is already tightening conditions on its own. The committee's next scheduled meeting is October 27-28, by which point several more weeks of Treasury auctions — and, potentially, further escalation or de-escalation around Iran — will have tested whether this week's yield levels mark a peak or a staging post to something higher.

For now, Bessent's Treasury has given no indication it will slow the pace of long-term bond issuance, even as it leans on jawboning and a modest buyback program to manage the market's reaction. Economists broadly agree that only a credible path toward narrowing the deficit, a cooling in inflation data, or both, would durably bring long-term yields down from their highest levels since the early Bush administration. Until one of those arrives, the companies and consumers whose borrowing costs move with the 10-year and 30-year Treasury are likely to keep absorbing the shock first.
