UK S&P Global Manufacturing PMI Flash (Aug) 51.5 vs. Exp. 51.5 (Prev. 51.9)

An in-line print with a modest downtick from the prior month is the least market-moving configuration a PMI can take: the flash estimate matched consensus exactly, so there is no surprise component to reprice, and the index remains in expansion territory. In past episodes of this kind, sterling and short sterling futures have moved only at the margin on the headline, with any reaction coming from the subcomponents rather than the top line: new orders and export orders as the demand tell, and the input and output price balances as the read-through to the BoE's services-and-wages inflation worry, which is where UK rate pricing has historically been most sensitive. The distinction worth drawing is between the flash and the final print: revisions at the final release are common, and the services survey, given the UK's composition, has tended to carry more weight for the rate path than manufacturing alone. Follow-ons are the companion services and composite flashes the same morning, the final release, and how the pricing subindices feed the hawks-versus-doves balance at the next MPC meeting. As an as-expected release, the signal is continuity rather than a shift in the data trend.
