20 million barrels a day: Geography drives Gulf oil

Every day, approximately twenty million barrels of crude oil transit through a single waterway thirty-four kilometres wide and sixty metres deep. That volume represents roughly one-fifth of global oil consumption. Alongside it flows roughly a quarter of the world’s liquefied natural gas, destined overwhelmingly for China, Japan, India, the EU and South Korea.
A tanker passes every few minutes. Nearly one hundred vessels a day. The energy that heats Asian homes, powers Chinese factories and fuels Indian industry funnels through this narrow passage between two shorelines. When that passage is disrupted — as it now is — the consequences are not regional. They are global.
But the deeper question is not about the current disruption. It is about what happens next. Maritime chokepoints have been contested throughout recorded history and this strait has been threatened or instrumentalised in nearly every Gulf crisis of the past four decades. What changes is the trigger; what remains constant is the vulnerability. For nations whose economies depend on uninterrupted passage through a waterway they do not fully control, the question is no longer whether disruption will recur. It is how to build an economic architecture that functions even when disruption occurs.
Classical economics identifies four factors of production: land, labour, capital and enterprise. For most of the twentieth century, Gulf economies understood ‘land’ primarily as what lay beneath it — hydrocarbons. The surface was incidental; the subsurface was everything. But the current crisis demands a fundamental reassessment. Land is not merely a repository of natural resources. It is location. It is connectivity.
It is the physical position of a nation relative to the trade routes, the ports, the rail corridors and the logistics networks that determine whether goods, energy and people can move freely. In a world where maritime passages can be closed in hours, the geography above the ground — the roads, the railways, the ports that sit outside chokepoints, the overland corridors that connect producer to consumer without depending on a single strait — becomes the most consequential factor of production a nation possesses.
This is not theoretical. The alternative infrastructure either already exists or is under construction. Rail corridors now connect Gulf ports to hinterland markets by land. Deep-water port complexes on the Arabian Sea provide access to the Indian Ocean without transiting any chokepoint. Multimodal logistics networks link the Gulf to the Red Sea, East Africa and the Indian subcontinent through routes no single state can blockade. The engineering and commercial logic for chokepoint-free trade corridors is already established. What has been absent is the collective will to prioritise them — and a sufficiently visceral demonstration of why they matter. That demonstration is now underway.
The case for regional collaboration has never been more compelling. The Gulf Cooperation Council was founded on the principle that collective economic security is stronger than individual vulnerability. That principle has never been tested as directly as it is today. When pharmaceutical supply chains serving sixty million citizens are hostage to a single waterway; when food imports depend on passage through contested waters; when insurance premiums surge overnight and shipping lines suspend operations — the response cannot be national. It must be regional and it must be structural.
What does structural resilience look like? It looks like accelerated investment in rail corridors connecting Gulf ports to Gulf markets by land. It looks like shared pharmaceutical and food strategic reserves at facilities on the Arabian Sea that no blockade can reach. It looks like cold-chain logistics enabling temperature-sensitive medicines to move by rail between GCC capitals in hours. It looks like trade agreements — such as the recently ratified India–Oman Comprehensive Economic Partnership Agreement (CEPA), with near-complete tariff elimination — that create direct corridors between Gulf producers and Asian consumers, independent of any chokepoint. And it looks like a GCC-wide commitment to treating supply chain resilience as sovereign infrastructure — as essential as defence, yet far less costly to build.
There is a further dimension that deserves candid acknowledgement. The nations whose economic infrastructure has proven most resilient during this crisis are not the most militarised. They are the most diplomatically balanced. Neutrality — genuine, consistent, institutionalised neutrality — has demonstrated its value not merely as a diplomatic posture, but as an economic asset. Jurisdictions that maintain constructive relationships across all geopolitical axes, that invest in mediation rather than confrontation, have emerged with their ports operational, their airspace open and their credibility intact. That is not coincidence. It is strategy. And it is a strategy the entire Gulf would benefit from studying.
Three questions now confront Gulf policymakers. First: can the GCC develop a unified narrative for collective economic security — one that treats supply chain resilience, energy logistics, pharmaceutical reserves and food security as shared sovereign infrastructure rather than national concerns? Second: can the Gulf’s producers and Asia’s consumers build a joint investment framework for the rail corridors, the Arabian Sea port capacity and the multimodal logistics networks that would make this resilience permanent — a framework in which China, India, Japan, South Korea and the European Union are not merely customers, but co-architects of a new Indian Ocean trade system? And third: can Oman play the convening role required for such an effort, given its geographic position at the junction of these corridors, its diplomatic credibility trusted by all parties and its institutional readiness to lead such cooperation?
The answer to the third question is not a matter of aspiration. It is a matter of geography, of infrastructure already built, of trade agreements already signed and of a diplomatic tradition already proven under the most exacting circumstances. The nation best placed to lead this conversation is the one whose ports sit on open waters, whose railways connect to its neighbours, whose trade agreements span East and West; and whose word is trusted in every capital that matters.
Geography gave the Gulf its wealth. Geography now demands that the Gulf reimagine how that wealth moves. The factors of production have not changed since Adam Smith enumerated them. But our understanding of which factor matters most — and which nation is best positioned to mobilise it — may be changing permanently.
