Federal Reserve Governor Christopher Waller said the central bank can wait and see how things develop before making further interest rate moves as financial markets tighten. "The real side of the economy seems to be doing well. The nominal aspect is moving in the direction we hoped. So we're in a position where we can wait and see where rates go, "Waller said Wednesday at the annual E2 Summit in Park City, Utah. "Financial markets are tightening, and that will do some of the work for us," he said.
