As U.S. Debt Tops $40 Trillion, Debt-Holders Demand Higher Yields
August 24, 2026—One of the most notable effects of soaring U.S. national debt are the rising yields on Treasury’s long-term bond market. Bond investors are simply no longer willing to invest in U.S. long-term debt unless the risk premium on those bonds pay higher yields.
Since July, yields on Treasury’s long-term bonds have steadily risen. The 10-year and 20-year bonds rose climbed above 5.2 and 5.25, up from 4.7 and 4.74 earlier this year. Meanwhile, the 30-year bond rose by 11.49 percent in the past six months, up to 5.23 percent today. When it peaked at 5.30 percent earlier in the month, it was a two-decade high.
That might not seem significant to everyone, but interest rates on long-term debt impact everything from consumer loans on homes, automobiles, and education to government interest payments on the U.S. debt. The yield also reflects the underlying confidence in the U.S. economy and dollar.
Treasury’s Intervention in the Market
Last week, Treasury announced plans buyback larger amounts of U.S. debt itself, increasing the current $2 billion per operation to $4 billion. The next day, the yield rose again, shrugging off the intervention as too little, too late.
Now Treasury is reportedly considering tapping its General Account (TGA), which is the U.S. governments’ primary operating account for paying its bills and funding public services. The account currently hovers just under $1 trillion at $936 billion.
CNBC reported today that two senior Treasury officials have indicated plans to use the General Account to fund bond purchases. CNBC suggested that tapping the account “would not appear to entail any immediate risk.” But it could make keeping a cash balance more challenging. Moreover, it’s unclear if and how the government would reimburse the General Account for those investments.
‘Fiscal Consolidation’
Today, the Financial Times Editorial Board warned about the limits of intervention when consistently high, structural deficits and stubborn inflation are the underlying problems.
“As [Treasury Secretary] Bessent surely knows from his experience with John Major’s government, interventions only work insofar as policymakers have credibility in the eyes of markets,” the FT Editorial Board said.
Asked about the U.S. economy, bond markets, and $40 trillion national debt last week outside the White House, Treasury Secretary Scott Bessent said solutions involved “growing” the U.S. economy out of the hole and implementing “fiscal consolidation.”
That could mean anything from spending cuts, tax increases, or raising revenue through tariffs.
