Meanwhile, in economic news, Federal Reserve Governor Lisa Cook said Wednesday at the University of Virginia that the path of interest-rate reductions will continue to be based on incoming data and information and can be adjusted faster or slower depending on conditions.

"I still see the direction of the appropriate policy rate path to be downward, but the magnitude and timing of rate cuts will depend on incoming data, the evolving outlook, and the balance of risks," Cook said. "I do not view policy as being on a preset course, and I am ready to respond to a changing outlook. In fact, I find it helpful to consider a range of scenarios when thinking about the path of policy."
