Houthis Develop Extensive Financial Network Amid US Sanctions

<p>The Houthis have advanced toward the Bab el-Mandeb Strait, a key shipping route, raising concerns about their financial network that has enabled their transformation from a Yemeni insurgency to a regional power. The group has gained control over territory along Yemen’s Red Sea coast, including the port city of Mocha, which is vital for global trade.</p><p>The U.S. government is facing challenges in addressing the financial support for the Houthis while trying to avoid humanitarian impacts on civilians. The Houthis have established a sanctions-evasion network that includes control over ports and trade routes, complicating efforts to cut off their funding.</p><p>Adam Rousselle, founder of Between the Lines Research, stated that the Houthis operate a financial network that extends beyond Yemen. In a 2025 investigation for the Global Network on Extremism and Technology, he identified a financing system involving Houthi-controlled ports, tariffs, Iranian oil, hawala networks, cryptocurrency exchanges, and foreign facilitators from various countries.</p><p>Control of ports is crucial for Houthi revenue, as Yemen relies heavily on imports. Rousselle's report indicates that the Houthis impose fees at ports they control and tariffs on goods from rival ports. Their recent territorial gains could enhance their economic base.</p><p>Nadwa Al-Dawsari, a Yemen expert, testified before the House Foreign Affairs Committee on September 1, stating that territory is essential for the Houthis to maintain power and military capabilities. She noted that their territorial base allows them to recruit, generate revenue, manufacture weapons, and control smuggling routes.</p><p>Rousselle emphasized that the Houthis' finances should not be seen as merely receiving funds from Iran, but rather as part of a broader Iranian commercial ecosystem. Miad Maleki, a senior fellow at the Foundation for Defense of Democracies, added that the Houthis are not immune to sanctions but have adapted to them, generating most of their revenue within Yemen.</p><p>The U.S. Treasury estimates that the Houthis generate over $2 billion annually from oil sales and receive oil shipments from Iran through affiliated companies. The Houthis also collect taxes on petroleum imports.</p><p>Sa’id al-Jamal, identified by the Treasury as a key financial official for the Houthis, operates an international network that sells Iranian commodities and channels proceeds to the group. The Treasury has documented al-Jamal’s network procuring weapons and sensitive goods from Russia and identified digital wallets used by the Houthis, with nearly $900 million in outflows noted.</p><p>Rousselle cautioned against viewing the $900 million figure as a complete representation of Houthi wealth, stating that the network is complex and difficult to quantify. He noted that Russia has become increasingly involved in supporting the Houthis, while Al-Dawsari highlighted the group's expanding ties with other adversaries, including Russia and China.</p><p>Reports indicate that Russia has provided targeting data for Houthi attacks on Western ships, and Chinese companies have been linked to the Houthi supply chain, although direct government involvement remains unproven. Al-Dawsari noted that a Chinese satellite company has provided imagery supporting Houthi operations against U.S. warships.</p><p>The extensive financial network poses challenges for the U.S. Treasury's efforts to isolate Iran economically. Rousselle remarked that decentralized illicit finance networks complicate enforcement, as shutting down one network often leads to the emergence of another. Maleki suggested that the U.S. focus on points where Houthi finances intersect with the formal financial system.</p><p>Oman is identified as a potential pressure point for the Houthis, but efforts to disrupt their finances must consider the humanitarian situation in Yemen, where the Houthis control key infrastructure for civilian supplies. Rousselle expressed uncertainty about how to address Houthi revenue without exacerbating the humanitarian crisis.</p><p>Maleki argued that the U.S. should ensure that humanitarian trade continues without generating revenue for Houthi authorities. Rousselle warned that the challenge of regulating financial systems extends beyond Yemen and involves any sanctioned actor capable of exploiting unregulated financial networks.</p><p>The Treasury Department did not respond to requests for comment.</p>
