CBO: US deficit hit $1.4T in first nine months of FY2026 as net interest rises
The numbers lawmakers see each month are only part of the story, but the direction matters. In its Monthly Budget Review for June 2026—released July 9, 2026—the Congressional Budget Office (CBO) estimates the federal budget deficit totaled $1.4 trillion in the first nine months of FY2026.
For residents, the practical significance isn’t that a deficit headline automatically changes a grocery receipt or paycheck tomorrow. It’s that CBO says the deficit is widening for a specific budget reason: outlays are rising faster than revenues. And CBO flags another cost that can increasingly dominate the budget—net interest on the public debt.
What changed in the deficit pace
CBO estimates that, in the first nine months of FY2026, revenues rose by $142 billion (+4%) while outlays increased by $178 billion (+3%). Because spending is growing faster than income to the Treasury, the gap shows up in the year-to-date deficit total—not just in one unusual month.
Where the pressure shows up: net interest
The most budget-relevant signal in the report is the growth in net interest on the public debt. CBO estimates that net interest outlays rose by $98 billion (+13%) in the same first-nine-month window.
In CBO’s explanation, the higher interest costs reflect both a higher debt level and higher long-term interest rates, with declines in short-term rates partially mitigating the overall increase.
That mix matters for Congress because net interest isn’t a line item that can be trimmed through routine appropriations tweaks. It’s driven by debt and the broader interest-rate environment—so when it accelerates, it can crowd out other priorities in future budget bargaining.
How this can create “household pressure” later—without claiming instant price effects
Higher interest costs don’t automatically mean higher prices today. But they can tighten fiscal flexibility—what lawmakers can afford to fund, pause, or redesign over time. CBO’s framework points to a longer-run tradeoff: if debt-service costs keep rising, Congress may face tougher decisions about taxes and spending levels, or about how quickly new commitments can be scaled.
In other words, the pressure is less about immediate, direct consumer bills—and more about narrowing the set of budget choices available when the next round of fiscal negotiations arrives.
Reading the timing correctly: why monthly comparisons can look odd
CBO also cautions that some month-to-month changes can be distorted by timing shifts—including payments that fall around weekends. That context doesn’t erase the main year-to-date direction, but it matters for readers comparing one calendar month to the same month last year.
Extra context for Congress: different lenses on the same CBO snapshot
Budget stakeholders often translate CBO’s year-to-date totals into a broader running deficit picture. The Committee for a Responsible Federal Budget uses CBO-based estimates to track a rolling 12-month deficit, while a U.S. Joint Economic Committee fiscal update summarizes the same deficit-to-date material for a congressional audience.
What to watch next
With CBO describing a widening deficit because spending is rising faster than receipts—and with net interest growing quickly—the near-term congressional question is not whether lawmakers will argue about deficits. It’s how they account for debt-service growth in upcoming budget and appropriations discussions.
- Whether budget writers treat net interest as a baseline cost center that shapes discretionary bargaining.
- Whether deficit-control discussions place greater emphasis on revenue changes, spending restraint, or both (CBO describes what’s happening, not prescriptions).
- Whether committees explain the difference between timing-distorted monthly comparisons and steadier year-to-date patterns.
