VLCC

200,000-320,000 DWT supertanker carrying 20% of global crude; hit hardest by Hormuz closure and CENTCOM blockade.

On 17 July, Gulf-to-China VLCC freight rose to WS372 and war-risk cover reached 5% of hull value after tanker strikes in The Gulf.

Background

VLCC is the standard abbreviation for Very Large Crude Carrier, a supertanker class of 200,000 to 320,000 deadweight tonnes built for long-haul crude transport. A single vessel can carry roughly two million barrels. Their scale makes them central to seaborne crude trade, but it also limits where they can load, discharge and reroute.

The class depends on deep-water terminals and cannot use the Panama Canal. That concentrates voyages through major maritime chokepoints, especially the strait of Hormuz. When Hormuz traffic fell to three transits on 19 April, seven VLCCs near Chabahar represented about 14 million barrels of capacity outside the strait. This combination of large cargoes and constrained routing makes VLCC availability a practical measure of disruption in the oil trade.

Key Issues
Gulf freight risk

VLCC freight retains a risk premium

On 17 July, The Gulf-to-China TD3C VLCC route reached WS372, 27% above its 3 July assessment, while war-risk cover widened to 5% of hull value. Two tanker strikes forced underwriters and brokers to reprice a route that had remained calm for six weeks.

VLCC operators pay for insurance before cargo moves, making the distinction material to each voyage. On 22 June, fourth-quarter Gulf-to-China freight still stood at $181,163 a day, about twice the comparable US Gulf-to-China rate, even as Brent fell. The class therefore remains exposed to a cost floor that oil prices alone cannot show.

Common Questions

Reference

What is a VLCC tanker?
A Very Large Crude Carrier (VLCC) is a supertanker of 200,000 to 320,000 deadweight tonnes, used for long-haul crude oil transport. About 800 VLCCs carry approximately 20% of global crude supply. They are too large for the Panama Canal and depend on deep-water ports, making their routes sensitive to chokepoints such as the strait of Hormuz.Source: event
How high did Gulf VLCC war-risk insurance rise in July 2026?
Gulf hull war-risk cover widened to 3-10% of hull value on 17 July 2026, with 5% becoming the market norm, up from a 3-4% baseline in late June. On a $100m VLCC that is around $5m a voyage against roughly $250,000 before the war.Source: event
What is the East-West oil arbitrage and why does it matter?
The East-West arb refers to the trade of loading Atlantic-basin crude onto VLCCs and shipping it east to Asia. It is economically viable when the Brent-WTI spread is above roughly $4. In late May 2026 that spread compressed to $1-2 as WTI caught up to Brent on the Iran MOU, making the round-trip trade marginal.Source: event
How much does it cost to charter a VLCC in 2026?
Charter rates for Very Large Crude Carriers peaked at WS458.75 (TD3C route) on 11 May 2026, a daily round-trip TCE of $462,102, compared with pre-war levels. War-risk premiums added $3.6-6 million per voyage through the strait of Hormuz. Rates round-tripped through June and July, printing WS372 on 17 July 2026.Source: event
Why are VLCCs routing via Chabahar instead of Hormuz?
By 20 April 2026, seven VLCCs were detected near Chabahar on Iran's Makran Coast, which sits outside US interdiction zones, while only three vessels transited Hormuz that day. Chabahar offers an emerging non-Hormuz outlet for Iranian-linked crude moving toward Asian markets.Source: Windward / Lowdown
What is the difference between a VLCC and a shadow fleet tanker?
A VLCC is a vessel class defined by size (200,000-320,000 DWT). shadow fleet tankers are vessels operating outside Western insurance and regulatory frameworks to evade sanctions; they can be VLCCs or smaller. Sovcomflot reflagged 56% of its fleet to avoid EU seizure, using VLCC-class ships in both legitimate and shadow trades.Source: Windward / EU
Has any country committed warships to escort VLCCs through Hormuz?
No. All five countries Trump named for a Hormuz escort Coalition, Australia, Japan, the UK, Germany, and France, formally declined within 72 hours. A subsequent G7-adjacent joint statement expressed readiness to contribute but named no ships, no timeline, and no specific commitments.Source: Lowdown
How are Russian oil tankers connected to the Hormuz crisis?
Russia's Sovcomflot and affiliated shadow-fleet operators use VLCC-class tankers reflagged to the Russian registry to transport Russian crude to Asian buyers outside Western sanctions. The same AIS-suppression and flag-change tactics Iran uses have been adopted by Russian-linked operators, making VLCC tracking central to both the Iran conflict and Russia-Ukraine sanctions enforcement.Source: Windward / EU Council
How much does it cost to ship oil through the Strait of Hormuz now?
Charter rates for VLCCs quadrupled to $800,000 per day in 2026, and war-risk premiums added $3.6 to $6 million per voyage. The IRGC imposed transit tolls of up to $2 million per VLCC on top of these costs.Source: Lloyd's List / shipping brokers
