Two supertankers struck in the Strait of Hormuz — oil supply under threat

Supertankers attacked in the world's most critical oil artery

Two of the world's largest oil tankers were struck by unknown projectiles on Tuesday while transiting outbound through the Strait of Hormuz from the Persian Gulf. This was reported by maritime risk analysis firm Marisks, as cited by Bloomberg.

One of the vessels is the VLCC tanker "Sidr", operated by Saudi Arabia's state-owned shipping company Bahri. The ship was struck northeast of Khasab in Oman. The second vessel is the "Senegal Prosperity". Both are classified as very large crude carriers — tankers capable of carrying more than two million barrels of crude oil.

A vulnerable chokepoint under pressure

The Strait of Hormuz is one of the world's most strategically critical maritime routes. Around 20 percent of global oil consumption passes through this narrow strait between Iran and Oman, according to energy analysts. Any disruption here has an immediate impact on oil prices and broader energy security.

Tuesday's attacks come during a period marked by persistent tensions in the Middle East. According to OilPrice.com, the fragile recovery in oil supply from the region is now being put at risk.

A grim track record — markets react swiftly

This type of incident is not without precedent. Attacks on Saudi Aramco's facilities at Abqaiq and Khurais in September 2019 sent Brent crude up more than 19 percent in a single day — the largest single-day gain ever recorded in the Brent market. The production loss at the time amounted to approximately 5.7 million barrels per day, close to five percent of total global output.

In 2026, the pattern has repeated itself on several occasions. When the Houthi movement carried out missile strikes against Saudi Aramco facilities in July 2026, Brent briefly surged to 100 dollars per barrel, according to available market data. In the aftermath of similar incidents, risk appetite in financial markets has fallen noticeably, historically resulting in pressure on equities and cryptocurrencies while gold and the dollar have strengthened.

Market implications: oil, inflation, and risk sentiment

Energy analysts emphasize that supply disruptions in the Strait of Hormuz can quickly feed through to global inflation dynamics. Higher oil prices raise energy costs for industry and households, which in turn may pressure central banks to maintain or tighten monetary policy.

It has not yet been confirmed who is behind Tuesday's attacks. Marisks, the source of the information, is a private maritime risk analysis firm, and the details have not yet been verified by government authorities or international maritime organizations. 24markets stresses that individual reports from commercial risk firms should be read with this caveat in mind.

The Oslo Stock Exchange (OSEBX) and Norwegian energy stocks are being closely monitored in the wake of the incident, as Norwegian oil companies — and Norwegian oil price exposure in general — typically react to geopolitical supply shocks from the Gulf. Brent crude is not quoted at the time of writing, but market participants expect upward price pressure if the situation deteriorates.

The situation remains unresolved

It is too early to say how the incident will develop. No state has claimed responsibility as of the time of publication. It is also not yet known whether crew members have been injured, whether the ships have sustained damage below the waterline, or whether any oil cargo has leaked.

Energy markets and international shipping will be monitoring the situation closely over the coming hours. If the attacks are confirmed to be coordinated or state-sponsored, they will likely trigger stronger diplomatic and military responses — and further turbulence in commodity markets.
