The investigation of the US Department of Justice into Federal Reserve Chairman has recently become a focal point of market attention. This move could trigger ripple effects across multiple asset classes — from US stocks($SPX) to precious metals(Gold$XAU, Silver$XAG) — none of which can remain unaffected. Market participants are generally watching how this investigation unfolds, as the Federal Reserve's policy decisions directly impact the global liquidity environment. Once the Fed's policy stance changes, it often causes fluctuations in the US dollar index, thereby influencing the entire asset allocation landscape. For macro-focused traders, this is a signal worth monitoring closely.
