The 10-year U.S. Treasury yield reached 5.34% this week, its highest level since 2002, 24 years ago, when the dot-com bust was under way. Bond investors want a steeper price to lend to Washington. The 30-year Treasury yield has also surged to a more-than-two-decade high.
The Bond Market's Verdict
The 10-year yield had only recently touched its highest level since 2007. Now it has blown past that mark. Investors have sold bonds and demanded higher rates at government bond auctions as inflation climbs.
The logic is simple. Higher prices erode the value of investments over time, and bondholders want compensation for that loss. They're also watching higher gas and diesel prices, which have fed inflation worries. And they're pushing yields up because they expect the Federal Reserve to keep raising its target interest rates.
That expectation gained fresh support on Wednesday. The government released a stronger-than-expected report on gross domestic product, the broadest measure of U.S. economic activity. An inflation report showed prices rising well above the Fed's target. The Fed is expected to respond to both.
An Economy Running Hot
The economy appears to be overheating, while unemployment remains low. The September jobs report, due Friday, is forecast to show the jobless rate holding at 4.1%, a rate economists call "full employment." Consumer spending has stayed strong, fueled by a strong stock market.
Private investment is adding to demand. Annual spending on AI infrastructure is measured in the trillions of dollars. It's expected to keep growing over the decade and beyond, even as interest rates rise. Businesses, in other words, still commit capital despite higher borrowing costs.
Strong growth would normally be welcome news. But prices are rising well above the Fed's target, and that strength points toward further rate increases.
Debt Looms Over Both Parties
Inflation isn't the only worry weighing on the bond market. Debt concerns have also pushed yields higher. Government spending by both political parties has drawn criticism for putting the country on an unsustainable fiscal path.
The pressure reaches beyond the United States. Debt concerns and resurgent inflation linked to high oil and fuel prices have pushed rates higher around the world. On Thursday, the 30-year U.K. government bond yield reached 6% for the first time since 1998, 28 years ago.
Two major economies now face the same message from lenders. Investors want more in return for holding government debt, and they're asking at the same time that inflation is running hot.
Why This Matters:
Bond yields set the price governments pay to borrow, and that price is climbing. At 5.34%, the 10-year yield means every dollar of new federal debt, and every dollar of debt that must be refinanced, costs more to carry. From a fiscal perspective, the increase sharpens the question of how long both parties can keep spending as they have. Inflation compounds the problem: bondholders demand compensation for rising prices and expect more Fed rate increases. Meanwhile, low unemployment, strong consumer spending and trillions in AI infrastructure investment show strength in the private economy. The bond market is now pricing the risk that government borrowing and inflation could strain that growth. Friday's jobs report will show whether the labor market is as tight as forecast.
