Global base oils margins outlook: Week of 20 October

·         Global base oils margins rise in response to increasingly lower crude oil prices.

·         Mostly-steady outright prices magnify impact of lower crude oil prices.

·         Firmer margins and steady outright prices point to stronger-than-usual fundamentals for the time of year.

·         Firmer margins incentivize refiners to maintain or raise output.

·         Such a move would increase importance of demand holding at levels that are able to absorb steady or higher supply.

·         Any signs of demand struggling to keep pace with steady or higher supply could trigger rise in surplus volumes.  

·         FOB Asia Group II base oils price-premium to Singapore gasoil rebounds, especially for light grades.

·         Group II base oils price-premium rebounds mostly because of lower crude oil prices.

·         Any signs of base oils price-premiums holding onto recent gains would point to firmer supply-demand fundamentals, incentivizing refiners to maintain higher output.

·         Price-differentials pointing to firmer supply-demand fundamentals would coincide with time of year when demand typically begins to wane and supply shows signs of rising.

·         China’s domestic Group II N150 price-premium to Shandong diesel prices rebounds to highest in five months.

·         Firm, then rebounding N150 price-premium contrasts with sliding price-differentials the same time a year earlier.

·         Group II N150 price-premium to diesel rises even with higher base oils output in China in Aug-Sept 2025 and seasonal slowdown in demand in Q4 2025.

·         Rising price-premium suggests supply-demand fundamentals are stronger than usual for time of year.

·         CFR India Group II N70 price-premium rebounds to highest since May 2025.

·         Supply fundamentals in May 2025 were tight because of widespread round of plant-maintenance throughout Asia.

·         Those tight fundamentals contrast with improving supply in Q3 2025 and lighter round of plant-maintenance work in Q4 2025.

·         High CFR India N70 price-premium and improving supply suggests demand is key factor supporting higher price-differentials.

·         Any signs of steady rather than strong demand fundamentals could erode key support for more elevated N70 price-premium.

·         Concern about mismatch between supply-demand fundamentals and high N70 price-premium could incentivize buyers to hold back, further squeezing key support from demand fundamentals.

·         Europe’s domestic Group I heavy-neutrals price-premium to fuel oil stays weak, while Group II heavy-neutrals premium stays firm.

·         Weak domestic Group I SN 500 price-premium points to weaker heavy-grade fundamentals, incentivizes refiners to consider adjusting output.

·         Weak domestic SN 500 price-premium contrasts with firm Group II domestic N500/600 price-premium to fuel oil.

·         Diverging price trends suggest weakness in heavy-grade fundamentals reflects Group I supplies rather than all base oils grades.

·         Weak domestic SN 500 price-premium contrasts with still-firm SN 500 export-price premium to fuel oil.

·         Diverging price-trends add to complication of determining relative strength of Group I heavy neutrals and any moves by refiners to respond to those price signals.

·         US Group II light-grade export price-premium to vacuum gasoil (VGO) rises to highest in more than three months.

·         Domestic Group II light-grade price premium to VGO also rises, but less strongly.

·         Rangebound domestic light-grade price-premium and firmer export price-premium incentivize refiners to maintain or raise base oils output.

·         Export light-grade price-premium rises at time of year when it typically falls in response to rising surplus supply.

·         Firmer export price-premium, especially relative to domestic price-differentials, points to relative lack of any such pressure from surplus supply.
