Rising Yields Raise Borrowing Costs Across Global Economy

Interest rates on government bonds are rising again around the world, making borrowing more expensive for consumers and businesses and heightening concerns about whether governments are issuing more debt than financial markets can handle.

Rising bond yields are one of the few forces in the world strong enough to get politicians to snap to attention. They can also have a big impact on Americans’ personal finances and on the broader economy.

The bond market can dictate how much ordinary people have to pay on their mortgages and car loans, as well as how much they earn from their savings accounts and 401(k) plans.

Fighting has flared up again in the Middle East, causing oil prices to jump and renewing inflation worries.

Investors typically demand higher interest rates, or yields, on government bonds when inflation is high or they think it may get worse.

On Tuesday, the yield on the 10-year Treasury, which strongly influences mortgage rates, reached 4.80%, the highest since early 2025. The 5-year Treasury, which is a benchmark for auto loans, touched its highest level since October 2025 at 4.55%.

Here’s a look at what’s going on and how it affects everyone: In addition to inflation concerns, several other factors are also pushing bond yields higher: Annual U.S. government budget deficits remain higher than they were before the pandemic, forcing the government to borrow more to pay all its bills.

Large tech firms are also borrowing heavily to build out the data centers powering AI.

And last Friday, Federal Reserve Chair Kevin Warsh signaled that the central bank may still have to lift its short-term rate in the coming months if inflation stays stubbornly elevated.

Rising yields have caught the attention of policymakers around the world, including Treasury Secretary Scott Bessent, who last month announced an unusual intervention in the bond market to restrain rising yields.

Robin Brooks, a senior fellow at the Brookings Institute, said Bessent’s moves and Warsh’s promise to corral inflation have likely kept longer-term rates lower than they would otherwise be and betray a rising concern about where yields are headed.

“You should care because this stuff under the surface is really bubbling,” Brooks said. “And you can tell it is because policymakers are starting to get pretty agitated.”

Yet Bessent downplayed the overall rise in U.S. yields in a conversation Tuesday with Fox Business host Larry Kudlow on the sidelines of the G20 finance ministers’ meeting in Asheville, N.C.

“I don’t think we are in any kind of a dire situation,” Bessent said. He argued that other countries’ bonds have seen bigger yield increases.

When governments and big companies borrow money, they don’t ask a bank for a loan. Instead, they sell IOUs to investors and promise to repay the money with a certain interest rate. If those IOUs are set to be repaid many years from now, they’re called bonds.

(IOUs the U.S. government will repay more quickly — within a few months or a few years — are called bills or notes.) Investors in the bond market often buy and sell these bonds after they’re issued, and they continue to pay the same interest rate.

But if the bond starts to look less attractive, a buyer can get bonds that were earlier worth $100 for less than that.
