Fed funds futures went from 63% positioned for higher rates to roughly even in a single morning, and the number doing most of the work may be a Commerce Department measurement change worth 20 basis points.

Compiled by The InvestorSomething wrong?How this is made
Thirteen points of hike probability came out of the front end across one morning, roughly a fifth of what was priced when the day began [2], and the thing that moved it was a governor's conditional sentence rather than any release [1]. The six basis points in twos [10] is the cheap part of that; the expensive part is that every position built off a 63% consensus [5] is now marked against a coin flip.
The measurement piece is where the arithmetic gets more interesting than the rhetoric. Waller said non-market prices in the PCE basket, the imputed ones inferred from other indicators rather than observed in a transaction, have driven more than half of recent inflation growth [11], and that the Bureau of Economic Analysis change landing at the end of the month could take another 20 basis points off the index [8]. Run that against a 3.05% three-month core rate and you get 2.85%, which closes about 19% of the 1.05-point gap to the committee's 2% goal [3] without one transacted price in the economy behaving differently. Waller's own framing is that ignoring the imputed category, underlying inflation is doing better than the core numbers suggest [19]. The committee, however, answers to a published series, so a definitional change that lowers the print lowers the number the vote is taken against, and whether that counts as disinflation is a question the mandate does not ask.
The conditionality is tighter than the headline reprice implies. He would favour holding at 3.5% to 3.75% if August tracks July [4], he would move to 25 basis points, which is a 3.75% to 4.00% range [4], on a swift uptick [7], and he has already said that if the progress reverses it is time to pull the trigger [14]. He also flagged that the economy could be near a pivot point in which reading trendlines leaves the Fed behind the curve [18]. Meanwhile the assumption carrying the most weight in his stack is the one he spent the least time on: that employment data will not deviate much from what it has been doing [15], with the decision resting on August inflation [13].
That trend is thinner than five months of steady improvement sounds. Going from 4.76% in February to 3.05% in July is 1.71 points across five months, about 34 basis points a month [1], so a single hot core print does not dent the average so much as it ends the story the average was telling.
This is probably wrong, but the tradeable content here is the BEA revision, not the speech, because one governor pre-committing to a data-dependent hold is a vote, not a committee, and the 63/37 split he talked down [5] was never the committee's view either. The counter-thesis is straightforward: he changed tenor once already, since the speech marks a shift from what he was saying in July [17], and a man who quotes John Lennon on giving disinflation a chance [16] can still hike into his own quote a month later. What would prove me wrong is August core printing near the February run rate with the front end climbing back above 63% while the imputation change lands anyway. In that case the redefinition was noise and the trend was the illusion.
Ranked by verification strength, evidence, and original report placement.
Waller said: "Three-month core inflation is 3.05 percent for the three months through July, a level that is still not consistent with the FOMC's 2 percent goal... Three-month inflation has fallen steadily from 4.76 percent in February. That is a considerable improvement, and the speed of this downward trajectory is encouraging."
If inflation readings from August show a similar trajectory, Waller said he would favor keeping the federal funds rate at its current range, between 3.5% and 3.75%.
Coming into Thursday, federal funds futures contracts tracked by CME Group showed 63% of market participants expecting higher rates and 37% anticipating no change; after Waller's speech the split moved closer to 50-50.
Waller noted his stance was not definitive, saying a swift uptick in inflation could make him favor a 25 basis point increase.
The Commerce Department's Bureau of Economic Analysis is set to adjust how it measures non-market prices, a change Waller said could shave an additional 20 basis points off the inflation index, expected to take effect at the end of the month.
Waller said his decision on the appropriate stance of policy will be heavily influenced by what the Fed learns about August inflation.

Evidence-backed comparisons of source perspectives and observed adoption signals. Read the methodology
Which Builder, Operator, and Investor concerns the observed source mix emphasized—not a truth score.
Evidence, demonstrated adoption, hype gap, incentives, and confidence are assessed independently, each on its own current evidence. How these are measured.
One speech, generously quoted, nobody else in the room
The quotations are long enough to judge Waller in his own words, and the market data carries a named source in CME Group. What is missing is everything outside the speech: no BEA notice behind the 20 basis point revision, no second FOMC voice, no transcript link, and a July comparison whose supporting sentence trails off unfinished. Strong on what was said, thin on whether any of it checks out.
Priced for a morning, not committed to
Markets did respond, and measurably: about a fifth of the priced hike expectation came off and the two-year gave up six basis points inside the speech. But that is one morning's repricing to roughly even odds — the market moved from leaning one way to not knowing, which is agreement to wait rather than agreement with Waller. The actual test, an August inflation print, has not happened in this reporting.
Sharper arithmetic than the source will bear
Our framing puts the measurement change at the center — the number 'doing most of the work' — but Waller offered it as one factor alongside a five-month disinflation trend, and nothing here links the futures move to the revision at all. The '13 points' is likewise subtraction performed on the phrase 'closer to 50-50.' The direction of both readings is right; the precision is borrowed.
The analyst is also the voter
Waller is not commenting on the rate decision, he is casting a vote in it, and his analytical moves both point the same way: discount the imputed prices that drove more than half of recent inflation, then credit a coming statistical revision worth 20 basis points. That may be correct — it is also exactly the arithmetic a governor who wants to hold would need. He is the only voice in this reporting, delivered to a banking readership with a direct stake in the answer.
Trust the direction, discount the decimals
What Waller said, and that rates markets moved while he said it, we would stand behind. The two figures readers will actually carry away — a 13-point drop in hike odds and 20 basis points of statistical relief — are one rounding and one unverified forecast. A BEA release note or a second account of the speech would move this well up.
