[Wharton School economist: If Powell does not cut interest rates significantly, the US economy may "rush towards the cliff"] Golden Finance reported that Jeremy Siegel, a professor at the Wharton School known as the "Godfather of the Stock Market", recently wrote that the Federal Reserve should consider a larger interest rate cut, otherwise it will face the risk of economic recession. In the article, Siegel believes that most economic models show that Powell should choose the federal funds rate level that best suits economic conditions, rather than focusing on the speed of interest rate cuts from a very restrictive level.
