Core CPI, which excludes food and energy, is expected at 0.2% m/m against 0.3% in August. This is the number that decides the week.
0.2% monthly compounds to 2.43% annualized, which is essentially at target. RBC expects exactly that - a more modest +0.2% m/m - and reads the annual rate's nudge higher as arithmetic rather than acceleration. The consensus, in other words, is that an energy shock large enough to put the headline at 3.6% has not yet reached anything that is not energy.
The hawkish scenario is 0.3% or 0.4%. That is the print that converts an energy shock into an inflation problem, because it means pass-through has reached airfares, freight, insurance and the service categories where crude arrives on a lag of months rather than days. It is also the only plausible print this week that makes 27-28 October live again - MUFG is explicit that core must surprise to revive an October hike - and it would hand the four participants who wanted two more hikes their evidence eleven days before the meeting.
The dovish scenario is 0.1%. Combined with a 0.6% headline it would describe the cleanest possible version of a supply shock: large, concentrated and contained. It would also strengthen the case the minutes show Vice Chair Jefferson and President Williams making, that waiting for more data costs little. December's 74.5% is where that would register.
It is worth stating plainly what the consensus implies, because it is a strange pair of numbers. The street wants a 0.6% headline and a 0.2% core in the same report - a 7.4% annualized top line and a 2.4% annualized underlying rate, in the same economy, in the same month. Both have been roughly true for three months. The genuine risk this week is not that one of them is wrong, but that the gap between them finally begins to close from the wrong end.
