The government’s interest bill on public debt has climbed to a level that is now hard to miss. The Congressional Budget Office said net interest reached $963 billion in the first 10 months of fiscal year 2026, equal to about $3.18 billion a day.
That means the Treasury was spending more than $3 billion every day just to service the debt, even before the fiscal year is finished. The total was up $117 billion, or 14%, from the same stretch a year earlier, and the agency also lifted its full-year deficit forecast to $2.1 trillion.
The daily figure is simple math: $963 billion spread across 303 days works out to roughly $3.18 billion each day. On a monthly basis, that is about $96.3 billion. It is not a small drift in the ledger. It is a pace that keeps interest costs near the scale of major federal spending categories and pushes the government’s financing burden higher even as the year is still running.
Phil Swagel said declines in short-term rates partially mitigated the overall rise in interest payments, but they did not reverse it. The CBO said the increase in net interest reflected a larger debt balance than in the first 10 months of fiscal year 2025 and higher long-term interest rates, a combination that kept borrowing costs elevated even after some relief from shorter rates.
The deficit picture moved in the same direction. Deficits totaled $1.8 trillion in the first 10 months of fiscal year 2026, which was $169 billion more than in the same period a year earlier. The CBO’s new $2.1 trillion full-year projection is $200 billion above the estimate it made in February 2026, showing that the federal gap has widened faster than officials had expected when the year began.
That backdrop matters because the debt load itself is already enormous, and higher rates make each new round of borrowing more expensive to carry. The CBO has framed the problem against a government debt burden that is nearing $40 trillion and a debt-to-GDP ratio of 122%, a combination that leaves less room for error if long-term rates stay high.
The unresolved issue is not whether interest costs are rising; they are. The question now is how long the Treasury can absorb a bill of more than $3 billion a day while deficits remain near $2 trillion and the debt keeps growing faster than the savings from lower short-term rates can offset.
