RIYADH, September 16 — A key Saudi oil pipeline has been shut down after a series of escalating attacks by the Iran-aligned Houthi movement, cutting a critical artery for Saudi crude exports and domestic refining. The pipeline typically carries hundreds of thousands of barrels per day. Its closure threatens to disrupt global energy markets already jittery over Middle East tensions, and it lands squarely on Crown Prince Mohammed bin Salman, the kingdom’s de facto ruler and architect of Vision 2030.
MBS faces a dual challenge. He must protect Saudi infrastructure from repeated Houthi drone and missile strikes while sustaining the economic diversification program that depends on stable oil revenues.
The kingdom still relies on petroleum for about 60% of its revenue.
A conflict that has run since 2015
The Houthis, who control large parts of Yemen, have launched dozens of cross-border attacks since 2015, when a Saudi-led coalition intervened in Yemen’s civil war. The conflict has killed over 150,000 people, including thousands of civilians, and created one of the world’s worst humanitarian crises. The United States has provided logistical and intelligence support to the coalition but has recently pushed for a ceasefire.
Peace talks between Saudi Arabia and the Houthis, mediated by Oman, have stalled. The Houthis have targeted Saudi Aramco facilities before, most notably in 2019 when drone strikes knocked out half of the kingdom’s oil production, causing a brief spike in global prices.
That attack, which the US and Saudi Arabia blamed on Iran, exposed vulnerabilities in Saudi air defenses. The Houthis have vowed to continue attacks until the Saudi-led coalition ends its blockade of Yemen.
Oil, OPEC+ and the investment question
The shutdown comes as Saudi Arabia tries to balance its role as a leading OPEC+ producer with pressure to keep oil prices stable amid global economic uncertainty. Any sustained disruption could push oil prices higher, adding to inflationary pressures. It also raises questions about the reliability of Saudi oil supplies at a time when the US and its allies are seeking to isolate Russia over its invasion of Ukraine.
The exact duration of the shutdown is unclear, but analysts warn that prolonged closure could force Saudi Arabia to cut production, affecting global supply. The closure is likely to heighten concerns about the security of Saudi energy infrastructure and could complicate efforts to attract foreign investment.
The kingdom has spent billions on military hardware, including US-made Patriot missile systems, but has struggled to fully neutralize the Houthi threat. MBS, who became crown prince in 2017 and prime minister in 2022, has staked his legacy on Vision 2030, a plan to reduce Saudi dependence on oil by developing sectors like tourism, technology, and entertainment. But the war in Yemen and the Houthi threat have drained resources and diverted attention.
He has sought to reposition Saudi Arabia as a global player, hosting diplomatic talks and investing in sports and entertainment. The ongoing conflict with the Houthis remains a stark reminder of the kingdom’s security challenges.
The United Nations has repeatedly called for a ceasefire, warning that the humanitarian crisis in Yemen could worsen. The US and Saudi Arabia accuse Iran of supplying the Houthis with advanced weapons, a charge Iran denies. The pipeline shutdown is the latest flashpoint in a conflict that has become a proxy war between Saudi Arabia and Iran.
MBS has said he wants to end the war, but a durable ceasefire has proven elusive. The kingdom’s oil infrastructure remains a prime target, and the Houthis have demonstrated their ability to strike deep inside Saudi territory. What to watch next: whether the pipeline restarts, whether the Oman-mediated talks produce anything, and whether Washington’s push for a ceasefire gains traction.
The closure will test Saudi Arabia’s resilience and its ability to protect its most vital resource.
