The Smyrni, a tanker operated by Greek shipowner George Prokopiou's Dynacom, transited the strait of Hormuz on Friday with its automatic identification system transponder switched off and armed guards on deck 1. It is the company's fifth vessel to pass through the strait since the IRGC declared on 10 March that "not a litre of oil" would transit . No other major shipping company has followed.
Dynacom is chartering vessels for the run at $440,000 per day — roughly four times pre-war rates. The premium reflects the hazard. The International Maritime Organisation's cumulative tally since 28 February counts 19 vessels attacked and at least 7 seafarers killed . Six commercial vessels were struck within a 14-hour window last week across 200 kilometres of water from Hormuz to Iraq's Basra terminal . US Navy officials have described the strait as an Iranian "kill box" with pre-registered fire zones . Prokopiou is sailing into that.
The economics explain why. At $440,000 per day, the charter sounds extreme — until measured against the cargo. Brent closed Friday at $103.14 . A single VLCC carrying 2 million barrels is worth over $200 million at that price. The daily charter is a fraction of a percent of the cargo value. Greek shipowners have run contested waterways before: during the Iran-Iraq tanker war of 1984–88, Greek-flagged vessels continued operating in The Persian Gulf when others withdrew, and owners who stayed earned outsized returns. Prokopiou is following that playbook — pricing political risk as a commercial opportunity rather than a deterrent.
But Dynacom's transits are an anomaly, not a reopening. 11.7 million barrels of Iranian crude have flowed through Hormuz since 28 February, all bound for China, tracked by TankerTrackers.com co-founder Samir Madani via satellite . Chinese-operated vessels broadcast their nationality and receive de facto IRGC protection . The blockade has a two-tier structure: open for Chinese-linked commerce, functionally closed for everyone else. Dynacom's Greek-flagged tankers occupy a third category — vessels betting that the IRGC will not risk an escalation with a NATO-member state's commercial fleet while its primary adversary remains the United States Navy. That bet has held five times. Daily transits remain in single digits against a historical average of 138 . the strait is not open. One company is running the odds.
