Even If M/M Inflation Remains Flat, Y/Y Will Remain Elevated

US DATA

The CPI report for April is certain to scramble analyst forecasts for 2021 inflation. As we await this week's sell-side reviews for any forecast amendments, a thought experiment: even if each M/M CPI print is 0.0% in every month between now and the end of the year, we still won't have another headline Y/Y print below 2.0% in 2021 (see chart).

  • While of course this is just a stylized scenario - perhaps we will get negative M/M readings as some of the extreme subcategory outliers in recent months reverse - it illustrates the extent to which base effects are crucial, and how much the April shocker bumped up the baseline. And if we get another strong month or two in May and June, the impact is only amplified.
  • If CPI in April had seen the expected 0.2% M/M increase instead of the 0.8% actual, for example, then a 0.0% straight-line forecast would have brought headline Y/Y below 2.0% as soon as September 2021 (vs Jan 2022).
