· US base oils supply lags demand in April 2025 for third month, cutting stocks to eight-month low.
· Persistent supply-shortfall triggers fastest drop in stocks over three-month period since September 2020, when US was in midst of Covid-related supply disruptions.

· Plant-maintenance work in Middle East and Asia in Q2 2025 coincides with signs of slowdown in shipments reaching US in May-July 2025.

· Brazil’s base oils supply stays unusually high in May 2025 for second month, reflecting that pick-up in shipments from US.
· Brazil’s base oils imports from US rise to six-month high in May 2025, even amid slump in US base oils output at start of Q2 2025.
· Wave of shipments from US, even during round of plant-maintenance work, points to Latin American markets like Brazil as priority outlets for US suppliers.
· Brazil’s infrequent shipment of large export cargo in May 2025 points to sufficient supply.
· Dynamic raises risk of mismatch between supply and demand if US exports to Brazil remain at more elevated levels.
· Argentina’s Group I base oils output stays higher than usual in May 2025 even as exports pause.
· Output could hold at more elevated levels to tap blenders’ concern about strength of domestic lube demand, boosting their incentive to procure smaller volumes more frequently from local sources.
· Output could hold at more elevated levels to take advantage of tight Group I fundamentals in overseas markets.
· Any change in either of those factors could prompt adjustment in output to avoid build-up of surplus volumes.
· Europe’s Group I base oils supply likely to extend recovery in coming weeks as plant-maintenance draws to close and demand slows.
· Demand could face further pressure after slump in supply in early-Q2 2025 incentivizes blenders to switch to other base oils grades instead.
· Some of those blenders could continue to use those other grades even after recovery in Group I supply.
· Size of recent drop in Group I supply highlights Europe’s dwindling number of Group I plants and larger impact of any drop in output from remaining plants.
· Europe’s Group I base oils supply falls to seventeen-month low in April 2025.
· Timing of fall in supply, at time of year when demand faces seasonal rise, compounds impact of tighter availability.
· Group I supply, less exports to markets outside Europe, falls even more sharply in April 2025, compounding tight regional availability.
· Drop in supply highlights Italy’s reliance on sole Group I unit in that country and regionwide impact of any change in production at the unit.
· Drop in supply, combined with uncompetitive Group I prices for export markets, provide additional incentive for overseas buyers to turn to other sources to cover their requirements.
· Europe’s Group II base oils supply likely to hold steady, extending that trend since late last year.
· Steady supply contrasts with dip in Group I base oils supply, especially at start of Q2 2025.

· Steady supply boosts Group II share of Europe’s Group I/Group II supply in Jan-April 2025.
· Any extension of steady Group II supply, combined with recovery in Group I base oils supply, could trigger pick-up in surplus volumes.

· Supplies with full set of OEM approvals could stay tighter amid pause in flows from Spain through most of June 2025.
· Shipment of cargo to northwest Europe in early-July 2025 is first in a month.

· Dip in Group III supply at start of Q2 2025 coincides with drop in Group II and especially Group I base oils supply.
· Simultaneous and steeper drop in Group I and Group III base oils supply adds to incentive for blenders to use more Group II base oils instead.
