Attack on Aramco; Threat to Global Oil Market | Saudi Exports at Risk?

An attack on Aramco's headquarters in Saudi Arabia and rising threats against oil tankers have confronted the energy market with a new wave of uncertainty. Oil prices rose initially in response, but Aramco shares and the Saudi stock index fell in Wednesday trading.

Oil and Energy Group - Anahita Mohib Ali; The headquarters of the state-owned company Aramco in the city of Dhahran, Saudi Arabia, was attacked on the evening of Tuesday, October 13, 2026. The Saudi Ministry of Energy reported a limited fire in an office building and announced that there were no casualties. However, informed sources told Reuters that the fire had spread to several floors of the building and parts of it were badly damaged.

Yemen's Houthis claimed responsibility for the attack and threatened to continue attacks on Saudi airports and oil facilities.

This development has raised concerns about the spread of conflicts and the possibility of targeting critical energy infrastructure in the region.

Despite the damage to the central building, informed sources told Reuters that the operational activities of the Aramco complex continued.

Oil rose in response to Aramco's attack

The global oil market showed an upward reaction to the security developments in the region on Wednesday, October 14. According to Reuters, the price of Brent oil rose 0.82 percent to $106.56 per barrel in part of the trading. US West Texas Intermediate crude oil traded at $95.60 with a growth of 1.55% and reached the highest level in the last three weeks.

The increase in prices was not only related to the attack on Aramco. The concern about the threat of ships passing through the Strait of Hormuz, the increase in the cost of sea transportation and the possibility of disruption in Persian Gulf oil exports also played a role in the growth of prices.

Aramco shares fell; The Saudi Stock Exchange under the pressure of tensions

While concerns about supply disruptions helped boost oil prices, the Saudi stock market reacted negatively. According to a Reuters report, Aramco shares fell 1.6% in trading on Wednesday, October 14, and the main index of the Saudi Stock Exchange ended with a 1.7% decrease. The shares of the country's two largest banks, National Bank of Arabia and Al-Rajhi, each decreased by about 2 percent.

The drop in Aramco's shares occurred in a situation where this company is considered one of the most important players in the world's oil industry and its operational complex manages a wide network of oil fields, refineries, pipelines and export terminals. For this reason, any threat to the company's infrastructure can change investors' expectations about operational risk and possible future costs.

In this case, the negative reaction of the stock market is more a reflection of investors' concern about the spread of conflicts and the possibility of damage to energy infrastructure; Especially, after the Houthis attacked the company's headquarters, they raised new threats against Saudi oil facilities.
