Asian Group II N500 base oil prices drop

Prices for Asian supplies of Group II N500 have slipped below Group I SN 500 prices, because of plentiful supplies of the former while Group I supply availability remains scant.

Asian Group II N500 fob export prices fell to a discount of $10/t to Group I SN 500 in the week to 25 July. This follows a recent trend of narrowing premiums for Group II to Group I base oils.

Group II neutrals are typically priced at a premium to Group I volumes because of more complex refining processes that create base oils with enhanced characteristics such as higher purity, improved viscosity index and better antioxidation properties.

N500 prices last dropped below SN 500 in August 2024.

Group II supplies increase

Group II heavy neutral prices have been decreasing steadily from an over two-year high of $1,000/t fob Asia in March because of plentiful availability. Supplies increased after a key south Korean refinery completed a scheduled turnaround in late April. Some regional refineries have been incentivised to maintain elevated output of heavy neutrals because of a strong premium to light neutrals, keeping N500 supplies plentiful. The premium for Asian fob export prices of Group II N500 to N150 hit $280/t in the week ending 11 April — the highest since early October 2021. The premium has since lowered to $220/t in the week ending 25 July, but remains higher than the five-year average of about $147/t.

In contrast, SN 500 supplies remain scant, which drove prices to a 51-week high of $940/t fob Asia in the week ending 18 July. Offers from various northeast Asian and southeast Asian producers remain curtailed because of scheduled maintenances.

Most market participants do not expect SN 500 to hold a sustained or large price premium to N500, despite a global trend of falling Group I and expanding Group II production capacity. N500 has held an average premium of about $26/t to SN 500 over the past year.

Most regional blenders remain unwilling to pay a premium for Group I over Group II, particularly where they are able to substitute Group I with Group II base oils in their lubricant formulations.

The marine sector is an exception that has not fully pivoted away from Group I base oils, because of their higher viscosity and solvency. But marine lubricant demand is steady or subdued — in line with lower bunker sales. Bunker consumption at the port of Singapore over January-June edged down by 0.8pc on the year to 27mn t, according to preliminary data from the Maritime Port Authority of Singapore.

Thai spot offers are anticipated to return in late August after the completion of maintenance at a Thai refinery, which would help ease Group I tightness.

Southeast Asian heavy grade suppliesare also expected to grow in the second half of the year with additional capacities coming on line, and this is likely to weigh on prices of Group I and II heavy grades.
