· Diesel prices weaken versus crude oil to lowest in three months, stay higher than usual.
· Lower diesel margins and firmer base oils margins could incentivize refiners to maintain or raise output at a time of year when demand typically eases.
· Americas Group I base oils supply likely to stay lower because of plant maintenance work in Q4 2023.
· US Group II refiners could face more pressure to adjust run-rates if recent import-rule changes in Mexico curb flow of shipments of light-grade base oils to that market.
· Any such slowdown would cut outlets for surplus light-grade supplies at a time when domestic demand in US faces seasonal slowdown.
· Closed arbitrage to move Group II supplies to India limits further US refiners’ options unless prices adjust to make arb more feasible.
· US Group III supply shows signs of pick-up in flows from Asia and Mideast Gulf in Oct 2023.
· Europe’s Group III supplies from Mideast Gulf show signs of rising in Oct 2023 after slowing in Sep 2023.
· Europe’s imports of Group III base oils from Mideast Gulf rise in three months to August, lag slightly the volume of supplies bound for US.
· US imports from Mideast Gulf previously far exceeded volume of supplies bound for Europe.
· Trend coincides with weaker US demand for Group III base oils, compounds surplus Group III base oils supplies in Europe.
· Any extension of that trend would likely maintain pressure on Europe’s Group III market.
· Europe’s Group III base oils supplies from Mideast Gulf show signs of slowing in September before rising again in October.
· South Korea’s September base oil exports to Europe rise to five-month high.
· Rise in Group III shipments would coincide with signs of pick-up in supplies from Mideast Gulf reaching Europe in October.
· Rise in shipments coincides with signs of slowdown in shipments from Spain in October.
· Europe’s Group II supplies from US likely fall in Oct 2023 vs Sep 2023 following slowdown in shipments in recent weeks.
· Lack of surplus Group I supplies in Europe in recent months countered impact of closed arbitrage and weak demand in markets like North Africa and Turkey.
· Any rise in surplus supplies at year-end would face challenge of prices adjusting to levels that make the arbitrage feasible, and lining up outlets where demand is sufficient to absorb the supplies.
· Slowdown in global base oil exports to Egypt throughout most of this year highlights that challenge.
· Southeast Asia shows signs of becoming more regular outlet for supplies from Europe, after plant closure in Japan tightens structural supply of Group I in the region.
· Spain’s fall in Group I base oils output and run-rates continues through August, contrasts with steadier diesel run-rates.
· Trend suggests refiners focusing more on boosting diesel output rather than base oils.
· Global base oils exports to Mideast Gulf rise to four-month high in August, extending surge in shipments to the region.
· Supplies from Asia account for almost 60pc of shipments to Mideast Gulf in first eight months of 2023, up from around 40pc during same period last year.
· Trend reflects surge in Mideast Gulf base oils demand, and Asia refiners benefiting the most from that rise in demand.
· Trend highlights change in global trade flows in face of tighter European supply and rising surplus volumes in Asia and US.
