Iran oil sanctions: 35 more targets

Treasury on Apr. 28, 2026 designated 35 entities and individuals in Iran’s shadow-banking architecture tied to illicit oil sales, widening the squeeze beyond tankers into payment rails home.treasury.gov. That follows the Apr. 24, 2026 move against Hengli Petrochemical, which Treasury called one of Iran’s largest customers, plus about 40 shipping firms and vessels in the shadow fleethome.treasury.gov ofac.treasury.gov). The market read-through is straightforward: this is a logistics-plus-settlement hit, not just another tanker-name add, because Treasury says the network moves the equivalent of tens of billions of dollars and helps the IRGC get paid. The bull case for crude is that coordinated pressure on buyers, shippers, and payment channels makes rerouting harder; the bear case is the familiar one, where flows relabel, reflag, and keep moving. Treasury also framed this as cumulative pressure, noting that since Feb. 2025 OFAC has sanctioned about 1,000 Iran-related persons, vessels, and aircraft home.treasury.gov. What changes the tape is follow-through that strands barrels rather than reroutes them.
