- • Treasury payments to service the $40 trillion national debt surpassed $2 trillion in fiscal 2026, according to the department.
- • CBO scenarios show 150 bp higher rates through 2036 would add $6 trillion to deficits, including $4.9 trillion in net interest costs; a 50 bp increase adds $1.9 trillion, including $1.6 trillion in net interest.
- • Moody's chief economist Mark Zandi warns that rising yields could trigger a self-reinforcing "vicious cycle" as higher interest payments increase debt load.
- • The commentary arrives as the White House presses the Fed, under new chair Kevin Warsh, for lower rates.
Summary
Bank of America analysts Meghan Swiber, Stephen Juneau, Mark Cabana and Ralph Axel estimate that interest expense on U.S. government debt rises by about $95 billion a year for every 100 basis points of Federal Reserve rate hikes. The analysts wrote that while the near-term deficit outlook has changed little, the higher-rate backdrop has altered the longer-run fiscal math, as higher yields compound into greater interest expense and Treasury financing needs over time.
The analysis lands against a backdrop of political pressure on the Federal Open Market Committee. President Donald Trump and his team have argued that rates are too high, citing effects on mortgage affordability, and have previously pressed former Fed chair Jerome Powell, now followed by the FOMC under chairman Kevin Warsh. The article notes that lower policy rates would also reduce the government's own borrowing costs.
According to the Treasury, payments to service the $40 trillion national debt surpassed $2 trillion for fiscal 2026. The Congressional Budget Office, in a recent analysis, modeled two scenarios: rates 150 basis points above current projections from 2026 to 2036 would increase deficits by $6 trillion, including a $4.9 trillion rise in net interest costs, while a 50 basis point increase would add $1.9 trillion to debt projections, including $1.6 trillion in additional net interest.
Mark Zandi, chief economist at Moody's, wrote that global investors appear to be demanding higher yields to compensate for U.S. fiscal risk. He noted the 10-year Treasury yield has risen about a percentage point this year, among the largest increases of any major economy, and warned of a "vicious cycle" in which higher rates raise interest payments and debt load, pushing rates higher still. Bank of America concluded that an unchanged deficit picture is becoming a "bigger financing problem" as elevated yields feed through to the debt stock.
