What happened
Brent crude (BZ=F) slipped 0.75% to $99.57 a barrel on Tuesday as Strait of Hormuz flows topped pre-war levels, though tanker attacks and tight diesel kept oil near $100. Data firm Kpler said oil leaving the Strait of Hormuz, the narrow sea lane near Iran, ran at 19.5 million to 22.5 million barrels a day on September 27–29, about double a month earlier. Refined fuels such as diesel are lagging, making up only about 11% of shipments versus more than 20% before the war. At least seven tanker incidents were reported in the past week.
Why it matters
Brent crude, the global oil price benchmark, matters because it feeds into what people pay for fuel, shipping and food. More crude leaving the Gulf has eased shortage fears and helped pull Brent back from above $103 to near $100. But diesel, which trucks and farm equipment run on, is still scarce, with US prices hitting a record near $6.50 a gallon late last month. Continued tanker attacks could cut flows again.
