Oil price surge Iran pushes Brent to $98.73, a six-week high

Crude oil is creeping back toward the psychological $100-a-barrel mark, and the reason is hard to miss: Iran. The latest oil price surge tied to Iran’s threats against Gulf energy infrastructure accelerated this week after Tehran and Washington traded military blows over the weekend, rattling a market that has been on edge for months over the ongoing conflict.

Key takeaways

• Brent crude jumped 1.5% to $97.73 per barrel and West Texas Intermediate rose 1.8% to $93.10, marking a six-week high.
• Crude prices have climbed more than 30% since late February, when the conflict began.
• Iran threatened to impose a maritime exclusion zone in the Persian Gulf and warned that U.S. energy companies operating there face real risk.
• Saudi Aramco’s Jazan facility, home to a 400,000-barrel-per-day refinery, was struck again, though damage was described as limited.
• Iran is negotiating with Oman on a secure shipping corridor through the Strait of Hormuz, a waterway that carries roughly 8 million barrels of oil a day.

Oil Prices Surge Near $100 Amid Iran’s Gulf Infrastructure Threats

Brent futures and West Texas Intermediate both jumped this week, pushing oil to levels not seen in six weeks, as traders priced in the risk that Iran’s rhetoric turns into real disruption of Gulf supply.

Recent Price Movements

Brent crude advanced 1.5% to reach $97.73 per barrel, while U.S. West Texas Intermediate jumped 1.8% to $93.10. That followed a Monday session in which Brent already climbed roughly 1.5% to $97.73 and briefly touched $97.93 — its highest level since July 23 — while WTI rose 1.8% to $93.10, also a level not seen since late July, according to CNBC. The momentum has been building for weeks. Brent gained 8% last week alone, while WTI advanced nearly 10%, and crude prices overall have now risen more than 30% since the conflict’s outbreak at the end of February.

Impact of Iran’s Threats on Market

This latest oil price surge driven by Iran’s rhetoric comes directly on the heels of a weekend flare-up between Washington and Tehran, which included reciprocal strikes on vessels moving through the Persian Gulf. The rising crude costs have already spilled over into everyday fuel prices — gasoline and diesel both hit record highs heading into the Labor Day weekend, according to CNBC.

Iran’s Escalating Rhetoric and Maritime Exclusion Zone Threat

Iran has moved from warnings to explicit threats against American energy interests in the Gulf, raising the stakes for any company still operating in the region.

Official Warnings to U.S. Energy Companies

Tehran framed its threats as a response to what Iranian officials called U.S. “economic warfare,” announcing plans to establish a maritime exclusion zone spanning the Persian Gulf. Mohammad Baqer Qalibaf, Iran’s Parliament Speaker, warned that American energy corporations operating in the area face significant vulnerability. “The oil and gas production chain here is sprawling, accessible, and exposed,” he said. “Strike our assets, and you get struck. We’ve already proven it.”

Declarations by Iran’s Parliament Speaker and Security Council Secretary

Mohsen Rezaei, secretary of Iran’s Supreme National Security Council, posted on X that Washington had received a “clear warning” and that continued economic pressure would trigger a maritime exclusion zone matching the scope of what Tehran describes as a U.S. blockade. The exchange follows a weekend escalation in which After Iran fired ballistic missiles at two Navy warships on Saturday, the U.S. military targeted three Iranian oil tankers, according to U.S. Central Command, which described the vessels as part of a “multibillion-dollar shadow network” funding Iran’s Revolutionary Guard and its regional proxies. U.S. Defense Secretary Pete Hegseth had earlier warned the U.S. “will destroy (and sink)” Iranian oil tankers if Iran fired on American vessels. Iran’s Foreign Ministry called the strikes on commercial vessels a “war crime” and an act of “economic warfare.” The clash comes as the broader conflict, which resumed after roughly a month of relative calm, passed the six-month mark in August.

The Strait of Hormuz: Global Oil Transport’s Critical Chokepoint

The Strait of Hormuz has become the single most-watched piece of geography in global energy markets right now, because any disruption there threatens a huge share of the world’s seaborne oil trade.

Importance of the Strait

The strait remains the focal point for energy traders given its role as a critical chokepoint for global oil transportation. Iranian officials have signaled intentions to establish a new restricted maritime zone in the Gulf alongside an alternative shipping corridor, a plan that has heightened concerns about potential delays for tankers moving through the waterway.

Iran-Oman Negotiations for Secure Shipping Corridor

Tehran has indicated that talks with Oman over Hormuz shipping protocols are nearing completion, describing the negotiations as entering their final phase. The proposed arrangement would create a temporary secure passage through the strait. Even so, market participants remain skeptical that diplomacy alone will resolve the underlying conflict anytime soon.

Risks in Tanker Movements

U.S. Energy Secretary Chris Wright noted that roughly 8 million barrels per day continue to move out of the Persian Gulf on average, but tanker vessels routinely disable their transponders to avoid detection — a practice that makes it harder to track shipping activity and assess real-time risk in the corridor.

Saudi Aramco Infrastructure Attacks and Operational Impact

Saudi Aramco’s facilities have become recurring targets, adding another layer of supply-side anxiety on top of the standoff over the Strait of Hormuz.

Attacks on Jazan Facilities

Saudi Aramco’s energy installations in Jazan, on the Red Sea coast, were hit again on Monday. According to the Financial Times, damage assessments were still underway at the facility, home to a 400,000-barrel-per-day oil refinery, and it wasn’t immediately clear who was responsible for the strike.

Resulting Disruptions and Market Sensitivities

While the attack caused limited physical damage, it’s the latest in a string of strikes that had already forced a nearby refining facility to suspend operations. Every fresh oil price surge tied to Iran and its Gulf campaign raises the stakes for refiners, shippers, and ultimately drivers already facing record fuel costs. Markets are treating each incident — however contained — as a signal that Gulf supply chains remain exposed to sudden shocks, which helps explain why prices keep reacting sharply even to attacks described as limited in scope.

Traders are now watching two tracks at once: whether the Iran-Oman talks actually produce a workable shipping corridor, and whether further strikes on tankers or Saudi infrastructure push crude decisively past the $100 line that has loomed over this market for weeks.
