Oil Prices Hit $100 as Houthi Attacks and Iran War Disrupt Supply

Global oil prices have surged past $100 a barrel for the first time since May, driven by Houthi attacks on Saudi tankers and escalating tensions in the Red Sea.

Oil Prices Hit $100 as Houthi Attacks and Iran War Disrupt Supply

The global energy market is experiencing significant turbulence as oil prices surged past the $100 a barrel mark on Thursday. This dramatic increase, the first since May, is attributed to Houthi militants in Yemen claiming responsibility for striking two Saudi tankers in the Red Sea. The escalating conflict between the United States and Iran further complicates the situation, threatening to exacerbate an already severe oil shock.

The Brent crude futures a benchmark for worldwide trading, reached $100.60 on Thursday afternoon, marking a roughly 29% increase over the past month. This surge has catapulted crude prices to their highest level since May 26, 2026. The ripple effects of this price hike were immediately felt across major stock indexes, with the Dow Jones Industrial Average falling by 525 points or 1% while the S&P 500 declined by 1.2%. The tech-heavy Nasdaq also dropped by 2.2%.

The Impact on Global Energy Markets

The recent surge in oil prices represents a significant shift in the energy landscape, as crude costs account for a substantial portion of the price of auto gasoline. The average price of a gallon of gas currently stands at $4.09 according to AAA after having topped $4 earlier this week. This price increase is a stark contrast to the brief dip in oil prices last month, which fell to their lowest level since before the late February outbreak of the Iran war. The hope for a resolution to the conflict was short-lived, as a resumption of large-scale fighting between the U.S. and Iran has imperiled any potential deal.

The escalating tensions have led to a sharp decline in shipping traffic in the Strait of Hormuz a critical maritime trading route that facilitates the transport of about one-fifth of the global oil supply. The U.S. resumed its naval blockade of the Strait last week, reversing a key commitment made as part of the agreement between the U.S. and Iran. This move came after Iran fired upon oil tankers in the strait, further complicating the already volatile situation.

The Houthi Blockade and Its Consequences

The Houthis, who control northern and western Yemen, including the coast at the mouth of the Red Sea, announced a naval blockade on Saudi Arabia on Monday. This blockade has already begun to impact commercial shipping, with two tankers that had just loaded Saudi crude bound for China and India at the Red Sea port of Yanbu making U-turns on Tuesday. These tankers headed towards the Suez Canal rather than out through the Bab el-Mandeb into the Indian Ocean.

British maritime risk management group Vanguard assessed the situation, stating that “The developments represent the first confirmed changes to commercial tanker routing following the (Houthi) embargo and are likely to increase disruption to Saudi crude exports and regional shipping patterns.” With the war shutting down the Strait of Hormuz, the Red Sea has served as the main alternate route for millions of barrels of Saudi oil per day, diverted by pipeline through Yanbu.

The U.S. military has been actively engaged in the conflict, completing the 11th night of strikes on Iran early on Wednesday. These strikes targeted aircraft hangars and drone storage sites, among other strategic locations. The conflict has also resulted in significant casualties, with the number of wounded U.S. personnel growing to well over 500 troops. The U.S. secretary of state, Marco Rubio, emphasized the broader implications of the conflict, stating that Iranian control of the Strait of Hormuz would set a dangerous precedent with repercussions beyond the Middle East.

The Broader Implications of the Conflict

The ongoing conflict has far-reaching consequences for global trade and energy security. The Houthi blockade of the Bab el-Mandeb strait, combined with the closure of the Strait of Hormuz, has the potential to disrupt two of the world’s most important maritime routes simultaneously. This dual disruption could lead to significant delays and increased costs for international shippers, who may need to reroute through the Cape of Good Hope off South Africa, adding one or two weeks to voyages.

Despite the challenges, Saudi Arabia has been able to export some 4 million barrels of oil a day through its Red Sea port of Yanbu. The kingdom could still get crude to market without using Bab el-Mandeb by shipping up to 2.5 million barrels a day across the Red Sea to Egypt, whose SUMED pipeline can carry it to the Mediterranean. Additionally, up to 1 million barrels a day could be shipped through the Suez Canal. However, these alternative routes come with their own set of challenges and increased costs.

The conflict has also highlighted the strategic importance of the Red Sea and the Bab el-Mandeb strait, which are critical for the transport of oil and other goods. The Houthi blockade and the escalating tensions between the U.S. and Iran have underscored the need for a stable and secure energy supply chain. As the situation continues to evolve, the global energy market remains on edge, with oil prices likely to remain volatile in the coming weeks and months.
