Key takeaway

Unclaimed strikes cannot be insured on a schedule, keeping the Hormuz hull premium pinned near 5%.

Two tankers operated by Dynacom Tankers, a Greek shipping company, were hit by unclaimed projectiles inside the Strait of Hormuz on 19 and 20 July 1. The Malta-flagged product carrier Kavomaleas took two projectiles about 8 nautical miles north of Kumzar, Oman, on 19 July, and an engine-room fire forced the crew to abandon ship. The Liberian-flagged supertanker Acheloos was struck in its steering-gear compartment at roughly the same spot on 20 July.

No party has claimed either strike, which puts them in a different category from the state-attributed infrastructure attacks the Gulf war has produced so far . A tanker hit by an anonymous projectile cannot be insured against on any predictable schedule, and that uncertainty, more than any single loss, keeps the Hormuz hull premium pinned near 5% of hull value.

Deep Analysis

In plain English

Two tankers operated by the Greek shipping company Dynacom Tankers, the Kavomaleas and the Acheloos, were hit by projectiles inside the Strait of Hormuz on 19 and 20 July. Nobody has claimed responsibility for either strike. The Kavomaleas, flying the Malta flag, took two hits near the Omani town of Kumzar and its crew abandoned ship. The Acheloos, a Liberian-flagged supertanker, was struck in the compartment that houses its steering equipment. Unclaimed strikes matter because they leave shipowners and insurers unable to assess who is responsible or what triggers further attacks, making it harder to price risk or plan safe routes through one of the world's most important oil chokepoints.

Deep Analysis
Root Causes

Strikes inside the Strait of Hormuz carry different escalation risk than strikes at Bab el-Mandeb because Hormuz sits directly opposite Iranian territory and Revolutionary Guard naval assets, making any claimed attack there a much sharper diplomatic and military signal than a Houthi strike hundreds of miles south. That asymmetry is the likely reason no party has claimed the Kavomaleas and Acheloos strikes even as the Houthis openly claimed the Encelia and Layla attacks.

Dynacom Tankers' exposure is structural to its fleet mix: a Greek operator running both Malta-flagged product carriers and Liberian-flagged supertankers through Hormuz has no chokepoint-free route for that trade, unlike Saudi Arabia's Yanbu bypass for Red Sea-bound cargo.

What could happen next?
  • Risk

    Unclaimed strikes inside Hormuz itself, rather than at Bab el-Mandeb, would mark a distinct escalation track that war-risk underwriters have not yet separately priced from the existing Hormuz baseline.

Different Perspectives
US money managers (CFTC-tracked)
US money managers (CFTC-tracked)
US money managers had trimmed WTI net long positioning into July's rally, doubting the Hormuz premium would hold without freight or war-risk confirmation, and the crude stock build reported for the week to 17 July gives that scepticism a fundamentals basis. The 25 July CFTC data will show whether Brent's move above $100 changed their calculus.
Asian distillate buyers (Singapore)
Asian distillate buyers (Singapore)
Singapore's distillate holders kept retaining middle-distillate barrels as the East-West arbitrage window narrowed further this week, a pattern that sharpened as Fujairah light distillates hit a record low. Cargoes are being held rather than released west into the tightening Mediterranean market.
Bulgaria
Bulgaria
Bulgaria secured the removal of Lukoil founder Vagit Alekperov and Patriarch Kirill from the 21st package, with President Rumen Radev calling a personal listing 'shooting ourselves in the foot'. Sofia is protecting its position in Lukoil's EUR 3bn compensation claim over the 2023 Neftohim Burgas nationalisation.
Russia
Russia
Russia loses the roughly $14 a barrel of legal headroom the price-cap formula would have released toward $58, even as Urals continues trading below Moscow's $59 budget floor. The shadow-fleet insurance workaround that lets sanctioned crude clear above $44 in practice remains untouched by the freeze itself.
European Union
European Union
The EU adopted its 21st sanctions package on 23 July, freezing the $44 Russia oil cap for 12 months rather than letting the formula drift it toward $58, and listed shadow-fleet support vessels for the first time. The package cleared only after three failed Coreper votes.
Marine war-risk underwriters (Lloyd's-linked syndicates)
Marine war-risk underwriters (Lloyd's-linked syndicates)
War-risk syndicates lifted southern Red Sea hull premiums 150% to about 0.75% of hull value after the 20 July blockade declaration, still a seventh of the roughly 5% Hormuz band. Underwriters reset on realised loss, not declared threat, so the 23 July Encelia and Layla strikes set up the next re-mark.
