Treasury Buyback Policy

179.先救日元再救长债，“救火队长”贝森特在走一条怎样的钢丝？ adds Treasury Buyback Policy as a Treasury-market tool whose meaning is both technical and macro-signaling. The source says Treasury increased single-operation buyback limits for 10-to-30-year old bonds for the September 9 to November 4, 2026 window, while long-end yields were near high levels, and reads the action as a signal of concern about long-end financing pressure.

Key Claims

• Officially, buybacks can improve liquidity in older, less-traded Treasury securities.
• In the episode’s reading, buybacks also reveal a Treasury reaction function around long-end yields and market absorption.
• The short-term market response may fade because buybacks do not erase debt supply or create new global savings.
• Buybacks can help dealers and off-the-run liquidity but are not equivalent to a full yield-control policy.
