U.S. Treasury Debt Surges $1.8 Trillion Following Debt Ceiling Adjustment

U.S. Treasury Debt Rises $1.8 Trillion Post-Debt Ceiling Adjustment

U.S. Treasury debt has experienced a substantial increase, rising by $1.8 trillion since the "One Big Beautiful Bill Act" lifted the debt ceiling. This surge brings the total national debt to $38 trillion in a little over one quarter, marking one of the largest quarterly accumulations of debt, surpassed only by the second quarter of 2020 when massive stimulus payments were issued during the pandemic.

Strategic Debt Issuance and Market Liquidity Enhancements

Treasury Secretary Scott Bessent has guided this period of significant debt expansion with a distinct strategy. A notable 60% of the new debt issuance has been concentrated in short-term Treasury Bills. This tactical prioritization aims to leverage anticipated declines in short-term interest rates and mitigate the risk of locking in higher rates over longer durations.

Alongside this issuance strategy, the Treasury reintroduced and expanded its Buyback Program. This initiative has notably improved bond market liquidity, which, as measured by the Bloomberg US Government Liquidity Index, has narrowed to 2.4 basis points, representing its narrowest level in 2.5 years. The program’s success stems from its ability to remove older, less liquid securities from the market and replace them with newer, more liquid issues.

This strategic management has coincided with a decline in interest rates, with 3-month T-Bills falling by 43 basis points and 10-year Treasury Notes declining by 27 basis points, contributing to a steepening yield curve.

Analysis of Market Reaction and Yield Curve Dynamics

The aggressive debt management and broader market expectations have led to a pronounced steepening of the yield curve. The spread between the 10-year Treasury yield and the 2-year Treasury yield (10s-2s spread) has widened significantly from 29 basis points at the beginning of 2025 to over 50 basis points, marking its steepest slope since early 2022. This phenomenon is primarily driven by a decline in short-term yields, with the 2-Year yield dropping from 4.40% in January to approximately 3.70%, fueled by market anticipation of Federal Reserve rate cuts, stable inflation forecasts, and expectations of a soft economic landing.
