In a significant shift for the U.S. central bank, Kevin Warsh has officially been sworn in as Federal Reserve chair, with President Trump hosting the ceremony. As Warsh takes the reins, he faces immediate challenges, including rising inflation and concerns over the stability of financial markets. While some analysts predict that he may favor interest rate hikes, Trump has suggested he will give Warsh the autonomy to shape policy, despite earlier statements indicating a preference for lower rates. With financial markets reacting to the potential for policy changes, experts note that Warsh will need to navigate a complex economic landscape and restore trust in the Fed amidst these pressures.
