· Global base oils prices mostly hold firm versus feedstock/competing fuel prices amid further drop in crude oil prices.
· Mostly-steady outright base oils prices and lower crude prices cushion impact of strong gasoil premium to crude oil.
· Strong gasoil crack-spread incentivizes any refinery moves to trim output levels to focus more on light grades than heavy grades.
· Margins that incentivize steady or higher heavy-grade output coincides with time of year when demand typically slows.
· FOB Asia heavy-neutrals base oils prices continue to trend lower vs Singapore gasoil, while light-grade price-differentials hold in narrower range.
· Heavy-grade price margins face pressure from persistent surplus supply.
· Heavy/light-grade base oils margins continue to face pressure from firm gasoil premium to crude oil.
· Still-steep premium of Group II heavy grades over light grades incentivizes refiners to focus any output-changes on light grades rather than heavy grades.
· Any such moves would compound current supply-demand imbalance between light and heavy grades.
· Domestic China Group II N150 price-premium to Shandong diesel holds steadier.
· Steadier N150 price-premium stays slightly below highs of H1 Sept 2025.
· Steadier N150 price-premium to diesel contrasts with sharp fall in price-premium from end-Sept 2024.
· Steadier price-premium this year could point to more balanced supply-demand fundamentals despite high domestic output in Aug-Sept 2025.
· Dynamic could point to firmer demand or to impact of some domestic plant-maintenance work in early-Q4 2025, or to combination of both.
· Either way, steadier price-premium curbs incentive for refiners to trim output.
· CFR India Group II N70 price-premium to Singapore gasoil holds firm, pointing to strong demand and balanced-to-tight supply.
· N70 price-premium holds at level that makes feasible the arbitrage to move supplies from Asia to India.
· Strong gasoil premium to crude oil could still incentivize Asia refiners to focus more on diesel production instead of light-grade base oils.
· Firm N70 price-premium to gasoil/heating oil, and any sustained slowdown in US shipments to Mexico, could boost incentive to move more of those supplies to India.
· Europe Group III 4cSt (low) price-premium to fuel oil holds firm after sustained rebound since early-2025.
· Rise in Group III price-premium far outpaces firm Group II light-grade price-premium to fuel oil.
· Firm Group III price-premium points to increasingly strong fundamentals versus Group II base oils, incentivizes suppliers to boost regional output or move more shipments to Europe.
· US Group II light-grade domestic base oils prices remain in narrow range vs vacuum gasoil (VGO).
· Relative narrowness of price-range so far this year contrasts with more volatile spot and posted-price margins in 2023 and 2024.
· Stability of price margins points to more balanced supply-demand fundamentals this year compared with 2023-2024.
· Stability of price margins incentivizes refiners to maintain high output, with expectations of sufficient domestic or overseas demand to absorb the supplies.
