Introduction
Five Cents examines The Energy Shock’s Second Phase: why a disruption that began with crude supply is now hitting diesel, jet fuel, freight, inflation and household budgets. We’ll separate the physical constraints already visible from the market assumptions that could still change the outlook. The place to start is the buffer that made the first phase manageable.
What is happening
An energy shock becomes more dangerous when the system stops absorbing it through inventories. Lost production can initially be covered by emergency reserves, commercial tanks, oil already at sea and alternative routes. But those are different buffers, and none is unlimited. By August, global oil production had fallen sharply, with more than ten million barrels a day of Gulf output still shut in. Global inventories had also dropped by ninety-five million barrels in that month alone, extending a much larger draw since February.
Oil held on tankers fell too. That is a sign that disrupted shipping is reducing flexibility before storage facilities are empty. That matters because reopening a route is not the same as restoring supply. Tankers need security cover and insurance. Refineries need the right crude, working equipment and available storage. Importers need cargoes delivered on time.
Each delay keeps pressure on prices, even if the fear of an immediate shortage eases. The second phase is therefore less about the headline price of crude and more about refined fuels. Diesel sits inside trucking, farming, construction, shipping, mining and backup power. When diesel is scarce or expensive, the cost spreads through food, parcels, building materials and public transport.
Recent falls in diesel exports from Russia, the Middle East and Asia have tightened a market that was already sensitive to low inventories. Jet fuel has its own constraints. It must meet strict technical specifications, and airlines cannot quickly substitute another energy source. Lower exports from major supplying regions raise operating costs. That can feed into fares, fuel surcharges and reduced capacity on marginal routes.
The consequence is uneven. Remote regions, lower-income travellers and businesses reliant on regular air links feel it first. Shipping is the invisible multiplier. When vessels avoid a risky route, effective fleet capacity shrinks. Longer voyages tie up ships for more days, insurance premiums rise and freight rates climb.
Some alternative routings can more than double journey times
Some alternative routings can more than double journey times. That raises the delivered price of fuel and leaves fewer vessels available elsewhere. In other words, tanker costs are part of the supply problem, not a side story. High prices eventually curb demand. Households combine trips or drive less. Airlines trim capacity. Freight firms consolidate loads. Factories reduce output.
That can slow further price rises, but it is not a healthy correction. It is demand destruction: the market balancing because activity and purchasing power are weakening. This is where the energy shock becomes an inflation and growth problem. The first effect is direct: more expensive fuel, heating, transport and flights. The second arrives through production and logistics, as diesel raises the cost of moving goods and operating machinery.
A third round becomes possible if firms pass costs through and workers seek compensation for lost purchasing power. That final step is not automatic. It depends on wage-setting, fiscal support, exchange rates and, above all, whether people expect inflation to stay high. Central banks face an awkward choice. They can look through an initial energy shock, because higher interest rates cannot reopen a shipping lane.
But if inflation expectations drift upwards or currencies weaken, delaying action risks more persistent price growth. Raising rates, meanwhile, can protect credibility and currencies while worsening debt burdens, housing pressure and investment. The burden is most acute for energy-importing economies with weak currencies, limited foreign-exchange reserves, large debts or broad fuel subsidies.
Their import bills rise, currencies can fall, and fuel becomes even more expensive in local terms. Governments then face a difficult choice between costly support and higher consumer prices. Even oil exporters are not automatically protected if their export routes, infrastructure or refined-fuel imports are disrupted.
So the facts and forecasts need to stay separate
So the facts and forecasts need to stay separate. Production shut-ins, inventory draws, weaker refinery runs and higher freight costs are present constraints. A recovery in Gulf output, normal tanker traffic, lower demand and contained inflation are conditional outcomes. They may happen, but they depend on security, logistics and confidence recovering together.
The key point is that this is no longer just an oil-price story. It is a bottleneck story: depleted buffers, constrained refining and slower shipping can turn a regional disruption into higher costs across the global economy. And lower demand may signal damage, not relief. To explore this further, you can generate Five Cents episodes on Diesel: The Hidden Inflation Engine and Central Banks After an Energy Shock.
