U.S. Treasury marketable debt exceeded $30.2 trillion at the end of fiscal year 2025, driven by a $1.8 trillion deficit and interest payments climbing over $1 trillion. That interest tab surpassed both defense and Medicare spending, putting fresh pressure on federal finances as debt market strains mount.
Maturing Debt Wave
Nearly $3 trillion in Treasury debt matured during 2025, forcing the government to find new buyers just as traditional demand weakened. Foreign central banks reduced their holdings while the Federal Reserve continued shrinking its balance sheet from a 2022 peak of $8.5 trillion. The Treasury Department's regular refunding auctions now face thinner participation.
Hedge Fund Leverage Warning
Leveraged hedge funds held more than $1 trillion in notional short Treasury futures positions by March 2025, with leverage ratios exceeding 18-to-1. Federal Reserve Governor Lisa Cook specifically cited this leverage as a systemic vulnerability in November 2025, pointing to potential market instability. Regulators now monitor these positions closely after past disruptions.
Yields Resist Rate Cuts
Ten-year Treasury yields stayed above 4.3% throughout 2025 and 2026 despite Federal Reserve rate cuts. That kept 30-year mortgage rates stubbornly above 6%, frustrating homebuyers and housing markets. The disconnect between Fed policy and market pricing surprised many investors.
Recent Market Warnings
Treasury liquidity problems have flared repeatedly in recent years. The September 2019 repo market freeze forced emergency Fed liquidity injections, and the March 2020 crisis during the pandemic triggered massive bond purchases. Just last April, a tariff announcement caused immediate Treasury market deterioration, raising fresh concerns.
The Congressional Budget Office projects interest payments will reach $2.1 trillion by 2036 under current conditions. The Treasury must now find buyers for its next debt issuance cycle without traditional support.
