Rising Treasury yields could force US interest costs to $2.5 trillion by 2036, consuming 30% of revenue as the government refinances $39 trillion in debt.

Recent surges in long-term Treasury yields have eliminated the United States' margin for error regarding its fiscal stability, with the national debt standing at $39 trillion [1]. Rates on 30-year bonds recently hit 5.2%, the highest level in 19 years, while the benchmark 10-year yield reached 4.7%, a peak not seen since 2007 [1]. Analysts warn that if these elevated yields persist, federal interest expenses could crowd out funding for essential programs like Social Security and Medicare [1].

**Key takeaways**
*   Interest costs could rise to $2.5 trillion by 2036, consuming 30% of federal revenue [1].
*   The federal government must borrow almost $10 trillion in the next 12 months [1].
*   Current annual interest expense is nearly $1 trillion, exceeding Medicare spending [1].
*   Federal Reserve Chair Kevin Warsh is cited as favoring monetary tightening to cool demand [1].

## Projected costs exceed government forecasts
The Congressional Budget Office (CBO) forecasts that 30-year and 10-year Treasury yields will average 4.65% and 4.15% respectively through fiscal year 2036, roughly 55 basis points below the peaks seen in late May [1]. However, the Committee for a Responsible Federal Budget projects that if yields remain at those higher levels, interest costs could jump to $2.5 trillion by 2036, absorbing 30% of all federal revenues [1]. This would make interest the second largest budget category, surpassing Medicare spending, with the cost per household soaring from $7,900 to $17,000 over the decade [1]. Yields did dip slightly in late May following reports that the Iran War might end, but they remain elevated above forecasts [1].

## A costly refinancing burden
The government faces an immediate need to borrow nearly $10 trillion over the next 12 months to repay maturing securities and cover budget deficits [1]. This situation is compared to the "teaser" rate mortgage crisis,
