Sydney, March 2, 2026, 17:00 AEDT — After-hours
- Santos shares climbed, tracking a sharp jump in crude prices driven by concerns over Middle East supply.
- Traders’ attention has turned squarely to oil’s trajectory, watching for signs of disruption across critical shipping routes.
Santos Ltd (ASX:STO) finished Monday session 6.7% higher at A$7.21, outpacing the wider market after crude prices surged on the back of weekend strikes targeting Iran, reigniting supply concerns. Woodside Energy rallied 6.8%. Roughly 33.7 million Santos shares traded hands. 1
The decision’s impact comes down to one thing: the price tag on whether oil supply stays uninterrupted. Iran announced it shut down shipping in the Strait of Hormuz—the narrow passage accounting for about 20% of the world’s oil movement. Traders wasted no time. They slapped a fresh “risk premium” onto crude, padding prices to hedge against supply shocks. 2
Santos sees that premium show up in its valuation models before management even opens their mouths. Sharp swings in oil prices cause instant repricing for Australian producers, often shoving the company’s timetable out of the spotlight.
Santos shares moved in a range from A$7.055 up to A$7.370 on the day, with the latest quote coming in at A$7.210. That’s up from its prior close at A$6.760, according to Investing.com data. 3
Ajay Parmar at ICIS points to the Strait of Hormuz: “The key factor here is closure of the Strait of Hormuz,” he said. If the shutdown drags on, oil prices could spike quickly, Parmar warned. 4
Views among strategists diverged on the staying power of the oil rally. Goldman Sachs, with Daan Struyven at the helm, pointed out that prices might “spike above $100” should a prolonged disruption hit Hormuz flows. Societe Generale, on the other hand, argued the surge could fizzle quickly—assuming the conflict leaves supply mostly intact. 5
Energy names moved fast in Australia—Brent crude climbed roughly 6.3% by 4:15pm AEDT, ABC News reported. Oil and gas producers were broadly higher, led by Brazil-focused Karoon Energy at the top of the pack. “It remains to be seen how long this conflict will continue,” Betashares chief economist David Bassanese told ABC. 6
Santos shareholders face a few key dates coming up. According to MarketIndex, the stock traded ex-dividend on Feb. 23, so anyone buying from that date forward won’t get the payout. The final dividend—A$0.1457 a share—lands on March 25. The company’s calendar also flags a quarterly report for April 16. 7
The flip side’s pretty clear: Strait remains navigable, tensions ease, risk premium fades fast. Oil prices drop, dragging energy names—especially those riding momentum—down as well.
The question now: will crude keep these gains, with Europe and the U.S. swinging back open, and are Gulf shipping reports hinting at any relief? Santos holders are watching for two dates—March 25 for the dividend, then the quarterly numbers mid-April.
