The U.S. Treasury increased its per-operation cap for note and bond buybacks to $6 billion, effective Sept. 9, 2026, triple the previous $2 billion limit. The first operation under this expanded framework launched Sept. 10 and continues through Nov. 4.
The buybacks target Treasury securities with 10 or more years to maturity. By reducing long-end supply, Treasury aims to support prices and compress yields on the longest part of the curve.
Treasury Secretary Scott Bessent signaled openness to larger buybacks if market conditions warranted the move. The announcement leaves room for future increases beyond $6 billion.
From a duration and spread perspective, the operations inject liquidity into a key institutional market segment. Reduced supply of long-dated paper typically flattens the yield curve as 10-year and longer yields fall relative to short-term rates. The tighter bid-ask spreads in 10-plus-year buckets signal improved market functioning—a critical metric for the $27 trillion Treasury market.
