Introduction
Five Cents Oil shortages test trade looks at why this is not simply a question of running out of oil. It is about getting diesel, jet fuel, and ship fuel through unsafe routes and into the right markets. We’ll trace the pressure on Gulf exports, Russian refining, tanker costs, and the knock-on effect for freight, food, and industry. The best place to start is with the difference between crude oil and the fuels that keep trade moving.
Crude is the raw material
Crude is the raw material. It can be stored, blended, and, in some cases, rerouted. Refined products are less flexible. Diesel has to meet local specifications, come from available refineries, and reach buyers on specialised tankers. Marine fuel faces a similar problem. Ships need it where they are, not weeks later on the other side of a disrupted route.
That is why a market can have oil available somewhere and still experience a serious shortage elsewhere. The immediate stress is concentrated in flows: reduced refinery exports, delayed cargoes, constrained tanker capacity, and higher insurance costs. For importers, the question is not just whether a barrel exists. It is whether it can arrive safely, on time, and at a price they can absorb.
The Strait of Hormuz is central because it connects Gulf producers with global buyers. Flows are still moving, but security risks have severely limited normal traffic. Some crude can bypass the strait through pipelines or travel under military protection. Yet those alternatives cannot fully replace a major maritime corridor.
Further west, insecurity around Bab el-Mandeb and the Red Sea adds another layer. A ship avoiding those waters may travel around southern Africa instead of using the Suez route. That means more days at sea, more fuel burned, fewer ships available for other cargoes, and higher freight bills. A disruption in oil shipping can therefore raise the cost of transporting almost everything else.
The squeeze is particularly sharp for diesel and other middle distillates. Gulf exports of refined products have fallen far more steeply than crude flows. Disruption to Russian refineries and product exports has removed another important source of supply. Refiners are also favouring higher-value fuels over fuel oil. That tightens the market for bunker fuel used by ships and, in some places, power plants.
That creates a chain reaction
That creates a chain reaction. Shipping companies pay more for fuel, insurance, and longer voyages. Traders send available cargoes to the markets offering the highest prices. Ports receive irregular arrivals instead of predictable deliveries. Trucking, farming, construction, mining, and backup power all compete for diesel, often at the same time.
The effects will be uneven. Parts of Asia are highly exposed to reduced Gulf supplies and expensive marine fuel. European buyers may draw replacement diesel from the United States or Asia. That can leave other importing regions bidding harder for the same cargoes. The United States can export crude and refined products, but it also faces low distillate inventories and seasonal demand from transport, agriculture, and heating.
For lower-income, import-dependent economies, the risk is sharper still. Governments may have less capacity to subsidise fuel, while businesses cannot always pass rising costs on to customers. Higher diesel prices can quickly affect food distribution, bus services, electricity generation, and basic goods.
Headline crude prices matter, but they do not tell the full story. Inventories have fallen and production remains constrained, pushing crude prices higher. Yet refined products can rise faster because they depend on more specific infrastructure. A country may not face an empty petrol station tomorrow, but it can still see more expensive freight, delayed deliveries, and pressure on diesel-dependent sectors.
There are ways to ease the strain, though none work overnight. Safer and more reliable transit through Hormuz and Bab el-Mandeb would reduce risk premiums. Gulf refinery exports need to recover, not just crude output. Alternative pipelines and land routes can help at the margins. Strategic stock releases may cushion supply, but crude reserves cannot instantly replace missing diesel or marine fuel. And refinery repairs in Russia would matter directly to the global diesel balance.
The key signals now are tanker movements
The key signals now are tanker movements, insurance and freight rates, Gulf exports of diesel and jet fuel, Russian refinery operations, and the pace of inventory drawdowns. Diplomatic progress could calm prices quickly, but restoring physical trade patterns would still take months. The central lesson is that global trade is being tested by several linked bottlenecks at once: unsafe routes, reduced refining, scarce ships, and thin inventories.
The shortage is regional and product-specific, but its costs can spread widely through transport and everyday goods.
