**Summary**: China’s Ministry of Commerce has reportedly instructed domestic companies not to comply with US sanctions on refiners linked to Iranian oil trade, including Hengli Petrochemical. This materially increases the likelihood of sustained or higher Iranian crude flows and escalates US–China friction over energy trade, with bearish implications for oil benchmarks but a higher geopolitical risk premium.

## Detail

1) What happened:
China has reportedly directed domestic companies not to comply with US sanctions targeting Chinese refiners involved in processing Iranian crude, explicitly including Hengli Petrochemical. This is a direct political signal that Beijing will shield its refining sector from Washington’s unilateral measures related to Iranian oil. It goes beyond quiet non‑compliance by turning it into formal policy guidance, raising the stakes for enforcement and retaliation.

2) Supply/demand impact:
Iran is already exporting an estimated 1.5–2.0 mb/d, with China absorbing the majority via ‘teapot’ refiners and larger complexes like Hengli. US sanctions on specific refiners were designed to choke off part of this flow by making banks, insurers, and shipowners wary. Beijing’s explicit non‑compliance guidance reduces the deterrent effect of sanctions and makes it more likely that current Iranian export volumes are sustained or even rise by 0.2–0.4 mb/d over the next 3–6 months as refiners feel politically backed. On the margin, this is a bearish supply-side shock for crude balances, partially offsetting earlier supply risks from the Gulf and OPEC+ uncertainty.

3) Affected assets and direction:
– Brent and WTI: Bearish near-term (extra Iranian supply more secure), though partially cushioned by higher geopolitical risk premium from open US–China defiance.
– Dubai/Oman and Middle East sour grades: Under relative pressure vs light sweet as incremental Iranian barrels compete in Asia; ESPO and other Russian grades could also see some displacement.
– Chinese refining equities and crack spreads: Potentially supportive as feedstock access is politically protected; however, external financing and insurance risks rise.
– Shipping (dirty tanker, particularly VLCCs on ME–China and Iran–China routes): Supportive, as higher Iranian exports require more grey/older tonnage and complex routing.
– USD/CNH and broader EM FX: Mildly negative risk sentiment due to intensifying US–China sanctions confrontation, but impact likely modest vs core oil move.

4) Historical precedent:
Similar US–China clashes over Iran sanctions occurred 2012–2015 and again post-2018 JCPOA exit, but those involved more tacit Chinese workarounds. A formal instruction not to comply is a more overt challenge and raises odds of secondary sanctions on Chinese institutions.

5) Duration:
The supply impact is medium‑term (quarters, not weeks) as it underpins a structurally higher Iranian export base as long as US enforcement cannot effectively penetrate Chinese entities. The geopolitical risk premium component is also structural, reinforcing a trend toward de‑dollarization and parallel trade channels in energy.
