Musk wrote on social media platform X that the Fed, which is responsible for protecting the world's largest economy, is "extremely overstaffed," in a series of discussions sparked by a post about the Fed's latest policy decision. Previously, US President-elect Trump had also targeted the Fed, arguing that he should have a say in monetary policy and interest rate setting. Billionaire Musk, who will be responsible for making the US government more efficient in January next year, is now reportedly targeting the Fed.
