Iranian crude available to China falls to 83 million barrels afloat as US blockade bites
The pool of Iranian crude sitting outside the Persian Gulf and Gulf of Oman is down to about 83 million barrels, off from more than 100 million before the US reinstated its blockade on Iran's oil exports. Readily available cargoes for Chinese buyers have nearly run out. That matters to a US jobber even though not a drop of it lands here.
Who buys the barrels
Independent Chinese refiners, the teapots, are the biggest takers of Iranian crude, and they may have to turn to other supply as soon as next month. When those refiners lose their discounted Iranian feedstock, they don't stop running. They go shopping in the same market other refiners buy from.
The path to the rack is short. When teapots cover lost Iranian barrels with Russian, West African, or Middle East grades, they pull those cargoes off the water and firm up the global crude price that sets Brent and WTI. Rack diesel and gasoline take their cue from that print. A jobber isn't exposed to Iran. A jobber is exposed to what Iran's missing barrels do to the price of everything else.
The size of the move depends on how fast the teapots have to replace volume and how much OPEC+ spare capacity steps in. Neither is settled. The 17-million-barrel drop in available Iranian crude is real and already on the books, so the tightening is underway, not a forecast.
Branded vs unbranded read
For marketers watching supply security, a firmer crude floor narrows the gap between branded and unbranded rack. When crude is soft and long, unbranded runs cheap and pulls volume. A tighter global barrel compresses that spread and takes some of the shine off unbranded arbitrage. Worth watching if you've been leaning on spot unbranded to protect margin.
The ethanol footnote
Coastal Corporation's arm secured an additional 4,310 KL ethanol allocation for Q4 of India's 2025-26 supply year. It's a domestic Indian blending story and it does nothing to a US rack or a US RIN. India buys its ethanol at home to hit its own mandate. The only reason it reaches this page is that it's the other allocation news on the wire, and it isn't competing for the same molecules US blenders use.
What to watch
Whether the teapots actually source replacement barrels next month or draw down inventory and wait. Whether OPEC+ leans on spare capacity to fill the hole, which would cap any crude firming. And whether the branded-unbranded spread at your terminal starts closing, the first place a jobber would feel a tighter global barrel before it shows up in a headline.
