**Summary**: China’s Commerce Ministry has reportedly instructed domestic firms not to comply with US sanctions targeting refiners linked to the Iranian oil trade, including Hengli Petrochemical. This signals Beijing’s political backing for continued Iranian crude inflows, undermining US enforcement and potentially increasing effective Iranian export capacity, modestly bearish for crude benchmarks and bullish for freight and sanctions-risk premia.

## Detail

1) What happened:
China’s Ministry of Commerce has instructed domestic companies not to comply with US sanctions on refiners involved in the Iranian oil trade, explicitly including Hengli Petrochemical. This amounts to a formal political signal that Beijing will backstop key refiners against US secondary sanctions risk, shifting the perceived cost-benefit for Chinese buyers of Iranian crude.

2) Supply/demand impact:
Iran is already exporting an estimated 1.4–1.8 mb/d, with China as the dominant buyer via ‘teapot’ and some larger refiners under opaque arrangements. Official Chinese non-compliance guidance reduces the deterrent effect of new or existing US sanctions, raising the probability that Iranian flows are maintained or even increase by several hundred kb/d over the coming quarters. In the near term (days–weeks), the key effect is on market expectations: traders will discount the likelihood that US measures can materially clamp down on Iranian exports. That exerts modest downward pressure on flat price and reduces upside tail risk from a sanctions squeeze.

3) Affected assets and directional bias:
– Brent/WTI: Slightly bearish for front and especially deferred crude contracts, as effective OPEC+ spare capacity (via Iran) is perceived as more monetizable despite current geopolitical tensions.
– Dubai/Middle East crude benchmarks: Bearish vs. Atlantic grades, as China’s comfort with Iranian barrels increases competition among sour suppliers.
– Freight (Aframax/Suezmax, AG–China and Iran–China routes): Constructive, as steady or higher sanctioned flows sustain tonne-miles and shadow-fleet utilization.
– US refiners and compliant Asian refiners: Mildly negative on competitive pressure from discounted Iranian barrels into China and potentially other Asian markets via re-exports/blends.

4) Historical precedent:
The move echoes past periods when China and the EU limited adherence to US secondary sanctions on Iran (2012–2015, 2018–2020), during which Iranian exports remained higher than US policymakers targeted and crude prices reacted more to physical disruptions than legal announcements. The novelty here is the explicit instruction not to comply, which hardens the stance and reduces uncertainty for Chinese buyers.

5) Duration of impact:
This is structurally important rather than transient. It signals a more durable geopolitical split over sanctions enforcement and suggests that any future US Iran-tightening measures will have less bite in physical markets than headline risk implies. The pricing impact today is moderate but alters the risk balance on medium-term Iranian supply.
