The U.S. national debt has surpassed the $40 trillion mark, with approximately one-fourth of that total—over $11.5 trillion—accumulated during President Donald Trump's first term and the opening half of his second term, according to Treasury Department data [1]. The increase in federal spending has been driven in part by an aging population, which has led to higher enrollment in Social Security and Medicare, thereby pushing entitlement program expenditures and federal budget deficits higher [1].
The recent rise in interest rates, combined with the larger national debt, has intensified the situation, with annual interest expenses for servicing the national debt now exceeding $1 trillion [1]. The gross national debt, which includes all U.S. government obligations such as those held in intragovernmental accounts like the Social Security trust funds, is nearing $40 trillion, while debt held by the public stands at over $32 trillion [1].
When Trump assumed office on January 20, 2017, the gross national debt was $19.9 trillion. Key contributors to the debt increase during his tenure include the Tax Cuts and Jobs Act and significant spending on COVID-19 relief measures [1]. The largest U.S. budget deficit in history occurred in fiscal year 2020, the last full fiscal year of Trump's first term, when the federal government ran a deficit exceeding $3.1 trillion, largely due to bipartisan COVID relief measures [1].
White House spokesman Kush Desai emphasized that addressing what he described as 'Joe Biden's reckless fiscal mismanagement' has been a priority for the Trump administration, citing efforts to reduce waste, fraud, and abuse in government spending, and to improve the debt-to-GDP ratio [1]. A White House official also attributed a significant portion of the debt growth during Trump's first term to the historic pandemic, while criticizing subsequent COVID stimulus spending under President Biden for exacerbating inflation and increasing government borrowing costs [1].
CONCLUSION
The U.S. national debt has reached unprecedented levels, with over $11.5 trillion added during President Trump's time in office, driven by entitlement spending, tax policy, and pandemic relief measures. Rising interest rates have further increased the cost of servicing this debt, intensifying fiscal pressures. The market impact is high, as the growing debt and associated interest expenses pose significant challenges for future fiscal policy.
