The U.S. national debt exceeded $40 trillion for the first time on Tuesday, according to a Treasury Department statement released Wednesday. The outstanding public debt stood at $40.05 trillion at market close, marking a one-third increase in less than five years and underscoring the government’s persistent reliance on borrowing.
The milestone arrives amid ongoing congressional inaction on fiscal consolidation, as lawmakers continue to resist revenue-raising measures such as tax increases and politically sensitive spending cuts to entitlement programs. Analysts note that substantive action has historically occurred only under market pressure, with no near-term reduction in the deficit-to-GDP ratio expected by economists, the Congressional Budget Office, or major financial institutions.
U.S. Treasury Secretary Scott Bessent announced an expansion of the department’s buyback program for longer-dated securities on Wednesday, following a series of auctions that pushed borrowing costs to multi-year highs. The move contributed to a decline in long-term yields after the announcement. At Thursday’s auction of 30-year bonds, the highest financing costs for such an issuance in 25 years were recorded, while a sale of 10-year notes the prior day saw the highest costs since 2007.
The debt’s rapid ascent—from $30 trillion in January 2022—reflects the government’s elevated borrowing needs, driven by persistent budget deficits outside of extraordinary events such as major wars or pandemics. Bessent has cited deficit reduction as a key motivation for his entry into public service, though policymakers have yet to implement measures sufficient to alter the trajectory.
Economists, including Deutsche Bank’s Matthew Luzzetti, emphasize that while the symbolic threshold of $40 trillion may draw attention, it carries no inherent impact on debt dynamics. The focus remains on rising Treasury yields, which increase the cost of servicing the nation’s unprecedented debt load.
