US Group II base oil margins over feedstocks and competing fuels rose for the week ended 26 July as base oil prices were steady and feedstock and competing fuel values fell.
The Argus domestic spot US Group II N100 premium to four-week average low-sulphur vacuum gas oil (VGO) rose to $1.45/USG from $1.43/USG last week. Margins remained above year-earlier levels of $1.10/USG.
The Argus domestic spot US Group II N100 premium to four-week average US Gulf coast diesel was $1.20/USG, up from $1.18/USG a week prior. Margins remained above year-earlier levels of 67¢/USG.
US Group II spot prices were steady on higher demand and balanced to snug inventories.
Spot availability of Group II N100 remains limited as refiners direct available volumes toward hurricane stockpiles. Some refiners were incentivized by Hurricane Beryl to build stronger inventories, despite its minimal impact.
Some market participants also expect that Group II refiners continue to cut yields by producing more Group III base oils, particularly in the US Gulf coast.
Several market participants have not experienced any impact or tightness on contractual Group II volumes.
Feedstock VGO costs fell as declines in crude prices outweighed some higher demand. A fluid catalytic cracker (FCC) came back online in the US Gulf coast last week after an unplanned outage. Another FCC unit remains down, weakening demand for VGO.
Margins for low-sulphur VGO to four-week average WTI crude widened to $11.11/bl, up from $10.92/bl last week.
US Gulf coast diesel values also fell during the week, further boosting base oil margins. Premiums for base oil over diesel continue to incentivize refiners to prioritize base oil over competing fuels
