In late July 2026 the Iranian tanker *Humanity* entered Malaysia’s Eastern Outer Port Limits, switched off its AIS and carried out a ship‑to‑ship transfer of Iranian crude bound for China. The area has long been a hub for sanctioned Iranian, Russian and Venezuelan oil, and the activity persisted throughout the five‑month U.S.–Israel conflict despite a U.S. naval blockade that began in mid‑April and was briefly lifted in early July.

By early August, the blockade’s impact deepened: loading at Iran’s main export terminal on Kharg Island was halted, leaving no tankers loaded for over a week. Dozens of Iranian vessels idled off Malaysia, and weak Chinese demand left the cargo without buyers, bringing Iran’s oil export flow to a near‑standstill.

Satellite imagery on 7 August showed the three berths at Kharg Island still empty for more than a week, with only 16 tankers anchored—the lowest count since early July. Iranian crude tankers continued to idle in the Gulf and near Malaysia, while weak Chinese demand caused stockpiles to build offshore. Analysts warned the export halt could force Tehran to curb production to avoid storage overflow, though officials said the sanctions were unlikely to prompt immediate concessions. Overall, the period shows a shift from covert transfer operations persisting despite the blockade to a broader suspension of Iran’s oil export capacity as U.S. pressure intensified and market demand faltered.
