US Michigan Inflation Expectations Preliminary (Sep) 4.6% (Prev. 4%)

The Michigan long-run inflation expectations series carries weight well beyond its survey origins: Fed officials have repeatedly flagged it as one of the household gauges they watch for signs of de-anchoring, and on past occasions an upside surprise in this print has been enough to move the front end and prompt comment from policymakers even when harder data were benign. The distinction worth drawing is between the one-year and the five-to-ten-year readings: moves in the short horizon tend to track petrol and salient prices and wash out, while a drift higher in the long horizon is the kind that historically feeds into the reaction function. The usual sequence is that the preliminary print gets the headline attention and the final revision either confirms or fades it, and revisions have on occasion been material. Worth noting that the survey sample and partisan composition have at times distorted this series relative to market-based measures such as breakevens, and the divergence between the two is itself a tell. The follow-ons are the final Michigan release, the next breakeven and inflation swap levels, and whether any Fed speaker picks the print up.
