Rapid escalation in base oil costs and availability is creating a pronounced seller’s market in Group III and further testing traditional lubricant pricing models

By Thomas F. Glenn, JobbersWorld

Key Takeaways

• Group III supply is tightening rapidly, with spot availability largely disappearing and growing concerns around production outages and outright shortages
• Prices are escalating in an unstructured, less predictable manner, outpacing Group II increases and becoming more difficult to track across the market
• Traditional pricing mechanisms—including spot-based indexes and cost-plus models—are being challenged as benchmarks lose relevance
• Blenders face growing difficulty pricing finished lubricants as extreme volatility disrupts the industry’s long-standing pricing playbook

The U.S. base oil market is under significant stress, with lubricant blenders reporting rapid escalation in both pricing and supply constraints—particularly for premium Group III base oils. More fundamentally, the current environment is disrupting not only costs, but also the mechanisms by which base oils are priced and sourced.

This volatility is being driven by a combination of direct attacks on Middle East energy infrastructure, severe disruptions to shipping through the Strait of Hormuz, tightening availability of key grades, and broader cost pressures moving through the supply chain.

So far in March, Group II base oils have seen multiple price increases totaling roughly 95 cents per gallon (depending on viscosity grade). While significant, blenders describe the Group II movement as relatively structured compared with the more unstructured and less predictable increases unfolding in Group III.

Prices are escalating in an unstructured, less predictable manner, outpacing Group II increases and becoming more difficult to track across the market.

In contrast, Group III pricing is rising in a less predictable manner, driven primarily by severe tightening of availability. Spot market supply has effectively disappeared for many buyers. “Unless you have strong contacts for Group III, you’re not going to find it,” one blender reported—a sentiment widely echoed across the industry.

Middle East Dependency Amplifies the Risk

The U.S. remains a net importer of Group III base oil, with domestic production covering only a minority share of demand (roughly 30–50% in recent years, even as new capacity ramps up). In 2025, Middle East sources (primarily Qatar, UAE, and Bahrain) supplied more than 40% of total U.S. Group III supply for the third straight year. That share climbed to approximately 55% of U.S. Group III inflows in January 2026 data. Virtually all of these volumes must physically transit the Strait of Hormuz.¹

With shipping through the strait now severely constrained due to the ongoing conflict, the impact on U.S. availability is outsized. Blenders report that if these constraints are not meaningfully resolved in the coming weeks, current supply disruptions could intensify, leading to tighter allocations and, in some cases, limited—or even no—availability of certain Group III grades.

Compounding the logistics crisis are direct strikes on production facilities. Shell’s Pearl GTL plant in Qatar—one of the world’s largest sources of premium Group III+ base oils, with roughly 30,000 barrels per day of base oil capacity—halted production after sustaining damage in mid-March attacks on Ras Laffan Industrial City. One of the two trains was damaged, with full repair of the affected train expected to take approximately one year. The facility was already operating at reduced rates due to prior Hormuz-related export constraints. These combined production and shipping disruptions have pushed spot availability to near zero and placed much contractual volume on allocation.

Even traditional indexed pricing models are being challenged in the current environment, as many rely on spot market benchmarks that may be less representative when spot availability is limited. With little to no spot product available, blenders question how representative those indexes remain. According to some blenders, once recent base oil increases take effect, Group III prices could approach $2.00 per gallon above February levels, prior to the recent Middle East disruptions. The realized increase will vary based on supply agreements, sourcing arrangements, and other commercial factors, with additional hikes already working their way through the market—a pace several blenders describe as unprecedented.

Overall, these conditions have created a pronounced seller’s market in Group III, where pricing is increasingly driven by constrained availability rather than traditional cost-plus structures. Some blenders describe the environment as shifting toward a more “all-in” approach, in which simply securing supply becomes the dominant factor.

Beyond sourcing challenges, the volatility is making it extremely difficult to price finished lubricants. With base oil costs moving so sharply and frequently, the industry’s traditional pricing playbook—built around more predictable adjustments and longer lag times—is becoming increasingly difficult to apply, reinforcing the breakdown in traditional pricing models highlighted in JobbersWorld’s March 19 analysis of market volatility.

South Korea and other non-Middle East sources continue to provide some alternative supply, but they cannot fully offset the scale of Gulf volumes now at risk. Domestic U.S. Group III expansions offer longer-term relief, yet they have not yet shifted the market to majority domestic supply.

Whether the market stabilizes will depend heavily on near-term geopolitical and logistical developments, including progress on reopening safe passage through the Strait of Hormuz and the speed of repairs at damaged Gulf facilities. In the short term (weeks to months), tightness is likely to worsen before it eases.

Taken together, these conditions point not just to a tightening market, but to deepening supply constraints and a broader breakdown in how base oils are priced, sourced, and managed—leaving blenders to navigate an environment where both costs and pricing mechanisms are increasingly uncertain.
