FRED has several data series related to the US national debt, and today we analyze these series to reveal who holds that debt.
Components of US National Debt
The FRED graph above shows total US national debt (blue solid line) broken down into its two primary categories based on ownership:
- debt held by the public (orange dashed line)
- debt held by government agencies and trusts (teal dotted line), also known as intra-governmental holdings
A wide range of government agencies hold US national debt; two major examples are Social Security funds and federal employee retirement funds. The remainder of the debt is held by the public, including the Federal Reserve. As of the third quarter of 2024, debt held by the public was about $28 trillion, and intra-governmental holdings were about $7 trillion.
Breakdown of Debt Held by the Public
Our second FRED graph further divides debt held by the public (orange dashed line) into two categories:
- debt held by Federal Reserve Banks (teal dotted line)
- debt held by private investors (blue solid line)
After multiple rounds of quantitative easing, the Federal Reserve has become the largest single holder of US national debt. The Fed’s holdings increased from about $1 trillion at the end of 2010 to a peak of more than $6 trillion in 2022. But private-sector debt holdings grew even more significantly, rising from $8 trillion at the end of 2010 to nearly $24 trillion in 2024, reflecting the surge in US national debt.
Foreign central banks and foreign private-sector entities also play a crucial role in absorbing the fast-growing US national debt. Our third FRED graph shows debt held by foreigners (red dotted line), which doubled from about $4 trillion in 2010 to over $8 trillion in 2024. The gold dashed line is total debt held by private investors minus debt held by private foreign investors, which equals debt held by private domestic investors.
More Sources of Debt Data
The US Treasury Bulletin provides a detailed breakdown of public debt holdings among private investors. Those data aren’t currently available in FRED, but FRED does have the Fed’s financial account data, which reports the ownership of total marketable debt. And since most US debt held by the public is marketable, this is a good approximation of public vs. private ownership. Most US debt held by government accounts is non-marketable, as is a relatively small fraction of debt held by the public, primarily through defined benefit pension plans for public sector workers.
You can also check Financial Accounts Table L.210 in FRED for a detailed breakdown of private investor holdings of US debt, including households, banks, insurance companies, public and private pension funds, and mutual funds.
How these graphs were created: First graph: Search FRED for and select “Gross Federal Debt.” Go to the “Edit Graph” section (blue button in the top right) to add the other series: “Federal Debt Held by the Public” and “Federal Debt Held by Agencies and Trusts.” Ensure the units are consistent across the series by using the formula a/1000 to convert millions to billions. Start the graph in 2000-01-01 by using the date entry box above the graph. Second graph: Repeat the process with “Federal Debt Held by the Public,” “Federal Debt Held by Federal Reserve Banks,” “Federal Debt Held by Private Investors.” Third graph: Repeat the process with “Federal Debt Held by Private Investors” and “Federal Debt Held by Foreign and International Investors.” To create the third data series, use the formula a-b for debt held by private domestic investors.
