· US supply surplus lingers into Q2 2023 even after producers clear record volume of supplies through export market in late Q1 2023.
· Ongoing flow of arbitrage shipments from US highlights need to remove lingering surplus.
· Ongoing surplus reduces producers’ leverage to target higher prices.
· Ongoing surplus, combined with high base oils prices relative to diesel, instead raise blenders’ expectations of further fall in outright prices.

· Argentina may need to rely more on domestic base oils production or US supplies over coming months amid tighter surplus availability in Europe and less attractive arbitrage for Asia-Pacific supplies.
· Argentina’s March base oils imports jumped on back of wave of arbitrage shipments from those markets and from Mideast Gulf, balancing out fall in domestic output.
· Fall in Americas Q1 supply mostly reflected planned factors such as plant maintenance work.
· Periods of unexpected drop in supply tend to have larger market impact because buyers and sellers have less time to prepare accordingly.
· Europe’s base oils supply likely to stay more balanced in Q2 after refiners cleared surplus in Q1.
· Steady regional demand in Q2 likely to limit any significant rise in surplus supply.
· Drop in competition from Russian supplies for markets like West Africa provide European refiners with convenient outlet for surplus volumes.
· Removal of Russian supplies from European market provide refiners with additional regional demand.
· US exports to Europe in March and Q1 2023 hold steady rather than surge, curbing any build-up of surplus supplies in European market.
