Base oil values in the Asian FOB market have moved up again this week, though the tone across the trade remains anything but one-directional. Buyers are largely holding back in hopes that values soften, even as suppliers point to a genuinely constrained flow of material out of the Middle East amid ongoing concern tied to the US-Iran standoff. The move is broadly tracking the wider crude complex, where Brent has climbed from a monthly low near $79 a barrel in early August to around $94 a barrel by August 20, a recovery that is feeding directly into feedstock costs and reinforcing the reluctance of producers to ease off current price levels.
Across the board, light-viscosity SN 150 and SN 500 grades have each firmed by roughly 20 cents on a per-tonne cost basis since the start of the month, while bright stock has moved up by a comparatively sharper 40 cents, reflecting tighter heavy-grade availability out of key Asian export hubs.
A Market Pulled in Two Directions
What stands out this week is the gap between how sellers and buyers are reading the same set of facts. Producers are inclined to keep offers firm, wary of releasing volume into a market where feedstock and logistics costs out of the Gulf remain unsettled. Buyers, on the other hand, are largely sticking to filling only their immediate order books, unwilling to commit to forward volumes at current levels while they wait to see whether the standoff between Washington and Tehran moves toward any kind of resolution.
This has left overall trading volumes thin. Sellers are reluctant to discount given the uncertainty over their own replacement costs, while purchasers are equally reluctant to lock in cargoes they suspect could come cheaper in a few weeks. The result is a market that is technically rising in price but doing so without much conviction behind it a classic case of a nervous rather than a genuinely bullish market.

Middle East Supply Under the Microscope
Much of the underlying anxiety traces back to how Gulf-based refiners are running their base oil units. Several major Middle East producers continue operating largely on a demand-pull basis tied to Asian offtake, rather than building inventory ahead of need. With the geopolitical backdrop between the US and Iran still unresolved, shipping routes through the region carry an added layer of risk premium, and refiners appear cautious about running plants at full tilt without clearer visibility on how buyers will respond.
This caution on the production side is compounding the caution on the buying side. Asian importers, many of whom are already sitting on lean inventories heading into the next seasonal demand window, are watching the situation closely. Should the standoff escalate or shipping through the region face further disruption, the current price firmness could turn into a sharper spike rather than the gradual climb seen so far this month.
Margin Pressure Building Downstream
For producers, the bigger challenge may not be securing higher prices at the export terminal but making those higher costs stick once the product moves downstream. Buyers who are only willing to transact on immediate, confirmed orders are in a weak position to absorb further increases, which means blenders and formulators further down the chain are the ones left absorbing squeezed margins. Several producers are reportedly holding prices steady rather than pushing them further upward, preferring to first gauge how the current cost environment settles before committing to another round of increases.
This dynamic is being felt most acutely by buyers who came into the month with lower-than-usual stock levels. With seasonal lubricant demand typically picking up in the months ahead, thinner inventories leave these buyers more exposed to further cost increases than they might otherwise be, even as they remain reluctant participants in the current price environment.
Crude-Base Oil Correlation Note: Brent’s August trajectory, a trough near $79/bbl on August 4 to August 5 followed by a near-linear recovery to $94/bbl by August 20, represents an approximate 19 per cent intramonth swing, with WTI mirroring the pattern from $75.19 to $87.00. This volatility directly conditions base oil feedstock economics, since vacuum gas oil and vacuum residue, the primary base oil feedstocks, are priced off the crude complex. As Brent recovered through mid-August, refiners’ marginal cost of base stock production rose in tandem, compressing crack spreads unless base oil offer prices adjusted upward proportionally. The observed 20-cent/kg rise in SN 150 and SN 500, and the sharper 40-cent/kg increase in bright stock, is broadly consistent with this feedstock cost pass-through, though the bright stock premium also reflects tighter heavy-grade fractionation yields under current refinery run patterns amid Gulf-region supply caution.
Currently Operating Producers and Technology Licensors
