U.S. Federal Debt Breaks the $40 Trillion Record: What Are the Consequences?

U.S. federal liabilities have surpassed the $40 trillion mark for the first time. The new record has revived concerns about the sustainability of the American economy, financial markets, and the cost of borrowing for households and businesses. If the current pace does not change, experts estimate that the debt could reach $50 trillion within six years.

Data from the U.S. Treasury Department confirm that federal debt has reached a record level of $40 trillion. The figure was reached much earlier than projections made just a few years ago.

In May 2023, the U.S. Congressional Budget Office projected that this threshold would be crossed during fiscal year 2028. However, another $1 trillion was added to the debt in just the past five months.

“At the pace we have been following, we will reach $50 trillion in just six years. Less than 10 years ago, we were at $20 trillion,” said Michael Peterson, head of the Peter G. Peterson Foundation, an organization that monitors public finances.

Peterson warned that the rapid expansion of debt is threatening the economy and the future outlook of the United States.

The problem is compounded by the fact that the U.S. government continues to spend more than it collects in revenue. In the first 10 months of this fiscal year, the federal deficit reached approximately $1.8 trillion.

A significant factor is demographic change. Every day, around 10,000 members of the “Baby Boomer” generation retire, while increasing life expectancy puts additional pressure on Social Security and Medicare programs.

In recent decades, Congress has also approved measures that have cut taxes and increased spending. These include the 2017 Tax Cuts and Jobs Act, the Trump administration’s 2025 law, known as the One Big Beautiful Bill Act, as well as the economic support packages approved during the COVID-19 pandemic.

These policies are expected to add trillions of dollars to the federal debt in the years ahead.

Another concern is interest payments, which are expected to exceed $1 trillion this year, setting a new record. For a long time, low rates allowed the U.S. government to finance itself at relatively little cost, but this changed after the Federal Reserve began raising rates to fight inflation following the pandemic.

Interest spending has more than tripled over the past five years and is now nearly equal to funding for Medicare. After Social Security, it represents one of the largest items in the federal budget.

Currently, the U.S. spends more on debt service than on national defense and around 50% more than on programs related to children.

“We are spending far more to pay off the debts of the past than to invest in the future,” said Marc Goldwein, a policy director at the Committee for a Responsible Federal Budget.

According to Goldwein, debt is fueling further debt growth and creating a cycle that is becoming increasingly difficult to break.

The increase in liabilities affects not only the government’s finances but also markets and American borrowers. The yield on 30-year U.S. Treasury bonds reached its highest level since 2007 on Tuesday, while the 10-year yield is near its highest point of Donald Trump’s second term.

Investors are demanding higher returns to hold U.S. debt. Uncertainty is being heightened by concerns about inflation, the federal deficit, increased bond issuance, and the future direction of Federal Reserve policy.

The 10-year Treasury yield directly affects mortgage rates, auto loans, and business borrowing costs. When it rises, financing becomes more expensive, lending conditions tighten, consumers may limit their spending, and companies may postpone investments.

At the same time, higher yields also increase the bill the U.S. government must pay to finance its debt.

“$40 trillion in debt does not exist only on the government’s balance sheets; the consequences are felt throughout the economy and, in one way or another, affect citizens’ pockets as well,” said Maya MacGuineas, president of the Committee for a Responsible Federal Budget.

Pressure on U.S. finances also increased in 2025, when Moody’s downgraded the U.S. debt and stripped the country of its last top credit rating.

Despite this, U.S. debt continues to rank just one level below the highest rating and above the sovereign debt of major economies such as France and Japan.

The Trump administration has taken measures to support the bond market. The Treasury Department announced that it would increase buybacks of long-term bonds in the coming months. According to analysts, this is intended to limit the rise in yields and borrowing costs.

Meanwhile, earlier this month, an auction for 30-year U.S. bonds recorded the highest yield since 2001. The result showed that investors are demanding greater compensation to hold U.S. debt.

Similar difficulties have emerged in other major economies. In the United Kingdom, France, Germany, and Japan, government bond yields are near their highest levels in recent years because of concerns about spending and deficits.

Washington is therefore facing an increasingly difficult dilemma: slowing the growth of debt and interest payments without harming the economy or key social programs.
