Asian refiners are changing the physical way they buy crude as tanker freight approaches levels that can overwhelm normal oil-price differentials. About 80 VLCCs are tied up in Middle East shuttle operations around the Strait of Hormuz, according to Vitol’s Asia head Kieran Gallagher, helping push U.S.-to-Asia transportation costs to roughly $40 per barrel. Refiners are responding with smaller Aframax tankers, longer-term vessel charters and delivered Middle East purchases that leave producers responsible for arranging freight. Taiwan’s CPC bought six Aframax cargoes in one week instead of its usual two to three VLCC purchases per month, while South Korea’s SK Energy chartered an Aframax for a U.S. crude cargo. The shift does not mean Aframaxes have suddenly become cheaper per barrel. In some fixtures their per-barrel freight is almost as expensive as VLCC freight. Their advantage is that they give refiners access to smaller, more available parcels when the normal 2-million-barrel VLCC system is severely constrained.
Asian Crude Procurement · October 2026
The 2-Million-Barrel Parcel Is Losing Its Cost Advantage
VLCCs normally win on scale. Today the vessel itself has become scarce enough that refiners are willing to split crude purchases into several smaller ships to secure physical supply and avoid competing directly for the tightest tonnage.
U.S. Gulf → Asia
$40
freight per barrel
A 2-million-barrel VLCC voyage can therefore carry an approximately
$80 million freight bill before the crude itself is paid for.

Why Go Smaller If Aframax Freight Is Not Much Cheaper Per Barrel?
VLCC
~2.0M barrels
Maximum scale efficiency in a normal market, but currently exposed
to the most acute vessel shortage and record-high spot freight.
VS
Aframax
~600K barrels
Smaller parcel and normally worse unit economics, but more flexible,
easier to source and useful when refiners cannot secure an acceptable VLCC.
Taiwan CPC
6 Aframaxes
Traders say CPC bought six Aframax cargoes in a single week rather than
its normal monthly purchase of two to three VLCC cargoes.

SK Energy
$23M Aframax
Samos was reportedly fixed to load U.S. crude in early November.
Implied Unit Freight
~$38/bbl
$23M divided by 600,000 barrels, illustrating that the smaller ship is about availability and flexibility, not cheap freight.
The Aframax shift is not a return to cheap shipping.
Reuters says Aframax and VLCC freight per barrel have moved close enough
that some refiners are willing to surrender the VLCC's normal scale advantage.
The smaller tanker mainly gives the buyer more ways to assemble supply.
The New Refiner Procurement Playbook
Buy a Smaller Ship, Lock the Ship Up Longer, or Make the Producer Deliver It
Refiners are not solving one freight problem with one substitute. They are changing vessel size, charter structure and crude-sale terms simultaneously.
Option 1
Break the Cargo Up
Replace one 2-million-barrel VLCC parcel with several approximately
600,000-barrel Aframax parcels when smaller ships are easier to obtain.
Option 2
Time-Charter the Tonnage
Refiners with vessels already on long-term charter are less exposed
to the full spot-rate spike each time they need a cargo moved.
Option 3
Buy Delivered Crude
ADNOC and Saudi Aramco are selling some Asian cargoes on delivered terms,
leaving the producer responsible for arranging the expensive transportation.
How the freight shock is changing crude selection← →
| Strategy / Market | Current Change | Freight Logic | Who Carries the Risk? | Market Effect | Key Limitation |
|---|---|---|---|---|---|
| Aframax ParcelsSmaller tanker workaround | Asian refiners are splitting some purchases into roughly 600,000-barrel parcels. | Creates access to a different vessel pool when VLCC tonnage is exceptionally tight. | Buyer still normally carries freight unless commercial terms shift. | Raises demand for Aframax tonnage and reduces the absolute exposure to any one giant fixture. | Per-barrel freight can be nearly as expensive as VLCC freight and multiple ships create more operational complexity. |
| Long-Term ChartersPre-secured vessel access | Asian refiners are leaning more heavily on tanker capacity already leased under term arrangements. | Reduces repeated exposure to the extreme spot market. | Depends on charter structure, but vessel availability has effectively been pre-booked. | Increases strategic value of controlled tonnage rather than relying entirely on voyage-charter fixtures. | Existing long-term rates may still be costly and the charterer carries utilization risk when the market eventually falls. |
| Delivered Middle East CrudeSeller arranges freight | ADNOC has offered coming cargoes delivered to China and India; Saudi Aramco has also sold delivered barrels to Asian buyers. | Producer uses its own logistics capability or tanker access instead of forcing the refinery into the spot market. | Producer assumes the shipping task and prices it into the delivered crude offer. | Could strengthen integrated Gulf producers that control oil supply plus transport capacity. | The freight expense does not disappear. It moves into the producer's delivered-price calculation. |
| U.S. CrudeLong-haul arbitrage squeezed | Freight near $40/bbl has sharply reduced Asian appetite for U.S. Gulf cargoes. | A long voyage magnifies the value of every scarce tanker-day. | Depends on sale terms, but FOB buyers are heavily exposed to transport cost. | U.S. sellers face pressure to discount crude enough to compensate for shipping. | Supply-security needs can still keep some Atlantic crude moving even when the pure arbitrage appears closed. |
| West African CrudeDiscounts widen | Some spot differentials reportedly fell as low as roughly minus $20/bbl. | Seller must offset the cost of a long voyage to keep the barrel competitive in Asia. | Commercial burden is shared through lower crude pricing and higher freight. | Physical shipping costs begin feeding directly back into the commodity's origin differential. | Discounts can recover rapidly if tanker availability normalizes. |

The Bigger Structural Shift
Freight Risk Is Moving Upstream
When refiners buy delivered barrels, integrated producers with crude supply,
tanker access and logistics networks take responsibility for solving the transport problem.
ADNOC
Delivered China + India
Traders say cargoes loading over the next two months have been offered on delivered terms.
Saudi Aramco
Delivered Asia
Also sold next-month cargoes with shipping arranged by the producer.
Asian Buyer
Less Spot-Tanker Exposure
Refinery receives a delivered barrel without separately fixing a vessel at record spot levels.
Producer
More Logistics Exposure
Freight risk is internalized by the seller and becomes part of crude pricing and fleet strategy.

Scenario Result
VLCC Cheaper, Aframax More Flexible
At the entered rates, the VLCC still produces a lower total freight bill.
Refiners may nevertheless choose smaller ships when prompt VLCC capacity is unavailable
or when parcel flexibility has greater operational value.
Scenario model only:
real fixtures depend on loading dates, ballast position, port restrictions,
bunker costs, war-risk premiums, demurrage, cargo compatibility, charter terms
and whether the quoted tanker is actually available. Smaller tankers can carry
less than their nominal maximum on specific routes. The default $23 million Aframax
fixture is a reported individual transaction and should not be treated as a market average.
