US National Debt Statistics (2026)

The US national debt crossed about $39.4 trillion in July 2026, a record, and it keeps setting new ones roughly every few weeks (see the table below). The Treasury reports the figure daily through its Debt to the Penny dataset, and in recent weeks the total has grown by about $6 billion a day.

That headline number has two parts. Roughly $31.7 trillion is debt held by the public, money actually borrowed from investors, and about $7.7 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 80% 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 20%, or ~$7.7 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 342 million residents, about $39.4 trillion is close to $115,000 of federal debt per person, or about $289,000 per household on the Joint Economic Committee's dashboard (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 has since added more than $12 trillion 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 $1.8 trillion, and CBO projects roughly $1.9 trillion for FY2026, about 5.8% of GDP (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 crossed $1 trillion a year in 2026, up from $345 billion in 2020, as both the debt and interest rates climbed (see the chart above). That is about $2.8 billion in interest every single day.

At 3.3% of GDP, interest has already eclipsed its previous 1991 record, and it now consumes about 18.6% of all federal revenue. 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. Net interest now runs ahead of what the government spends on national defense and is on track to exceed Medicare spending through the coming decade, according to the Peterson Foundation.

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 ~$31.7 trillion held by the public, roughly 70% is domestic and about 30% is foreign (see the table below).

Domestic holders include the Federal Reserve (about $4.9 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 a record $9.5 trillion of Treasuries in early 2026 (see the table below). Japan is the largest at about $1.24 trillion, followed by the United Kingdom at roughly $897 billion and mainland China at about $693 billion; together the top three own about a third of foreign-held US debt.

China's holdings have drifted lower over the past decade even as the total foreign stock has grown, 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 $4.9 trillion. 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.

Since 2022 the Fed has been doing the reverse, letting bonds mature without full reinvestment (quantitative tightening) to shrink its balance sheet. That withdrawal of a big, price-insensitive buyer is one reason Treasury yields, and the government's interest bill, have stayed elevated.

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.
