The U.S. Treasury’s borrowing showed no signs of slowing as the U.S. headed deeper into fiscal year 2026, with the Congressional Budget Office (CBO) reporting that another $1 trillion was added to the federal deficit in the first five months of the year.

The monthly budget review from the CBO, updated to February 2026 and released yesterday, showed that the government is estimated to have borrowed $308 billion last month alone.

Of course, with more borrowing comes higher interest costs on the debt. Between October 2025 (when the 2026 fiscal year started) and February, the Treasury spent an additional $31 billion on net interest on public debt, compared to the prior year. As a result, in just five months, the Treasury forked out a total of $433 billion to service public debt, which is now nearing $38.9 trillion.
