鲍威尔罕见出席美国最高院听证，周三将为美联储理事库克“站台”

Group 1 - The core issue revolves around the independence of the Federal Reserve, with the upcoming Supreme Court hearing on Lisa Cook's case being pivotal for the future of the Fed's autonomy [1][3][4] - The case could set a precedent that allows future presidents to bypass the Federal Reserve Act to dismiss board members, potentially undermining the foundational principles of the Fed's decision-making [4][5] - Powell's attendance at the Supreme Court signifies a defense of institutional rules rather than a personal conflict, highlighting the broader implications for the Federal Reserve's operational integrity [5][7] Group 2 - The legal battle initiated by Trump against Lisa Cook stems from allegations of mortgage fraud, which she denies, and has led to her filing a lawsuit to retain her position [2][3] - UBS analysts suggest that if the government pursues criminal charges against Powell and Senate Republicans block new nominations, Powell may remain in his role as a board member post his chairmanship, potentially continuing to influence monetary policy [2][3] - The outcome of the Cook case will delineate the boundaries of presidential power over the Federal Reserve, which is designed to operate independently from political pressures [3][4]
