· Diesel premium to crude oil extends rise to highest since Q1 2023, to levels well above pre-2022 levels.
· Strong diesel premium to crude, and sliding base oils premium to diesel, incentivizes refiners to cut base oils output.
· Light-grade base oils supply could tighten more as refiners redirect supplies back into diesel pool.
· Any moves to boost diesel or cut base oils output would cushion impact of pause in scheduled plant maintenance work in US over coming weeks.
· Weak base oils margins could incentivize Europe refiners to extend maintenance work affecting several plants.
· European supply could get boost from signs of pick-up in flows from Turkey.
· US’ May base oils supply extends rebound to seven-month high following completion of plant maintenance work.
· Rise in supply in May increases importance of sustaining open arbitrage and large exports to overseas markets to counter weak domestic demand.
· US arbitrage shipments to markets like Africa and India continue through June and July.
· Steady arbitrage shipments point to ongoing surplus, and rapid removal of some of the surplus.
· Rise in May supply coincides with firmer base oils margins in Q2 2023; slump in margins in Q3 2023 cut incentive to maintain high output.
· Argentina continues to rely mostly on imports to cover base oils requirements in Q2 2023.
· Almost all its imports originate from US in Q2 2023, contrasting with lower share in Q1 2023.
· Trend reflects closed arbitrage from Europe and Asia and competitive US prices in Q2 2023.
· Trend likely to continue in Q3 2023, with US prices still competitive, Europe prices uncompetitive and Asia prices less competitive than last year.
· Netherlands’ lower base oils supply in May falls below typical levels, partially balancing out surge in supplies in April.
· Still-competitive US Group II prices versus Europe prices raise prospect of larger-than-usual shipments to the region.
· Trend would keep pressure on Netherlands’ base oils supply to stay lower to avoid supply-build during seasonal slowdown in demand during Q3 2023.
· Netherlands’ May base oils supply includes unusually large volume of Group III base oils from Mideast Gulf and southeast Asia.
· Repeat of those flows would be more problematic in Q3 2023 following restart of Group III base oils unit in Spain in June 2023.
· Netherlands’ May base oils supplies include steady, even if low, volumes from China.
· Before March 2023, Netherlands had previously imported almost no base oils from China.
· Any extension or expansion of that trend would be structural change that would impact other more established supplies.
· UK’s May base oils supply rises to highest since Q4 2020, even amid weak domestic and regional lube demand.
· Rising supply includes pick-up in Group I base oils output at a time when Europe and Africa are seeking to cover for loss of supplies from Russia.
· Rising Group I base oils output taps firm regional Group I base oils prices in Q2 2023, especially relative to export prices.
· Rising Group I base oils output coincides with/cushions impact of drop in Group I output in Italy.
· Rising Group I base oils output reflects widespread repercussions of change in trade flows and production plans to cover demand.
· UK’s May base oils surplus of supply over demand rises to highest since 2018.
· Surplus likely to consist more of premium grades than Group I base oils.
· UK’s rising base oils surplus in Q2 2023 likely to be harder to clear in Q3 2023 when demand faces typical seasonal slowdown.
· Any lingering surplus could add to slowdown in demand, put more pressure on prices.
· Group III base oils exports from Spain rebound in July to four-month high.
· Wave of premium-grade shipments from Mideast Gulf and Asia cushion fall in exports from Spain during plant-maintenance in May-June.
· Shipments from Mideast Gulf and Asia will need to fall, following resumption of normal exports from Spain in July, to avoid oversupply of Group III base oils in Europe.
