Brent crude sat at $100.28 a barrel early Tuesday, off 4 cents by 0003 GMT, then $100.59 in a later update. WTI printed $89.33, then $89.73. Friday closed at $102.25, about 1.9% higher. Prices barely moved; the story behind them is getting louder.

UKMTO warnings count three tankers hit by unidentified projectiles in or near the Strait of Hormuz in early October. A crude tanker was struck on its port side four nautical miles east of Oman on Saturday. Friday brought two more incidents: one vessel suffered minor fire damage and lost power, while another crude carrier was struck nearby. On Thursday, Iran's Fars agency reported a supertanker loaded with 2.5 million barrels catching fire off Oman.

Tehran counts higher: state media carries the Persian Gulf Strait Authority's tally of seven tankers targeted over five days, naming three repeat offenders — AL RUWAIS, SINBAD, MERSIN PROSPERITY — as UAE-owned or chartered. Guard spokesman Hossein Mohebbi warned last Tuesday that vessels entering the waterway without Iranian approval could be struck or hit mines. Washington answered back: Defense Secretary Pete Hegseth insisted the US, not Iran, controls the waterway, calling the American blockade ironclad, with traffic running near pre-war levels every night.

Why it matters

The price says $100 is the new floor. The shipping market says getting there costs more every week.

This is the market's strangest standoff in years: physical flows are holding while the risk around them keeps climbing. Phillip Nova's Priyanka Sachdeva notes that regional crude exports beat pre-war levels on multiple days in late September — alternative routes and logistical workarounds are keeping barrels moving. Her caveat is what traders are pricing: she warned that full normalisation was still premature, because insurance, routing and security costs for every Hormuz transit have jumped.

The figures back her up. Gulf oil flows excluding Iran reached 81% of pre-war volume in September on a Saudi export recovery, with Iranian exports at zero under the US blockade. Commonwealth Bank's Vivek Dhar adds that low inventories are making traders reluctant to believe cheaper prices can last, and shipping rates on the Gulf-to-Asia route have hit record highs.

Policy is pushing back unusually hard. Friday brought the G7 agreement: emergency stockpiles will free up diesel and crude totalling 100 million barrels, channelled through the IEA. After a Macron-chaired video call, the group's joint statement said the release starts immediately and runs four months, front-loading a large diesel tranche inside the first 20 days. Diesel is the urgent part — AAA put Friday's US diesel price at $6.50 a gallon, a record against $5.61 a month earlier, and Trump had threatened a US diesel export ban days earlier. Brent dipped under $100 on the announcement, then climbed back toward $102 by the evening.

What to watch

  • More UKMTO warnings or incidents around Hormuz and the Bab el-Mandeb, where Saudi-backed Yemeni forces retook the coast up to Mocha on Monday — any escalation reprices the premium within hours.
  • Houthi claims vs Saudi confirmation: the Houthis said Monday they struck King Khalid airport outside Riyadh, the Aramco refinery at Rabigh and Abha airport. Riyadh hasn't confirmed — confirmation would be the market's next shock.
  • The IEA release pace: but the first-20-days diesel tranche is the part aimed at the record US diesel price.
  • US-Iran talks remain stalled. Any movement there unwinds the premium faster.

  • Brent–WTI spread at the early Tuesday prints: $100.28 − $89.33 = $10.95 — the freight-and-insurance gap priced into the market.
  • The 100-million-barrel G7 release over four months works out to roughly 830,000 barrels a day — meaningful for inventories, but slow next to a real Hormuz disruption.
  • US diesel at $6.50 a gallon is the political timer here.

MarketRadar take

The price is telling the truth: $100 is the floor the market refuses to abandon — not because barrels are missing, but because the cost of moving them keeps rising with every incident. KCM Trade's Tim Waterer: Brent stays pinned around $100, and the floor looks firm without a diplomatic breakthrough.

Two forces are fighting over the next $10. The G7/IEA release plus recovering Saudi exports can hold the lid for weeks. But each new UKMTO warning or Houthi claim re-tightens the same knot. Watch the Brent–WTI spread more than the headline price: if $10.95 starts widening, the freight market is saying the risk is getting worse.
