Federal Debt shown here includes Debt held by the Public (not including debt held by Federal Reserve), Debt held in government accounts, and debt held by the Federal Reserve Board (i.e., as part of the monetary base).

Federal Debt was about $8 trillion in the mid 2000s, but the Great Recession of 2007-09 and associated bailouts has helped double the debt in ten years to nearly $20 trillion in 2016.

Viewed as percent of GDP the increase in federal debt is not so startling. But federal debt has still increased from 60 percent of GDP to over 100 percent of GDP in ten years.

US Federal Debt Since 1900

Chart D.13f: Federal Debt in 20th Century

Federal debt began the 20th century at less than 10 percent of GDP. It jerked above 30 percent as a result of World War I and then declined in the 1920s to 16.3 percent by 1929. Federal debt started to increase after the Crash of 1929, and rose above 40 percent in the depths of the Great Depression.

Federal debt exploded during World War II to over 120 percent of GDP, and then began a decline that bottomed out at 32 percent of GDP in 1974. Federal debt almost doubled in the 1980s, reaching 60 percent of GDP in 1990 and peaking at 66 percent of GDP in 1996, before declining to 56 percent in 2001. Federal debt started increasing again in the 2000s, reaching 70 percent of GDP in 2008. Then it exploded in the aftermath of the Crash of 2008, reaching 102 percent of GDP in 2011.

Federal debt has breached 100 percent of GDP twice since 1900: during World War II and in the aftermath of the Crash of 2008.

US Federal Debt since the Founding

Chart D.14f: Federal Debt since the Founding

The United States federal government began with a substantial debt, the cost of the Revolutionary War. Under Alexander Hamilton’s funding system the debt was paid off by 1840. Government debt has typically peaked after wars. It breached 30 percent of GDP after the Revolutionary War, the Civil War, and World War I. It breached 100 percent of GDP in World War II. Government debt also breached 100 percent of GDP in the aftermath of the financial crisis of 2008.

Gross Federal Debt vs. Net Debt

Chart D.15f: Federal Debt Gross and Net

The US federal government differentiates between Gross Debt issued by the US Treasury and Net Debt held by the public. The numbers on Gross Debt are published by the US Treasury here.

Numbers on various categories of federal debt, including Gross Debt, debt held by federal government accounts, debt held by the public, and debt held by the Federal Reserve System, are published every year by the Office of Management and Budget in the Federal Budget in the Historical Tables as Table 7.1 — Federal Debt at the End of the Year. The table starts in 1940. You can find the latest Table 7.1 in here.

The chart above shows three categories of federal debt.

1. Monetized debt (blue), i.e., federal debt bought by the Federal Reserve System

2. Debt held by the federal government (red) e.g., as IOUs for Social Security

3. Other debt (green), i.e., debt in public hands, including foreign governments.
