WASHINGTON (AP) 鈥� The world is getting more uptight about lending money to President government 鈥� causing to climb in ways that are , and creating a in November鈥檚 midterm elections.
The energy price spike triggered by the Iran war has seeped into the that help fund the U.S. government. Interest rates on a 10-year U.S. Treasury note are topping 4.44%, up from 3.95% before the war started at the end of February. Average have climbed to their highest levels in nine months, while auto sales are slumping.
The challenge is global in scale, as interest rates have risen for multiple countries as the world has been adjusting to the prospect of higher inflation, mounting questions about the sustainability of government debt and a dramatic surge in .
Trump has tried to assure Americans that he has a plan to trim the roughly $1.8 trillion annual budget deficit. In the past, he has pointed to , payments from foreigners for his visa, spending cuts made by the , and faster economic growth. Last week, he said the led by Vice President JD Vance would be the key to unlocking massive savings.
鈥淚f he does really great, we鈥檒l have a balanced budget without having to do anything,鈥� Trump said.
Economists say this is probably unrealistic
Economists say Trump鈥檚 strategies to meaningfully curb the deficit are unlikely to deliver the promised results.
The cost of servicing the has tripled since 2021 to more than $1 trillion annually, said Jessica Riedl, a budget and tax fellow at the Brookings Institution.
鈥淧resident Trump signed a that will likely add $5 trillion to 10-year deficits 鈥� and tariffs are offsetting only a small fraction of those costs,鈥� she said. 鈥淏udget deficits are still projected to soar past $4 trillion annually within a decade under current policies.鈥�
Deficits are expected to grow over the next decade as the costs of outstrip tax revenues.
The 10-year U.S. Treasury rate climbed as high as 4.67% in the middle of May and has since eased as continued 鈥� just as rates initially climbed in 2025 because of Trump’s and then began to decline once Trump backed off the most extreme increases.
When Kent Smetters, faculty director of the Penn Wharton Budget Model, broke down the math tied to rising 30-year Treasury yields, he estimated that 60% of the increase had come from the expectation that America will continue its outsized borrowing and the other 40% was tied to the inflation driven by the Iran war and Trump鈥檚 tariffs.
Glenn Hubbard, a former chairman of the White House Council of Economic Advisers during the George W. Bush administration, worries that the U.S. may no longer have the same borrowing capacity as before to effectively combat an economic crisis, such as the or the .
鈥淚 don鈥檛 think we have the space that we had in 2008 or 2020 to deal with it,鈥� said Hubbard, now a professor at Columbia University’s Business School. 鈥淲ashington doesn鈥檛 seem to be full of ideas 鈥� good or bad 鈥� to solve it.鈥�
Interest rates are a concern for voters
Higher interest rates are giving Democratic candidates in the another line of attack at a time when about .
In Colorado鈥檚 fifth congressional district, Democrat Jessica Killin is leaning into the message that the persistent deficits and higher interest rates make it harder to buy or renovate a home, afford a new car or manage credit card debt.
鈥淭hings are already expensive,鈥� said Killin, an Army veteran who was a top aide to , the former second gentleman. 鈥淲e can already talk about gas, but the cost of borrowing only makes that worse.鈥�
Joe Reagan, an Army veteran also seeking the Democratic nomination, said in an email that he is talking 鈥渁 lot about fiscal stewardship鈥� in his campaign. 鈥淓very dollar spent paying interest is a dollar that isn鈥檛 being invested in infrastructure, education, veterans鈥� services, or economic growth,” he said.
They are challenging Republican Rep. Jeff Crank in a district that their party views as a potential pickup. Killin said the deficit is an example of how 鈥淭rump says one thing and does the opposite.鈥�
In his March 2025 address to Congress, Trump declared that 鈥渋n the near future, I want to do what has not been done in 24 years: balance the federal budget. We鈥檙e going to balance it.鈥�
Crank, the Republican incumbent, did not reply to requests for comment.
Cutting fraud is the new deficit strategy
The administration maintains that it is going to steadily reduce . As a share of the overall economy, the deficit last year was lower than it was in 2024, though that drop depended in part on tariff revenues that are subject to refunds after the Supreme Court ruled them to be illegal.
Treasury Secretary Scott Bessent last week cited a report showing that there was as much as $500 billion annually in fraudulent government spending that could be eliminated, 鈥渟o that would reduce the deficit substantially.鈥�
Bessent appeared to draw that conclusion from a that estimated there had been between $233 billion to $521 billion each year in fraudulent spending. But those numbers were drawn in part from the pandemic era when the government borrowed heavily to stabilize the economy.
The White House and Treasury did not respond to questions about the source of Bessent鈥檚 claims.
On deficits, Bessent told reporters at the White House that the administration was essentially dealt a bad hand from former President Joe Biden, a Democrat. 鈥淲e inherited the worst budget deficit in history 鈥� in history 鈥� when we were not in a recession or not at war,鈥� Bessent said.
Bessent had previously announced that the administration would aim to reduce the annual deficit to 3% of overall U.S. gross domestic product. It鈥檚 roughly double that percentage currently and Bessent did not directly answer a question about the timeline for hitting his target.
As of now, investors continue to buy shares in U.S. companies, causing the in a sign of confidence in America鈥檚 economic potential. But the increase in interest rates also suggests that investors view the national debt as a vulnerability for the U.S.
The financial markets might be able to inflict enough pain with higher rates in order to compel political leaders to address the systemic imbalances. Multiple economists said they expected that markets would force the deficit issue before voters would.
Hubbard emphasized that the whole bond market system rests on the trust that the debt will be repaid. He noted that the word 鈥渃redit鈥� is linked to a Latin term that is also the root of the word creed about a system of beliefs.
鈥淭hat is what debt is about: I believe you will pay me back,鈥� Hubbard said. 鈥淭hat works until it doesn鈥檛.鈥�
