US National Debt Statistics (2026)

The US national debt passed $40 trillion on August 20, 2026 and stood at about $40.4 trillion on October 15, 2026, a record (see the table below). The Treasury reports the figure daily through its Debt to the Penny dataset; across fiscal 2026 the total grew by about $2.5 trillion, or roughly $6.9 billion a day.

That headline number has two parts. Roughly $32.5 trillion is debt held by the public, money actually borrowed from investors, and about $7.9 trillion is intragovernmental debt the government owes to its own trust funds. The public share is the one economists watch most closely.

Not all debt is the same. Debt held by the public (about 81% of the total) is what the Treasury has sold to households, companies, banks, foreign governments, and the Federal Reserve. It is real borrowing from outside the government and the number that drives interest costs.

Intragovernmental debt (about 19%, or ~$7.9 trillion) is money one part of the government owes another, mostly Social Security and federal retirement trust funds that hold special-issue Treasury securities. About $2.3 trillion sits in the Social Security old-age trust fund alone.

Trillions are hard to picture, so it helps to divide. Spread across roughly 343 million residents (Census population clock), about $40.4 trillion is close to $118,000 of federal debt per person; the Joint Economic Committee's dashboard put it at about $289,000 per household in July 2026 (see the table below).

Framed per taxpayer, the figure is higher still, around $280,000, because far fewer people pay net federal income tax than live in the country. These per-person numbers are derived estimates and shift with which population base and which debt measure (gross or public) you use.

The trajectory is steep. Gross federal debt was about $5.7 trillion in 2000, roughly $13.6 trillion by 2010 after the financial crisis, and $26.9 trillion by 2020 as the pandemic hit (see the chart and table below). It ended fiscal 2026 at $40.2 trillion, more than $13 trillion higher in six years.

Two forces dominate that curve: recessions, which crater tax revenue and trigger emergency spending, and structurally rising outlays on Social Security, Medicare, and now interest. The debt roughly doubled in the 2000s and again over the 2010s, and it is on pace to keep compounding.

The raw dollar figure matters less than the debt relative to the size of the economy. On a gross basis the debt is about 123% of GDP; the cleaner measure economists prefer, debt held by the public, is about 101% of GDP and rising (see the chart above).

That is near the all-time high. Public debt last approached this level right after World War II, peaking at 106% of GDP in 1946. On CBO's current baseline the ratio blows past that record within a few years and reaches 120% by 2036.

The debt grows because the government runs a deficit almost every year: it spends more than it collects and borrows the difference. FY2025 ran a deficit of about $1.78 trillion, and FY2026 came in at $1.99 trillion, above the roughly $1.9 trillion (5.8% of GDP) CBO projected in February (see the table below).

That is an unusually large gap outside a recession or war. Deficits spiked to $3.1 trillion in the COVID year of 2020, narrowed toward $1.4 trillion in 2022, then widened again. Persistent deficits near $2 trillion are what keep the debt compounding higher.

The most striking change is the cost of carrying the debt. Net interest reached $1.05 trillion in fiscal 2026, up from $345 billion in 2020, as both the debt and interest rates climbed (see the chart above). That is about $2.9 billion in interest every single day.

CBO projected 3.3% of GDP for 2026, above the previous 1991 record, and interest now consumes about 19.5% of all federal revenue ($1.05 trillion of $5.40 trillion in FY2026). It is the fastest-growing part of the budget, and unlike most programs it cannot be cut without defaulting.

To see how large that has become, compare it to major programs. In fiscal 2026 net interest ($1.05 trillion) ran ahead of national defense ($965 billion) and just behind Medicare ($1.07 trillion), per the Treasury's Monthly Treasury Statement, and the Peterson Foundation expects it to exceed Medicare through the coming decade.

That crowding-out is the real fiscal risk. Every dollar spent servicing past borrowing is a dollar not available for defense, research, infrastructure, or tax relief, and higher rates make the problem compound on itself as maturing debt is refinanced at today's yields.

A common myth is that the debt is mostly owed to China. In reality most of it is owed to Americans and to the government itself. Of the ~$32.5 trillion held by the public, roughly 71% is domestic and about 29% is foreign (see the table below).

Domestic holders include the Federal Reserve (about $4.6 trillion), US mutual and money-market funds, banks, state and local governments, pension funds, insurers, and individual savers holding Treasuries and savings bonds. The single largest bloc, though, is the diverse set of American investors.

Foreign investors held $9.33 trillion of Treasuries in August 2026, a little below the record $9.49 trillion set in February (see the table below). Japan is the largest at about $1.07 trillion, followed by the United Kingdom at a record $1.01 trillion and mainland China at about $591 billion; together the top three own about 29% of foreign-held US debt.

China's holdings have drifted lower over the past decade even as the total foreign stock has grown, and the UK is now within about $60 billion of Japan, a reminder that demand for Treasuries is broad. Financial centers like Luxembourg, the Cayman Islands, and Belgium also show large balances that reflect custodial flows rather than true end owners.

The Federal Reserve is effectively the largest single holder of Treasuries, owning roughly $4.57 trillion as of mid-October 2026 (Fed H.4.1). It accumulated much of that through quantitative easing, buying government bonds to hold down long-term interest rates during and after the 2008 and 2020 crises.

From 2022 the Fed did the reverse, letting bonds mature without full reinvestment (quantitative tightening) to shrink its balance sheet. That has since turned: its Treasury holdings were up about $373 billion from a year earlier in October 2026, almost all of it in Treasury bills.

The independent Congressional Budget Office does not see the trend reversing. In its February 2026 outlook, debt held by the public rises from 101% of GDP in 2026 to 108% by 2030 and 120% by 2036, blowing past the 1946 record along the way (see the table below).

Deficits are projected to grow from about $1.9 trillion in 2026 to $3.1 trillion in 2036, and net interest roughly doubles again to nearly $2.1 trillion, reaching 4.6% of GDP. Over the full decade CBO expects interest payments alone to total about $16 trillion.

The debt ceiling is a legal cap on how much the Treasury can borrow, separate from the spending decisions that create the debt in the first place. Raising or suspending it does not authorize new spending; it lets the government pay bills Congress has already approved.

Standoffs over the ceiling have become a recurring source of market anxiety because a failure to raise it in time could trigger a first-ever US default. Rating agencies have cited the repeated brinkmanship, alongside the fiscal trajectory itself, in downgrading US credit from the top AAA tier.

For everyday investors, the debt is less a reason to panic than a reason to plan. Heavy government borrowing tends to keep interest rates and Treasury yields higher than they otherwise would be, which is good for savers and bond buyers but raises borrowing costs on mortgages and loans.

The practical takeaways are ordinary and durable: own a globally diversified mix of stocks and bonds rather than betting on any single macro outcome, use higher yields to your advantage in cash and short-term Treasuries, and remember that US assets have compounded through every prior debt scare. Fiscal risk is real, but market timing on it is a losing game.
