We came into today with the mindset that the big news of the day would be the FOMC meeting and Chair Powell’s press conference.CPI was certainly on the agenda, but it seemed to be a secondary consideration. Did the CPI report steal Powell’s thunder?This morning’s CPI report was an unmitigated stunner, beating on every measure. The monthly headline and core results were 0.0% and +0.2%, both coming in 0.1% less than consensus expectations. That was obviously great news for both stock and bond investors. By late morning, we see Treasury yields lower by 14-16 basis points, while the S&P 500 (SPX) is up over 1%. The Russell 2000 (RTY) is up just less than 3%, and NYSE advancers lead decliners by about 5:1.This is a powerful, across-the-board rally predicated upon solid economic news.Now what? It was clear that markets expected no chance of a rate change at today’s FOMC meeting, but expectations for a September cut rose from 58% yesterday to 81% now. Two full cuts are now priced in for 2024, up from 1.5 yesterday. It is quite fair to believe that progress toward the Fed’s inflation target would raise the likelihood for cuts, even if we discover later that the Summary of Economic Projections (aka SEP or “dot plot”) was likely to show that two cuts were already expected.We now have to wonder if the markets’ joyful reaction to the CPI report will necessitate a change in tone from Chair Powell. Traders have come to expect a Goldilocks mien from him, if not an outright dovish tone. Even when he tries to be balanced in his approach, traders seize upon the market-friendly portion of his narrative. Today he can’t help but notice the euphoric reaction to CPI; will he want to take a more measured, if not dour, tone to avoid throwing gasoline onto the fire?Either way, we’ve already seen a relatively typical post-FOMC move occur already. As the table below shows, it is normal to see a 1.35% change for SPX on Fed day.I simply don’t have enough data to predict what might occur when we’ve already had a move of that magnitude before the announcement:
