U.S. Treasury Yields Above 4.5 Percent Raise Debt Service Costs on $35 Trillion Outstanding Debt
Rising Treasury yields reflect the arithmetic of large deficits and shifting buyer composition rather than policy error. Pension and insurance portfolios face valuation losses that scale with duration. Fiscal arithmetic now directly constrains future spending flexibility.
The Federal Reserve's balance sheet runoff continues at $25 billion monthly, removing a price-insensitive buyer. Treasury has signaled larger nominal coupon sizes in the November refunding announcement. Absent legislative action on revenues or entitlements, the structural deficit trajectory points to sustained supply pressure. Markets price a 65 percent probability of a 5 percent 10-year yield by March 2025.
Treasury Department: Net interest payments will exceed $1.1 trillion in fiscal 2025 if the 10-year yield averages above 4.4 percent through September.
