The September rate hike leg traded at 24.5% on a direct pull of the Polymarket event page at 12:04 UTC on Sunday, August 16. Four sessions before that it printed 43.5%. On Wednesday, August 12 this blog published a piece arguing that hike odds were climbing into the inflation data, and we quoted the leg at 40.5% with momentum behind it. That call is now 16 points underwater, and the market started moving against it within about 24 hours of publication.
Being wrong on direction is the smaller problem. The larger one is that the reason everyone assigned for the move does not survive the order book. Reconstructing the hourly price history puts the single biggest drop on the producer price report of Thursday, August 13, not on the consumer numbers that dominated the coverage the following day.
That distinction changes what a trader should watch into the next set of releases, because it says the market is repricing supply-side inflation rather than demand destruction.
What the Hike Leg Actually Did, Hour by Hour
Daily snapshots are what most desks used, and daily snapshots are what produced the wrong answer. All three reports landed at 12:30 UTC. A price sampled at noon each day therefore captures the previous release's aftermath and credits it to the next one, which shifts every attribution forward by a full day.
Bracketing each release with the hour before and the hour after removes that error. Because prediction markets settle continuously rather than at a daily close, the raw history is available at whatever resolution you ask for. Pulled from the order book at 12:04 UTC on Sunday, August 16, it gives this ranking.
Release (12:30 UTC) | Leg at 12:00 | Leg at 13:00 | One-hour move |
July CPI, Wednesday Aug 12 | 36.5% | 32.5% | Down 4.0 points |
PPI, Thursday Aug 13 | 32.5% | 26.5% | Down 6.0 points |
Retail sales and UMich, Friday Aug 14 | 25.5% | 23.5% | Down 2.0 points |
Measuring by calendar day instead of by release hour changes the size of each move but not the order of the bottom entry. On that basis the CPI session took 7 points, the PPI session took 5, and the retail sales session took 3. Under both methods the consumer data is the smallest of the three, not the largest.
The peak was 43.5%, reached at 19:00 UTC on Monday, August 10 and held into the early hours of Tuesday, August 11. Everything after that was one direction.
Why the Producer Price Print Did the Damage
July CPI came in soft and roughly where the Dow Jones consensus sat. Headline rose 0.1% on the month for 3.4% annual, down from 3.5%, and core rose 0.2% for 2.5% annual, down from 2.6%. Shelter contributed about two thirds of the headline gain at 0.1%, while energy fell 1.5% on the month and remained 14.7% higher than a year earlier.
A print that lands on consensus is already in the price. The hike leg gave up 4 points and stabilised, which is the market removing a tail rather than changing its mind.
The producer data on Thursday, August 13 was the genuine surprise. Final demand came in flat at 0.0% against an expected 0.2%, with services up 0.2% and goods down 0.7%, and the annual rate fell to 4.7% from 5.5%. That 80 basis point drop in a single month is the kind of move that forces a rethink of the pipeline feeding consumer prices two and three months out.
One caution on the core reading, because two different series circulate under the same label and they disagree. Producer prices excluding food and energy rose 0.2%, while producer prices excluding food, energy and trade services rose 0.4%. Quoting one without naming it is how a desk ends up publishing a contradiction against itself.
The leg fell 6 points inside the release hour, briefly touched 26.5%, and settled back to the 27.5% to 28.5% band by the close. That was the largest single-hour repricing of the entire four-session decline.
The Consumer Data Was the Smallest Mover of the Three
Friday, August 14 produced the ugliest headlines and the mildest market reaction, which is a pattern worth internalising.
Retail sales fell 0.6% on the month against a consensus of 0.2% to 0.3%, the steepest drop since May 2025, with the Census Bureau's advance report putting July sales at $763.6 billion and still 5.0% above July 2025. The University of Michigan preliminary sentiment index came in at 51.0 against a 54.5 consensus and 55.2 the prior month, with current conditions at 51.8 and expectations at 50.6. Year-ahead inflation expectations sat at 4.3% and the five-year reading held flat at 3.3%.
The hike leg moved 2 points on it and then recovered one of them by 17:00 UTC.
The reason is straightforward once you separate the two questions a rate decision answers. Weak consumer spending argues against a hike, but the leg had already fallen from 43.5% to the mid-20s by the time the report landed, so most of the repricing was spent. Sentiment surveys also carry a well-earned discount because respondents answer them through the lens of fuel and grocery prices, which is why a 4.3% year-ahead inflation expectation and a collapsing sentiment print can arrive on the same line without contradicting each other.
Positioning had already moved, and the data confirmed it rather than causing it.
Why a Hike Is Still Priced Near One in Four Rather Than Zero
Three soft prints in a row and the market still will not take the hike off the board. The same Sunday pull put no change at 73.5%, a 25 basis point cut at 1.25%, and a 25 basis point hike at 24.5%, on an event that has turned over roughly $33.9 million.
The reason sits in a different index. Core PCE ran 3.3% annually in June against core CPI at 2.5%, with headline PCE at 3.7%. That gap is backwards. Core PCE normally runs two to five tenths below core CPI, mostly because shelter carries roughly double the weight in CPI and because PCE reweights monthly rather than annually. The Cleveland Fed's breakdown of the two indexes covers the mechanics.
Core PCE currently sits about 80 basis points above core CPI, an inversion of the historical relationship rather than a wider version of it. And the Fed targets PCE, not CPI.
So a trader reading only the consumer index sees inflation at 2.5% and near target. The committee reads 3.3% and sees something else entirely. July core PCE publishes at 13:30 UTC on Wednesday, August 26.
The committee itself is split on exactly this point. Rates stand at 3.50% to 3.75% under chair Kevin Warsh, and the July 29 statement records a 9-3 hold with Beth Hammack, Neel Kashkari and Lorie Logan all dissenting in favour of raising by a quarter point. Three dissents in a hawkish direction is not a rounding error, and it is the floor under that 24.5%.
What the Calendar Holds
Minutes from the July 28-29 meeting are scheduled for Wednesday, August 19, and the Jackson Hole symposium runs Friday and Saturday, August 21 and 22. Both land after this piece publishes, so treat everything below as consensus positioning rather than outcome.
The minutes matter mainly for the texture of those three dissents, since consensus expects the discussion to reveal how close the hold actually was. That is the sort of detail the dot plot compresses into a single median and hides. Jackson Hole is where a chair traditionally reframes the policy path without committing to a meeting, and Warsh has not yet delivered one in that setting.
For crypto the transmission runs through the front end. Two-year yields closed Friday, August 14 at 4.17% with the ten-year at 4.68%, while the S&P 500 finished at 7,785.76 after setting a record close of 7,798.99 on Thursday, August 13. Bitcoin traded near $62,940 on the desk's Sunday, August 16 pull, having spent the week moving opposite to equities. Its tendency to sell off around Fed events has been consistent enough that positioning into the September meeting matters more than the decision itself.
Frequently Asked Questions
What are the odds of a Fed rate hike in September 2026?
A 25 basis point increase priced at 24.5% and no change at 73.5% on a 12:04 UTC pull of the September Fed decision market on Sunday, August 16. Cuts are effectively off the board at 1.25% for a quarter point. Search results routinely serve stale figures for this market, so pull the event page rather than trusting a cached number.
Does a weak retail sales report make a rate hike less likely?
Directionally yes, but far less than most traders assume. The July report was the weakest since May 2025 and moved the hike leg only 2 points, because roughly 17 points of repricing had already happened on the two inflation releases before it. Data that confirms an existing move rarely pays.
Why is core PCE higher than core CPI right now?
Because the usual weighting advantage has reversed. CPI weights shelter about twice as heavily, and shelter has been the soft component this cycle, which flatters CPI while PCE picks up firmer services categories elsewhere. It is the single most important reason the Fed sounds more hawkish than the consumer index alone would justify.
What could push September hike odds back up?
A hot core PCE print on Wednesday, August 26 is the cleanest candidate, particularly a reading that holds at or above 3.3%. Hawkish minutes on August 19 would help, though minutes rarely move a leg more than a couple of points on their own.
Bottom Line
The hike leg has three live catalysts before the September meeting and they are not equally weighted. Core PCE on August 26 carries the most, because the 80 basis point inversion against core CPI is the entire reason a quarter of the market still pays for hike protection. Jackson Hole on August 21 and 22 carries the second most, and the minutes on August 19 the least.
Watch the 24.5% level itself. A drift under 20% on the minutes alone would signal the dissent bloc is being priced as isolated rather than as the leading edge, and that is the point where front-end yields start pulling risk assets with them. A hold above 30% into August 26 means the market is positioning for the hawks to win the argument, and Bitcoin has historically not enjoyed that outcome.
The wider lesson from this run is cheaper to learn here than in a position. Attribution windows determine attribution, and a market that has already moved 17 points does not owe you a reaction to the next headline.
