US Deficit Nears Record Levels as Debt Tops $40 Trillion Under Trump

WASHINGTON — October 19, 2026 

 The US government is facing mounting budget pressures as federal debt exceeds $40 trillion and borrowing costs rise, creating an economic challenge for President Donald Trump and Republicans ahead of congressional elections on November 3.

The country’s debt reached the $40 trillion milestone in August, while the federal government recorded a budget deficit of about $2 trillion for the fiscal year that ended on September 30, according to figures cited in the report. The deficit was 12% larger than the previous year’s and the biggest since the surge in federal spending during the COVID-19 pandemic.

Despite the growing debt burden, financial markets have not yet shown clear signs that investors view the United States as a significantly riskier borrower. Analysts say the additional return investors demand for holding longer-term US government bonds has not risen in a way that signals major concerns about the country’s credit standing.

However, economists warn that continued large deficits could leave the government more exposed to higher interest rates. The Trump administration has argued that stronger economic growth will help manage the debt, while also pointing to import tariffs as a way to ease pressure on federal finances.

The fiscal 2026 deficit was the third-largest on record, while interest payments on federal debt reached a record $1.36 trillion. Government spending exceeded revenue by an amount equivalent to about 6.2% of the economy, compared with an estimated 3% annual deficit that could be sustainable under typical economic growth, according to analysts cited in the report.

The government’s total debt includes obligations to federal accounts such as the Social Security Trust Fund. Debt held by Treasury bond investors stood at about $32 trillion, roughly comparable to the size of the US economy.

The ratio of government debt to gross domestic product has reached around 100%, a level last seen during the financing of World War II. Economists disagree over how concerning that ratio is and whether the country faces a specific point at which debt becomes unmanageable. They generally consider an outright US debt default highly unlikely, given its potential impact on global financial markets.

Still, some Federal Reserve officials have warned that the country could eventually face a difficult adjustment. The severity of such a situation would depend on economic growth and whether policymakers take steps to address the imbalance between government revenue and spending.

Higher borrowing costs are already affecting consumers. Rising global bond yields have pushed up financing costs across markets, while the US government must continue borrowing to cover annual deficits and refinance existing obligations. The competition for investment funds also includes corporations financing artificial intelligence projects and other countries seeking capital.

The interest rate on 30-year US mortgages recently reached 7.40%, according to Freddie Mac, well above the roughly 3% rates common during much of the 2010s. Higher mortgage rates can make home purchases more expensive and increase monthly payments for borrowers.

Trump’s trade tariffs, a central part of his economic policy, initially generated tens of billions of dollars in additional government revenue. But after the Supreme Court struck down many of the tariffs earlier this year, the government was required to pay $145 billion in refunds, reducing much of the financial benefit. The tariff revenue had represented only a small portion of the overall gap between federal spending and receipts.

Federal Reserve officials have also blamed import tariffs for contributing to recent inflation. The November elections could influence the future of the policy, as control of Congress affects lawmakers’ ability to oversee the administration and shape tax and trade decisions.

Treasury Secretary Scott Bessent has sought to contain borrowing costs, but yields on the 10-year Treasury note have continued to rise. Analysts say the combination of high debt, rising interest payments and more expensive borrowing could be difficult to resolve through economic growth alone.

The growing fiscal burden is emerging as a political issue ahead of the midterms, with polls showing that the cost of living remains a major concern for voters. Analysts and policy advocates have urged candidates to explain how they would put federal finances on a more sustainable path, though the long-term risks will depend on future economic conditions and government decisions.
