Treasury Doubles Bond Buybacks as US Debt Hits $40 Trillion

The United States Department of the Treasury announced on August 19, 2026, that it will double the size of liquidity support buyback operations for 10-year to 30-year nominal coupon securities. Effective from September 9 through November 4, the operations will increase from $2 billion to at least $4 billion per operation. Treasury Secretary Scott Bessent implemented the move to curb long-term yields, which had recently hit 19-year highs above 5.3%, driving up mortgage and loan costs.

While the announcement initially caused 30-year yields to drop to approximately 5.187%, most gains reversed within days as yields climbed back toward 5.25%. Investors expressed skepticism, with some analysts describing the intervention as a temporary fix for a $40 trillion debt burden. Market volatility has been further fueled by massive capital spending on artificial intelligence, geopolitical tensions with Iran, and a divided Federal Reserve. Minutes from a July meeting revealed that while the Federal Open Market Committee held rates steady, three officials dissented in favor of a hike to combat persistent inflation.

In response to the market's resistance, Bessent signaled that buybacks could exceed $4 billion and announced a new fiscal consolidation initiative directed by President Donald Trump. This effort, led by Bessent and Budget Director Russell Vought, may include a fraud task force and cuts to state-level programs. Meanwhile, Federal Reserve Chairman Kevin Warsh has prioritized price stability and indicated a desire to shrink the central bank's bond holdings, creating potential policy tension with the Treasury's efforts to suppress yields.
