#USNationalDebt The national debt of the United States is the total that the federal government owes to the holders of Treasury securities. As of March 2025, the total debt exceeds $36.5 trillion, with approximately $29 trillion in the hands of the public and $7.4 trillion in government accounts. This debt has increased significantly due to spending on social programs, military expenditures, and responses to crises such as the COVID-19 pandemic. The debt-to-GDP ratio has reached historic levels, exceeding 100%, raising concerns about long-term fiscal sustainability.
