1) Shadow fleet in the crosshairs—yet still moving

Treasury’s Aug 21 action named Hong Kong shipowners tied to ADELINE G and KONGM, detailing voyages that delivered “millions of barrels” of Iranian oil to China and even ship-to-ship transfers with a previously sanctioned vessel. State Department guidance on Jul 30 likewise warned terminal operators and port agents servicing Iran’s trade. Practically, this raises financing and insurance costs and forces the fleet deeper into opaque flags, STS choreography, and off-grid AIS behavior—but the flows have not stopped. For Tehran, sustaining these routes is central to regime survival and regional deterrence. (U.S. Department of the Treasury)

2) China’s safety valve—volumes resilient, price weaker

Despite tightening sanctions, China’s intake remains the lifeline. Kpler-based reads show August offloads around 1.68 mb/d with September upticks at Huangdao; traders report >$6/bbl discounts to ICE Brent for October arrivals—wider than March’s ~$3. The trade-off is clear: Iran swaps margin for throughput, keeping cash moving and inventories circulating, while Beijing arbitrages geopolitical risk. The dynamic underscores Tehran’s eastward economic anchoring—deeper commercial integration with a non-Western buyer that shrinks Western coercive leverage. (Reuters)

3) Crypto pipelines under sanction

On Sept 16, Washington sanctioned Iranian financiers and a web of UAE/HK affiliates for allegedly laundering >$100m in crypto tied to oil sales. The move targets an adaptation Tehran has leaned on since banking channels came under heavier scrutiny. Crypto didn’t replace banking; it supplemented it—settling arrears, skimming exchange rates, and paying vendors across front companies. Cutting these rails adds friction and delays, but Iran’s distributed “money-services” ecosystem tends to route around blocks within weeks, shifting the burden to ever-larger compliance nets in the Gulf and Asia.

4) Iraq’s energy hinge—leverage and constraint

Iran’s mid-August halt of electricity exports to Iraq (citing domestic demand) re-demonstrated Tehran’s ability to squeeze Baghdad at peak load. Separately, Reuters reports on Sept 19 that Washington nixed Iraq’s plan to import Turkmen gas via Iran, arguing it would advantage Tehran under sanctions. Together, these moves crimp a key hard-currency interface for Iran and limit Baghdad’s workarounds, even as they spotlight how intertwined the systems remain. Expect Tehran to leverage outages and payment disputes politically while nudging Baghdad toward non-Western payment channels that preserve Iranian receipts. (S&P Global)

5) Re-flagging the barrels—“Iraqi” crude that isn’t

OFAC’s Sept 2 action against an Iraq-based network allegedly rebranded Iranian oil as Iraqi origin, using mixed cargoes, falsified documents, and permissive registries. Unmasking these schemes raises counterparties’ risk and deters mainstream traders/insurers, but it also pushes sales further into gray markets where Iran already operates comfortably. Tehran will double down on barter, local-currency clearing, and smaller, harder-to-police cargoes—tightening ties with Eurasian corridors and sympathetic brokers. (Herbert Smith Freehills)
