Federal Reserve Governor Christopher Waller said the central bank needs clear and consistent policy reaction rules so markets can anticipate its decisions, while questioning whether a communications task force will produce significant results. He said a reaction function may be difficult to quantify precisely but remains important as a qualitative guide, and noted that his view of whether such a framework must be perfect differs sharply from that of Fed Chair Kevin Warsh. Waller also argued that surprising markets offers no benefit and that limited disclosure of the likely direction of future policy is preferable to the older "never explain" approach. His comments add to existing disagreement over the review launched by Warsh in June 2026. The task force, led by former Bank of England Governor Mervyn King, former Central Bank of Brazil Governor Arminio Fraga, and Peter Fisher, is expected to recommend changes by the end of 2026. Waller said Fed officials hold strongly differing views on communication, that opposition to scenario analysis was intense last year, and that the outcome of the communications working group remains uncertain. He also said a balance-sheet working group should reject proposals that would return reserves to a scarce condition, urged the data group to use verifiable information to protect trust, and said the inflation working group could be the most useful to the Federal Open Market Committee.
