How High-Flash Chemistry is Entering the 380 Bull Run
The paper market thinks residual fuel oil is a homogeneous clearing pool.
The reality on the water is that genuine, deliverable 380 CST / 3.5% HSFO is in structural deficit.
Capturing this bull run requires molecular craft.
Vitol pioneered trading heavy Cuban crude — Varadero and Pino Colado — because the geology naturally solved a regulatory roadblock: it contained virtually no volatile light fractions.
With a closed-cup flashpoint well clear of the SOLAS 60°C minimum, Vitol bypassed traditional refining slates, blending raw crude directly into residual bunker and burner pools.
When Cuban volumes tightened, the strategy migrated to China.
Vitol shipped heavy sour feeds into Shandong, contracting independent “teapot” refiners to strip out volatile naphtha overheads.
Under bonded tolling arrangements, Vitol took redelivery of the stripped, high-flash Atmospheric Tower Bottoms (ATB) to blend into deliverable bunker fuel across Southeast Asia.
The Shandong model carried quota friction, regulatory exposure and double-handling freight costs.
Vitol eliminated those bottlenecks by constructing its own ~30,000 b/d simple distillation unit directly inside its ATB terminal at Tanjung Bin, right across the Johor Strait from Singapore.
The trade has now pivoted from Havana to Vancouver:
Suncor is loading a 90,000 MT Western Canadian Select (WCS) cargo off TMX at Vancouver 15–17 September, using a Vitol relet, Cape Antibes.
With two days loading, the stem sails 17 September and hits Tanjung Bin on 11 October.
WCS dilbit arrives carrying 25% to 30% light condensate / naphtha diluent — flashpoint <0°C, totally barred under SOLAS.
At Tanjung Bin, the topping tower flashes off ~25,000 MT of light ends into regional gasoline and petchem pools.
Vitol is left with ~65,000 MT of uncracked, high-density, high-sulphur residual bottoms, carrying an on-spec flashpoint well above 70°C.
65,000 MT backs three full 20,000 MT physical delivery clips in the Platts MOC window.
Blended at the terminal headers with cutter stock to balance viscosity and density, it yields 75,000 to 80,000 MT of finished on-spec 380 CST, handing Vitol physical delivery coverage for four distinct MOC delivery obligations.

Over the 1–2 September prints, October 380 outright OI expanded +191 lots, from 5,040 to 5,231, on heavy back-to-back block prints of 1,553 lots and 1,459 lots.
October Crack (380CRK) added +175 lots, from 1,266 to 1,441.
While October compounded aggressive institutional length, November OI shed -24 lots.
This is not a passive strip roll; macro capital is weaponising the prompt October / November spread.
October Visco widened to -447, a -10 $/MT delta, demonstrating that cutter economics are tightening fast.
Blenders cannot easily buy their way out of off-spec heavy barrels without paying steep premiums for sweet distillate components.
While Asia captures the headline focus due to Singapore MOC volatility and block volume prints, Northwest Europe is significantly tighter than the Far East.
The market there is drowning in high-metals residual fuel oil — vanadium 450–700+ ppm — arriving from Colombia, Mexico and Venezuela.
These barrels are phantom supply: they cannot legally clear bunker manifolds without failing ISO 8217 RMG specifications.
Secondary upgrading units in places like Bilbao and Rotterdam / Antwerp are completely fine running these heavy Latin American barrels.
However, for merchant bunker blenders, these high-metal barrels are completely out.
Coker-bound 3.5% vs. bunker-suitable 3.5% are two very different pool contribution stories.
The Red Sea region is cooling and will soon ease furnace burn, which should free up SOMO SRFO from Syria for Med and NWE blenders.
An Iraqi player just paid USD 200 million for a second-hand VLCC.
For context, new ones are getting contracted at USD 130 million at the moment.
That speaks to how Iraqi tank tops are in dire straits.
