Dallas Federal Reserve President Lorie Logan on Friday said it's not clear if monetary policy is tight enough to bring inflation down to the U.S. central bank's 2% goal, and it is too soon to be cutting interest rates. There are still good reasons that inflation will return to the Fed's 2% goal in the coming years, Logan told the Louisiana Bankers Association's annual conference. "There are also important upside risks to inflation that are on my mind, and I think there's also uncertainties about how restrictive policy is and whether it's sufficiently restrictive to keep us on this path."
