We finally got our first “regular” CPI report since September this morning. Caution is still warranted, however, because the October-November kludge is still present in the base from which December’s monthly change was calculated. But the bottom line is that the series’ all reverted to their pre-shutdown trend, with the headline number up 0.3% and core inflation up 0.2%, but also with the shelter kludge still affecting the headline YoY comparisons of 2.7% and 2.6% respectively.
As per my usual practice for the past several years, let’s start with the YoY numbers for headline inflation (blue), core inflation (red), and inflation ex shelter (gold), which was only up 2.4%:
The good news is that CPI less shelter decreased -0.2% in December, and CPI ex shelter was the lowest since July, suggestion significant *disinflation.* Notably the previous uptrend in non-shelter inflation and a smaller but notable increase in headline inflation, with no deceleration in the past 12 months flat YoY core inflation, was clearly broken by the shutdown kludge. If shelter had increased its previous 0.3% monthly during those two months, both headline and core consumer inflation would be over 3%.
Nevertheless, shelter inflation has decelerated YoY per the latest measure, down to a 3.2% increase, with rent up 2.9% and Owner’s Equivalent Rent up 3.2%, the lowest increase since September 2021 except for last month’s kludge:

As usual let’s compare that with the YoY% changes in the repeat home sales indexes, which lead by about 12-18 months (/2.5 for scale), to CPI for shelter (red). YoY home price increases are near or at multi-year lows, each at roughly 1.5%, and shelter inflation has followed. The graph linked to below includes several years before Covid to show that this is well within its 3.2%-3.6% range during the latter part of the last expansion:
Another bright spot is that gas prices declined -0.5% for the month, resulting in a -3.4% YoY decline, which is welcome news to consumers:

Let’s take a look at a few other areas of interest.
First, new car prices continue to be largely unchanged, flat for the month and up only 0.3% YoY, while used car prices reversed their shutdown increase, declining -1.1% in December and up only 1.6% YoY. The graph linked to below shows the post-pandemic trend by norming both series to 100 as of just before the pandemic:
Every month I check the detailed breakout for “problem children,” I.e., sectors that have increased in price by 4% or more YoY. This month included several minor irritants including non-alcoholic beverages and tobacco, as well as fuel oil. Another recent problem child for inflation has been transportation services, mainly vehicle parts and repairs as well as insurance. Of these, only repairs and maintenance are still problematic, as while declining -1.3% for the month, they remain higher YoY by 5.4%:
Finally, electricity prices have also become a significant problem, likely a side effect of the building of massive data centers for AI generation. These declined -0.1% in December, but on a YoY basis are up 6.7%, the highest increase since 2008 except for the shutdown kludge and the immediate post-pandemic inflation:
As I wrote last month, this has already created a backlash, and I expect that backlash to intensify.
In summary, on a monthly basis December consumer inflation was relatively tame, with shelter cost increases slowly abating and only a few other problem children. I would continue to treat both headline and core YOY numbers with extra caution, since they both remain affected by the situation with shutdown shelter kludge. More likely YoY inflation is roughly steady in the 3% range, above the Fed’s target and with employment growth dead in the water.
