Treasury to Double Long-Bond Buybacks to $4 Billion Per Operation

On August 19, 2026, the Treasury said it will double long-bond buybacks to at least $4 billion per operation starting September. The program targets older, less-traded 10- to 30-year bonds as long-end yields surge. The 30-year yield dropped nearly 10 basis points — a tenth of a percentage point — to 5.1942% on the news.
