On the night of 7 April 2026, Iran announced its acceptance of a two-week ceasefire, with negotiations scheduled to commence on 10 April in Islamabad, Pakistan. The decision followed a statement by U.S. President Donald Trump indicating that U.S. strikes would be suspended, contingent upon Tehran’s agreement to fully reopen the Strait of Hormuz.
After two months of coordinated U.S.–Israeli military operations, a central strategic lesson has emerged: modern warfare is increasingly defined by the ability to disrupt connectivity rather than solely destroy military assets. Iran’s asymmetric response demonstrates that critical infrastructureand the vulnerabilities embedded in global interdependence have become a primary instrument of coercion.
U.S. bases in the Gulf, alongside energy facilities, ports, and logistical hubs, are no longer peripheral targets but integral components of escalation dynamics. The temporary disruption of the Strait of Hormuz by Iran’s Islamic Revolutionary Guard Corps demonstrated the structural vulnerability of global energy flows. Approximately 20 to 21 million barrels of oil transit through the strait daily, accounting for nearly 20 per cent of global consumption, while nearly one-third of global LNG trade passes through the same corridor. In this context, infrastructure disruption operates as a force multiplier: even limited attacks can trigger disproportionate systemic effects, translating tactical actions into strategic leverage through market volatility, supply uncertainty, and cascading economic consequences.
Even limited disruptions in this chokepoint have historically generated significant price volatility, with oil markets reacting sharply to perceived supply risks. With the durability of the current ceasefire in doubt, analysts are already identifying key connectivity chokepoints, particularly the Bab al-Mandeb, as likely flashpoints should the truce unravel.
Connectivity as a Strategic Vulnerability
The temporarily paused war illustrates a deeper structural shift in the nature of conflict: connectivity itself has become a strategic domain. Rather than focusing exclusively on military targets, actors increasingly seek to disrupt the infrastructure that sustains economic interdependence, thereby externalising the costs of conflict onto the global system.
The Red Sea corridor carries approximately 12 to 15 per cent of global trade volume and facilitates the transit of around 6 to 7 million barrels of oil and petroleum products per day. Disruptions in this corridor, therefore, have immediate systemic implications, extending well beyond the regional context.
This reflects a transformation in deterrence practices, where the capacity to disrupt connectivity functions as a form of indirect coercion. Control over chokepoints allows actors to impose diffuse but far-reaching costs, effectively linking localised conflict dynamics to global economic stability. In this model, deterrence is no longer anchored solely in military retaliation, but in the threat of systemic disruption.
The Role of the Houthis
The Houthi movement has emerged as a central actor in this context. Since October 2023, the group has demonstrated its capacity to disrupt maritime traffic through missile and drone attacks, particularly in the Bab al-Mandeb corridor. These actions prompted major shipping companies such as Maersk and Evergreen Marine to suspend or reroute operations, often diverting vessels around the Cape of Good Hope. This rerouting extended transit times between Asia and Europe by approximately 10 to 15 days and contributed to a surge in freight costs that, at its peak, exceeded 100 per cent, with direct implications for global inflation.
Despite these capabilities, the Houthis have thus far demonstrated a degree of restraint. Their adherence to the May 2025 ceasefire with the United States, combined with internal political considerations, has limited their engagement to calibrated actions. Their recent missile strikes against Israel indicate entry into the conflict, but not a full-scale escalation aimed at systemic disruption of maritime trade.
In this sense, the Houthis exemplify a broader model of networked warfare: relatively low-cost actors capable of generating high-impact systemic disruption by targeting critical nodes within global trade and energy networks.
Conditions for Escalation
The emergence of the Red Sea as an active front is contingent on three interrelated dynamics:
First, escalation dynamics at the interstate level. Renewed hostilities, including possible strikes on Iran’s energy infrastructure, alongside a potential ground operation, could significantly alter the strategic environment. Such developments would likely increase pressure on Iran-backed actors to expand the scope of the conflict.
Second, the question of operational capacity. While sustained bombardments since 2023 have degraded parts of the Houthis’ military infrastructure, their remaining capabilities are difficult to quantify. Estimates suggest that the group retains a substantial arsenal of missiles and unmanned aerial systems, much of which is stored in hardened underground facilities. However, a sustained campaign targeting maritime traffic would require considerable resource expenditure, potentially incentivising selective and high-impact operations rather than continuous disruption.
Third, the dynamics of proxy relationships. The relationship between Iran and the Houthis is structurally interdependent. Should Iran face an existential threat, its regional proxies would be expected to escalate in support. From this perspective, Houthi involvement in the Red Sea would not be solely a matter of strategic choice but also of systemic alignment within Iran’s regional network.
Implications for Regional and Global Connectivity
Any future escalation in the Red Sea would have significant consequences for both regional infrastructure and global markets. A scenario in which disruptions occur simultaneously in the Strait of Hormuz and the Bab al-Mandeb Strait would effectively constrain maritime access on both sides of the Arabian Peninsula, creating a dual chokepoint crisis.
Even alternative energy routes would face heightened risk. Saudi Arabia’s East–West pipeline, designed to bypass Hormuz, terminates at Red Sea export facilities such as Yanbu. While the pipeline itself is relatively secure, the associated port infrastructure remains vulnerable to targeted attacks, which could undermine its strategic utility.
Importantly, a full blockade is not required to generate systemic effects. Even limited disruptions can trigger cascading responses—suspension of shipping operations, surging insurance premiums, and price volatility—which collectively translate into broader inflationary pressures and economic instability.
Conclusion
The Red Sea is increasingly emerging as a potential extension of the conflict should hostilities renew. The scale and nature of Houthi engagement will hinge on the trajectory of escalation, their operational capabilities, and the evolving contours of Iran’s regional strategy.
More broadly, the conflict underscores a structural transformation in contemporary warfare: the weaponisation of connectivity. As global systems become more interconnected, their vulnerabilities become strategic assets for state and non-state actors alike. Future conflicts are therefore likely to be shaped less by territorial control and more by the ability to disrupt the flows—of energy, trade, and information—that sustain the global economy.
