Several weeks into a cascading energy shock, a sobering reality is coming into view. Today’s oil shortages owe less to geology than to geography. Roughly 500m barrels that would normally have reached refineries and consumers have failed to appear. The cause is not a single rupture but a convergence. Russian exports are impaired, Iran is newly entangled, and tanker traffic through the Persian Gulf has become hazardous.
The result is a crisis spreading faster than policymakers can respond, hitting regions unevenly but with growing force.
Asia’s early descent into scarcity
Asia has felt the first and sharpest impact. The last prewar cargoes from the Gulf have arrived, and replacement flows have slowed to a trickle. Rationing is already in place in New Zealand, Thailand, Taiwan, the Philippines, and Vietnam. South Korea, heavily reliant on imports and short on alternatives, looks particularly exposed.
India has avoided a classic crude shortage by absorbing what remains of Gulf supply and taking advantage of newly permissible Russian barrels. Yet it faces a different kind of emergency. About half its population relies on LPG sourced from the Gulf, and those shipments have fallen to zero. The result is a household crisis that is more immediate than any increase at the pump.
China, true to form, has insulated itself by curbing exports of refined fuels. Years of excess refinery capacity, once criticized, now serve as a buffer. But that choice carries consequences for others. Importers such as Australia and New Zealand, once dependent on Chinese products, now face a second shock as those supplies disappear.
Europe’s grace period is ending
Europe has enjoyed a brief reprieve, but it is fading. The final prewar Gulf cargoes are landing just as Ukrainian strikes on Russian export infrastructure begin to take effect. Europe’s workaround, importing Russian crude indirectly through third countries, will soon unravel. By early summer, the continent risks losing access to both Russian and Gulf supplies.
The timing is difficult. Industry is already strained by high power costs and weakening competitiveness. Another energy squeeze threatens to deepen those weaknesses.
A Gulf turning into a one way valve
Tanker traffic through the Gulf has fallen to roughly 15% of normal volumes. Iran has effectively set up a toll system, escorting vessels for a fee. Oman has followed with a similar approach, allowing ships to reflag and pass under its protection. For now, Iranian forces have avoided targeting Omani flagged vessels, creating a narrow outbound corridor.
Inbound traffic, however, is limited. Storage tanks are filling. Without ships to load, producers will soon have little choice but to shut in output. Even intact fields cannot operate indefinitely without somewhere to send their oil.
Sanctions undone by necessity
In an effort to keep oil moving, the United States has effectively relaxed sanctions on Russian and Iranian cargoes already at sea. Years of diplomatic effort have been weakened in a single move. Rebuilding a sanctions regime later will be harder, especially as enforcement credibility has diminished.
At the same time, physical damage to Russian infrastructure continues to restrict supply beyond the shipping disruptions.
A new geopolitical geometry
The ironies are striking. A campaign meant to constrain Iran has made its oil acceptable again. China’s refinery overcapacity has shifted from inefficiency to advantage. Europe’s dependence on imports, long acknowledged but often ignored, is now a central vulnerability.
The global energy system is not collapsing. It is being reshaped quickly, and with little room for adjustment.
Four horizons
One month: a price shock with political overtones
Oil and fuel prices rise sharply, with volatility tied to each new disruption. Rationing deepens in Asia, while Europe begins to feel tightening supply. Inflation moves higher, driven by transport and food. Financial markets grow cautious, and fuel importing emerging economies see credit spreads widen. Governments rely on strategic reserves and subsidies to buy time. The crisis is visible but not yet systemic.
Three months: industrial strain and demand destruction
Refineries in Europe and Asia begin cutting runs as crude becomes scarce. Strategic reserves thin, and prices remain elevated. Energy intensive sectors such as chemicals, metals, and autos reduce output as margins come under pressure. Global growth slows, and several import dependent economies edge toward recession. Central banks face a familiar choice between tolerating inflation and tightening into weakness. The shock spreads beyond energy into the wider economy.
Six months: structural adjustment and regional divergence
As storage fills, Gulf producers are forced into shut ins. Non Gulf suppliers accelerate investment, but new supply takes time to arrive. Trade routes lengthen, embedding higher transport costs into prices. Europe and parts of Asia face sustained industrial contraction, while North America and some producers in Africa and Latin America gain relative advantage. Energy security becomes a guiding principle of policy.
One year: a reordered energy map
Oil and LNG prices settle into a higher structural range. New infrastructure such as pipelines, export terminals, and storage expands outside the Gulf. Demand adjusts through efficiency, electrification, and substitution. Global growth remains subdued and uneven. Geopolitical blocs harden as energy flows align more closely with political alliances.
By then, the disruption will no longer feel temporary. The world will have adjusted to a new reality where the Persian Gulf is no longer a dependable artery of global energy.
