The Houthi movement announced a maritime blockade against Saudi Arabia on July 20, 2026, immediately forcing oil tankers to turn back in the Red Sea. The move threatens to push crude prices above $100 per barrel, a level not seen in years.
What the blockade means for shipping
The Red Sea is a critical chokepoint for global oil shipments. Tankers carrying crude from the Middle East to Europe and North America pass through the Bab el-Mandeb strait at its southern end. With the Houthis declaring a blockade, vessels now face the risk of attack or detention. Several tankers have already reversed course, according to shipping data. The alternative route around the Cape of Good Hope adds weeks to transit times and significantly raises costs.
Why the Houthis acted now
The Houthi group, which controls large parts of Yemen including the capital Sanaa, has been at war with a Saudi-led coalition since 2015. The blockade declaration comes amid renewed hostilities and failed peace talks. The group said the measure is a response to Saudi airstrikes and a tightening of the coalition's own blockade on Yemeni ports. The Houthis have previously used drones and missiles to target Saudi oil infrastructure, but this is the first time they have announced a formal maritime blockade.
Impact on oil markets
Oil prices have already risen sharply in recent days. Analysts warn that a sustained blockade could push Brent crude above $100 a barrel, adding to global inflationary pressures. The International Energy Agency has said it is monitoring the situation. Saudi Arabia has not yet announced a formal response, but its navy is expected to try to keep the sea lanes open. The U.S. Navy's Fifth Fleet, based in Bahrain, has also increased patrols in the region.
What happens next
The blockade took effect immediately, but its enforcement remains unclear. The Houthis lack a large navy, but they have anti-ship missiles and sea mines. Shipping companies are now weighing whether to continue transits under naval escort or to reroute. The United Nations Security Council is scheduled to hold an emergency meeting on July 22. No resolution has been proposed yet.
