Odaily Planet Daily News: Fed's Williams said on Friday that uncertainty is high and will continue to exist for some time to come. "We are going through a moment of uncertainty and change," Williams said. "There is no doubt that uncertainty will continue to be the defining feature of the monetary policy landscape for the foreseeable future," Williams said. "This is a direct result of structural changes in the global economic environment, such as changes brought about by artificial intelligence, deglobalization, and innovation in the financial system." Williams did not comment on the economic outlook or monetary policy. He also said that the independence of the central bank can bring better results. (Jinshi)
