Oil Prices Climb as U.S.-Iran Maritime Strikes Escalate Tensions

Oil prices continued their upward trend on Monday following a series of retaliatory strikes by the United States and Iran on vessels in the Middle East, intensifying market fears of a significant and prolonged disruption to global energy supplies.

As of 2354 GMT, Brent crude futures climbed 0.54% to $96.80 a barrel, while U.S. West Texas Intermediate (WTI) crude rose 0.72% to $92.14 a barrel. The gains build on a volatile previous week where Brent surged 7.8% and WTI jumped nearly 10%.

The escalation was triggered by military actions over the weekend. U.S. Central Command reported that its forces struck three Iranian oil tankers on Saturday, including one located off the coast of Kharg Island, near Iran’s primary oil export hub.

In response, the navy of Iran’s Islamic Revolutionary Guard Corps said it targeted three oil tankers traveling through what it called unauthorized routes in the Strait of Hormuz, according to a Saturday statement. The IRGC also claimed to have targeted three additional U.S. vessels in other areas.

Market Impact and Supply Concerns

The conflict directly threatens the flow of oil through the Strait of Hormuz, a critical chokepoint where a fifth of the world's oil supply has historically transited. Maritime intelligence firm Marisks called the weekend's events a "major escalation in the maritime conflict," adding that commercial tankers are now being "deliberately used as instruments of reciprocal economic pressure."

Data from analytics firm Kpler on Monday showed the immediate impact on tanker traffic. An average of 10 commodity ships transited the Strait of Hormuz per day over the past 10 days, the lowest volume recorded since May.

Analyst Outlook

Analysts at ANZ said in a note that a prolonged standoff punctuated by calibrated military action appears to be the most likely scenario, delaying a full recovery of Middle East supply. "We then expect exports to remain constrained through the rest of 2026, before a gradual reopening late in Q4 2026," the analysts wrote, noting a full return to pre-war throughput is not expected until late Q1 or early Q2 2027.

Adding to market uncertainty, an Iranian official said a "restricted zone" will be announced outside the Strait of Hormuz in the coming days, according to state media. The developments overshadowed a meeting on Sunday where the OPEC+ producer group decided to keep its oil output policy for October unchanged.
