Houthi Control of Bab al-Mandab Strait Disrupts Red Sea Oil Exports

The disruption of oil shipments through a critical maritime chokepoint threatens global energy stability and economic growth.

• Houthi militants captured strategic positions around the Bab al-Mandab Strait, escalating threats to oil shipments.
• Brent crude prices surged above $109 per barrel due to reduced oil transit and increased shipping costs.
• Asian refiners are scrambling for alternative supplies, leading to elevated prices and potential supply chain disruptions.

• Prior to recent conflicts, approximately 20 million barrels of oil per day transited the Strait of Hormuz, a key route for global oil shipments.
• Saudi Arabia has rerouted oil exports through the East-West Pipeline to Yanbu, but recent Houthi advances have severely impacted alternative routes.
• Shipping firms report a 60-70% decline in transits through Bab al-Mandab, forcing tankers to take longer routes around Africa.

The Bab al-Mandab Strait serves as a crucial maritime passage connecting the Red Sea to the Gulf of Aden, facilitating significant oil shipments from the Middle East to Asia. Recent advances by Iran-backed Houthi militants have intensified control over this strategic chokepoint, particularly following their capture of Perim Island and the port of Mocha in Yemen. This escalation comes on the heels of disruptions in the Strait of Hormuz, where geopolitical tensions have already rerouted Saudi oil exports through the East-West Pipeline to the Yanbu terminal on the Red Sea.

As of September 2026, the situation has deteriorated further, with Houthi threats prompting a drastic reduction in oil transits through Bab al-Mandab. In July, initial warnings of a blockade led to price spikes, and by August, Saudi oil flows through the strait had plummeted to just 400,000 barrels per day. The situation worsened in September, with Houthi advances causing an additional 46% drop in transits, pushing Brent crude prices above $109 per barrel.

The implications of these developments are profound. Asian refiners, particularly in China, India, Japan, and South Korea, are now aggressively bidding for alternative oil supplies, which has further elevated prices. Shipping companies are facing increased freight and insurance costs, as tankers are forced to reroute around Africa, adding up to one month of additional transit time for Asia-bound cargoes. This not only affects oil prices but also has a ripple effect on global supply chains, logistics, and consumer prices.

The ongoing conflict and the Houthi's strategic maneuvers highlight the fragility of global energy markets and the interconnectedness of geopolitical stability and economic health. As oil prices rise, the potential for inflation in energy costs looms large, impacting everything from transportation to consumer goods.

• Asian refiners: Facing higher costs and supply shortages, leading to increased bids for alternative oil sources.
• Shipping companies: Experiencing significant declines in transit volumes and rising operational costs.
• Consumers: Likely to see increased prices for fuel and goods due to higher transportation costs.
• Logistics firms: Facing delays and increased costs, impacting supply chain efficiency.

• Oil price trends: Monitor Brent crude prices for signs of stabilization or further increases, which will impact global markets.
• Houthi military actions: Keep an eye on any further advances or negotiations that could alter the current control of the Bab al-Mandab Strait.
• Shipping routes: Watch for changes in shipping patterns and costs as companies adapt to the new geopolitical landscape.
