On Thursday, July 23, 2026, a military spokesperson for Yemen's Houthi movement announced that Houthi forces had attacked two Saudi oil tankers in the Red Sea using missiles and drones. The spokesperson, Brigadier General Yahya Saree, said in a televised address that the ships had broken a shipping ban the Houthis had imposed on the Red Sea (Middle East Monitor; Al Jazeera).

The Houthis are an armed group in Yemen backed by Iran. Before the July attacks, they had declared a blockade — a ban on ships traveling to or from Saudi Arabia through waters the Houthis claim to control. The tanker strikes were described as enforcement of that ban (Ahram Online).

Independent confirmation of the attack came from the United Kingdom Maritime Trade Operations (UKMTO), a British naval organization that monitors shipping safety. UKMTO reported on Wednesday, July 22, 2026, that an "unknown projectile" had struck a Saudi oil tanker (CNBC). The Washington Post also confirmed on July 23 that at least one Saudi oil tanker was attacked in the Red Sea (Washington Post).

The market reacted immediately. Oil prices jumped to $100 a barrel after the attacks on or around July 23, 2026 (Washington Post). The Red Sea is one of the most important shipping routes in the world for oil and other goods. At its southern tip sits the Bab el-Mandeb Strait, a narrow passage between Yemen and East Africa. Think of it as a highway with only a few lanes — if ships cannot pass safely, fewer tankers are available, insurance costs rise, and those extra costs show up in the price of oil people pay at the pump.

President Donald Trump stated on or around July 23, 2026, that the United States would hold Iran responsible for the Houthi attacks on oil tankers in the Red Sea (CNBC). The US military then launched new strikes on Iran amid escalating clashes, following the Houthi attacks on Saudi oil tankers (AP News). The strikes were a direct US military attack on Iranian territory. That step broadens the conflict from a regional dispute between the Houthis and Saudi-linked ships to a direct military exchange between the United States and Iran.

On or around July 28, 2026, the Houthis claimed they fired ballistic missiles at a Saudi oil tanker in the Red Sea. This indicated that the campaign against Saudi ships was ongoing rather than a one-time event (Times of Israel).

The events of the final week of July 2026 follow a clear pattern of escalation. The Houthi blockade declaration created a stated basis, however disputed under international law, for military action. The initial missile-and-drone strikes on two tankers served as the enforcement step. The US decision to hold Iran responsible and launch strikes on Iranian territory elevated the conflict from a regional maritime security issue to a direct military confrontation between two nations. The continued targeting of Saudi tankers with ballistic missiles six days after the initial attacks indicates that neither the US strikes on Iran nor the market disruption have slowed the Houthis down.

The broader context here is the intersection of three pressures that had been building at the same time: the Houthis claiming control over a key shipping route, the US stance of blaming Iran for actions taken by its allies, and the oil market's sensitivity to any disruption in supply routes. The $100-per-barrel price matters because it is the level at which oil becomes expensive enough that consumers and businesses start cutting back. Historically, that kind of pressure pushes governments of oil-importing countries to seek de-escalation. Whether that happens depends on three things: whether the Houthis keep attacking ships, whether Iran responds militarily to the US strikes, and whether the Bab el-Mandeb Strait stays safe enough for commercial shipping. All three of those factors are now changing at the same time.
