The downward base oil price trend triggered by growing supply levels in Asia along with lackluster demand was partly stalled by climbing crude oil and feedstock prices. Not only has the conflict in Iran not been resolved, but crude oil shipments out of the Middle East have seen increased disruptions as Iran-backed Houthi rebels have attacked vessels and energy facilities in Saudi Arabia and the Red Sea, sending crude oil prices to fresh highs. The persistent shortage of API Group III base oils and expectations that the situation will not be improving soon continued to place upward pressure on prices in this segment in particular. Upcoming holidays in China, Japan and South Korea next week dampened discussions as well.
On Friday, Houthi rebels gained control of the strategic Red Sea port city of Mokha in Yemen and have reportedly seized the strategic Perim Island in the Bab al-Mandab Strait, pushing out forces allied with the Yemeni government–which is backed by Saudi Arabia–just days after hitting energy facilities in the southern part of Saudi Arabia, The New York Times reported. The Saudi Energy Ministry said on Friday that its East-West Pipeline, which had been used to bypass the Strait of Hormuz, had been “targeted multiple times” by drone attacks launched from Iraq and had been shut down as a “precautionary measure.”
Crude oil prices surged following news of the pipeline shutdown on growing fears of increased oil supply disruptions, with Brent crude trading almost 3% higher near $107 per barrel on Sunday and West Texas Intermediate futures close to $103/bbl.
The International Energy Agency has cut its global oil supply forecast for this year, citing “the protracted US-Iran diplomatic standoff” as a main driver. An IEA report released on Friday predicted that the world oil supply would fall to 100.7 million barrels per day in 2026–down 5.7 million barrels a day from the previous year.
Group I
Group I spot prices were holding at largely unchanged levels from a week ago as participants assessed the market situation and awaited developments in the Middle East. With Saudi Arabian oil shipments increasingly under threat of Houthi rebel attacks, Asian producers worried about potential crude supply shortages and climbing oil and fuel prices. This situation has partly influenced their decision to offer only smaller spot base oil cargoes so as to protect inventories and continue meeting contractual obligations.
But the more restricted availability did not seem to be a problem, as buyers appeared interested in securing only those volumes needed to run day-to-day operations and refrained from purchasing large lots.
Indian buyers may have been an exception, as more buying interest has been detected in this country following a period of sluggish demand due to the monsoon season. With inventories close to being depleted, Indian consumers have returned to the market in search of additional cargoes, aside from those they are able to secure from domestic suppliers.
Imported Group I SN150 and SN500 cuts and bright stock CFR India prices were steady from last week because of more limited spot supplies, and even though the restrictions would normally have pushed prices up, the presence of competitively-priced domestic supplies kept import indications from edging up. Climbing crude oil and feedstock values offered support to Group I prices as well.
Domestic refiners kept prices steady in India during the week. Sanctions on Iranian imports kept prices for products from this origin at unchanged levels from the previous week. India also imports large amounts of base oils from Saudi Arabia, but shipments may see disruptions or longer lead times due to the need to reroute vessels through the Suez Canal.
Meanwhile, some offers from Southeast Asia have elicited keen interest from regional buyers. The key Thai producer was heard to have offered additional cargoes last week, which were swiftly snapped up. Flexibag volumes of SN150 were understood to have been offered at around $1,420/ton FCA Thailand, SN500 at $1,400/ton FCA and bright stock at $1,585/ton FCA Thailand, for September loading. The producer did not offer any cargoes this week. Offers from the refiner have been on and off during the last several weeks due to crude oil and feedstock supply concerns, particularly in view of the shipping turmoil in the Red Sea and ongoing Houthi rebel attacks on vessels and production facilities in Saudi Arabia.
There was limited availability from a second Thai producer, while an Indonesian refiner closed a tender on September 7 that involved small quantities of the Group I light grade for second half Sep. loading. Two small bright stock cargoes of Thai origin were also reported as having been secured by Chinese buyers for September shipment during the week.
Buying appetite for imports in China has been lackluster as buyers felt they could not offset the steeper prices by increasing lubricant values, as demand has not been robust and uncertainties lingered. Consumers preferred to purchase local products, and this incentivized producers to increase prices. Additionally, some buyers had delayed purchases for as long as possible and they have returned to the trading table to replenish stocks. Climbing crude oil prices and no prospects of a quick resolution to the Iran conflict also offered support to domestic prices.
One exception in terms of domestic prices may be bright stock, with a Chinese supplier having adjusted prices down to compete with imports, as they appeared to be plentiful since several bright stock cargoes from Southeast Asia had been imported in the previous two months. Indications from other producers were generally steady. The restart of Karamay Petrochemical’s plant in the second half of Sep. may bring more spot volumes to the market.
Group II
Group II base oil prices were exposed to downward pressure, despite the crude oil and feedstock price spikes. Lengthening supplies and slowing demand — with the exception, perhaps, of India — amid uncertainties in downstream markets continued to drag base oil prices down. Consumers were conservative in terms of acquiring products as they preferred to avoid keeping high inventories that may lose value in the coming weeks. The heavy-viscosity grades were more readily available than their light-vis counterparts and this was reflected in lower pricing.
The sole Taiwanese Group II producer was expected to be building inventories to cover contract commitments during a turnaround scheduled to start next month, with spot supplies likely to be more limited over the next couple of months. The shutdown was expected to start in mid-October and be completed in early December. Shipments to China from Taiwan were heard to have increased in August as contract customers seemed anxious to secure needed volumes as the producer’s shutdown was looming.
There have been some spot offers coming from the Taiwanese supplier in the last few weeks, but it could not be ascertained whether the supplier was sold out. The producer’s domestic list prices have remained unchanged in September, and its discounts for formula-linked accounts were rolled over into October.
The availability of Taiwanese material and of other imported cargoes has assuaged concerns about potential supply shortages in China. In fact, there was talk about cargoes possibly being re-exported as demand was not strong enough to absorb imports and domestic supplies as well. The high premiums of imports were an added incentive to look for alternative markets for these cargoes.
Domestic suppliers have also increased posted prices given a pickup in demand as some buyers had depleted their stocks, and the steeper values may make arbitrage opportunities more difficult to work. At the same time, climbing crude oil and feedstock prices discouraged producers from offering discounts, particularly as there seemed to be fewer chances for the Iran conflict to be resolved quickly, keeping steady pressure on feedstock costs. An upcoming shutdown at a Group II plant in mid-November may reduce availability in the coming months as well.
Asian suppliers whose inventories have grown in recent weeks have set their sights on India, and have lowered their offer levels to entice Indian buyers. With the exception of the Group II 70N, which was heard to have inched up by $20-30/ton CFR India on firming feedstock costs, Group II import prices have slipped by around $20/ton on a CFR India basis. Blenders were expected to replenish stocks as these have been run down over the previous months given subdued buying activity during the monsoon season.
The improved amounts of imported heavy-viscosity material was seen as a blessing at a time when domestic supplies in India have fallen due to refinery yields, which result in higher volumes of the light grades, and because one producer was focusing on producing more Group III grades, which offered firmer netbacks given a global supply scarcity of Group III cuts.
South Korean Group II offers were also heard to continue to attract attention at destinations in the Americas. However, high freight rates, long delivery times and difficulties in locating vessels to cover the long-distance routes, together with thinning premiums for imported products have made some of the transactions more challenging to complete. The softer conditions in deep-sea markets would allow for more barrels to become available to Asian buyers in the coming weeks.
Aside from the current shipping disruptions, Group II availability from Saudi Arabia may be restricted because of a 30-day shutdown at the Saudi plant in Yanbu from October 1.
Group III
Persistent global Group III supply shortages kept upward presure on prices, but producers have found increasing resistance to further steep price hikes, and the amounts of the increases were more moderate compared to the previous weeks.
Blenders were concerned about demand in downstream lubricant markets amid economic uncertainties and manufacturers’ credit and cash constraints, which may make it difficult to transfer the high base oil costs down the supply chain.
With Iran still effectively controlling the Strait of Hormuz, Group III production in Abu Dhabi, Bahrain and Qatar continued to remain shut down and this kept pressuring prices. Increased turmoil surrounding crude oil shipments from Saudi Arabia and attacks on vessels in the Red Sea only added uncertainty to the base oil supply situation.
Unplanned outages in Europe and current and upcoming turnarounds in other regions were expected to exacerbate the product shortages. The joint venture production site operated by Repsol/SK Enmove in Spain has shut down 4 cSt production and supplies were not expected to recover until November, although the 6 cSt and 8 cSt cuts seemed more plentiful, not only in Spain, but in other regions as well.
A Malaysian Group III producer was understood to have scheduled a 45-day turnaround at its plant in Malacca that started in the second half of August and was expected to be completed in early October. The producer may have restricted spot offers as it was focusing on meeting term commitments during the outage, and it has also slightly curtailed allocations, according to sources, but no updates could be obtained from the producer directly.
In China, offers of imported Group III hovered at steeper levels than domestic supplies, limiting buying interest. A number of domestic producers were focusing on Group III production to the detriment of Group II cuts because of the more attractive prices of Group III grades. However, there were many lubricant manufacturers who had no choice but to accept the current import prices because of formulation requirements.
The Chinese coal-to-liquids (CTL) producer was heard to have started a 25-day turnaround in early September and has therefore restricted spot sales, even though the shutdown was only partial, according to reports.
Asian Group III suppliers were eyeing markets where netbacks were more attractive, reducing supply options for Chinese buyers. Chinese buyers were resisting the higher prices of imported products, because of uncertainties related to being able to recover the high costs from lubricant sales.
In India, the key Indian Group II/Group III producer was understood to be running its Group III production lines at top rates to take advantage of export opportunities given the supply vacuum left by Middle Eastern Group III base oils, with cargoes moving to overseas destinations including the U.S., according to sources. This has limited its Group II availability too.
Group III 4 cSt, 6 cSt and 8 cSt import prices edged up by $20/ton on a CFR India basis reflecting international prices amid ongoing supply shortages, but the price ascent seemed to have slowed down compared to previous weeks. Buying interest was somewhat subdued as blenders were not sure that they would be able to recoup costs by increasing lubricant prices, and many preferred to source domestic products whenever they became available. Some consumers continued to procure Group II base oils to replace Group III grades if formulations allowed.

Production
Middle East Plants
Qatar Energy halted production of liquid natural gas and other products following drone attacks on its facilities in Ras Laffan and Mesaieed in early March. The facility will not be able to return to normal production for several months, and has declared force majeure on LNG shipments, according to the company’s website. One train at the Shell/Qatar Petroleum Pearl gas-to-liquids base oil unit in Ras Laffan, which suffered some damage during an attack as well, was heard to be shut down. The unit utilizes natural gas from the Qatar Energy refinery to produce Group III base oils. The plant has a nameplate capacity of 1,372,000 tons of Group II/Group III base stocks. The damaged train was expected to remain shut down for several months, possibly a year, until repairs to the highly specialized equipment are completed.
Fire erupted at Bapco’s refinery in Maameer, Bahrain, on March 5 following an Iranian attack. The country’s Ministry of Interior reported that the fire had been brought under control without providing further details about potential damages. Bapco operates a 400,000-metric tons per year Group III base oil facility in Sitra, within the Bapco refinery complex. Sources familiar with the plant’s operations said that Group III production was unaffected by the fire, but some reports indicated that production had stopped for damage assessments. An official report was not available by the publishing deadline.
In Abu Dhabi, United Arab Emirates, a suspected drone strike had triggered a fire at the Ruwais Industrial Complex, leading authorities to shut down the country’s flagship refinery as a precautionary measure on March 10. The Ruwais complex houses ADNOC’s Group II and Group III base oils plant. According to sources familiar with ADNOC’s operations, the base oil unit was not damaged during the drone attack as only one train of the refinery had been affected by the strike, although it was reportedly running at reduced rates. The producer appeared to have been able to maintain base oils output for its own downstream lubricant operations. The latest information indicates that ADNOC was preparing to ramp up production following news of a ceasefire in the Middle East in late June, although these plans have been derailed by a resumption in hostilities and renewed closing of the Strait of Hormuz on July 8. The distributor of ADNOC material in the U.S. was compelled to declare force majeure on contract shipments as no fresh base oil cargoes have been able to be lifted in Abu Dhabi.
The latest plant turnaround information for 2026 is provided below, along with plant shutdowns that took place in the second half of 2025 as they may have impacted base oil pricing at the time of completion and beyond.
Group I
- Luberef postponed a 30-day turnaround at its Group I/Group II plant in Yanbu, Saudi Arabia, from August to October 2026. The shutdown will only affect Group II production, according to sources. The company had previously completed maintenance at the unit from mid-November until December 2025.
- Luberef has secured a new feedstock supply agreement for the company’s Jeddah facility. The facility had been expected to close by mid-2026, but the new supply agreement will allow it to continue operations beyond 2026. As a result, the company will maintain its current production capacity of 275,000 tons per year of Group I base oils. With the completion of the Growth-II Project in Yanbu, Luberef’s total production capacity will reach 1.53 million tons per year, making it the only supplier in the region able to offer Group I, Group II, and Group III base oils.
