Freight has become a central part of the oil price equation. A shortage of available Very Large Crude Carriers (VLCCs)—the tankers commonly used for cargoes of roughly two million barrels—means crude is taking longer and costing far more to reach buyers. Reported Houston-to-Asia freight of about $26 per barrel, or $52 million per cargo, is roughly one-quarter of the price of West Texas Intermediate futures. 6
The key is that this is an effective-capacity shortage. The global fleet has not vanished, but disruption around the Strait of Hormuz, waiting time, shuttle operations and longer replacement routes are using up more ship-days for every barrel delivered. Until those vessels are released or new ships arrive, expensive freight can reshape crude trading and refinery buying.
Tankers are productive only when they can complete voyages and return for the next cargo. If a vessel is delayed, diverted, or employed in shorter shuttle legs tied to constrained export infrastructure, it cannot simultaneously serve a long-haul route. Likewise, replacing disrupted Middle Eastern supplies with Atlantic Basin barrels for Asian buyers lengthens the average voyage and absorbs additional tanker days.
That is the mechanics of a ton-mile shock: demand for vessel time rises even if the number of barrels consumed does not increase materially. During the height of the Hormuz disruption, traffic through the strait fell by more than 90% from a pre-conflict level of roughly 90–110 vessel transits a day. Traffic later began recovering, but remained below pre-crisis norms and vulnerable to reversals. 1
The available fleet is also unevenly distributed. The Signal Group reported that laden VLCC availability east of Suez was down 36% year on year, to 122 vessels on a 30-day average in early September. 10 In a market where a single cargo can occupy a ship for weeks, that reduction can have an outsized effect on freight.
A refiner does not buy crude based solely on the headline price at the export terminal. The relevant figure is the delivered cost: crude price plus ocean freight, insurance, finance, port charges and the risk of delays.
At about $26 per barrel, shipping a two-million-barrel cargo from Houston to Asia adds approximately $52 million before other costs. 6 The spread between a U.S. Gulf Coast grade and a competing Asian or Middle Eastern grade must be wide enough to cover that freight burden. Where it is not, the trade is likely to be deferred or replaced with nearer supply.
That does not mean every long-haul cargo stops moving. Buyers may still pay high transport costs when a particular crude grade fits their refinery configuration, when local alternatives are scarce, or when the price differential is unusually wide. But high freight raises the threshold for each transaction and removes the marginal deals that normally help balance regional oil markets.
When transport is scarce or unpredictable, refiners have a strong incentive to prioritize crude that is closer, available now and less exposed to disruption—even if it is not their preferred grade.
This can produce several effects:
The consequence is a less efficient global matching of crude quality, refinery capability and location. Oil may still exist on paper, but it cannot necessarily move to the refinery that can process it at the lowest cost.
The tanker squeeze does not directly remove barrels from the ground. It constrains how rapidly and reliably those barrels can reach a refinery. Delayed cargoes, unreliable deliveries and grade mismatches can complicate refinery scheduling and reduce the ability of refiners to respond quickly to regional shortages.
This is why an oil-shipping disruption can amplify fuel-market stress. If refineries cannot obtain suitable crude on time, the eventual impact can extend beyond crude differentials to regional balances for gasoline, diesel and jet fuel. The size of that effect depends on the duration of disruptions, inventories, refinery flexibility and the availability of alternative routes; it should not be assumed that every freight spike produces an equal rise in retail fuel prices.
For tanker operators, the same scarcity that burdens cargo buyers raises the earning power of available ships. Reuters reported in June that Gulf tanker hire costs had nearly doubled amid the disruption and that operators were earning record profits. 3
Higher spot earnings can also support vessel and company valuations because investors may expect a period of unusually strong cash flow. The Signal Group indicated in February that a five-year-old VLCC was valued above $120 million, about 17% higher year on year. 30 Those valuations remain sensitive to freight rates: if routes normalize and vessel utilization falls, the premium could unwind.
Shipowners are responding aggressively. Reuters reported that 2026 VLCC orders had already surpassed twice the full-year 2025 total: Signal Group counted 217 orders, while Allied Shipbroking counted 164, reflecting differing datasets. The buying wave exceeds $20 billion and is the largest in at least 25 years. 17
But ordering a tanker is not the same as receiving one. Around 83% of the VLCCs ordered in the first half of 2026 are scheduled for delivery in 2028 and 2029. 23 The current orderbook is therefore unlikely to add meaningful immediate capacity while ships are still being tied up by disrupted trade patterns.
This delayed supply response creates a two-sided risk:
The cleanest way to understand the shortage is to look beyond the fleet count. What matters is how many days of VLCC capacity are required to move each barrel from seller to refiner.
Normal, dependable Hormuz access and shorter sailing patterns reduce that requirement and release ships back into the market. Continued uncertainty does the reverse. The record orderbook matters for the later part of the decade, but near-term freight will be determined primarily by route reliability, voyage duration, vessel availability and whether disrupted Middle Eastern exports can resume predictable flows.
For oil buyers, the practical implication is clear: the cheapest barrel at the loading terminal is not necessarily the cheapest barrel at the refinery. In a constrained tanker market, freight has become a decisive part of the crude trade. 6
