The US will add $5.5 trillion to national debt by 2034 under the One Big Beautiful Bill Act, the Committee for a Responsible Federal Budget projects.

Social Security's retirement trust fund will declare bankruptcy in 2032, triggering automatic 24% benefit cuts across all recipients. Retirees would lose $18,400 annually in combined benefits, creating a welfare shock unseen in advanced economies since Greece's 2010 pension crisis.
Medicare trust funds face insolvency between 2032-2035, requiring benefit cuts, tax increases, or additional borrowing. Fewer than 24% of current Social Security recipients will see tax relief under the new law, the Center for Budget and Policy Priorities reports.
Federal Reserve Chair Jerome Powell's term expires May 2026, adding monetary policy uncertainty during fiscal expansion.
