The Shifting Battle: From Oil to Shipping Corridors

For much of the twentieth century, oil was regarded as the world's most powerful geopolitical weapon. In the twenty-first century, however, control over global shipping corridors may prove equally—if not more—consequential. Whoever can influence the world's maritime chokepoints can shape not only energy supplies but also international trade, supply chains, and economic stability. Against this backdrop, the Red Sea appears to be emerging as the next major strategic battleground.

Following months of disruption around the Strait of Hormuz, growing concerns are now centered on the security of commercial shipping through the Red Sea. Together, the Strait of Hormuz, the Bab el-Mandeb Strait, and the Suez Canal constitute one of the world's most vital maritime corridors, carrying a substantial share of global trade, including oil, liquefied natural gas, manufactured goods, agricultural commodities, and containerized cargo. Any prolonged disruption would ripple across continents through higher freight costs, supply-chain bottlenecks, inflationary pressures, and increased energy prices.

The immediate question is not simply who is attacking commercial vessels, but who stands to gain from sustained instability in these strategic waterways.

Western governments and much of the international media have attributed recent attacks to Yemen's Houthi movement, arguing that the group continues to target maritime traffic as part of its confrontation with Israel and its Western allies. Given the Houthis' own public statements and previous operations, this explanation cannot be dismissed.

Yet geopolitics is rarely straightforward.

Military confrontations are increasingly accompanied by information warfare, where competing narratives emerge almost as rapidly as military events themselves. Some analysts caution against assigning responsibility before credible, independent investigations establish the facts. Premature conclusions can become powerful geopolitical tools, shaping public opinion and diplomatic responses long before evidence is fully examined.

Another line of analysis raises a different possibility. It suggests that if vessels linked to Saudi Arabia increasingly become targets, the objective may extend beyond disrupting commercial shipping. Such incidents could undermine the fragile rapprochement between Riyadh and Tehran, reviving regional rivalries that had begun to ease after years of confrontation. Those who favour a polarized Middle East would clearly benefit from renewed distrust between the region's two most influential powers.

There is also the Israeli dimension. Since the outbreak of the Gaza conflict, the Houthis have repeatedly declared that their maritime campaign is intended to pressure Israel by disrupting shipping linked to Israeli interests. If commercial traffic through the Red Sea becomes increasingly constrained, Israel's trade routes could face significant economic and logistical challenges. However, if the pattern of attacks shifts from Israeli-linked shipping toward Saudi-linked vessels, analysts will inevitably ask whether the conflict is being redirected by actors pursuing broader geopolitical objectives.

History suggests that great powers compete not only for natural resources but also for the routes that transport them. The struggle is no longer confined to controlling oil fields. Increasingly, the ability to influence strategic maritime corridors has become a source of geopolitical leverage. Disrupting a major shipping route can impose economic costs on multiple countries simultaneously without direct military confrontation.

Whether the current tensions represent an extension of the Israel-Houthi conflict, an attempt to derail Saudi-Iranian reconciliation, or a broader contest for influence over global shipping corridors remains an open question. What appears increasingly clear is that in today's interconnected world, strategic power lies not only beneath the ground in oil reserves but also on the sea lanes that connect continents.

The nation—or coalition—that can influence these maritime arteries possesses a powerful instrument of geopolitical leverage. In the twenty-first century, control of shipping corridors may prove even more valuable than control of the cargo itself.
