On Friday's broadcast of CNBC's "The Exchange," International Monetary Fund Managing Director Kristalina Georgieva discussed the IMF's newest report on the U.S. economy and stated that "inflation is stubborn, it is way too high," which "means that the Fed will have to keep interest rates higher for longer, all the way into 2024" and "interest rates around 5.25 to 5.5%" will be needed to get inflation on the right track.
