Understanding the U.S. National Debt: Trends, Projections, and Implications

The federal government is facing significant deficit spending, with projections indicating a substantial increase in the national debt over the next decade. The national debt currently stands at almost $37 trillion and is expected to exceed $52 trillion by the end of fiscal 2035. This debt is significantly larger than the country's GDP, with the debt-to-GDP ratio at 119.4%. The debt has grown in phases corresponding to periods of large federal deficits, such as during the Reagan-Bush years, the 2008 financial crisis, and the COVID-19 pandemic.
Private investors are the largest holders of U.S. debt, owning about two-thirds of the national debt, which amounts to $24.4 trillion. Various federal trust funds and retirement programs, as well as the Federal Reserve System, also hold portions of the debt. Japan is the largest foreign holder of U.S. debt, followed by the United Kingdom and China. Interest on the national debt has surpassed annual spending on Medicare and national defense, reaching $879.9 billion in fiscal 2024, making it the government's third-largest spending area.
The Federal Reserve's policy rate increase in 2022 led to higher borrowing costs for the U.S. government, resulting in a significant increase in net interest on the debt. This shift marked a change from the previous trend of falling interest rates that had helped constrain the government's annual interest costs despite the growing debt load.
