PREVIEW: US CPI due Wednesday 12th August, 2026 at 13:30BST/08:30EDT
EXPECTATIONS: Headline CPI is expected to rise 0.1% M/M in July, rebounding from the -0.4% decline in June, while the annual rate is expected to ease to 3.4% Y/Y from 3.5%. Core CPI is expected to rise 0.2% M/M (prev. 0.0%), with the annual rate of core inflation seen cooling to 2.5% Y/Y from 2.6%.
PANTHEON MACROECONOMICS: Pantheon argues that the report should be enough to keep the FOMC in wait-and-see mode. The consultancy expects core goods prices to rise 0.18% M/M, which would be the largest increase since September, partly driven by Apple's (AAPL) decision to raise prices across most of its hardware range by 15-30% from June 25th. However, this is expected to be partly offset by softer services components, with airfares seen falling 1.5%, accommodation prices declining 1.0%, and auto insurance premiums expected to continue their recent downward trend. Pantheon also looks for CPI energy goods prices to fall 2.6% M/M in July, subtracting around 11bps from the headline monthly rate, while food-at-home prices are expected to rise a modest 0.2%.
FED IMPLICATIONS: The report will be key in shaping expectations for the September FOMC meeting and updated dot plot. The weak July NFP report prompted participants to pare rate hike expectations, although the subsequent rebound in crude prices has helped push September pricing back towards a coin toss. CPI will therefore provide an important test of whether softer labour market data is enough to keep the Fed sidelined or whether persistent inflation pressures maintain the case for further tightening.
However, July CPI will not be the final major data point before the 16th September FOMC decision. Following this week's inflation reports, policymakers will still receive the August jobs report, August CPI and August PPI before the meeting, while August PCE will not be released until after the FOMC. The September decision therefore remains highly data-dependent, with plenty of scope for expectations to shift between now and the meeting.
The data arguably carries even greater importance given the Fed's continued reluctance to provide explicit forward guidance, leaving markets increasingly focused on incoming releases to gauge the Committee's reaction function. Recent Fed commentary has leaned hawkish, particularly following the July dissents from Kashkari, Hammack and Logan, while non-voters Schmid and Musalem have also said they would have preferred a hike at the meeting. A common argument among the hawks has been that gradual tightening now may reduce the risk of more aggressive action being required later. Conversely, Chair Warsh's acknowledgement that tighter financial conditions are doing some of the Fed's work, alongside the weak July payrolls report and sizeable downward revisions, tempered expectations for near-term tightening.
Overall, a hotter-than-expected core CPI print would likely revive expectations for a September hike, particularly given the recent hawkish Fed commentary and renewed rise in energy prices. Conversely, another soft core reading would strengthen the case for patience following the deterioration in payrolls and could see markets more decisively price out a September move.
Previews of this kind are as much about positioning as about the consensus itself: with rate pricing for the next meeting described as finely balanced, the print sits in the part of the distribution where small surprises in core M/M historically move the front end disproportionately, since a tenth or two either way is enough to flip a near coin-toss meeting. The structural detail worth noting is the composition split flagged by the sell-side: goods-side pressure from tariff or price-reset pass-through running against disinflation in services components such as airfares and shelter-adjacent items, a divergence that has recurred in past cycles and that matters because the committee has tended to discount one-off goods repricing while treating services momentum as the truer signal. The calendar framing is the other established pattern: when a print is not the last major release before the decision, markets have historically repriced on it and then retraced as subsequent labour and inflation data land, so the initial reaction has often proven partial rather than terminal. Dissent-heavy, guidance-light committees amplify single releases, and hawkish dissenters on record lower the bar for a hot print to be treated as committee-relevant. The follow-ons are the subsequent jobs and inflation prints and any shift in tone from the officials named as hawks versus the chair's financial-conditions framing.
