As the regional security situation in the Middle East continues to be uncertain, the Houthis recently claimed attacks on Saudi Arabia’s energy infrastructure, reopening a volatile front. Saudi-linked commercial vessels, including the NCC MASA, were also attacked in the Red Sea. Although the vessel sustained only minor hull damage and continued its voyage safely, the attack highlights a serious violation of international law. The Saudi-led coalition responded by striking Houthi military positions in Hodeidah and warned that any further attacks would invite a stronger military response. In the current context, the Houthi attacks point toward a calibrated escalation that is linked to Iran’s attempts to increase the pressure and strengthen its bargaining position vis-à-vis the United States.
The recent tensions in the Red Sea coincide with tentative efforts to revive negotiations between Washington and Tehran after the collapse of the ceasefire agreement. The Houthis are acting in close coordination with Iran, aiming to increase pressure on the global economy and aggravate the economic cost of escalation. Iran’s agenda is largely focused on convincing Washington that continued coercion will trigger regional instability and escalate the scale of disruption.
The repeated attacks in the Red Sea are intended to disrupt critical sea lines of communication (SLOCs). Saudi Arabia has sought to diversify its oil export routes amid growing tensions in the Strait of Hormuz. Riyadh in recent months has increasingly relied on Yanbu port for oil trade. As per data by Kpler, all of Saudi Arabia’s seaborne crude exports departed from Yanbu in April and May, with the port accounting for 92% of exports in June and 78% in July. By targeting the Red Sea, Iran and the Houthis seek to deny Saudi Arabia a secure alternative export corridor and consequently exert pressure by disrupting energy supplies and driving up global oil prices. Such attacks significantly raise the perceived maritime risk, disrupting commercial shipping through higher insurance costs. The escalation coincided with rising tensions in the Strait of Hormuz, where an oil tanker struck a naval mine, and Iran claimed to have intercepted several vessels for allegedly violating designated shipping routes.
By deliberately targeting commercial vessels, the Houthis have violated the United Nations Convention on the Law of the Sea (UNCLOS). Shipping through the Bab al-Mandab Strait declined significantly following the attacks, while disruptions in both the Red Sea and the Strait of Hormuz simultaneously constrained two of the world’s most critical energy corridors. Consequently, this pushed oil prices to their highest levels in months, with oil prices surging to $100 per barrel shortly after the attacks.
These attacks can also be seen as a continuous attempt by the Houthis to challenge Saudi Arabia’s long-term ambitions as well as its regional power and influence. Houthis lack the capacity to directly challenge Saudi Arabia economically or militarily. The Houthis continue to rely on irregular warfare to increase the costs of defending critical infrastructure and securing sea routes. Iran exploits the Houthis’ geographical position along the Bab al-Mandab to impose costs on its adversaries indirectly. With Hamas weakened, Hezbollah constrained and Iran’s influence in Syria largely collapsed, Tehran has increasingly relied on the Houthis to provoke and escalate tensions. Through proxy warfare and coercive diplomacy, Iran and the Houthis seek to raise the costs of pressure on Tehran while preserving their strategic relevance in the regional security order. This has been a common strategy used by non-state actors in asymmetric conflicts, where they do not aim to defeat stronger powers militarily but instead exploit the structural vulnerabilities and threaten to widen the scope of the conflict.
By launching attacks on Saudi territory and targeting commercial shipping, the Houthis have reignited a cycle of military retaliation that threatens to undermine the de-escalation achieved since 2022. Saudi strikes on Houthi military infrastructure have been framed as responses to these attacks, while Riyadh has warned that any further Houthi aggression will invite uncompromising military action. Such escalations increase the likelihood of miscalculation, particularly because the Yemeni theater is now closely intertwined with the wider US-Iran confrontation.
As of now, the Houthi strategy appears to be one of controlled escalation. The strategic value of the Houthis for Iran lies in their ability to threaten one of the world’s most critical maritime arteries. Tehran understands that disrupting SLOCs and threatening Saudi oil exports is among the most effective means of generating international pressure. According to some officials, Iran recently reinforced the Houthis by sending IRGC commanders, military advisers, missiles and drone equipment to Houthi-controlled Yemen. The timing suggests that these reinforcements are intended to strengthen the Houthis’ ability to enforce a naval blockade in the Red Sea. This reveals Iran’s longstanding strategy of enhancing Houthi military capabilities through weapons transfers, training and intelligence support, despite Tehran’s denial of the extent of its support for the Houthis.
Although the Houthis exercise de facto control over significant territory in Yemen, they lack international recognition and legitimacy. The Houthis benefit from Iranian military support to consolidate their control over parts of Yemen and sustain their position. However, it is obvious that Iran not only lacks the intent but also the economic capacity to contribute meaningfully to Yemen’s reconstruction and long-term development. Perhaps the greatest irony is that every time such escalations happen, Yemeni citizens become the principal casualty. The country continues to experience one of the world’s most severe humanitarian and economic crises, with widespread institutional collapse, poverty and food insecurity. As per the UN, nearly half of Yemen’s population is projected to experience acute food insecurity, with famine threatening tens of thousands. Instead of prioritizing domestic reconciliation, the Houthis’ regional strategy increasingly complicates Yemen’s peace process and reverses any progress made. As long as Yemen remains embedded within the wider US-Iran rivalry, the country’s prospects for sustainable peace remain bleak.
The latest attacks should be understood within the wider context of Saudi Arabia’s longstanding political, economic and humanitarian engagement in Yemen. Saudi Arabia remains one of Yemen’s largest donors and humanitarian aid providers, while also supporting the internationally recognized Yemeni government. Its response to recent escalations has largely aligned with broader regional and international interests, focusing on avoiding escalation and preserving avenues for a diplomatic resolution. Saudi Arabia has pursued a calibrated response focusing on protecting commercial shipping and freedom of navigation in the Red Sea. Riyadh has emphasized that civilian infrastructure and ports were deliberately spared, while reiterating its support for a political settlement in Yemen and warning that further Houthi attacks would invite a stronger response. At the same time, Riyadh also has been engaging closely with global powers and regional partners to enhance deterrence and promote a coordinated diplomatic response.
The recurring nature of Houthi attacks highlights that the challenge is embedded within the broader regional security dynamic rather than being limited to individual episodes of escalation. Repeated Houthi threats against strategic chokepoints risk creating a dangerous precedent in an already volatile region, where disruptions to maritime trade and critical infrastructure could lead to severe economic and security consequences. Such attacks undermine international security norms and challenge the rules-based international order. Therefore, failure to deter these threats risks allowing maritime coercion to emerge as a tolerated strategy in asymmetric conflicts.
