Treasury spent $276 billion in interest on the national debt in the final three months of 2025, says the CBO—up $30 billion from a year prior

The CBO reports the Treasury paid $92 billion per month in net interest on the public debt in the final three months of 2025—$276 billion for Oct–Dec, up 13% year-over-year—and the government spent $1.22 trillion on interest for fiscal 2025 as the national debt reached $38.4 trillion. The CBO also noted a narrower FY2026 Q1 deficit of $601 billion (down $110 billion year-over-year) driven by a $141 billion revenue gain including a $70 billion rise in customs duties, even as interest outlays rose $31 billion; policymakers face mixed relief from slowing inflation (Core PCE forecast to ease through 2026) but persistent long-term rates and legal/legislative risks around tariffs that could materially affect revenues.

Analysis

Market structure: Rising net interest ($276B in Q4; $1.22T FY2025) and a $38.4T debt stock imply persistent Treasury supply pressure and upward pressure on long-term yields. Winners: money-market funds, short-term Treasury ETFs (SHV/BIL), floating-rate credit and banks that can widen NIM; losers: long-duration bonds (TLT), REITs (VNQ), and long-duration growth equities. Higher long yields and slower Fed cuts support a firmer USD and weigh on gold and rate-sensitive commodities.

Risk assessment: Tail risks include a Supreme Court reversal of tariffs that could remove tens of billions of annual revenues and/or enactment of $2,000 transfers that could add hundreds of billions to deficits; either outcome would steepen the yield curve and widen funding costs. Near-term catalysts are the next FOMC (≈2 weeks), the Court ruling (months), and monthly Treasury issuance plans; medium-term (3–12 months) risk is political/legislative response increasing issuance. Hidden dependency: bank deposit beta — if deposit rates rise faster than loan yields, bank equity upside is capped.

Trade implications: Favored positioning is short-duration cash (SHV/BIL) for 3–6 months, selective long-bank exposure (JPM, BAC) as 10y stays elevated, and hedging/removal of long-duration bond risk with TLT puts or inverse ETFs. Consider pair trades: long regional-bank ETF (KRE) vs short REITs (VNQ) on a steepener. Use 1–3 month option structures to express views around FOMC and the Court decision.

Contrarian angles: The market underprices fiscal tail risk — if tariffs are voided and transfers enacted, 10y could reprice >50–75bps quickly; conversely, if inflation continues to decelerate toward CBO’s 2.5% by Q4 2026 and issuance is stable, long yields may compress. This leaves opportunities to buy oversold corporate credit and long-duration municipals only after a clear >50bps dislocation and visible policy clarity.

Key Decisions for Investors

• Allocate 2–3% of portfolio to short-term Treasury ETFs (SHV or BIL), laddered 1–6 months, and hold until 10yr UST yield declines by >50bps from current levels or the Fed signals a sustained easing cycle (watch for two consecutive FOMC cuts).
• Establish a 2% long position split across JPM (+1%) and BAC (+1%); trim or stop‑loss if 10yr UST falls below 3.50% or if bank deposit betas accelerate (deposit cost >60% of move in 10yr).
• Reduce long-duration bond exposure to <1% of portfolio and buy 3-month TLT ATM puts equal to 0.5% portfolio notional (cost budget ≤0.2% portfolio) as hedge against a >40bp uptick in 10yr within 90 days.
• Initiate a 1:1 pair trade (1% NAV each): long KRE (regional-bank ETF) and short VNQ (REIT ETF) with a 3–6 month horizon; exit if 10yr >4.25% (take profits) or if 10yr <3.25% (cut losses).
• Prepare a tactical reaction plan for the Supreme Court tariff ruling within 90 days: if tariffs are reversed, deploy a 1–2% short basket on import‑exposed retailers (e.g., NKE, PVH) via put spreads; if tariffs stand and $2k transfers gain traction, move 2% into long-duration Treasury exposure as a defensive play.
