Domestic Group II base oil margins over feedstocks and competing fuels extended their decline for a seventh consecutive week on elevated feedstocks and firmer competitive fuel prices.
The Argus domestic spot US Group II N100 premium to four-week average low-sulphur vacuum gasoil (VGO) dropped to $1.28/USG for the week ended 27 June, from $1.30/USG the week prior. Margins remained below year-earlier totals of $1.36/USG.
The Argus domestic spot US Group II N100 premium to four-week average US Gulf coast diesel was $1.00/USG, down from $1.06/USG the week prior. Margins also remained below year-earlier totals of $1.13/USG.
US Group II base oil spot prices were flat because muted demand outweighed fewer spot volumes.
Group II light-grade supplies are limited, and domestic re-refiners are still working to catch up on orders following a heavy turnaround season.
Mid-grade supplies are more balanced because of recent exports to South America and Asia. Heavy grade supplies are not as lean as light grade material, but some buyers are noticing more limited availability. Other buyers are not having issues obtaining spot volumes.
Four-week average vacuum gasoil (VGO) rose for a seventh consecutive week because of persistent tightness. Margins for fluid catalytic crackers (FCC) also increased. Four-week average diesel prices have steadily increased since 30 May.
The low-sulphur VGO premium to four-week WTI crude narrowed further to $12.79/bl from $13.13/bl the week prior.
