Argentina’s base oils supply fell into deficit in July for the first time in three months, with the shift pointing to leaner stocks rather than a supply squeeze as domestic production continued to cover most requirements.

Supply lagged demand by close to 3,000 cubic metres (2,600 tonnes) in July, reversing a surplus of around 3,000 cubic metres in June and one of more than 10,000 cubic metres in May, Ministry of Economy data showed.

Domestic output fell to a five-month low of less than 8,000 cubic meters, while imports remained well below typical monthly levels.

Supply fell against the backdrop of an ongoing slide in domestic lubricants consumption, which allowed the market to rebuild surplus volumes during the previous two months despite overseas supply disruptions.

Weaker demand, sufficient supply and the country’s ability to cover most of its requirements made leaner stocks more acceptable to buyers, mirroring a similar trend in a growing number of other markets.

Key Highlights

·         Domestic output covered 75% of supply in July, up from 74% of supply in the first seven months of the year, 66% in all of 2025 and 60% in 2024.

·         Imports from the US accounted for 86% of Argentina's total imports, the highest share in three months and above the typical 74% share of the past year.

·         Base oils stocks fell for a second straight month to a three-month low.

·         The tighter balance coincided with a pause in cargo-sized exports in August after a resumption of such shipments in July.

Market Repercussions

Argentina’s supply remained more than sufficient earlier this year even when concerns about disruptions triggered a surge in demand that instead left the market with a growing surplus.

 Sufficient availability even through unexpected disruptions leaves buyers with less need to hold large stocks, allowing them revert to a strategy of running inventories against underlying demand rather than as a precaution against supply risk.

The shift raises a risk of moving from excessive caution to insufficient inventories. Domestic production covers most of Argentina’s requirements, but a large share of it comes from a single refinery.

Argentina has had less need than more import-dependent markets to diversify its supply sources because domestic production has covered most of its requirements. This year’s disruptions showed the value of having alternative sources, and the risk of an overreliance on one or two of them.
