Iran Orders Houthis to Prepare to Disrupt Bab el-Mandeb Shipping if US Strikes Power Grid

The tension lies between the US strategy of coercive infrastructure degradation and Iran's doctrine of mutually assured economic disruption. Washington asserts that threatening Iran's domestic power grid will force Tehran to the negotiating table. Conversely, Tehran's calculus relies on leveraging proxy forces to hold global energy markets hostage. This theoretical standoff has now materialized into a specific operational directive. According to recent intelligence disclosures, Iran has ordered Yemen's Houthi movement to prepare to close the Bab el-Mandeb Strait if US strikes on Iranian power plants proceed.[1][5]

The primary claim regarding this directive originates from three distinct sources—two senior Iranian officials and one regional intelligence source—who confirmed the communication to international media. The conditional order dictates that the Houthis will seal the Red Sea chokepoint only if the United States executes its threatened infrastructure strikes. This represents a horizontal escalation, shifting the theater of retaliation from the Persian Gulf to the Red Sea.[1][3]

Evidence of Houthi readiness is reportedly visible on the ground, though the extent of their autonomous capability remains a subject of debate. A source close to the militia indicates that logistical preparations are complete. Drones and anti-ship ballistic missiles have been repositioned across Yemen's highlands, specifically in areas overlooking Hodeidah and the Gulf of Aden. These elevated positions provide the necessary line of sight and range to target commercial vessels navigating the narrow maritime corridor.[3]

However, the operational trigger for this blockade appears to be tightly controlled by Tehran, rather than Sana'a. Representatives of Iran's Islamic Revolutionary Guard Corps (IRGC) stationed in Yemen reportedly hold the final authority on when to initiate the attacks. This command structure suggests that Iran views the Bab el-Mandeb not merely as a Houthi theater of operations, but as a direct extension of its own strategic deterrent.[3]

To understand the severity of this threat, the Bab el-Mandeb must be analyzed as one node in a larger, already severely degraded global energy infrastructure chain. The Strait of Hormuz, historically the primary artery for Persian Gulf oil, has been effectively closed to commercial traffic for over 150 days. This unprecedented closure has already forced a massive rewiring of global maritime trade.[4]

In response to the Hormuz bottleneck, regional energy producers have heavily relied on alternative export routes. Saudi Arabia, in particular, has utilized its East-West Pipeline to reroute approximately 70 to 75 percent of its crude loadings away from the Persian Gulf. These shipments now travel cross-country to the Yanbu Port on the Red Sea, bypassing the Iranian blockade entirely.[2][4]

Closing the Bab el-Mandeb Strait would sever this critical bypass. The strait, which is only 18 miles wide at its narrowest point between Yemen, Djibouti, and Eritrea, currently handles roughly 7 percent of global energy supplies. Shutting it down alongside Hormuz would simultaneously disrupt the Middle East's two main oil export routes, effectively trapping millions of barrels of crude and triggering a severe supply shock.[2]

The catalyst for this specific contingency plan was a July 14 statement by US President Donald Trump. In a televised interview, the President warned that the US would "knock out all their power plants, knock out all their bridges" unless Tehran agreed to negotiations. This explicit threat to domestic civilian and dual-use infrastructure crossed a recognized red line for the Iranian leadership.[2][4]

The US military posture in the region has already shifted to support this coercive diplomacy. The US Central Command (CENTCOM) has been conducting preemptive strikes against Iranian command centers, air defense sites, and coastal surveillance facilities. These operations are ostensibly designed to degrade Tehran's maritime threat capabilities, but they also serve as preparatory steps for broader infrastructure strikes if ordered.[2]

Tehran's response aligns seamlessly with its long-standing asymmetric defense doctrine. On July 15, the IRGC issued a public statement clarifying this posture, warning that it would "close all other export corridors that benefit the US and its allies." The statement explicitly noted that "regional energy exports are either shared by all, or denied to all," underscoring the strategy of total economic denial.

Despite the clarity of the strategic intent, the evidence regarding the exact mechanism of the order remains thin. It is not definitively known whether the communication to the Houthis was a formal written directive or a verbal contingency discussion. Furthermore, sources have not specified exactly when the message was transmitted relative to the US President's remarks, making it difficult to determine if this is a reactive measure or a pre-planned escalation.[4][5]

Another area of transparent uncertainty is the Houthis' independent willingness to absorb the inevitable retaliatory strikes that would follow a closure of the strait. While the IRGC may hold the operational trigger, the Houthis would bear the brunt of the kinetic response from the US and its allies. Whether the Houthi leadership views this proxy sacrifice as acceptable remains an untested variable in the alliance's dynamic.

The economic data modeling the impact of a dual-strait closure presents a grim picture, though exact forecasts vary. Maritime trade analytics firms note that the rerouting of vessels around the Cape of Good Hope has already stretched global shipping capacity to its limits. A secondary shock at Bab el-Mandeb would not only spike Brent crude prices—which have already seen significant volatility—but also severely disrupt the transport of refined products and liquefied natural gas (LNG).[2][4]

The evidence regarding the effectiveness of the Houthi missile deployment is also mixed. While the group has demonstrated the capability to hit commercial vessels, achieving a total blockade of an 18-mile-wide strait requires a sustained barrage capable of overwhelming modern naval defense systems. The US and allied naval coalitions in the Red Sea have maintained a high interception rate against Houthi projectiles, suggesting that a complete closure may be more aspirational than guaranteed.

Ultimately, the current intelligence paints a picture of a region locked in a precarious escalation ladder. The data confirms that the hardware is in place and the strategic directives have been issued. However, the transition from deterrence to active blockade hinges on a sequence of conditional triggers—starting with the US execution of its infrastructure threats—that neither side fully controls.[1][3]
