Atlanta Fed GDPNow (Q3) 3.3% (prev. 3.4%)

GDPNow is a modelled running estimate, not an official release, and small revisions of this size between updates are routine; the model has a track record of converging on the eventual print only late in the quarter, and of carrying a wider error band around turns and around quarters with large net-export or inventory swings. A downtick of a tenth within an already-above-trend estimate typically moves the front end and the dollar only at the margin, since it neither changes the growth narrative nor touches the inflation inputs that dominate the policy reaction function. What has historically repriced rates off this series is a sequence of same-direction revisions that takes the estimate across a psychologically salient threshold, or a sharp divergence from other tracking estimates, rather than any single update. The relevant follow-ons are the source data feeding the next revision, particularly consumption, trade and inventories, where most of the model's tracking error has historically sat, and how the nowcast sits against consensus for the official advance estimate as the release approaches. The signal here is one of marginal softening within an otherwise firm read.
