Iranian Crude Sold at Discount to China as May Arrivals Drop to Over One-Year Low
Miles Bennett
Iranian crude flipped from a premium to a discount of over $1/barrel versus ICE Brent in a single month, with May shipments to China falling to 1.1 million barrels/day — the lowest since January 2025. Chinese independent refiners, squeezed by losses and US sanctions, are pulling back hard enough to drag Russian crude premiums down with them.
How Did the Price Flip So Fast?
Iranian crude offers to Chinese buyers — benchmarked to ICE Brent — carried a premium last month but now sit at a discount of over $1/barrel.
This means → sellers went from "mark it up, they'll still buy" to "cut the price or it doesn't move." The buyer's market flipped overnight.
Russian Far East export crude prices have dropped in tandem. Two major supply sources cutting prices at once is no coincidence.
How Much Have Arrivals Fallen?
Vessel-tracking firm Kpler puts Iranian crude flows to China at 1.1 million barrels/day in May — the lowest since January 2025.
Roughly 56 million barrels of Iranian crude now sit in floating storage globally, with over 60% of those tankers anchored near the Singapore Strait and off China's coast.
In plain terms = the oil can't find a buyer, so it floats at sea. A large fleet of tankers is effectively parked, waiting.
Why Are Chinese Independent Refiners Not Buying?
China's independent refiners — known as "teapots" — typically handle about 90% of Iran's crude sales. They are the single most important buyer group.
Two pressures are hitting at once: refining margins have narrowed or turned negative → refiners are voluntarily cutting run rates; US sanctions keep escalating → the latest target is major independent refiner Hengli Petrochemical (Dalian).
This means → on one side, "refining loses money"; on the other, "buying risks penalties." Teapots are trapped on both flanks, and purchasing appetite collapses accordingly.
Will Beijing Change Its Stance?
Bloomberg reports that Beijing had previously ordered refiners to secure fuel supplies at all costs to buffer against Middle East conflict risks.
As refiner losses widen, however, that directive is expected to be relaxed.
In plain terms = the government said "you must refine." Now the losses are too large for Beijing to keep pushing.
What Does the Russian Crude Drop Signal?
Russia's flagship ESPO blend — its main crude export to Asia via the East Siberia–Pacific Ocean pipeline — saw its premium to ICE Brent compress from about $6/barrel last month to $3/barrel, a halving.
The driver is the same: thin buying from Chinese teapots.
This reflects a structural pressure point. Teapot weakness is not an Iran-only story — it now weighs on the entire discounted-crude market in Asia. Whether teapot run rates recover is the key variable for the next round of supply-demand rebalancing.
