U.S. National Debt Crisis and Bond Market
What's Happened So Far
The U.S. national debt surpassed $40 trillion in August 2026, prompting the Treasury Department to intervene in bond markets through expanded purchases of long-term government debt. Treasury Secretary Scott Bessent's buyback efforts initially failed to arrest yield increases, leading officials to consider using the Treasury General Account to finance operations. The interventions coincided with a broader global bond sell-off driven by persistent inflation concerns and Middle East escalations, with yields climbing to multidecade highs across major economies throughout September and early October.
The 10-year U.S. Treasury yield breached 5% in mid-September and subsequently climbed to 5.34% by early October—the highest level since 2002. Rising Treasury yields cascaded through financial markets, pushing 30-year mortgage rates to 7.28%, their highest point since late 2023, while straining borrowing costs for households and governments worldwide. In October, the International Monetary Fund warned of potential "disorderly" yield spikes amid mounting global debt pressures. The Treasury Department reported the fiscal 2026 budget deficit reached $1.992 trillion, the third-largest on record, exacerbating market concerns over long-term fiscal sustainability.
