突发特讯！美媒通告全球：美联邦检察官已对美联储主席鲍威尔展开调查，引爆国际舆论

Group 1 - The core issue revolves around a criminal investigation initiated against Federal Reserve Chairman Jerome Powell, linked to a $2.5 billion renovation project, which is seen as part of a broader political conflict between the White House and the Federal Reserve [1][3]. - The investigation was approved shortly after former President Trump publicly criticized Powell for causing significant financial losses, indicating a shift in their relationship from one of nomination to confrontation [3][5]. - The renovation project, initially budgeted at $1.9 billion, escalated to $2.5 billion, which Powell defended as necessary due to aging infrastructure, but the real concern for the White House was the Fed's independence in monetary policy decisions [3][5]. Group 2 - The legal battle has significant implications for the independence of the Federal Reserve, as the investigation could set a precedent for presidential interference in monetary policy [5][7]. - Market reactions to the investigation were immediate, with the dollar index dropping by 1.2% and gold prices soaring to a historical high of $2070 per ounce, reflecting investor anxiety over the Fed's autonomy [5][7]. - Powell's response to the investigation framed it as a test of the rule of law, emphasizing the importance of maintaining the Fed's independence from political pressures, and referencing historical instances of political interference in monetary policy [7][8].
