Fed Chair Powell has raised concerns about a criminal investigation being pursued by the Justice Department, warning that such action could undermine the Federal Reserve's institutional independence. The potential intervention in central banking operations represents a significant development for financial markets, as the Fed's autonomy in policy-making is considered critical to effective monetary governance. This situation reflects broader tensions around regulatory oversight and the degree of political influence on key financial institutions. Market participants are closely watching how this situation evolves, given the implications for future monetary policy decisions and broader economic stability.
