US Public Debt Interest Expense Hits Record $1.37 Trillion

The United States has reached a new milestone in its public debt interest expenses, surpassing $1.37 trillion over the past year. This record high comes as no surprise given the rising costs associated with servicing the nation's outstanding Treasury securities. The average marketable-debt interest rate stands at 3.411% as of June 2026, a significant increase from previous years.

This development has major implications for the federal budget, with interest payments potentially surpassing Social Security costs if current trends continue. Market experts suggest that this may put pressure on the Federal Reserve to adjust its rate policy in upcoming meetings.

The Federal Reserve's decision-making process will be closely monitored as they navigate the rising interest expenses and inflation concerns. Observers will watch for statements from Chairman Kevin Warsh and other governors, as well as economic data on inflation, unemployment, and GDP growth.
