Core ran hot. Oil is undoing it in real time

Rundown · 2026-09-11

The number came in on the hawkish side of the one-decimal question, and the tape went up. August core CPI rose 0.3% against 0.2% expected; headline was 0.4% m/m and 3.4% y/y, both in line. Gasoline rose 3.9% and accounted for over a third of the entire monthly increase. Every US index future is higher — ES +0.81%, NQ +0.89%, YM +0.88%, RTY +0.86% — VIX is down 4.96% to 17.23, and the dollar has not moved: DXY 99.10, +0.06%. The reason is sitting in the CPI report itself: the thing that made the print hot is the thing that started unwinding overnight.

The Print

Core CPI +0.3% m/m against +0.2% expected, after +0.2% in July. Core y/y fell to 2.4% from 2.5%, as forecast
Headline +0.4% m/m and +3.4% y/y, both matching consensus and unchanged from July's annual rate
Gasoline +3.9% m/m, "accounting for over one third of the monthly all items increase" in the BLS's own words. Energy +2.1% m/m and +16.3% y/y
Fuel oil +10.1% on the month and +52.0% over twelve — the diesel and heating-oil complex is where this shock is most violent, and it is the one that reaches freight
Shelter +0.3% after +0.1% is the number that should worry a hawk more than gasoline, because shelter is sticky and gasoline is not
Against it: medical care and motor vehicle insurance both fell, and core goods rose only 0.1% with used cars +0.4% and new vehicles +0.3%
The three-month annualised core rate is now roughly 2.0% — June 0.0%, July 0.2%, August 0.3%. That is up from the 1.6% reading through July that was the softest of the year, and it is still not an emergency
This is an August reading. Brent above $100, the Saudi output loss and this week's escalation all happened in September and none of it is in this number

The Dollar & FX

DXY is 99.102, up 0.055 (+0.06%). A core print on the hawkish side of consensus moved the dollar six basis points
That is the answer to the question The Open asked at 06:30. We said the dollar had absorbed a hot PPI, an ECB hike and a $5 crude swing without moving, and that the hike was therefore already paid for. It has now absorbed a hot core CPI too. The asymmetry held
The 10-year is 4.943%, unchanged on the day — a yield sitting at a three-year high did not take the print as new information either
Rate-path pricing: the CME-derived probability of a move to 3.75-4.00% at the September 16 meeting stood at 66.7% as of 08:25 ET, against 69.0% the previous day and 50.4% a week ago. That reading is from five minutes before the release — the post-print figure could not be verified at the time of writing, and a hot core would normally push it up rather than down
EUR is 57.6% of the DXY basket, so a European session already trading higher — DAX +0.46%, CAC +0.74%, FTSE +0.77%, Euro Stoxx 50 +0.72% — is doing as much to hold the index still as anything on this side

Energy & Metals

WTI is $99.82, down $2.66 (-2.60%) from Thursday's $102.48 settle, after an overnight range of $98.76 to $104.46. Brent is $104.88, down $2.75 (-2.56%)
Crude has now given back roughly $4.64 of Thursday's $6.43 surge — and it is doing it on a report that Gulf Cooperation Council ministers may meet Iran in Salalah, Oman on Monday, which is still unconfirmed
Hold the two facts together. The CPI that just printed hot was hot *because* of a 3.9% jump in gasoline. Crude is now 2.6% lower than the settle that produced it. The report is a photograph of a month that the market has already started to un-price
Nothing physical has changed. The Strait of Hormuz has been effectively closed since late February and Saudi output fell roughly 1.9 million barrels a day in August. What is moving is the probability the market assigns to that ending
Gold is $4,408.50, up $1.20 (+0.03%), having settled $4,407.30 Thursday and traded as low as about $4,310 earlier this morning. A hot core print and gold is flat
That flatness is the same signal as the dollar's. Gold has spent three sessions trading as a rates instrument rather than a haven. It did not sell off on the print, and it did not rally either — which is what an asset looks like when the news was already in it

Where We Left Off

Dow 52,064.46 (-0.60%) · S&P 500 7,591.79 (-0.58%) · Nasdaq 26,081.72 (-0.65%) · Russell 2000 2,890.95 (-1.04%)
A fourth straight lower close for the S&P, its longest losing streak since June — and this morning's bid is the first serious attempt to end it
The curve made multi-year highs Thursday: 2Y 4.55%, 10Y 4.943%, 30Y 5.35%, the last of those the highest since June 2007. The 10Y has not moved since
Energy was the only sector working Thursday. With crude down 2.6% this morning, that is precisely the exposure that reverses today

Yesterday's Data

PPI +0.4% m/m, 5.4% y/y against 5.3% expected, core PPI 4.6% — the producer-side version of the same energy pass-through CPI just confirmed — full brief
Initial claims 206,000 against 205,000 expected, four-week average turning down for the first time in five weeks — full brief
Existing home sales 3.98M, in line, with supply at 4.9 months, the highest in over a decade — full brief
Crude inventories drew 391,000 barrels against 1.27M expected, but total petroleum built 6.3 million with refineries at 97.8% — full brief

Still To Come Today

The UMich inflation-expectations components are the live one. One-year expectations eased to 4.0% in August and the long-run series has held 3.3% for three months. With gasoline up 27.4% over twelve months, a jump in the one-year number is the most plausible way this morning's calm gets disturbed. The Fed blackout runs through September 17, so nothing official will interpret any of it before the meeting.

Index Movers

ORCL was up more than 5% premarket on Q1 FY2027: cloud infrastructure revenue +121% to $7.4B, total revenue $19.35B (+30%), adjusted EPS $1.92 against $1.74, and remaining performance obligations of $664B. It is a heavyweight in the S&P 500 and Nasdaq 100 and is not in the Dow — most of why NQ leads this morning
The energy majors are the other side. XOM and CVX were supported through Thursday while every index fell. With crude off 2.6%, that support reverses — and because Chevron sits in a price-weighted Dow, energy giving back reaches YM harder than its S&P weight suggests
Fuel-cost names are the cleanest expression of the unwind. RCL carries an 11-session losing streak built almost entirely on crude; the cruise and airline complex led the move down and is the obvious beneficiary if the premium keeps coming out
ADI agreed to acquire Alif Semiconductor for $1.35B all-cash, plus up to $200M contingent, announced Tuesday. Alif makes low-power AI-native microcontrollers for edge inference. Analog Devices is an S&P 500 semiconductor constituent, and this is its second AI-adjacent acquisition this year after Empower Semiconductor at $1.5B. Closing is expected before year-end, subject to Hart-Scott-Rodino

What Would Change The Read

Scoring this morning's call: The Open at 06:30 put the fulcrum on whether core rounded to 0.2% or 0.3%, and said a 0.3% print "with crude where it has been, is very hard to argue against." It printed 0.3%. The framing was right about the number and wrong about the consequence — the market has so far declined to treat it as decisive, because crude stopped cooperating with the hawkish case in the same twelve hours
Watch whether the dollar stays still through the cash open. Six basis points on a hot core print is the strongest evidence available that the hike is fully priced. If DXY is still flat at lunchtime, the September 16 decision is no longer the thing moving this market
Watch whether the Oman meeting gets confirmed. The entire crude reversal rests on a report of a meeting nobody has agreed to. A Saudi refusal or a fresh Houthi strike takes it back, and $104.46 is the overnight reference if that happens
Watch shelter, not gasoline, in the next print. Gasoline is unwinding in front of us. Shelter re-accelerating from 0.1% to 0.3% is the part of this report that does not reverse on a diplomatic headline
Watch the 10-year. Unchanged at 4.943% through a hot core print is a bond market that has already decided. A move above 5% would say it had not

The Bottom Line

The market got the hawkish print it was afraid of and bought stocks anyway, and the explanation is inside the report rather than outside it. Gasoline accounted for more than a third of the August increase, fuel oil is up 52% over twelve months, and the crude that produced both is currently 2.6% below where it settled on Thursday — on a meeting in Oman that has not been agreed and may not happen. What the Fed has in front of it on Tuesday is therefore a photograph of an energy shock taken at its peak, handed over in the week the shock may have begun to reverse. That is an uncomfortable basis for the first hike since 2023, and the dollar's refusal to move six basis points on the news suggests the market has already worked that out. The part of this report that will still be true next month is shelter going from 0.1% to 0.3%, and almost nobody traded it.
