Iran Oil Supply to China Is Rapidly Drying Up

Crude oil prices are holding firm even as Washington tightens the screws on one of the world's largest sellers of sanctioned barrels. The United States Oil Fund (USO) traded at 134.64 dollars on August 22, up a modest 0.07% for the day, sitting comfortably within its 52 week range of 102.42 to 142.33 and carrying a relative strength reading of 61.37 that points to steady, not overheated, buying interest.

At a Glance

• USO trades at 134.64 dollars, up 0.07% on the day, RSI at 61.37
• Iranian crude available outside the Persian Gulf has fallen to about 83 million barrels from over 100 million before mid July
• Roughly 40 million barrels sit in floating storage near Singapore, with only about 4 million barrels reportedly unsold
• Iranian Light crude now trades at a 3.50 dollar premium to Brent, a swing from a 3.50 dollar discount a week earlier
• China's independent refiners may need to lean on Russian Urals crude or fuel oil as substitutes

How does iran oil supply to china stand right now

The question of how iran oil supply to china actually functions has become central to crude markets this month. Data from Kpler shows that readily available Iranian cargoes have thinned sharply since the United States reinstated its blockade in mid July, right after talks between Washington and Tehran broke down. Total volume held outside the Persian Gulf and Gulf of Oman now stands near 83 million barrels, down from more than 100 million barrels before the clampdown.

About half of that remaining volume, close to 40 million barrels, sits in floating storage near Singapore's Eastern Outer Port Limits anchorage. Yet according to Kpler senior crude analyst Muyu Xu, market participants believe only two cargoes, roughly 4 million barrels combined, remain unsold from that stockpile. That imbalance hints at a supply cliff arriving fast.

Why the squeeze is showing up in prices

Xu noted that no laden Iranian tankers have managed to slip past the blockade, meaning buyers could see essentially no new Iranian supply for delivery from late September onward. That scarcity has already flipped the pricing picture: Iranian Light crude now commands a 3.50 dollar premium over ICE Brent, a stark reversal from the 3.50 dollar discount it carried just a week prior.

The blockade has effectively choked shipments from Kharg Island, the terminal responsible for roughly 90% of Iran's crude exports, according to analysts and vessel tracking services. President Trump added political weight to the pressure this week, describing the campaign as the most severe economic action ever taken against a nation and warning that any country offering Iran a lifeline could face what he called tremendous economic consequences. He did not name China directly, but China has purchased more than 90% of sanctioned Iranian oil in recent years, making it the obvious target of that warning.

What Chinese refiners might do next

Earlier in August, analysts had expected China's independent refiners, often called teapots, to ramp up Iranian purchases as inventories in Shandong province dropped to their lowest point this year after the steepest monthly draw in a decade. That plan now looks harder to execute. Xu suggested teapots will likely need to increase purchases of Russian Urals crude or fuel oil instead, since ESPO barrels from Russia were already sold out weeks ago. Refiners that cannot secure substitutes risk trimming throughput once existing stockpiles run low, potentially as soon as October.

Will alternative barrels fill the gap in time

The coming weeks will test whether Chinese refiners can pivot quickly enough to Russian or other supply without disrupting output. USO's steady price action suggests broader oil markets have not yet priced in a severe disruption, but the shrinking Iranian float and the political rhetoric around it leave little room for complacency.
