• Core CPI has settled into a pattern of overly hot readings
  • Core services inflation remains hot, core goods disinflation waned
  • Little but volatile market reaction
  • Key is how this may translate into the Fed’s preferred inflation gauge

 

  • US headline/core CPI m/m %, SA, December:
  • Actual: 0.3 / 0.3
  • Scotia: 0.3 / 0.3
  • Consensus: 0.2 / 0.3
  • Prior: 0.1 / 0.3

US core CPI confirmed expectations that underlying inflationary pressures in the US economy remain too hot for the Fed’s liking which leans against market pricing for a cut as soon as the March meeting. The underlying details (here) reinforced this takeaway and I’ll point out what met expectations and where there were surprises. The USD is slightly firmer post-release. Yields were marginally affected albeit volatile thus far. Stocks are flat.

Core inflation (ex-food and energy) landed at 0.31% m/m SA with headline CPI up by 0.3% m/m SA. Both readings met my expectations while core met consensus, but headline was a tick firmer than consensus.

Headline and core CPI matched one another because gasoline and food did not offer material weighted contributions which was in line with what I had estimated. Food was up by just 0.2% m/m and so the 13.4% basket weight translated into no contribution. Gas was up by 0.2% m/m SA and so the 3.2% basket weight translated into zero weighted contribution as expected.

Have a look at the pattern of late when m/m core readings are annualized in chart 1. The latest December reading of 3.4% follows the 3.9% print in November. The 2.8% estimate for October was the lightest reading in the past five months as the prior two months settled in at 3.5% and 3.8%.

In other words, the trend continues to point to readings that are too hot for the Fed’s liking by way of the data dependency part of how they formulate policy. Expectations are the other part, but Chair Powell will remain skeptical toward what Fed models are predicting given the disastrous performance of inflation models throughout the pandemic and his comments on their track record. Powell will retain a show-me-the-proof bias and until he gets convincing evidence that underlying inflation is settling in toward 2%. Until he sees such evidence that that it is staying there I just don’t think he’s going to seriously entertain cutting along the market’s timeline.

Core goods CPI (ex-food and energy) was flat at 0% m/m SA which is the first non-negative reading in four months as shown in chart 2. I think core goods disinflation is waning but was a little surprised to see it in this report. This is part of what drove the firm overall core CPI reading. It’s just one month, but the evidence tentatively leans toward viewing core goods disinflation as maturing. More data is clearly needed.

Core services CPI ex-housing and ex-energy was up 0.4% m/m for the second consecutive month which was in the realm of what was expected. Given the pattern to date, this portrays the deceleration to 0.2% in October as the aberration (chart 3).

Across other details, housing was a significant contributor once more. Owners’ equivalent rent was up 0.5% m/m which continues to be hot. Rent of primary residence was up another 0.4% m/m SA and is also hot.

New vehicle prices were up by 0.3% m/m SA which was in the ballpark of industry guidance, but I’m a bit surprised by used vehicles relative to industry guidance as they were up 0.5% m/m.

The accompanying table at the back of this publication provides further details including micro-charts and z-score measures of deviations from trends.

As for next steps, the Fed’s preferred measure of inflation is the price deflator for total consumption, or the PCE measures that arrive on January 26th. That is five days before the January FOMC. The core PCE measure has been undershooting core CPI with 0.1% m/m SA prints in October and November. The Cleveland Fed’s ‘nowcast’ for core PCE suggests this could end with the December reading, although it can be off in either direction.
