Final PMI prints are revisions to an already-published flash, and the market-relevant question in these episodes is whether the revision is large enough to change the read established by the preliminary number. Here the final came in marginally below the consensus, which typically sits close to the flash, but above the prior month, so the direction of travel in the services sector remains upward even as the flash was trimmed. In comparable episodes, small downward revisions of this size have tended to produce only modest sterling and front-end gilt reactions, fading quickly unless they confirm or break a run of revisions in one direction. The transmission channel for UK services specifically runs through the Bank of England's concern with domestically generated inflation, where the survey's price and employment sub-indices have historically carried more weight with policymakers than the headline. The follow-ons are the composite print derived from this release and the detail on input and output prices, which is what the MPC's more hawkish members have pointed to in past cycles when arguing against easing. As a second-tier revision rather than a first look, the signal here is confirmatory.
