U.S.–China crude oil trade and finished-diesel continuity
United States and China
What happened?
On April 10, 2025, the U.S. Energy Information Administration reported that U.S. crude oil exports to China fell to an average of 217,000 barrels per day in 2024, down 53% from 2023. On March 10, 2026, EIA reported that 2025 exports to China had fallen another 89% compared with 2024. EIA separately tracks distillate fuel oil, a category that includes diesel and other fuel oils. A crude export and a delivery of usable finished diesel are different events in the supply chain.
How could the hypotheses work together?
- Economic Interdependence. Share a narrow, authorized record of delayed or canceled civilian cargo so U.S. shippers and Chinese receivers can check the same status and decide independently.
- Energy Continuity. Test whether earlier confirmation changes the timing of local decisions about usable finished fuel for essential civilian services.
- Sovereign Autonomy. Check whether each operator can use local inventories and continue its own verified reporting if the shared channel stops.
What outcome could we estimate?
Fictional one-day diesel exercise: 180 barrels of usable finished diesel are in stock, 50 more barrels are confirmed received, local demand is 240 barrels, and delivery capacity is 200 barrels. The ceiling is min(230 available, 240 demanded, 200 deliverable) = 200 barrels, leaving 40 barrels of demand unmet and 30 barrels in stock. All three arrangements have the same ceiling on equal physical inputs. A crude-oil offer never enters this diesel calculation.
The export figures describe observed crude trade from one supplier to one destination. They do not establish a finished-diesel shortage, attribute the trade change to a single policy, or establish a historic MAR outcome. The fictional ledger estimates a civilian delivery ceiling under stated assumptions.
What evidence would we need?
- Record crude cargo separately from finished-product receipts. Require a dated record of product grade, accepted quantity, actual receipt and usable volume before adding a delivery to the finished-fuel ledger.
- Compare eligible records, confirmed receipt time, unmet demand and human review effort at the same starting stock, demand and delivery limits. If a process appears faster, verify whether usable fuel became available earlier under the same evidence standard.
- Document both sides’ operational gains and burdens in their own units, including time to resolve a disputed cargo notice and the service each can sustain through a channel outage.
