Inflation in August continued to soften

The headline CPI index in August clocked in 0.27% higher than the previous month, an annualized rate of 3.3%. This is quite a bit lower than the 9%, 7%, 10%, and 5% rates of April through July.

Core CPI, which excludes food and energy, came in at 1.2%. Since the headline number usually follows the core number, this suggests that inflation is likely to head even lower over the next few months.

Compared to 12 months ago, the inflation rate for food was up a bit to 2.9%. That's not outrageous, but it's been rising for the past three months and is starting to get a little peaky. The inflation rate for used cars softened a bit but is still running at an astonishing 32%.

NOTE: Normally I focus on CPI as measured compared to the previous year. However, right now we're in a volatile period and are interested in how inflation is doing right this moment. For that, it's best to look at the increase from the previous month and then multiply by 12 (more or less) to get an annualized rate.

    Refine the talking point: Inflation is up--look at food!!!. Then move the comparison point to the pandemic recession low point for rest of Biden's term.

    The headline CPI index in August clocked in 0.27% higher than the previous month, an annualized rate of 3.3%.

    Not that there is much in the actual "headline" at the link: https://www.bls.gov/news.release/cpi.nr0.htm but the first paragraph reads:

    The Consumer Price Index for All Urban Consumers (CPI-U) increased 0.3 percent in
    August on a seasonally adjusted basis after rising 0.5 percent in July, the U.S.
    Bureau of Labor Statistics reported today. Over the last 12 months, the all items
    index increased 5.3 percent before seasonal adjustment.

    It would seem to offer one at least two or three numbers from which to pick. Which brings to mind:

    Which Kevin seems to have done for the "core" CPI, but then when he talks about food:

    Compared to 12 months ago, the inflation rate for food was up a bit to 2.9%.

    So why doesn't that also get the multiply-by-twelve treatment to become 4.8%?

    Not sure if it will transfer well, but here is the full contents of the first table:

      Multiplying a volatile component's one-month change by 12 would be a poor way to look at the situation. That could be why Kevin didn't do that for food.

    The inflation rate for used cars softened a bit but is still running at an astonishing 32%.

    Still made me wince to read that 32%. I assume the rental car places are finally stocked up and no longer competing with everyone else for cars, but there's persistence supply chain problems with those accursed chips (it's even finally getting to Toyota, who was the most resilient against it for the longest).
