Middle East oil blockade threat: 27% of supply at risk, energy crisis looms
Key Takeaways
- The potential closure of the Red Sea, on top of the Hormuz shutdown, threatens to remove nearly a third of global oil supply from the market, intensifying the energy crisis.
- This could accelerate the transition to renewables but also risk short-term coal resurgence.

Key Facts
- 1Iran has asked the Houthis to prepare to close the Bab el-Mandeb strait if the U.S. strikes Iranian power infrastructure, according to three anonymous sources.
- 2The Houthis have deployed missiles and drones near Bab el-Mandeb, particularly in Yemen's highlands overlooking Hodeidah and the Gulf of Aden, and are awaiting orders.
- 3The Strait of Hormuz, through which about 20% of global oil passes, is already closed; simultaneous disruption of the Red Sea would cut off the Middle East's two main oil export routes.
- 4IRGC representatives stationed in Yemen will control the decision on when to close the strait, signaling direct Iranian operational command.
- 5The threat follows U.S. President Trump's July 14, 2026, statement threatening to attack Iranian power infrastructure.
- 6As a sign of regional escalation, the Houthis also fired missiles at Saudi Arabia, demonstrating their ability to broaden the conflict.

Analysis
The specter of a dual-chokepoint closure in the Middle East is a brutal reminder of the world's fossil fuel dependency. With Iran's Houthi proxies poised to cut off the Bab el-Mandeb strait, the loss of 27% of seaborne oil trade would not only send prices soaring but also test the resilience of energy systems and climate commitments, potentially triggering a scramble for the dirtiest alternatives.
In a dramatic escalation of the Middle East conflict, Iran has reportedly instructed the Yemen-based Houthi movement to stand ready to close the Bab el-Mandeb strait—the southern gateway to the Red Sea—if the United States strikes Iranian power infrastructure. The directive, conveyed through three anonymous sources and corroborated by a regional insider, adds a perilous new dimension to an already volatile crisis, as the Strait of Hormuz, the other primary Persian Gulf oil export route, remains shut due to Iran's earlier actions. This dual-chokepoint threat could effectively blockade all seaborne oil shipments from the Middle East, removing over a quarter of global oil trade from the market and plunging the world economy into chaos.
Now, with the Strait of Hormuz already closed—a move by Iran that alone affects about 20% of global oil transit—the added closure of Bab el-Mandeb would leave no alternative outlet for Middle Eastern crude.
The Bab el-Mandeb strait, a narrow, 20-mile-wide passage between Yemen and the Horn of Africa, is a critical artery for global energy. Approximately 7% of the world's seaborne crude and a significant share of liquefied natural gas (LNG) flow through it, connecting the Persian Gulf and Indian Ocean to the Suez Canal and Mediterranean. Since November 2023, the Houthis, an Iran-backed rebel group controlling much of Yemen, have demonstrated their ability to disrupt this route by attacking over 100 commercial vessels with drones and anti-ship missiles, forcing major shipping companies to reroute around Africa and sending insurance costs soaring. Now, with the Strait of Hormuz already closed—a move by Iran that alone affects about 20% of global oil transit—the added closure of Bab el-Mandeb would leave no alternative outlet for Middle Eastern crude. Tankers departing from Saudi Arabia, Iraq, Kuwait, and the UAE would be trapped, creating an immediate and severe supply shock.
According to the sources, the Houthis have completed preparations for an attack on shipping, positioning missiles and drones in the highlands overlooking Hodeidah and the Gulf of Aden, and are awaiting orders. Crucially, representatives of Iran's Islamic Revolutionary Guard Corps (IRGC) stationed in Yemen will control the final decision on when to execute the closure, signaling direct Iranian command and eliminating any plausible deniability. This operational framework mirrors the model used in the Straits of Hormuz, where Iran exerted direct control over naval mining and missile placements. The Houthis' missile attack on Saudi Arabia this week further underscores the breadth of their offensive capabilities and willingness to expand the conflict beyond maritime targets.
The impetus for this threat stems from U.S. President Donald Trump's July 14 statement, in which he threatened to attack Iranian power infrastructure—likely a reference to nuclear or electrical facilities—as part of the ongoing confrontation over Iran's nuclear program and regional aggression. Iran's immediate response, channeling its proxy, is a classic asymmetric strategy: it seeks to deter a U.S. strike by holding the global economy hostage. The geopolitical calculus is stark: Washington faces a choice between backing down or risking a catastrophic energy crisis that could destabilize global markets, fuel inflation, and possibly trigger a wider war. The Biden administration, which had previously struggled to deter Houthi attacks, now with Trump in office, may be forced into a broader military commitment, including escalated naval operations and potential strikes on Houthi positions in Yemen, which could draw in Saudi Arabia and further regional actors.
What to Watch
For the energy industry, the implications are severe. Oil prices, which had already risen following the Hormuz closure, could spike to triple digits if Bab el-Mandeb is shuttered. The LNG market would tighten further, with Qatari exports already disrupted by the Hormuz situation and Red Sea closures affecting Egypt's capacity to export. Shipping companies would face warcap premiums, and the global container trade, still reeling from 2024 disruptions, would suffer anew. Beyond energy, the threat could accelerate the fragmentation of global supply chains, with countries scrambling to secure alternative suppliers from the Americas or Africa, but the lack of spare capacity makes a swift offset unlikely.
Looking ahead, the situation remains razor-edged. While the Houthis have not yet acted, the deployment of weapons and IRGC oversight suggest that the closure could be triggered within hours of a U.S. strike. Markets will likely price in a significant risk premium, with commodities, safe-haven currencies, and defense stocks seeing volatility. The crisis could also catalyze a more urgent push for energy independence and renewable sources, as the world is reminded of the perils of fossil fuel concentration. Yet, in the near term, the immediate focus will be on diplomatic efforts to de-escalate—or preparations for a conflict that could reshape the global order.

How we covered this story
Every story in our climate coverage is assembled from multiple primary sources, cross-referenced for factual consistency, and scored along three independent dimensions: sentiment, operational impact, and source-cluster confidence. Single-source rumors and unverifiable claims do not pass our editorial gate. When a story shows "Verified by N sources" with N≥2, the development is independently corroborated; when N=1, we mark it explicitly so readers can weigh the signal accordingly.
Impact scoring uses a 1-10 scale weighted toward regulatory, financial, and operational consequence rather than coverage volume. A topic that runs in every outlet but moves no real decisions ranks lower than a niche regulatory filing that reshapes how operators in the climate space have to behave. Read our full methodology for the scoring rubric, our glossary for term definitions, and our trends index for the longitudinal view across the beat.
Sources are only linked to a story once they clear our classification pipeline at a minimum 35 percent relevance threshold. According to that methodology, reviewed July 2026, this follows multi-source corroboration standards recommended by journalism research bodies such as the Reuters Institute for the Study of Journalism.
