In early August, the Congressional Budget Office (CBO) released its Monthly Budget Review, indicating concerning trends in the federal budget for fiscal year 2026, which ends on September 30. For the first ten months of this fiscal year, the cost of servicing the national debt surged 14%, rising from $846 billion to $963 billion compared to the same period in fiscal year 2025. This increase is significantly higher than growth rates for other major expenditures, such as Social Security, which rose by 5%, and Medicare and Medicaid, which each increased by 8%.
Notably, the share of interest payments has grown substantially, climbing from 64.9% of Social Security outlays to 70.1% over the past year. This component of federal spending has now emerged as the second-largest expense, after Social Security.
The dramatic rise in interest payments is driven by two primary factors. First, the federal debt has reached approximately $40 trillion, reflecting a 7.3% increase since the beginning of 2026 and a nearly 50% rise since 2019. This accelerating debt trajectory is concerning, with current rates of growth approaching an annualized 15%. Second, rising interest rates have exacerbated borrowing costs, with notable increases in Treasury Note yields over the past year. As deficits expand, the Treasury will require more borrowing, further heightening fiscal pressures.
In response, Treasury Secretary Scott Bessent unveiled a plan to purchase significant quantities of 10-year Treasuries to manage interest rates. By selling shorter-term bonds at lower rates, this strategy aims to recalibrate the average yield of federal borrowing. However, experts view this as a temporary fix that fails to address the underlying issue of escalating government borrowing.
Why this story matters: The rising costs of interest payments on national debt could lead to constraints on government spending in other critical areas.
Key takeaway: The national debt and interest payments are growing at alarming rates, posing a potential threat to fiscal stability.
Opposing viewpoint: Some argue that temporary measures, like Bessent’s strategy, could provide short-term relief without necessitating significant spending cuts or tax increases.
