Oil Prices Rise After Iran Claims Attack on Two Tankers in the Strait of Hormuz

Oil Prices Rise After Iran Claims Attack on Two Tankers in the Strait of Hormuz

Finance-Solutes.com Research Desk · August 1, 2026

Oil prices climbed on July 31 after Iran’s Islamic Revolutionary Guard Corps (IRGC) said it had struck two oil tankers attempting to transit the Strait of Hormuz, the latest flashpoint in a widening conflict that is once again squeezing global energy supply.

West Texas Intermediate (WTI) crude rose more than 1% to settle at $84.67 a barrel, while Brent crude also advanced, trading in the high-$80s per barrel range. Even with Friday’s gain, oil ended the week lower after an early-week sell-off tied to hopes that Middle East tensions would ease.

Investor takeaway: The Hormuz strikes and the Chevron and Exxon CEOs’ warnings that supply risk is “no longer limited” to the strait suggest energy markets should stay on alert for further volatility. Traders should treat this as an evolving, headline-driven situation rather than a one-off spike, and watch refined-product shortages — not just crude supply — as the next pressure point on prices.

What Happened in the Strait of Hormuz

The IRGC said its forces struck two oil tankers early Friday as the vessels attempted to pass through the Strait of Hormuz under U.S. military air escort, according to Iran’s state-run PressTV. The IRGC said the tankers had ignored Iranian warnings and were operating on guidance from U.S. Central Command (CENTCOM). Four additional tankers reportedly changed course and turned back following the incident.

U.S. and U.K. maritime security organizations that track shipping activity in the Middle East had not independently confirmed the attacks as of Friday. Tehran has maintained since fighting between the U.S. and Iran resumed this month that the strait remains closed and that safe transit requires coordination with the IRGC Navy, while CENTCOM continues to insist Iran does not control the waterway.

Supply Risk Spreading Beyond Hormuz, Chevron and Exxon Say

Chevron CEO Mike Wirth told CNBC on Friday that the threat to Middle East oil supply has expanded beyond the Strait of Hormuz, adding that global crude inventories continue to decline as the conflict drags on. Exxon CEO Darren Woods has separately pointed to the strait’s outsized role in global energy flows, noting that oil producers have had to scale back some Gulf operations as the ability to move crude out of the region grows more difficult.

Both majors posted sharply higher second-quarter profits on the back of this year’s oil price rally, with Chevron’s net income climbing steeply from a year earlier as elevated prices offset the operational disruption in the region.

• Energy and transport-heavy sectors: Sustained higher crude and refined-product prices raise input costs for airlines, shippers, and consumer-facing businesses.
• Integrated oil majors: Chevron and Exxon are direct beneficiaries of the price rally, though both face rising operational and security costs in the region.
• Inflation-sensitive assets: A prolonged supply squeeze adds fresh upward pressure on headline inflation, a factor markets will weigh against the Federal Reserve’s rate path.

Conflict Widens Across Multiple Maritime Chokepoints

The Hormuz incident is one of several simultaneous flashpoints now affecting global energy shipping. Iran-backed Houthi forces in Yemen declared a maritime blockade against Saudi Arabia last week and have continued targeting tankers in the Red Sea. In Egypt, a drone strike caused fires aboard two vessels at the Damietta LNG terminal on the Mediterranean coast on July 29 — a U.S.-owned floating storage and regasification unit and a Bermuda-flagged LNG carrier — though no group has claimed responsibility and no injuries were reported.

Separately, tankers in the Black Sea have come under attack amid Ukraine’s continued strikes on Russian energy infrastructure, raising concern over crude flows through the Caspian Pipeline Consortium (CPC), a key export route for Kazakh oil to international markets.

Market snapshot (July 31, 2026 close): WTI crude settled at $84.67/barrel, up roughly 1% on the day; Brent crude traded in the high-$80s. Energy prices remain highly sensitive to fast-moving headlines from the region — always check live pricing before acting on any figures in this article.

The Bigger Concern: A Refined-Product Shortage, Not Just Crude Supply

Industry analysts note that the more pressing issue for the global economy may not be raw crude supply but a shortage of refined products such as diesel and jet fuel. Russia has halted diesel exports following Ukrainian strikes on its refining infrastructure, while Middle East refined-product exports have also been disrupted by the instability around Hormuz. Estimates from energy research firms suggest several million barrels per day of global refining capacity are currently offline, a gap that ripples through transportation and agriculture costs well beyond the region directly affected by the conflict.
