Key takeaway

Brent retakes $100 as dark activity grows on collapsed transit volumes.

Brent Crude traded above $106 on Friday 24 April morning and closed at $105.73, a new post-extension high. The price sits 57% above the $67.41 pre-war baseline and marks the first trading day back above the $100 threshold since the ceasefire relief of 21 April priced out. Brent last cleared $100 at contract expiry on 18 April , when it settled at $97.91 after a three-day slide; the current level reverses that compression.

Windward, the maritime-intelligence provider, logged 9 Hormuz transits on 22 April (six inbound, three outbound) against a pre-war baseline above 100 per day 1. Gulf-wide vessel presence climbed to 868 vessels (+108), reversing the 20 April easing, as dark-activity events, defined by Windward as AIS switch-offs or spoofing, rose 13% to 132 events. Three named Windward-tracked vessels tied to the 22 April IRGC seizures appear in the 22 April transit data prior to the interdictions, confirming live tracking.

Dark activity rose 13% on 22 April even as transit count collapsed 91% against the pre-war baseline. Fewer vessels would normally suppress deceptive-shipping signals because fewer hulls are available to hide; instead Windward logged the opposite pattern on the same day IRGC seizures and mine-laying threats escalated. Charterers are still attempting the route but now layering identity obfuscation on every passage, which raises the probability of a misidentified vessel drawing CENTCOM engagement under the verbal shoot-kill order.

For UK motorists the wholesale shift translates to roughly 25-30p per litre above pre-war pump prices if the retail sector passes it through by early May. European haulage desks are pricing the new high into May contracts; Mediterranean LNG buyers are seeing the knock-on in spot markets. With no new Iran instrument signed in Washington, the Brent level is responding to kinetic risk in the strait rather than to paper.

Deep Analysis

In plain English

Oil hit $105.73 a barrel on 24 April, the highest point since the ceasefire relief of 21 April priced out of the market. That is 57% above what oil cost the day before this war started. For UK motorists, it translates to roughly 25-30p per litre above pre-war pump prices. A shipping intelligence firm called Windward tracked only 9 vessels transiting the Strait of Hormuz on 22 April, against more than 100 per day before the war. But it also tracked 132 vessels behaving suspiciously, trying to hide their movements. The strait has not emptied; it has filled with risk instead of cargo.

What could happen next?
  • Consequence

    Dark-activity events rising 13% on the same day IRGC seizure and mine-laying threats escalate means deceptive shipping is growing precisely when the legal and kinetic risk of detection in Hormuz is highest, compressing risk into the same narrow corridor.

Erbil authorities said 10 explosive-laden drones were shot down over the city on 1-2 September with no casualties. Iraq's government condemned the attacks without naming Iran as their source, and neither Washington nor Baghdad confirmed the IRGC's claim to have hit US bases there.

Petra carried a statement that air defences intercepted eight missiles violating Jordanian airspace early on 31 August and 10 of 13 fired on 1 September. The statement named no target and did not address the IRGC's claim to have struck Camp Titin and killed US personnel.

CENTCOM's 1 September target list named IRGC air defence, radar, maritime and mine-laying sites in Iran but no tanker, after Axios reported anonymous officials describing a Trump-approved "tanker for tanker" drone policy. A CENTCOM spokesman declined to confirm the policy and referred questions to policymakers.
