## In brief

- The 10-year Treasury yield rose to 5.25%, its highest level since 2007; the 30-year hit 5.6%, highest since 2002
- Yields jumped Monday after Trump dismissed Iran’s offer to reopen the Strait of Hormuz; oil is near $100 a barrel
- Gross U.S. debt passed $40 trillion in August, or 124% of GDP, with deficits near 6% of GDP
- Higher Treasury yields feed directly into mortgage, auto and business borrowing costs across the U.S. economy

The yield on the 10-year U.S. Treasury note rose to 5.25 percent this week, its highest level in 19 years, as the war with Iran kept energy prices high and investors braced for the Federal Reserve to raise interest rates again.

Yields had not reached that level since 2007, just before the financial crisis. The 30-year yield climbed to 5.6 percent, the highest since 2002, and short-term yields rose as well.

Yields jumped again on Monday after President Trump dismissed Iran’s [cease-fire offer to reopen the Strait of Hormuz](https://rews.cc/a/iran-offers-us-a-seven-day-plan-to-reopen-the-strait-of-horm-8efb64), raising the risk that the conflict — and the energy crisis it set off — drags on. Oil is trading near $100 a barrel, and investors are betting that if crude stays at those levels, inflation will stay elevated longer. Gasoline is around $4.45 a gallon and diesel at $6.52, near the record hit last week.

The rise matters far beyond the bond market. Treasury yields are the reference for most fixed-rate lending in the United States: lenders take the matching yield and add a margin for risk. When yields climb, so do the rates households pay on mortgages, auto loans and other credit.

Fear of persistent inflation is only part of the explanation. “Another reason yields have risen is that the so-called safety premium is disappearing,” Hanno Lustig, a finance professor at Stanford University, told El País. “People no longer trust the safety of U.S. Treasuries as much as before, and many investors are increasingly worried about the country’s fiscal position.”

That position has deteriorated on paper. Gross federal debt passed $40 trillion in August, equal to 124 percent of gross domestic product — the highest level since at least World War II — with annual deficits approaching 6 percent of G.D.P., according to Treasury Department data cited by El País. The government spent $1.78 trillion more than it collected last year, and analysts say spending has risen with the war while tariff rollbacks and the tax cuts in the “One Big Beautiful Bill Act” have cut into revenue.

Vitor Constancio, the former vice president of the European Central Bank, called the rise in yields “a serious problem with significant effects on economic developments,” because it raises the government’s own interest bill and squeezes everything else in the budget.

The effects compound. Higher mortgage rates shrink what buyers can borrow for a given monthly payment, and homeowners holding cheaper loans stay put, which slows home sales and construction. For companies, new bonds, refinancing and variable-rate loans all get more expensive, and costly credit makes big building projects — data centers, energy infrastructure, industrial expansion — less attractive. That is a particular concern for the tech sector, which is issuing record amounts of debt to finance artificial intelligence projects.

For now, investors are holding two views at once: optimism about the global economy, fueled by AI investment, and unease about inflation and the Fed’s next move. Bond prices and yields move in opposite directions, so when the market expects rates to stay higher, older bonds lose value and sellers must offer better returns. “Investors demand higher yields when they believe inflation will erode the purchasing power of future interest payments,” said Seth Carlos, an analyst at JP Morgan.
