Policy Ambiguity As Market Tool

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 Policy Ambiguity As Market Tool as the practice of avoiding a clear policy defense line so markets cannot easily construct a one-way speculative target. The source derives this from the contrast between the 1992 sterling crisis and Scott Bessent / 贝森特’s later Treasury posture around yen support and Treasury buybacks.

Key Claims

• Clear defense thresholds can invite speculative concentration when fundamentals and policy are inconsistent.
• Sudden intervention, broad toolkits, and unclear reaction functions can make speculative attacks harder to price.
• Ambiguity can buy time but may also reduce democratic and market transparency.
• In the episode, Treasury ambiguity supplements the existing idea of a vague Federal Reserve reaction function.
