US July Deficit Hits $432B, Raising 10-Month Total to $1.8T

The U.S. budget deficit surged to $432.3 billion in July, reaching its highest monthly level since March 2021 and pushing the 10-month fiscal year shortfall to nearly $1.8 trillion.

This latest red ink represents an increase of roughly 48% from the same period a year ago, driven by a combination of surging healthcare costs, legal rebate payouts, and a calendar quirk that shifted payment dates.

What Drove the July Spike?

The sharp acceleration in monthly spending stemmed from several distinct outlays across federal agencies. Medicare expenses totaled $174 billion for July, jumping significantly from $103 billion in June and bringing total Medicare outlays to $955 billion for the fiscal year to date.

This outpaced both Social Security at $141 billion and net interest payments at $104 billion for the month, making healthcare the single largest expenditure category.

Beyond entitlement spending, the federal ledger absorbed specific one-off hits:

• Calendar shifts: The first of the month fell on a nonbusiness day, accelerating $99 billion in benefit outlays, including Supplemental Security Income and Medicare payments, into July.
• Tariff refunds: The government paid out $33 billion in tariff rebates after the Supreme Court ruled certain levies illegal.

Mounting Debt Servicing Costs

For the fiscal year to date, the U.S. has paid $1.17 trillion in interest on the national debt, which stands at $39.9 trillion with $32.1 trillion held by the public. This compares to $1.01 trillion in debt servicing costs incurred during the same 10-month window a year prior.

As borrowing costs remain elevated alongside the expanding national debt, interest payments continue to consume a growing share of federal revenue, compounding the structural pressures behind the widening deficit.
