The United States national debt has surpassed $37 trillion for the first time, according to the Treasury Department. This milestone was reached less than eight months after the debt hit $36 trillion and marks a rapid acceleration in federal borrowing. The increase follows the signing of the "One Big Beautiful Bill Act" on July 4, which alone added approximately $780 billion to the debt. Since 2020, the national debt has surged by $14 trillion, more than doubling over the last decade. The Congressional Budget Office had projected that the debt would not exceed $37 trillion until after fiscal year 2030, indicating the debt has grown years ahead of expectations. Rising interest costs on this debt are nearing $1 trillion annually and are expected to increase further, raising concerns about fiscal sustainability and the burden on taxpayers. Experts warn that the growing debt may also affect global investor confidence in U.S. Treasury bonds amid potential credit downgrades. The rapid accumulation of debt highlights increasing cost pressures on the U.S. economy and underscores calls for fiscal reform.
