US PCE Prices Adv (Q3 QQ) 2.1% vs. Exp. 3.4% (Prev. 5%)

This is the quarterly PCE price index embedded in the advance GDP report, not the monthly PCE deflator that anchors the Fed's target measure, though the two are strongly correlated and a miss of this size tends to be read straight through to the preferred gauge. A print this far below consensus is a large surprise by the standards of advance GDP components, and the usual sequence is an immediate bid in the front end and belly, a softer dollar, and pressure on yields concentrated in the real-rates leg if the growth line holds up, or in breakevens if the soft inflation print arrives alongside weak activity. The key distinction is between a benign disinflation signal, where growth is intact and the inflation components fall, and a demand-collapse signal, where both roll over together; the market reaction in rates is similar at first but the equity and credit follow-through diverges sharply between the two. Worth noting that advance prints carry the widest revision risk in the GDP cycle, and the accompanying core PCE line and the monthly deflator due shortly after are where the signal gets confirmed or faded. The watch items are the composition of the price slowdown, goods versus services, and how Fed speakers characterise the print relative to the path they have already signalled.
