Saudi Oil Under Siege: Houthis, Iraqi Militias Tighten Grip on Dual Export Routes
As Houthi rebels seize Red Sea chokepoints and drones attack the East-West pipeline, Saudi Arabia faces simultaneous threats to its last two escape routes from the Iran war.
Yemen's Iran-backed Houthi rebels have captured strategic territory along the Red Sea coast, including the port city of Mocha and islands in the Bab al-Mandeb Strait, extending their reach to one of the world's critical shipping chokepoints. The seizure comes as separate drone attacks from Iraq—blamed on Iranian-backed militias—struck Saudi Arabia's East-West pipeline on September 10, forcing its shutdown the following day. The pipeline, which carries up to 7 million barrels per day, had become Saudi Arabia's primary workaround after the Strait of Hormuz was largely closed by Iranian actions during the ongoing US-Iran war that began in February.
The twin threats have dramatically compressed Saudi Arabia's export options. The kingdom's oil shipments to Asia collapsed from 3.4 million barrels per day in June to just 128,000 in August, though they recovered somewhat to 700,000 this month. The East-West pipeline closure could remove up to 4-5 percent of global oil supply from markets, and repairs are expected to take weeks. Oil prices broke above $100 per barrel for the first time in months, driven by trader concerns over Saudi supply disruption.
The coordination between the Houthis and Iraqi militias reflects a broader strategy by Iran to maximize pressure on Saudi Arabia during a period when a preliminary ceasefire between the US and Iran has collapsed. The Houthis justified their July escalation as retaliation for Saudi airstrikes and as a response to what they call Saudi-imposed blockades on Yemen. Saudi officials have sought backing from the Trump administration; while the US has reaffirmed its defense commitment to the kingdom, Washington has signaled reluctance to take direct military action to counter the Houthi threat.
Shipping traffic through the Bab al-Mandeb has recovered from an initial dip after Houthi advances, but the threat remains. Houthi officials claim their focus is on Saudi-linked shipping, though analysts warn they could expand targets to pressure both the Saudi government and the global economy. The simultaneous closure of both major export routes creates what one regional official described as an "existential" challenge for Saudi oil production—a situation with no precedent since the kingdom's founding.
How could this affect you
Traced by who's actually in the path of this — not everyone is.
Direct
Energy importers (EU, India, Japan, South Korea)
Closure of Saudi East-West pipeline removes 4-5% of global crude supply; Bab al-Mandeb Red Sea route now contested by Houthis who control chokepoint approach. With Strait of Hormuz restricted since Iran war, limited alternative routing remains. Oil broke above $100/barrel this week; sustained supply loss could drive prices to $120+ and trigger rationing or recession in import-dependent economies.
Likely
US energy security and Middle East strategy
Saudi Arabia's oil export capability—critical to Trump administration's goal of lower global energy costs—is now at risk from coordinated Iranian proxy action. Saudi requests for US military assistance signal potential need for expanded American commitment despite Trump's stated preference for negotiation with Iran. If Saudi exports continue falling, pressure for direct US intervention in Red Sea shipping could mount.
Tanker availability and insurance costs will rise as Red Sea route becomes higher-risk. Refineries dependent on Saudi crude may need to substitute Iranian crude (if US blockade lifts) or more expensive alternatives. Transport costs per barrel could rise $5-15 depending on rerouting distance and security premiums.
Possible
Iran's negotiating leverage vs US
Iranian proxies' success in strangling Saudi exports without direct Iranian action demonstrates Tehran can impose costs on US allies without escalating direct Iran-US conflict. This could entrench Iran's refusal to grant full Strait of Hormuz access in any future ceasefire negotiation, as Iran can claim it controls regional oil flow via proxies.
