Weekly Inflation Outlook: CPI May Surprise Higher, but the Fed Won’t

 | Dec 12, 2022 06:10AM ET

  • Core CPI is more likely to surprise to the upside than to the downside on Tuesday
  • Still, save for an outlier inflation reading, the Fed will raise rates by 50bps on Wednesday
  • The equity market is still overvalued for a world in which equilibrium inflation is in the 4%-5% range
  • This week we see both the CPI report on Tuesday and the results of the FOMC meeting on Wednesday. The first thing that should be said is this: those two events are most likely not connected, despite their proximity to each other.

    Chairman Powell has clearly telegraphed that the FOMC will increase the target Fed funds rate by 50bps, and there hasn’t been any significant pushback to that view since then. The next meeting might be in question, but there isn’t a lot of doubt about this one.

    Unless, of course, Core CPI does have a considerable upside surprise. The forecast of 0.3% MoM—which would drop the YoY figure to 6.1%—compares very favorably to the outcomes we have seen over the last year (see numbers below, source BLS).

    • Nov-21: 0.52%
    • Dec-21: 0.56%
    • Jan-22: 0.58%
    • Feb-22: 0.51%
    • Mar-22: 0.32%
    • Apr-22: 0.57%
    • May-22: 0.63%
    • Jun-22: 0.71%
    • Jul-22: 0.31%
    • Aug-22: 0.57%
    • Sep-22: 0.58%
    • Oct-22: 0.27%

    It has been more than a year since we saw consecutive core numbers of 0.3% or below. The last time was between August and September 2021, when COVID categories were still a thing, and the unwind (e.g., airlines, hotels, used cars, plus apparel) drove the core deceleration. But Median CPI accelerated to new month/month highs on both of those occasions, so there was little reason to think the inflation scare was over.

    We have something similar happening here, although in the context of what really does look like a forming peak in inflation. Economists are not calling for 0.3% because there is a general collapse in pricing power. Quite the contrary, in fact: more than half of the inflation basket will still be inflating at faster than 6%-7% annualized.

    The drag is coming from one fairly small category: Health Insurance.

    Last month, CPI for health insurance dropped 4% (about 50% annualized), and the overall Medical Care subindex fell 0.5%. That was a large part of the reason that core inflation was so low. What's more, Health Insurance CPI is essentially a plug number that adjusts for health insurance company profits (which is part of what consumers spend for medical care but doesn't actually go to medical care). It is an adjustment that the BLS calculates annually and smears over 12 months. Ergo, we are pretty confident that there will be another such decline in Health Insurance CPI.

    But what does that mean for the rest of Medical Care? Note that Health Insurance in recent years (but only in recent years) has tended to lead to changes in Medical-CPI-less-Health-Insurance (see chart, source BLS with Enduring Investments calculations). What that tells you is that (since Health Insurance is a residual) there have been some costs that are not well-captured by the surveys of the other parts of medical care. That's not too surprising. Actually...medical care is hard to measure.
