Global oil and gas equities advanced on Monday as benchmark crude prices climbed above the $100-a-barrel mark, following a U.S. decision to restrict maritime traffic to and from Iran through the Strait of Hormuz after diplomatic talks between Washington and Tehran collapsed.
By 08:35 GMT, Brent crude futures were trading at $102.16 a barrel, up 7.3% on the session, while U.S. West Texas Intermediate climbed roughly 8% to $104.24 a barrel. Both benchmarks had ended the prior Friday on a lower note.
The rebound in oil was mirrored in energy-linked equities on both sides of the Atlantic. In premarket sessions in the United States, ExxonMobil and Chevron each rose more than 2%, ConocoPhillips gained 3.4% and Occidental Petroleum added 3.1%. In London trade, BP and Shell increased by about 1.4% each, TotalEnergies edged up 1.3% and Repsol rose 2%.
The price move followed an announcement that the U.S. Navy would begin blockading the Strait of Hormuz, a measure that was put in place after extended negotiations with Iran failed to produce a settlement intended to end the conflict. Officials said the blockade elevated the geopolitical stakes and undermined a fragile two-week ceasefire that had briefly eased shipping conditions.
U.S. Central Command stated that the blockade would take effect at 10 a.m. ET on Monday and would apply to all maritime traffic entering or leaving Iranian ports on the Arabian Gulf and Gulf of Oman. CENTCOM added that vessels merely transiting the Strait to or from non-Iranian ports would not be impeded.
The move came only days after a ceasefire agreement had appeared to stabilize the situation and temporarily allow shipping through the Strait, an earlier development that had pushed oil prices sharply lower before Monday’s reversal.
Market strategists pointed to physical disruptions and production losses as reasons why futures could diverge from recent lower prices. Rabobank energy strategist Joe DeLaura had cautioned last week, as prices fell after the ceasefire announcement, that oil futures were "far too optimistic," saying there was "so much risk to the upside" not being priced in.
"There’s permanent production loss from the shut ins in Saudi, Kuwait, UAE and Iraq. Refinery and pipeline damage plus the physical restart times, on top of the backlog of 800+ tankers trapped on the west side of the Strait," he said.
"Brent futures seem to have a floor around $90, and I think no ceasefire (no easy opening of a mined strait of Hormuz) means that futures will eventually have to start matching physical markets around $120-130/bbl (or more!)."
Energy stocks, particularly integrated majors and U.S. exploration and production companies, saw immediate upside as traders priced in the elevated geopolitical risk. The moves in oil and stock markets reflected both the direct supply concerns tied to the Strait of Hormuz and investor reaction to the abrupt policy change regarding maritime traffic.
Market context and short-term outlook
With the Strait of Hormuz serving as a critical transit point for crude shipments from the Arabian Gulf, announcements that affect shipping access tend to be rapidly incorporated into futures and equity prices. The combination of reported production disruptions and the backlog of vessels in the area were cited by analysts as factors that could exert sustained upward pressure on physical oil prices if the situation does not normalize.
For the time being, traders and market participants are recalibrating positions across both the oil futures curve and energy-related equities in response to the renewed risk premium embedded in the supply outlook.
