Oil’s 12% weekly jump turns two shipping lanes into the market’s fault line

Oil prices advanced on Friday and headed for their strongest weekly gain in three months as renewed US-Iran fighting threatened two of the world’s most important energy corridors.

Brent crude rose 0.8% to about $84.93 a barrel, while West Texas Intermediate gained 1% to $79.76.

Both benchmarks have climbed almost 12% this week, with Brent poised for a third consecutive weekly advance and WTI for a second.

The rally reflects a widening geopolitical premium rather than a confirmed loss of physical supply, leaving prices highly sensitive to military developments and shipping flows.

Hormuz remains the market’s immediate pressure point

The US military carried out another wave of strikes against Iranian targets on Thursday, marking a sixth consecutive night of attacks, according to US Central Command.

Iran has responded with missiles and drones aimed at American facilities and regional allies.

The escalation has slowed tanker traffic through the Strait of Hormuz, where vessels face higher security, insurance and operating costs.

The waterway typically handles about 20 million barrels a day of oil and petroleum products, equivalent to roughly one-fifth of global consumption.

That exposure explains why even limited disruption can produce a large price response.

Traders are paying not only for barrels potentially removed from the market, but also for delays, rerouting costs and the risk that Gulf exporters may struggle to ship normally.

Red Sea threat broadens the supply-risk map

The concern is no longer confined to the Gulf. Iran has reportedly asked Yemen’s Houthi movement to prepare for action against the Red Sea export route if the US targets Iranian power infrastructure.

A renewed campaign around the Bab el-Mandeb Strait would create a second chokepoint for crude and refined products.

About 4.2 million barrels a day passed through the strait in the first half of 2025, while the wider Red Sea route carries a substantial share of global commerce.

KCM Trade strategist Tim Waterer said the possibility of simultaneous disruption in Hormuz and the Red Sea was keeping a durable geopolitical premium in both Brent and WTI.

That risk should also limit the depth of any correction while the conflict remains unresolved.

Rally still needs confirmation from physical markets

The weekly surge has pushed crude close to one-month highs, but prices remain below levels reached during earlier phases of the conflict.

That suggests traders are worried about supply without yet pricing a full closure of either route.

The next test will come from tanker movements, export volumes and any damage to production or loading facilities.

A sustained decline in flows would strengthen the case for Brent to clear $85 and for WTI to challenge the mid-$80s, a level highlighted by IG analysts.

For now, the bias remains upward, but conviction is tied to geopolitics rather than demand.

Any credible diplomatic opening could quickly remove part of the risk premium, while further attacks on shipping or energy infrastructure would leave buyers firmly in control.
