U.S. total national debt reaches a record high of about $40.53 trillion
According to the U.S. Treasury’s “Debt to the Penny” dataset, as of October 26, 2026, the total public debt outstanding was $40,528,358,939,415.85, or about $40.53 trillion, a record high. The figure includes about $32.64 trillion in debt held by the public and about $7.89 trillion held by the government intragovernmental holdings.
Treasury data showed that total debt first surpassed the $40 trillion mark around August 18, 2026. As of the end of fiscal year 2026 (September 30, 2026), the total was about $40.17 trillion. It then continued to rise, reaching about $40.46 trillion on October 23 and further increasing to about $40.53 trillion on October 26. The series is updated daily and reflects the actual outstanding debt from the previous business day.
The total public debt is made up of various securities issued by the Treasury, including Treasury bills, notes, bonds, Treasury Inflation-Protected Securities, and government account series securities. Among them, the portion held by the public is held by individuals, companies, the Federal Reserve, foreign governments and others; the government intragovernmental holdings portion mainly includes trust funds such as Social Security and Medicare. Independent analysis shows that by the end of fiscal year 2026, debt had increased by about $2.53 trillion from the previous year.
U.S. national debt is subject to a statutory debt ceiling, and Congress has the authority to adjust or suspend it. The Bipartisan Policy Center previously estimated that debt could reach the approximately $41.1 trillion ceiling between late winter and midyear 2027. In recent years, debt growth has mainly been driven by persistent fiscal deficits, including defense, Social Security, Medicare and interest expenses.

After U.S. public debt broke through $40 trillion in August 2026, it continued to climb, reaching about $40.53 trillion on October 26. From about $40.17 trillion at the end of fiscal year 2026 to the latest data, it increased by about $360 billion in roughly one month, showing no obvious slowdown in the pace of deficit financing. This growth extends the trend of debt more than doubling over the past decade, driven mainly by mandatory spending, interest costs and cyclical deficits.
In terms of composition, about 80% is held by the public, including domestic and foreign investors and the Federal Reserve, and about 20% is held intragovernmentally. Interest payments have become one of the largest items in the budget, second only to Social Security and Medicare, and some analyses say they have exceeded defense spending. The continued rise in debt runs alongside the debt-ceiling mechanism, and Congress will need to act again before the limit is reached, otherwise extraordinary financing measures may be required.
Compared with history, the journey from $1 trillion to $40 trillion took decades of acceleration; in recent years, the move from $30 trillion to $40 trillion took only a few years. Significant increases have occurred under different presidential terms, and recent growth is partly related to defense spending, tax policy and economic stimulus. The ratio of debt to GDP has remained at a high level in recent years, with the exact percentage varying depending on the calculation method (whether government intragovernmental holdings are included).
This milestone changes the benchmark for public discussion of the debt level — from being “close to $40 trillion” to having “surpassed $40.5 trillion”; what has not changed is the basic pattern of debt growth driven by persistent structural deficits. Because Treasury data are updated daily and precise to the cent, the next points to watch are the daily increases from late October into November, the ratio of interest spending to fiscal revenue, and the specific timeline for debt-ceiling negotiations.
