US Budget Deficit Surges to Highest Level Since March 2021

The US budget deficit reached its highest monthly level in over five years in July, driven by a surge in Medicare costs and ongoing interest on the federal debt.

The Treasury Department reported that the July shortfall totaled $432.3 billion, a 48% increase from the same period a year ago and the largest monthly deficit since March 2021.

Medicare expenses for the month were $174 billion, up from $103 billion in June and now at $955 billion for the full year, making it the single largest expenditure in July.

Other significant expenses included $141 billion spent on Social Security and $104 billion in net interest on the national debt.

Tariff refunds also had a significant impact, costing $33 billion as the administration continues to provide rebates for levies that the Supreme Court ruled illegal.

Additionally, the budget took a $99 billion hit because the first of the month was a nonbusiness day, accelerating various benefits outlays as well as Supplemental Security Income and Medicare payments.

The collective red ink across the first 10 months of the government's fiscal year rose to nearly $1.8 trillion and surpassed the same period in 2025.

Debt financing for the full year is behind only Social Security and Medicare as a proportion of government expenses.

For the fiscal year to date, the US has paid out $1.17 trillion on the $39.9 trillion national debt, of which $32.1 trillion is held by the public.

Debt servicing costs in the same period a year ago totaled $1.01 trillion.

Net interest, or the Treasury's gross interest minus the interest it receives, totaled $931 billion.

President Donald Trump had previously pressed the Federal Reserve to lower benchmark interest rates as a way to reduce debt costs, but has since held off on criticizing the central bank.

The Federal Reserve's stance on interest rates has been a topic of discussion, with markets initially looking for the Fed to raise rates to control inflation that has been running above the central bank's 2% target for more than five years.

However, recent benign inflation data and a soft payroll report have tempered those expectations, though futures traders aren't pricing in any chance of a rate cut for the next five years.

The Treasury Department's report highlights the ongoing fiscal challenges facing the US government, with the budget deficit continuing to rise despite efforts to reduce debt costs.

The administration's continued provision of rebates for levies that the Supreme Court ruled illegal has also had a significant impact on the budget.

The full-year Medicare expenses of $955 billion are a notable increase from previous years, and highlight the ongoing challenges facing the US healthcare system.

The US government's debt financing costs are also a significant concern, with the country paying out $1.17 trillion on the $39.9 trillion national debt for the fiscal year to date.
