Diesel is being drawn out of floating storage in northwest Europe, where it has been accumulating during the demand lull of the Covid-19 crisis, adding to a surplus that is already weighing on regional prices.
In the last three weeks, Total and trading firm Glencore have booked six tankers between them to load a total of 180,000t of low-sulphur diesel ship-to-ship offshore Southwold in eastern England. Four of those tankers were due to load between 28 May and 3 June, and the other two are expected to load today.
The diesel is coming out of floating storage, according to market participants. There are currently two Long Range 2 (LR2) tankers, one very large crude carrier (VLCC) and one Medium Range (MR) tanker floating offshore Southwold, carrying more than 500,000t of diesel or gasoil between them, according to oil analytics firm Vortexa. Some of this product was loaded in the Mideast Gulf as long ago as late April.
The volumes coming out of storage are maintaining pressure on diesel margins to crude. Northwest European diesel cargo premiums to the North Sea Dated crude benchmark have averaged $4.47/bl in June so far, down from $6.26/bl across May as a whole and $15.06/bl in April.
The large amount of diesel being held in floating storage in the region partly explains a sharp fall in scheduled diesel loadings at the key Russian Baltic Sea port of Primorsk this month compared with May. Primorsk diesel shipments typically discharge in northwest Europe. Only 1.17mn t is scheduled to load in June, down from 1.42mn t last month.
Glencore has been selling a lot of diesel in northwest European this month. The company has sold 10ppm sulphur diesel barges at the Amsterdam-Rotterdam-Antwerp (ARA) hub on most of the trading days of June so far and has offered diesel cargoes for delivery to Amsterdam or Le Havre on every trading day.
One factor behind the drawdown of diesel from floating storage in northwest Europe is the considerable softening of the contango structure in diesel derivative markets since the end of April. A persistent contango — where contracts for later delivery trade at a premium to those for earlier delivery — has created a strong incentive to store product during the Covid-19 crisis. But it has narrowed this month. The second-month Ice gasoil contract has averaged a $9.59/t premium to the front-month contract in June so far, down from $14.33/t in May and a peak of $26/t on 28 April.
Companies appear to be drawing their floating stocks in preference to those onshore. Land-based independent gasoil storage in the ARA area is actually continuing to build, albeit slowly. ARA gasoil inventories swelled by 5.5pc to 2.76mn t in the week to 3 June, which was the highest level since October 2019, according to consultancy Insights Global.
