The Houthi Protection Racket: Monetising the Red Sea

Global commerce is about to become subject to a heavily armed tollbooth. Rather than merely launching missiles at passing cargo, Yemen’s Houthi rebels, who seized power in 2014, have hit upon a far more lucrative strategy: sending the shipping industry an invoice. According to the internationally recognised Yemeni government, the militant group is actively developing a payment system to charge commercial vessels for the privilege of transiting the Bab el-Mandeb strait.

This transition from ideological piracy to maritime extortion is not a homegrown Houthi initiative. Intelligence cited by Yemen’s Information Minister, Moammar al-Eryani, suggests the administrative framework for this toll scheme is being designed with the direct assistance of experts from Iran’s Islamic Revolutionary Guard Corps. The plan reportedly involves establishing a dedicated corporate entity to collect transit fees from shipping companies. Eryani characterised the initiative as a dangerous escalation aimed at turning a vital maritime corridor into a permanent revenue stream for the militia.

For anyone observing Tehran’s behaviour in the Persian Gulf, the strategy is entirely familiar. Iran has long insisted on its prerogative to extract tolls from vessels navigating the Strait of Hormuz, which previously handled a fifth of global crude and liquefied natural gas. By exporting this playbook to the Red Sea, the so-called Axis of Resistance—Tehran's network of proxy militias spanning from Lebanon to Iraq—is attempting to franchise its control over global energy arteries.

The audacity of the scheme is matched by the vulnerability of the target. The Bab el-Mandeb, translating to the Gate of Tears, has served as a crucial alternative route for crude deliveries precisely because of the disruptions in Hormuz. Now, energy markets face the prospect of a double stranglehold. The Houthis do not even physically occupy the coastline directly bordering the strait, yet their presence less than a hundred kilometres inland is sufficient to project a credible threat.

This administrative escalation follows months of physical disruption. Houthi assaults on vessels linked to Israel had already forced major shipping lines into lengthy detours around southern Africa. More recently, the group declared a maritime blockade against Saudi Arabia, targeting its oil infrastructure and tankers. The kingdom’s ability to export millions of barrels of crude daily is under sustained pressure.

The response has been predictably forceful. Riyadh has launched retaliatory strikes against Houthi positions, while a combined operation by the United States and Saudi Arabia recently targeted a pro-Iranian militia network in Iraq, resulting in at least twenty casualties. Yet, airstrikes alone rarely dismantle a well-entrenched protection racket. If the Houthis and their Iranian sponsors succeed in monetising the Bab el-Mandeb, the cost of global trade will permanently reflect the price of appeasing heavily armed rent-seekers.
