A fresh reading on the Federal Reserve's preferred inflation gauge released Wednesday showed prices cooled more than expected in August — and is likely to quell some of the urgency for another interest rate hike next month. The Personal Consumption Expenditures (PCE) Index rose 3.4% in August, less than expectations for 3.7% — a level held for much of the summer. Excluding volatile energy and food prices, core PCE rose 3%, beating expectations for a rise of 3.3% and marking a drop from 3.3% in July. Month over month, core PCE inched down a tenth of a percentage point to 0.2% from July and beat expectations of a 0.3% rise.But most of the “drop” from 3.3% is actually due to a recalibration of the PCE index for prices that first took effect today. The Royal Bank of Canada gave an easy-to-understand analysis on the modifications to US PCE inflation. RBC says that the two main sectors that caused that change were: · Portfolio management and investment advice services.
· Computer software and accessories. And the main reason why seems to be related to how the basic unit of these product is determined. For portfolio/investment work, it’s this.
The new methodology replaces the PPI series with a derived price index, obtained through the relationship between nominal and real spending—where real spending is implied by the new quantity extrapolator (i.e., hours worked and aggregate earnings).RBC says that PCE was also having computer software run hot, because there are more units needed than what was previously assumed.
The PCE price index for computer software and accessories has been significantly elevated since November 2025. The average contribution to headline PCE has run strong at 0.12 percentage point between November 2025 and July 2026, unusual for a segment that typically subtracted from inflation prior to 2025. This likely reflects recent demand surges for memory and computing products.Put it together, RBC says it will tamper down the PCE inflation numbers that have been reported for this year by a small amount.
We anticipate an 18-basis-point reduction in the annual pace of core PCE as a result—meaning core PCE in July would be revised down to 3.1% from 3.3%. Importantly, we caution against misinterpreting a lower-than-expected reading on Wednesday as a sign of disinflation ahead.Year-over-year core PCE still dropped in August from that 3.1% to 3.0%, so good sign there. But that’s still well above the alleged 2% target that the Fed wants, and for both core and overall PCE inflation, it’s still not much different than the year-over-year inflation levels we’ve had for most of 2026. And if you look at the PCE energy numbers, this measure already feels irrelevant to where we are today. “Gasoline and other energy goods” rose by 4.4% in August, but was still down 7.8% compared to May, according to the BEA. But we know gas prices have gone up nearly 10% from the end of August and end of September and is now back at May’s highs. So you would think the PCE numbers are headed higher in the next report (which conveniently drops the week before the midterms, after many Americans have voted). And if some of America’s record-high diesel prices are getting passed ahead into other products, that core number will be over 3.0% as well. On the income side, growth was a tepid 0.2%, making for a third straight month of weak increases. However, that report also showed additional evidence of American consumers continuing to spend in August. That increase is spending of 0.8% was significantly higher than the increase in disposable income, as it has for most of 2026. This made for a significant decline in US personal saving of more than $122 billion for August. And yet, the personal savings rate went from less than 3% in July’s report to 4.1%. I saw it, and immediately said "WHAT IS THAT?" Turns out the BEA also used today to release five years of revisions for both national output (GDP and such) and income and spending stats. And it led to a sizable modification for both the income and spending side. For income, there was a significant undercounting of the money that Americans made on interest over the previous three years, in the wake of the Fed raising interest rates in 2022 and 2023 and then keeping them at levels well above the 0% rates of the COVID era. Conversely, income from dividends and income to business owners was overstated from 2023 through 2025, while the original reports of worker income were pretty much on target. The big piece of missing data that we will start to see in the next couple of weeks is whether the spike in gasoline and especially diesel prices started to make American consumers back off of their high-spending ways. Or did they save even less, which should make the Fed more likely to raise rates again to get that Bubbly, inflationary behavior to stop? Also, can American workers get any benefit in wage growth, or will they continue to fall further behind as prices keep going higher? Things kept moving along in August, but this unsustainable pattern has to change some time soon, doesn't it?
