Sadly, our feeble attempts at humor were not unjustified, and as any economic history buff knows the US dramatically changed how it calculates consumer inflation back in the 1980s, an event extensively covered by AllianceBernstein former chief economist Joseph Carson on this website in the past (see "Consumer Price Inflation: Facts vs. Fiction") with the most important difference being that while the CPI of the 1970s included house price inflation, the current measure does not. Instead, home price pressures have been swept in the purposefully nebulous Owner-Equivalent Rent which can be whatever politicians wants it to be (there have been other definitional changes, see here, here, here and here for more). Bottom line, however, is that if today's CPI did include house prices in its measurement, the currently reported inflation numbers for house price inflation would push CPI (and core CPI) to double-digit gains.

Of course, it is politically inconvenient to report true inflation is - just see what happens in any banana republic where society is fed up with runaway inflation. It's also why politicians on both sides of the aisle are always eager to tweak the definition of inflation ever so slightly (or not so slightly) so it appears to be less than it truly is. After all, for them masking reality is a matter of political survival.

In any case, what we though this summer was just a joke appears to be coming true, because as the BLS has reported, starting next month it will adjust the weights for its Consumer Price Index basket, which will be calculated "based on consumer expenditure data from 2019-2020." Alas, there is no further detail on this critical topic, although we will take any bet that post-revision reported inflation will drop because, well, "adjustments."
