America’s red ink is no longer an abstraction. The federal tab has climbed to roughly $38.5 trillion, a figure so large it is easier to picture in political slogans than in balance sheets. Yet every dollar of that borrowing is someone’s asset, and the real story is who holds the IOUs that keep the United States government running.
To understand the risks and leverage in that $38.5 trillion, I need to break the debt into its main pieces and follow the money from Washington’s bond auctions to the households, funds, agencies, and foreign governments that ultimately own it. Only then does the national debt stop being a single scary number and start looking like a web of obligations that tie together retirees, banks, central banks, and global investors.
How big the debt is and how it is sliced
On Capitol Hill, the official scorekeeper puts the federal tab just shy of the headline number. The Joint Economic Committee’s Republican staff notes that, as part of the Growth of the national debt, total gross national debt is $38.43 trillion, a figure that includes both bonds sold to the public and IOUs the government writes to itself. Of that, debt held by the public is $30.8 trillion, while the rest is intragovernmental, the accounting claims owed to trust funds like Social Security and Medicare.
The pace of borrowing has been brisk. In a separate snapshot, the same dashboard, Released January, highlights a $2.25 trillion Change in gross national debt from Jan 07, 2025 to Jan 07, 2026, and pegs the Gross national debt per person at $285,127. Earlier reporting framed the picture slightly differently, noting that when the total was $36.2 trillion, about $27.2 trillion of that was held domestically, a reminder that most of the IOUs are owed to investors inside U.S. borders even as the overall pile keeps growing.
Debt held by the public: households, funds and the Fed
When people talk about “the markets” financing Washington, they are really talking about a long list of buyers that fall under the label Debt Held by the Public. One breakdown of that category explains that more than two-thirds of public debt is held by domestic holders, and that the Composition of Debt Held by the Public includes everything from mutual funds and pension plans to banks, insurance companies, and individual savers who buy Treasury bills and notes. In that view, the IOUs are spread widely across the financial system, not concentrated in a single giant creditor.
Another slice of the same data, under the heading Debt Held, emphasizes that More than two-thirds of public debt is held by domestic holders and that the list of owners runs from the Federal Reserve to state and local governments, as well as Savings Bonds and Other Investors. A separate section on Domestic Holders of Federal Debt underscores that The Federal Government Has Borrowed Trillions and asks Who Owns All that Debt, before detailing how On October the nation’s gross debt eclipsed a key threshold. Earlier analysis put numbers on that split, noting that when the total stood at $36.2 trillion, roughly $27.2 trillion was held domestically, with a sizable share of that owned or influenced by the Federal Reserve itself.
Intragovernmental IOUs: when Washington owes Washington
Not every federal IOU is held by outside investors. A large chunk of the $38.43 trillion total is intragovernmental debt, the promises the Treasury has made to other federal accounts. The Joint Economic Committee’s As of January snapshot puts intragovernmental debt at $7.62 trillion, a reminder that programs like Social Security and Medicare finance future benefits by holding special Treasury securities. These IOUs do not trade on Wall Street, but they are real obligations that will have to be honored with future taxes or borrowing.
Economists sometimes treat these internal claims differently from market debt, but they still matter for fiscal politics. A breakdown of the Components of US notes that a wide range of government agencies hold US national debt, and that two major examples are Social Secur and other trust funds that invest their surpluses in Treasury securities. When those trust funds move from surplus to deficit, the Treasury must redeem those IOUs, effectively turning intragovernmental debt into new borrowing from the public.
Foreign creditors: allies, rivals and a shrinking share
Outside U.S. borders, the IOUs are spread across central banks, sovereign wealth funds, and private investors. Earlier this decade, foreign investors held about $8.5 trillion of US Treasury bonds, according to an analysis of how Shifts in US policy may have an impact on global investors. That report describes how Foreign investors, including central banks, banks, and pension funds, treat Treasury securities as a safe place to park reserves, which in turn helps keep U.S. borrowing costs lower than they might otherwise be.
Yet the foreign share of U.S. IOUs has been drifting down. A separate review of how Treaurys fit into global portfolios notes that U.S. Treasurys have long been viewed as a safe, highly liquid investment to lenders worldwide, but that foreign investors now hold a shrinking share of U.S. debt, a trend some analysts warn threatens America’s ability to lead. Within that foreign slice, Japan is the biggest foreign holder of U.S. Treasury securities, with holdings that have recently exceeded those of China, which has been gradually trimming its exposure. Other major creditors include the United Kingdom and financial centers that act as custodians for global investors, while Japan and China remain the marquee names in every ranking of foreign holders.
The Federal Reserve and private investors in the Treasury market
Behind the scenes, the Federal Reserve is both the government’s bank and one of its biggest creditors. After multiple rounds of quantitative easing, the central bank amassed a large portfolio of Treasury securities, and a data series labeled Assets tracks Securities Held Outright, U.S. Treasury Securities, All, Wednesday Level on the Fed’s balance sheet. Those holdings fluctuate as the central bank lets bonds mature or sells them outright, but they still represent trillions of dollars of federal IOUs sitting inside the nation’s monetary authority rather than in private hands.
Outside the Fed, private investors are the single largest bloc of creditors. A review of Key facts about the U.S. national debt notes that Private investors are the biggest holders of U.S. government debt, a group that includes mutual funds, pension funds, insurance companies, banks, broker-dealers and others. Earlier breakdowns of Who holds US debt explained that Three-quarters of the $36.2 trillion US debt, approximately $27.2 trillion, was held domestically, of which a significant share was held by the Federal Reserve, with the rest spread across those private buyers. The Treasury’s own All federal debt dataset defines debt held by the public as all federal debt held by individuals, corporations, state or local governments, Federal Reserve Banks, foreign governments, and other entities outside the federal government, and lists the mix of Treasury Bills, Notes, Bonds, and Treasury Inflation-Protected Securities that make up the IOUs those investors own.
