The notes from the Fed’s last meeting (held on July 30–31) included a big reveal: “The vast majority [of Fed members] observed that, if the data continued to come in about as expected, it would likely be appropriate to ease policy at the next meeting.”TP: Keep in mind that the last Fed meeting happened before: 1) the July unemployment rate jumped to 4.3%, 2) July CPI came in lower than expected, and 3) the huge, downward QCEW revisions to jobs growth.
