US National Debt Approaches and Nears $40 Trillion
The total US national debt is nearing the $40 trillion mark.
According to Treasury Department data, as of the end of July, the total public debt was approximately $39.8 trillion, approaching $40 trillion earlier than previously expected; interest payments are projected to reach $1 trillion for the first time, becoming the second-largest federal expenditure after Social Security, driven by high interest rates and the gap between spending and revenue.
In the bond and fiscal markets, investors continue to absorb new Treasury supply, but concerns about long-term interest rates and debt sustainability are rising; the flow of funds into safe assets and inflation hedges is putting pressure on the US government's financing costs, and the risk exposure of institutions and foreign creditors holding large amounts of Treasury securities is expanding.

The US national debt took about 30 years to grow from $1 trillion to $10 trillion, and only a few years to approach $40 trillion from $30 trillion, continuing a structurally accelerated path of spending expansion, tax cuts, and rising interest rates post-pandemic. Previous milestones were often accompanied by similar fiscal discussions but rarely resulted in substantial constraints.
On the capital side, the Treasury continues to issue new debt to cover deficits and interest payments, with the Federal Reserve and private markets as the main absorbers; resources are shifting from taxes and economic growth to debt rollover, motivated by the need to maintain existing spending commitments and avoid immediate tightening.
Similar patterns can be seen in Japan's long-term high debt and low growth model, as well as the post-war debt monetization experiences of various countries. The current situation in the US is in a mid-term phase of self-reinforcing debt interest and a lack of political consensus.
Structural judgments indicate capital concentration: when the scale of debt and interest payments form a self-accelerating cycle, fiscal resources further tilt towards creditors and existing spending commitments, compressing new policy space and shifting pricing power to the bond market and rating agencies.
