Fed Vice Chair Philip Jefferson signals officials may want more time before raising rates again, echoing NY Fed's John Williams. Two of the Fed's top leaders are now obliquely casting doubt on an October hike that had been increasingly priced by investors a few days ago.   From Jefferson’s talk: “As we look ahead, my view is that any future adjustments in policy should be determined by carefully examining trends in the data, the evolving outlook, and the balance of risks. Since our September meeting, yields across the term structure have increased further, a sign that investors are reassessing the evolving macroeconomic landscape. My colleagues and I will need to come to our own judgment, which may take more time. I will continue to assess whether underlying trends suggest that inflation will return to target with sufficient speed. With more data in hand, such trends may lend themselves to better discernment, as may the appropriate stance of monetary policy.”
