Brent near $94 and up 6% on the week as Washington readies new Iran measures

Brent is near $94 a barrel and up about 6% on the week, which means wholesale rack costs are climbing regardless of what the pump sign says. WTI is near $87 after five straight sessions of gains. The push is coming out of Washington, not the field: Treasury Secretary Scott Bessent said the administration will lay out new measures to isolate Iran's economy on Monday, and President Trump has called the campaign an "economic D-day."

For anyone buying wholesale gallons this week, the message is plain. Replacement cost is running ahead of what you sold yesterday, and until Monday's detail lands there is no clear read on how far the measures reach. Bessent said they will target Tehran and could also hit countries that deal with Iran, China included. If they do, the crude number that sets your rack could stay firm or push higher.

HYPERFUELS isobutanol

HYPERFUELS LLC, based in Houston, launched a nationwide supply program for renewable isobutanol, pitched as an alternative oxygenate for terminals and marketers serving ethanol-free gasoline markets. The company said it will move the product in bulk by barge and railcar.

For jobbers in ethanol-free territory, marine, small-engine, and premium recreational demand, this is a second renewable oxygenate option that skips ethanol's water-attraction and phase-separation headaches. Whether it pencils out depends on delivered cost against the clear-gasoline blend you run now. Worth a call to your supplier if ethanol-free is a real part of your book.

The Iran-China squeeze

China's independent refiners, the teapots, imported about 534,000 bpd of Iranian crude in August, down from roughly 823,000 bpd in July, per Kpler data cited by Reuters. The US blockade reinstated in mid-July is choking new barrels out of the Persian Gulf.

Iranian crude sitting on the water outside the Gulf and Gulf of Oman is about 83 million barrels now, down from over 100 million before the blockade. The teapots are the biggest buyers of that oil, and with the floating pool draining they may have to source elsewhere as soon as next month.

None of that lands in a US terminal directly. It matters because pulling Iranian supply out of China's diet, from about 823,000 bpd in July to 534,000 in August, tightens the global balance that prices the crude behind your rack.

What to watch

Monday's announcement is the one to read closely, specifically whether the measures name Chinese buyers or stay on Tehran. If they reach China, crude could hold near $94 and rack prices with it. If the detail underwhelms, some of this week's 6% gain could come back off. Watch where the teapots turn for barrels next month.
