Regarding the issue of the Federal Reserve FOMC Chairperson selection, the shadow chair system, while theoretically possible at the rule level, has a very limited probability of actual implementation. The fundamental reason is that once a shadow chair scenario truly occurs, it essentially signifies a direct confrontation between the Federal Reserve and the current administration, a power struggle that the vast majority of Federal Reserve governors would want to avoid. From an institutional design perspective, although the Federal Reserve's independence is protected within the constitutional framework, maintaining a delicate balance in political reality remains necessary. If the FOMC Chairperson selection issue ultimately escalates into an open power struggle, regardless of which side wins, it could undermine the credibility of the Federal Reserve's institutional framework, posing risks to long-term monetary policy implementation. Therefore, while the possibility of a power struggle exists in theory, stakeholders are more inclined to negotiate behind the scenes to reach a consensus.
