July CPI 3.4%: Why September Is Still a Coin Flip

TL;DR

• July CPI rose 0.1% on the month and 3.4% on the year, with core at +0.2% and 2.5%. Every one of those four numbers matched the consensus, and the headline landed within two hundredths of the Cleveland Fed nowcast's 3.42%.
• The feared oil spike did not show up. The energy index fell 1.5% in July, with gasoline down 2.9%, even though energy still sits +14.7% on the year. July was the calm month this site said it would be.
• September pricing barely moved. Hold odds had already drifted from about 60% after the payrolls miss back to roughly 50/50 going into the print as oil rose. An exactly-in-line number gave neither side new evidence.
• The print that actually settles September comes out September 11: the August CPI, the first to carry the post-ceasefire energy shock, lands five days before the FOMC decides on September 16.
• Immediate reaction, pre-market snapshot around 8:45am ET: S&P 500 futures +0.3%, Nasdaq 100 futures +0.7%, dollar index off 0.1%. The record close of 7,757.64 sits 0.4% above Tuesday's finish.

What Does the 3.4% CPI Print Mean for Markets Today?

It takes the September hike off the boil without taking it off the table. Inflation matched the forecast on all four headline lines, so the market kept its coin-flip pricing on the September 16 decision and moved on to what is next: July PPI on Thursday morning, retail sales Friday, and above all the August CPI on September 11, which is the report that carries the oil spike this one did not.

For today's tape that means CPI resolved into a non-event, and Wednesday reverts to the earnings day underneath it: Tencent already out, Brinker this morning, Cisco and Coherent after the close. Futures were modestly higher in the minutes after the release, an early read rather than a session verdict.

The Board

Four lines, four matches. The argument moves to the August print.

What the July CPI Report Showed

The Bureau of Labor Statistics put July CPI at +0.1% month over month and 3.4% year over year, down from June's 3.5% and May's 4.2%. Core, the line the Fed actually reacts to, rose 0.2% on the month and 2.5% on the year, easing from 2.6%.

Inside the print, the war premium and the disinflation story are running in opposite directions at different speeds. Energy fell 1.5% in July, with gasoline down 2.9%, yet the energy index is still up 14.7% over twelve months and gasoline 24.6%. That is the arithmetic residue of the spring oil shock: the level is high, but it stopped climbing for a month. Shelter rose 0.1% on the month and 3.2% on the year, which is the slow-motion improvement doing most of core's work. Food added 0.1%. Airline fares jumped 2.2% on the month and are up 25.5% on the year, the one line still printing like a supply shock.

The scenario map we published Monday worried most about a split print: headline hot on energy, core soft, first hour of trading reading the wrong line. That trap never armed. Headline and core eased together, and there is nothing in this report for the first hour to misread.

Why the Hike Odds Barely Moved

Because an exactly-in-line print settles nothing. The path of September pricing this month tells the story better than any single quote: hike odds near 58% just after the July 29 FOMC, a swing to about 60% hold (65% on Kalshi) after July payrolls fell 23,000, then a drift back to roughly 50/50 by Tuesday as Brent climbed back above $84 on the stalled Strait of Hormuz standoff. This morning's quotes sit within a couple of points of that coin flip, on either side of 50 depending on the source and the minute. I am deliberately not quoting a decimal here; the sources disagree by more than the move.

The committee Warsh chairs held in July with three dissents in favour of a hike, the most since September 2016, and he has stripped forward guidance out of the statements. So the data carries the whole load, and today's data said: nothing you did not already believe. Half the mandate says the labour market is deteriorating. The other half says inflation is 3.4% against a 2% target with a war premium sitting in the pipeline. Both of those things were true at 8:29am and both are true now.

September 11 Is the Print That Decides

The August CPI comes out Friday, September 11 at 8:30am ET, five days before the decision. That is the first report that can carry the post-ceasefire oil spike: the Cleveland Fed's nowcast pencils in a 0.38% monthly jump for August against July's 0.1%, because Brent's recovery above $84 happened inside August's collection window.

So the sequencing going into September 16 runs: PPI tomorrow, retail sales Friday, August payrolls on September 4, then the August CPI on the 11th. My read is that today's print was never capable of settling the meeting, whatever it said. A hot number would have moved pricing hard; the in-line number we got just defers the argument to a report the nowcast already says will look worse on the month. Anyone extending the rally today on "inflation is fixed" is quoting a July number that August is on schedule to contradict.

The counterweight sits at the long end. The 30-year Treasury yield went into this print at 5.23%, near its highest in almost two decades, and that is the market that has refused to relax all year about exactly this: a war-fed price level and a Fed that might blink. Watch whether today's soft print actually pulls the long bond in, or whether the rate-sensitive corners of the tape rally alone.

The Playbook

• The macro gap risk migrated, it did not die. The calendar's next index-mover with real teeth is September 11. Between here and there the tape trades earnings, positioning and oil headlines.
• PPI on Thursday is the confirmation trade. If producer prices echo July's calm, the pause case strengthens into the weekend. If PPI runs hot on goods, it leads consumer prices by a quarter or two, and today's relief was rented.
• The record chase is live again. The S&P 500 starts 0.4% below the August 7 record close of 7,757.64 with the week's biggest risk event now behind it and Cisco's fiscal 2027 AI guide tonight as the next catalyst.
• Oil remains the whole inflation argument. Energy is 14.7% of the year-over-year story and the Hormuz standoff is unresolved. The equity market prices the July calm; the August nowcast prices the spike. One of them is early.

The One-Line Read

July CPI did exactly what the nowcast said it would, which is why the market that spent a week calling this the print of the month spent about ten minutes trading it: the number that decides whether Warsh hikes into a shrinking labour force is the August CPI on September 11, and today's 3.4% is the calm month the oil math said comes before it.
