The U.S. national debt has continued its steady climb, surpassing $40 trillion in August 2026 amid persistent annual deficits approaching $2 trillion for fiscal year 2026. Key drivers include mandatory spending on Social Security and Medicare, net interest costs exceeding $1 trillion annually, defense outlays tied to the Iran conflict, and limited offsets from tariffs or spending measures in recent legislation. The debt limit was previously raised to $41.1 trillion, with the next binding constraint projected for late winter to mid-2027. Congressional action remains focused on a continuing resolution through December 2026 and midterm considerations, without enacted changes expected to produce budget surpluses or stabilization by year-end. CBO baselines project debt held by the public rising above 100 percent of GDP and continuing upward through 2036 under current policies.
