US national debt exceeds $40 trillion for first time

The gross national debt of the United States has surpassed the $40 trillion mark for the first time, according to government data. This staggering figure exceeded earlier forecasts, driven partly by former President Donald Trump's invalidated tariffs. The debt growth is attributed to an increase in borrowing, as longer-term U.S. obligations linked to social security and healthcare have risen, alongside growing interest payments.

The total public debt outstanding was reported at $40.05 trillion at the close of business on Tuesday, as released by the U.S. Treasury Department.

This development follows an earlier prediction by the Congressional Budget Office, which had anticipated borrowing to reach $39.4 trillion by the end of fiscal year 2026. Concerns over inflation, the Middle East war, and government spending have heightened investor worries, leading to a rise in borrowing costs. Yields on long-term Treasury bonds climbed to their highest level since 2007, reflecting escalating price pressures due to the Iran war and anxiety surrounding U.S. deficit spending.

The federal government operates at a deficit, borrowing money to cover obligations such as war spending and tax cuts. Jessica Riedl, a budget and tax fellow at the Brookings Institution, commented that the U.S. government has been on an unsustainable path with deficits, even during times of peace and prosperity, with recent deficits nearing 6-7% of GDP.

The increasing deficits are a result of inflation pushing interest rates higher and the effects of an aging population on healthcare costs and tax policies that fail to generate sufficient revenue for federal spending commitments.

Michael Peterson, chairman and CEO of the Peter G. Peterson Foundation, attributed the growing debt to factors like an aging population, rising healthcare costs, and inadequate tax policies. He highlighted that interest expenses, which have become the fastest-growing government program, amount to more than $3 billion daily and will total $16 trillion over the next decade.

While the gross debt represents a symbolic threshold, many economists consider debt held by the public a more economically meaningful measure. However, Riedl noted that these figures serve as psychological landmarks that alert financial markets to the need for reevaluation of rising debt levels. Federal borrowing surged during the 2007-2009 Great Recession and has continued following the government's response to the Covid-19 pandemic.

Nevertheless, experts warn that the current trajectory of U.S. budget spending has not been effectively addressed by Congress or administrations, potentially leading to higher borrowing costs for consumers and businesses, which could strain the economy.
