The consensus read on the Q2 National Accounts data is that the fiscal picture is stabilising: tax receipts at a record high, the Debt-to-GDP ratio nudging down, and US federal interest payments rising only modestly quarter-on-quarter. That reading is technically accurate and almost entirely beside the point.
What the Quarterly Squiggle Conceals
Interest payments by the federal government on its $40 trillion of Treasury debt rose by $7 billion in Q2 from Q1, reaching $312 billion for the quarter. Over the trailing 12 months, US federal interest payments totalled a record $1.22 trillion, up 240% since Q2 2020, when financial repression was near its peak. For context, the Committee for a Responsible Federal Budget puts the starting point at $345 billion in Fiscal Year 2020, meaning interest costs have nearly tripled in the span of a few years. The quarterly improvement is noise against that trajectory.
Tax receipts rose too, which the optimists are leaning on. Federal tax receipts climbed $20 billion in Q2 from Q1 and $95 billion year-over-year to a record $952 billion for the quarter. Over the 12-month period, they jumped $487 billion, or 14.9%, to $3.76 trillion. A stronger tax base does matter. But the ratio between the two is what exposes the structural problem: US federal interest payments consumed 32.5% of available tax receipts in Q2. The recent peak was 37.5% in Q3 2024, the worst reading since 1996. The direction of travel since 2022 has not been reassuring.
One distortion worth flagging: Q2 tax receipts were hit by tariff refunds after the Supreme Court scuttled part of the tariff regime. Refunds began flowing in May. Net tariffs collected over the quarter (tariffs received minus refunds paid) came in at negative $3.5 billion, against a positive $71 billion in the prior quarter. New tariffs under a different legal framework are now being imposed, so net tariff revenues should return to positive territory in the second half of 2026. Strip that distortion out, and the underlying receipts picture is somewhat less grim, though it does not fundamentally alter the interest-burden calculation.
The Rate Ratchet and What It Implies for US Federal Interest Payments
The average interest rate on the Treasury debt was 3.45% in July, up from 3.33% in March. The move looks gradual. The mechanism driving it is not. Maturing Treasury notes and bonds issued at ultra-low rates during the quantitative easing era are being replaced by new securities carrying materially higher coupons, and fresh issuance is being added to the pile without retiring anything. The direction is one-way until the stock of cheap legacy debt is fully turned over.
According to Yahoo Finance, net interest on the public debt totalled $963 billion between October 2025 and July 2026, equating to roughly $96.3 billion a month. That run rate, compounded by the rate ratchet still working through the debt stock, is what makes the quarterly snapshots feel inadequate as an analytical frame.
The Peter G. Peterson Foundation projects that net interest payments will total $16.2 trillion over the next decade, rising from an annual cost of $1.0 trillion in 2026 to $2.1 trillion in 2036. That projection assumes no fiscal correction. Given that the Congressional Budget Office projects the deficit-to-GDP ratio to remain in the same dismal range as the ~6% recorded across fiscal years 2022 through 2025, the assumption of no correction looks, at minimum, defensible.
The Debt-to-GDP ratio ticked down to 121.5% in Q2, as current-dollar GDP rose 1.9% quarter-on-quarter to $32.5 trillion, outpacing Treasury debt growth of 1.0% quarter-on-quarter to $39.5 trillion. The concept here, sometimes called “running the economy hot,” is that higher nominal growth and higher inflation erode the real debt burden over time even as the nominal debt stock keeps expanding. The Fed’s behaviour, cutting rates with inflation elevated in both late 2024 and late 2025, is consistent with that approach whatever its stated rationale. The bond market’s scepticism of this arrangement is reflected in a term premium that has not disappeared quietly.
Ed Yardeni coined the phrase “bond vigilantes” to describe bond investors who demand high yields in response to fiscal risk and inflation. That dynamic was acute in the 1980s and early 1990s. The phrase is no longer a historical curiosity. With the CBO projecting interest costs doubling to $2.1 trillion annually by 2036, the question of how long bond markets remain merely sceptical rather than actively disciplinary is the one the quarterly data cannot answer.
