Tanker rates surge in Hormuz as Iran and US block traffic

A shipowner counting hulls through Hormuz last week would have found 73, down from 91 the week before, as Iran targets users of the strait and Washington blockades Iranian ports. Lloyd's List Intelligence counted them on August 19. The rate for hiring one of the few ships still willing to go tells a different story.

Earnings on TD3C, the benchmark voyage from the Middle East Gulf to Ningbo, have pushed above $520,000 a day, the strongest number in shipping. The same August 19 Lloyd's List Intelligence data put them there. A route with almost no traffic should not be the most expensive place on earth to hire a ship. It is, because the traffic you can count and the cargoes that actually move have separated, and the separation is where the money, and the risk, now live.

Tehran wants a hand it can play against Washington and treats every hull in the strait as a hostage to the negotiation. This week a seafarer died when a bulker was struck and an Emirati-linked tanker was reported seized near Qeshm Island (Lloyd's List Intelligence, Aug 19). Washington is running a blockade of Iranian ports instead. US Central Command reports 64 merchant vessels redirected, three disabled and two boarded in the same August 19 tally.

The owners caught between them have done the arithmetic: withdraw from Hormuz and let someone else take the risk. Charterers pay whatever the few willing owners ask — the state oil companies of Asia and the Gulf who still need barrels moved.

But the headline rate hides how the trade really works now. Crude is flowing through a ship-to-ship relay in Oman's waters: a tanker loads at an Iraqi or Gulf terminal, slips past or around danger, and transfers its cargo to a long-haul vessel waiting off Fujairah or Oman before heading back. ADNOC, Sinokor and Kuwait Oil Company are among the players running this shuttle playbook, according to GCC Freight on August 14. The physical trade survives while the assessed market thins out.

Freight indices like TD3C are built from reported fixture nominations by mainstream charterers. When the biggest movers stop fixing publicly and start moving cargo through their own controlled tonnage and quiet deals, the index stops describing the market and starts describing its memory.

The relay off Fujairah

The trigger for this week's squeeze was the collapse of the memorandum of understanding that had briefly organized traffic through the strait. Non-Iranian-linked traffic had actually recovered after the MoU ended — 68 transits in late July, 60 the following week, against a weekly average of 37 in the months before the MoU — but preliminary figures show it falling again, to 43, in the week of August 10. Lloyd's List Intelligence published those counts on August 19.

Underneath the trigger sits the slow pressure of insurance. War-risk cover on Gulf voyages now costs roughly 3 percent of a vessel's value against about 0.25 percent before the conflict, which Jefferies puts near $7.5 million of premium on a $250 million tanker, up from around $625,000 (Reuters, cited by Logistics Middle East, Aug 2026). At that price, every voyage is a bet the ship comes back, and owners demand either enormous freight or national patronage before they try.

Since the conflict began, 30 tankers and gas carriers from the shadow fleet — vessels that carried Iranian or Russian sanctioned oil but are not themselves sanctioned — have lifted fully compliant cargoes, including five VLCCs, and at least four very large gas carriers with Iranian LPG histories loaded in the UAE and Qatar in recent weeks. Lloyd's List Intelligence counted them on August 19.

Before the war, those hulls stayed segregated. Now a charterer desperate for tonnage takes them without asking questions, and OFAC scrutiny follows the cargo, not the handshake. The premium the compliant market pays is quietly subsidizing the rehabilitation of the very fleet sanctions built.

The owners still willing to transit profit first — their day rates say everything about scarcity. Second come the national oil companies buying their way out of dependence on third-party tonnage. ADNOC Logistics & Services recently disclosed acquisitions of six VLCCs and five VLGCs worth a combined $1.3 billion, and recent secondhand supertanker purchases have cleared well above conventional valuations, Lloyd's List Intelligence reported on August 19. Access to transportation has become a strategic asset, and Abu Dhabi is paying a premium to own it rather than rent it.

Meanwhile the container side simply absorbs the loss. DP World is spending around $100 million a month keeping Jebel Ali ready for reopening while the terminal handles roughly 10 percent of normal volume, rerouting cargo through Fujairah and a land bridge to Jeddah, Lloyd's List Intelligence reported on August 19. Hapag-Lloyd ate roughly $600 million of extra costs in the second quarter from rerouting, fuel and insurance, according to gCaptain as carried by GCC Freight on August 13.

The reflagging took years

The Tanker War of the 1980s offers one bounded model. Iranian attacks in the same waters pushed Kuwait to reflag its entire tanker fleet under the American flag and the US Navy escorted convoys through Hormuz — Operation Earnest Will. Convoys did keep the oil moving, so state power can force a chokepoint open.

But the reflagging took years to organize, the strikes continued anyway — a missile hit the reflagged Sea Isle City — and the war ended only when Iran's economy cracked, not when the escorts succeeded. There is no superpower offering escorts to everyone this time, only a partial American corridor whose claimed recovery Washington says restores up to half of pre-war exports, a figure tanker operators and vessel-tracking data challenge, Lloyd's List reported on August 21.

The counter-case has its own record. In 2019, after mines and drones struck tankers near Fujairah, war-risk premiums spiked and freight jumped, then both faded within weeks once nothing worse happened. Markets like this one have repeatedly cried wolf. If diplomacy revives — Iranian foreign minister Abbas Araghchi said talks with Oman had come close to an understanding on shipping lanes even as Tehran tied reopening to broader American concessions, NewsAnalysis.

net reported in August 2026 — the bifurcation could unwind quickly, and today's record rates would look like the top of a panic.

Anyone reading $520,000-a-day earnings as a new normal is making that bet whether they admit it or not.

Asian refiners pay more for every Gulf barrel, and Murban crude trading above $103 against Brent near $94 tells you how wide the Gulf discount-to-premium flip has gone, OilPrice.com showed on August 22. The assessed indices lose what remains of their authority, because the marginal barrel moves on private terms — national fleets, shadow hulls, ship-to-ship transfers — and a trader pricing the world off TD3C is reading yesterday's market. Capital keeps flowing to whoever owns tonnage outright, hard-wiring a two-tier shipping system where sanctioned-adjacent hulls and state-controlled fleets do the risky work while Western-flagged owners wait outside. That tiering outlives the war.

What confirms the gap. Watch Lloyd's List Intelligence transit counts and the Baltic Exchange assessments widen further, transits falling while quoted rates hold or climb. Watch for more secondhand tanker sales above valuation to state-backed buyers. What breaks it. A verified diplomatic settlement followed by war-risk quotes collapsing within days and dark-fleet hulls retreating from compliant trades, which would mean the bifurcation was panic pricing rather than a new architecture.

The crew and the terminal

The consequence lands on the crews and the terminals. A seafarer died this week on a bulk carrier nobody has claimed (Lloyd's List Intelligence, Aug 19), and the man who loaded his ship did so under an insurance policy priced like a wager against his return. The index will print a number tomorrow morning.

Whether that number describes where the world's oil actually travels is now a question each reader has to decide for themselves — and the answer determines who pays for the next hull that gets hit.
