The US political scene is once again in turmoil. The federal prosecutor's office in Washington, D.C. has launched a criminal investigation into Federal Reserve Chairman Jerome Powell, focusing on his statements and congressional testimony related to a infrastructure renovation project. The project was initially budgeted at $2.5 billion and is now expected to overspend by $700 million. Policymakers are caught in legal turmoil, and markets are always most sensitive to such uncertainties — any change in federal policy direction could reshape the global liquidity landscape and asset allocation strategies.
