Oil Above $100 And Hot August CPI Sharply Raise Odds Of Fed Rate Hike
On Friday, September 11, 2026, a hotter-than-expected August Consumer Price Index and oil trading above $100 per barrel sharply boosted markets' odds of a Federal Reserve rate hike at the Sept. 16 meeting.[1]
The Labor Department reported August CPI rose 3.4% year-over-year and 0.4% month-over-month, with core CPI up 2.4% year-over-year and 0.3% on the month.[2] After the release, CME FedWatch showed the implied probability of a rate increase next week jumped to nearly 90%, and several forecasters moved to expect a 25-basis-point hike.[1]
On February 28, 2026, U.S. and Israeli strikes on Iran set off a conflict that sharply reduced crude flows through the Strait of Hormuz and tightened global oil supply.[3] Houthi attacks on Red Sea routes, Ukrainian strikes on Russian refineries and high U.S. refinery utilization have compounded the refined-fuel squeeze, sending diesel above $6 per gallon and gasoline to roughly $4.30 nationally.[4][5]
The supply shock prompted the Energy Information Administration to raise its 2027 diesel outlook and warn inventories will sit near five-year lows, while major banks and analysts have lifted price forecasts and flagged a material chance Brent stays above $100 for months.[6][7] Earlier in the week some officials and futures prices suggested a seasonal easing, but later research notes and market moves have shifted expectations toward prolonged higher prices and faster Fed action.[3]

- U.S. diesel hit record levels above $6 per gallon in early September 2026 — AAA reported a national average diesel price of about $6.06 on Friday, September 11, 2026 — intensifying concerns about higher transport and goods costs (AAA national average diesel price).
- The national average gasoline price climbed to roughly $4.29–$4.30 per gallon in mid‑September 2026, more than $1 higher than a year earlier and above prior Labor Day records, contributing to rising consumer price pressures (national average gasoline price).
- The Labor Department reported the August 2026 Consumer Price Index rose 3.4% year‑over‑year (0.4% month‑over‑month), with core CPI up 2.4% year‑over‑year and a 0.3% monthly increase — readings that were slightly hotter than expectations and showed a recent pickup in underlying inflation (August Consumer Price Index).
- Markets and economists reacted sharply: CME FedWatch-implied odds of a Fed rate increase at the September 16, 2026 meeting jumped to nearly 90% after the August CPI release, and several forecasters shifted to expect a 25‑basis‑point hike next week (CME FedWatch data).
- Analysts and reports attribute the price surge primarily to the February 2026 U.S.–Iran conflict and reduced crude flows through the Strait of Hormuz, compounded by stepped‑up Houthi attacks on Red Sea routes and strikes on foreign refineries that have tightened refined‑product supplies (Strait of Hormuz).
- The Energy Information Administration raised its diesel outlook on September 9, 2026 — boosting its 2027 U.S. retail diesel forecast by 33 cents and its 2026 projection by 22 cents — and now expects U.S. distillate inventories to fall below 100 million barrels in September and remain near five‑year lows into 2027 (EIA).
- Major banks and energy analysts warn of a prolonged price upside: Goldman Sachs said Brent could reach $120 with worsening Middle East attacks and options markets imply a materially higher chance of prolonged $100+ oil, Bank of America raised its second‑half 2026 forecast and outlined $95–$120 (and higher) risk scenarios, and S&P Global now sees Middle East output not returning to prewar levels by end‑2027 — while a Brown University tracker estimates Americans paid about $100 billion more for fuel since the war began (Goldman Sachs).

Energy Department raises 2027 diesel price outlook by 33 cents amid Iran war
New information:
- On Wednesday, September 9, 2026, the Energy Department's Energy Information Administration raised its 2027 U.S. retail diesel price forecast to an average of $4.40 per gallon, up 33 cents, or 8.2%, from its prior $4.07 estimate.
- In the same September 9, 2026 update, EIA increased its 2026 U.S. retail diesel forecast by 22 cents to $5.07 per gallon.
- EIA now projects U.S. distillate fuel oil inventories will drop below 100 million barrels in September 2026 and remain below the 2021–2025 five-year low through much of 2027, citing supply losses from the Middle East, Russia and China plus high U.S. net exports.
- The outlook assumes global distillate production will stay below last year's levels in coming months and that refinery maintenance this fall and winter will constrain U.S. output just as agricultural and heating demand rises.
- EIA notes that before the Iran war it had expected 2027 diesel to average $3.47 per gallon, 93 cents lower than its latest projection, underscoring the conflict's effect on forward price expectations.
- Despite the higher retail price outlook, EIA forecasts diesel crack spreads and refining margins will gradually decline through mid-2027, based partly on an assumed near-term normalization of tanker traffic through the Strait of Hormuz and increased distillate exports from Saudi and Kuwaiti refineries.
- President Trump said on September 9, 2026, that he expects oil prices to start "tumbling downward" after the November midterm elections and predicted U.S. gasoline could fall below $2 a gallon, while acknowledging that the decline may take "a little bit longer than the midterms."

- The article notes U.S. diesel averaged $5.94 per gallon overnight, 9 cents above Friday and at a new all‑time high.
- The AP reports that jet fuel prices have risen enough that U.S. and international airlines have already cut flights and raised fares and fees in response.
- Bank of America’s latest research note, quoted in the piece, raises its second‑half 2026 oil forecast to $83 per barrel because of persistent disruptions to the Strait of Hormuz and outlines scenario ranges of $95–$120 if attacks maintain a chokehold on traffic, and up to $150 in the event of major infrastructure damage.
- The article adds negotiation detail that U.S.–Iran talks over a preliminary deal to end the conflict broke down specifically over control of the Strait of Hormuz, including Iran’s insistence on charging passage fees and the U.S. use of a Navy blockade to keep the strait open without such terms.
- It underscores that stepped‑up Houthi attacks on Saudi facilities are constraining the alternate Red Sea route Saudi Arabia has relied on to move oil during the war, compounding the Strait of Hormuz disruption.

Goldman Sachs warns oil prices could hit $120 as U.S. fuel costs surge
New information:
- Goldman Sachs' Sept. 7, 2026 research note warned that worsening Middle East attacks could push Brent crude oil above $120 per barrel, about 20% higher than its level near $100 at the time, which would further add to elevated U.S. fuel prices.
- The bank raised its base-case year-end forecast for Brent from $80 to $85 per barrel and for West Texas Intermediate from $75 to about $80 per barrel, citing modest inventory draws and an expected gradual recovery in Middle East oil shipments.
- The article reports that on Tuesday, September 8, 2026, Brent briefly rose to $99.46 per barrel before dipping to $97.85, up from roughly $72 two months earlier as fighting in the region dimmed prospects of reopening the Strait of Hormuz.

- AAA data cited in the story show diesel reached a U.S. record of $5.90 per gallon on Labor Day 2026, with analysts noting the impact on trucking, construction, agriculture and rail costs and on consumer prices for goods.
- Economists referenced in the article expect Friday’s August 2026 Consumer Price Index release to show 3.3% year-over-year inflation, and Thursday’s Producer Price Index to quicken to 5.4% from 4.7% in July.
- Treasury Secretary Scott Bessent told Fox News on Sunday, September 6, 2026, that he believes energy prices will fall after the Iran war, saying oil could drop to $40–$50 per barrel given anticipated supply growth.
- Goldman analysts said options markets now imply a 25% probability that Brent will remain above $100 in March 2027, up from 6% a month earlier, which they interpret as markets increasingly bracing for a prolonged conflict.

- Energy analyst Tom Seng of Texas Christian University is quoted saying 'Everything points to the Iran war and the Strait of Hormuz' as the primary drivers of current gasoline prices.
- The article adds that U.S. refineries are currently operating at about 98% capacity, many in extreme Texas heat, and warns that any unplanned outage or hurricane-related disruption could prevent prices from falling seasonally.
- Economist Matthew Metzgar notes that Ukrainian drone attacks on Russian refineries and declining output from Chinese refiners are further tightening global supplies of gasoline and diesel.
- The piece reiterates that national average gasoline prices remain below the all-time record of $5.02 per gallon reached in June 2022, even as the Labor Day-specific record has been surpassed.
