The relationships between political leaders and financial institutions are going through a phase of great tension. Donald Trump, the President of the United States, has strongly criticized the Federal Reserve (Fed) and is calling for an immediate reduction in interest rates. This appeal, made during the World Economic Forum in Davos, comes at a time when the Fed, led by Jerome Powell, is maintaining a cautious approach in the face of persistent inflation and a strong labor market. Such a showdown highlights critical stakes for the American economy, raising questions about the independence of central banks on a global scale.
