Investing.com -- Richmond Fed President Tom Barkin painted a picture of an economy that refuses to slow down but also refuses to cool off, telling a Greenville, S.C. audience on Thursday that headline PCE inflation remains at 3.7%, well above the Fed’s 2% target, while declining to signal whether another rate hike is coming in September.

Barkin’s remarks land on a day already heavy with data. July PPI came in flat month-on-month against a 0.2% forecast, a softer-than-expected reading that will feed into the Fed’s preferred PCE gauge. Weekly jobless claims for the period ending August 13 printed at 209,000, above the 202,000 forecast and the prior 200,000 reading, a modest deterioration that, combined with yesterday’s in-line July CPI print of 3.4% year-on-year, leaves markets parsing conflicting signals ahead of the September 15-16 FOMC meeting.

The speech, titled "The Mysterious U.S. Economy," framed the current moment around four puzzles: the economy’s stubborn resilience, a surprising investment boom, persistently low unemployment, and inflation that won’t finish its descent. Barkin’s answer to each leans on behavioral shifts as much as traditional macro mechanics.

On the investment surge, the numbers are striking. Real private nonresidential fixed investment grew at an annualized rate of 9.5% in the first half of 2026, according to Barkin’s Richmond Fed speech, more than double the 5.8% average in the pre-pandemic decade. Artificial intelligence infrastructure is the primary driver, but Barkin stressed the momentum is broadening. "Many business leaders explain they’ve concluded high uncertainty is the new baseline," he said. "They can’t afford to wait any longer." Bank pipelines, mergers and acquisitions, factory construction, and defense spending are all contributing, he added.

The labor market presents its own paradox. July nonfarm payrolls fell by 23,000, yet the unemployment rate held at 4.1%, marking the 58th consecutive month at or below 4.5%, the longest such streak in recorded history, per Bureau of Labor Statistics data cited by Barkin. His explanation: slowing labor demand has been met by equally slowing labor supply, as reduced immigration and an aging population shrink the pool of job-seekers even as hiring stalls.

Consumer resilience, Barkin argued, reflects a post-pandemic "YOLO" mentality. Households are trading down to private-label goods and discount retailers, tapping savings, and cutting insurance coverage, but they are still spending. With the vast majority still employed and wealthier households buoyed by rising home and equity values, overall demand has held up despite real income declines over the past year.

The inflation section was the most closely watched. Barkin acknowledged both sides of the debate without choosing one. The optimistic case holds that today’s elevated readings reflect transitory shocks — tariffs, energy, the AI spending wave — that will fade, aided by modest wage growth and stable inflation expectations. The pessimistic case warns that inflation has been above target long enough to risk embedding itself in firm and consumer expectations, potentially requiring further Fed action. "If the economy is not on a trajectory that will bring inflation back down to 2%," New York Fed President John Williams said in remarks carried by Reuters on August 7, "it would absolutely be appropriate to act."

Barkin did not endorse either view publicly, closing with a deliberate non-answer on the September question. "My custom is to never prejudge the path forward," he said, adding that he plans to keep "collecting clues" from business leaders and incoming data. That non-answer carries more weight than a typical Fed speaker dodge because of a deliberate shift at the top: Fed Chair Kevin Warsh has significantly scaled back forward guidance since taking the post in May 2026, leaving markets with unusually high uncertainty about the September 15-16 decision. In the absence of clear signals from the Chair, every regional Fed voice — including Barkin’s — is being read for directional cues that the committee itself is no longer providing.

The Fed’s July 29 decision to hold the federal funds rate at 3.5%-3.75% was itself unusually fractious: the FOMC voted 9-3, with regional presidents Hammack, Kashkari, and Logan dissenting in favor of a 25-basis-point hike, the largest hawkish dissent bloc since September 2016, according to Crux Investor. Barkin, who does not hold an FOMC vote in 2026, nonetheless carries influence on the committee’s deliberations.

Futures markets trimmed the probability of a September hike to just below 50% after Wednesday’s CPI print, down from above 55% in the days prior, per Reuters. The softer PPI reading Thursday may push that probability lower still, though the trajectory of core PCE, which feeds directly from PPI components, will be the decisive gauge.

Investors will get the next major consumer-spending read on Friday, August 14, when July retail sales are due, with consensus pointing to a 0.1% headline gain. The FOMC minutes from the July meeting, scheduled for release on August 19, will show how broadly the hawkish dissent was debated internally and are likely to be the most consequential near-term input for rate pricing ahead of the September decision.
