· US Group II base oils prices stay in unusually narrow range versus vacuum gasoil feedstock prices throughout most of this year.
· US Group II base oils domestic price-premium to export prices similarly stays in relatively narrow range so far this year.
· US Group II heavy-grade price-discount to prices in markets like India similarly holds in relatively narrow range throughout most of this year.
· Steady US price-spreads contrast with more volatile margins and price-differentials in recent years.
· Steady US price-differentials point to unusually prolonged period of balanced supply-demand fundamentals.
· Domestic and overseas demand is sufficiently strong to absorb US' higher base oils output in June-July 2025, leaving stocks tight in first seven months of the year.
· Steady domestic base oils margins partly reflect support from steady domestic-export price-spread.
· Steady domestic-export price-spread partly reflects support from steady US price-discount to prices in markets like India.
· US Group II heavy-grade price-discount to CFR India price benefits from higher outright India cargo price amid tight supply in Asia in H1 2025 especially.
· High CFR India price curbs pressure on US export price to fall any further, while tight supply in Asia boosts demand for US shipments.
· India’s imports from US duly rise by 40% in first nine months of 2025 from previous year.
· Steadier US export price and regular removal of surplus supplies from domestic market curb downward pressure on US domestic price.
· US posted prices typically fall around this time of year in response to weaker demand and rising surplus supply.
· Lack of any widespread round of posted price cuts so far in Sept-Oct 2025 suggests that US supply-demand fundamentals remain relatively balanced.
· Balanced fundamentals partly reflect tighter-than-usual supply in Asia in H1 2025 and persistently strong demand in Mexico, balancing out weak domestic demand.
· Those supportive factors are now set to change.
· Asia’s supply begins to recover during Q3 2025 following completion of most plant-maintenance work.
· Supply set to get further boost from start-up of new base oils unit in Singapore in Sept 2025 and in India in late-2025.
· Mexico’s demand could face at least short-term impact from recent introduction of stricter rules on imports into the country.
· Mexico’s base oils imports consistently far exceed country’s domestic lube demand.
· Any narrowing of gap between imports and domestic lube consumption would impact demand for US base oils.
· Unusually steady US base oils price-differentials through most of this year partly reflect balanced-to-tight fundamentals, especially compared with recent years.
· Change in US supply-demand fundamentals could in turn prompt reversion of US price-differentials to trends similar to the ones they faced in recent years.
