The Sky News report on Iran threatening to block another major global trade route should not be read as an isolated escalation. It is better understood as the logical continuation of a strategy that has already been partially demonstrated: the weaponisation of the world's narrow maritime chokepoints. What is at stake is not simply regional conflict, but the vulnerability of the entire global trading system to disruption at a handful of geographic bottlenecks.
The Strait of Hormuz has long been recognised as one of these bottlenecks, a narrow corridor through which a significant portion of the world's oil supply passes. Its strategic importance has been discussed for decades, but largely in abstract terms, as a theoretical risk rather than an imminent one. That abstraction has now collapsed. Even limited interference in Hormuz is enough to send shockwaves through energy markets, disrupt shipping patterns, and trigger immediate economic anxiety. The strait is not just another route; it is an artery. And once one artery is constricted, attention inevitably turns to the others.
The second critical passage, increasingly in focus, is the Bab el-Mandeb Strait—the so-called "Gate of Tears"—which links the Indian Ocean to the Red Sea and, by extension, the Suez Canal. If Hormuz is the tap controlling Gulf energy exports, Bab el-Mandeb is the conduit through which much of that energy, and a vast volume of global trade, flows toward Europe. The two are not independent. They form part of a single system. Disrupt both, and the consequences are not additive but multiplicative. Ships are forced into long detours around Africa, supply chains stretch and fray, costs rise sharply, and delays cascade through industries that depend on just-in-time logistics.
What this reveals, more clearly than any academic discussion of globalisation ever could, is how fragile the system actually is. For decades, policymakers and economists have operated on the implicit assumption that global trade routes are stable, neutral, and effectively guaranteed. This assumption underpinned the expansion of complex, geographically dispersed supply chains and the steady integration of markets. But that stability was never a law of nature. It was a contingent political and military achievement, maintained by a particular balance of power. As that balance shifts, so too does the reliability of the system it supported.
Iran's threat, whether fully realised or not, exposes a broader transformation in the nature of power. It is no longer necessary to defeat an adversary's military in the conventional sense. It may be sufficient to disrupt the flows on which that adversary depends. A narrow stretch of water, if strategically positioned, can exert leverage disproportionate to its size. Control over geography, over chokepoints rather than territories, becomes a decisive instrument.
There are, of course, alternatives. Oil can be moved via pipelines that bypass Hormuz, and ships can reroute around the Cape of Good Hope if the Red Sea becomes too dangerous. But these alternatives are limited in capacity and costly in practice. Pipelines cannot absorb the full volume of maritime transport, and rerouting adds weeks to journeys, increases fuel consumption, and raises insurance costs. These are not substitutes so much as emergency workarounds, capable of alleviating pressure but not restoring normality.
If such disruptions remain short-lived, the global economy absorbs the shock, albeit with higher prices and temporary dislocation. But if they are sustained, the effects deepen. Energy prices rise, feeding into inflation. Supply chains begin to seize as delays compound. Industrial production slows. Governments are forced to intervene, whether through subsidies, rationing, or direct control of resources. What begins as a logistical problem becomes an economic one, and then a political one.
In the longer term, the implications are more profound still. A sustained breakdown in key trade routes would accelerate a shift already underway: the partial unwinding of globalisation. States would move to secure more local or regional sources of energy and production, not because it is efficient, but because it is reliable. Trade would not disappear, but it would reorganise into blocs, each seeking to insulate itself from external shocks. The open, interconnected system of the late twentieth and early twenty-first centuries would give way to something more fragmented and more defensive.
What makes this moment particularly striking is how poorly anticipated it was by the intellectual and policy class that presided over the era now ending. For decades, interdependence was treated as a stabilising force, something that would reduce the likelihood of conflict by raising its costs. Trade routes were assumed to be permanent features of the landscape, part of the background rather than objects of contestation. The possibility that they might themselves become targets — central levers in geopolitical struggle — was acknowledged in theory but largely ignored in practice.
The result is a kind of conceptual lag. The world has changed faster than the frameworks used to understand it. What we are witnessing is not simply a regional crisis, but the exposure of assumptions that no longer hold. The smooth surface of globalisation, once taken for granted, is beginning to fracture along its weakest lines.
If the Strait of Hormuz is constrained, the system strains. If the Bab el-Mandeb is also compromised, the strain intensifies. And if multiple chokepoints are disrupted simultaneously, the system does not merely bend — it risks breaking. The arteries of global trade, once assumed to be permanently open, are now visibly vulnerable. And once that vulnerability is recognised, it cannot be unseen.
