OPIS Launches its Los Angeles CARBOB GATX Assessment to Provide West Coast Storage-Barrel Transparency
New daily price assessments capture the value of CARBOB storage barrels at GATX in Los Angeles, supporting market participants amid shifting West Coast product flows.
[Rockville, MD] – [May 14, 2026] – OPIS, a Dow Jones company and the leading provider of energy pricing, news and market intelligence, today announced the launch of its Los Angeles CARBOB GATX price assessment, expanding its West Coast refined spot benchmarks with a new daily view of storage-barrel value in Los Angeles.
The introduction of the Los Angeles CARBOB GATX assessment comes as the West Coast market continues to adjust to recent refinery closures in California and the resulting increase in refined product imports into the state. In this environment, OPIS is responding to demand for a storage-barrel assessed price to complement existing pipeline-based benchmarks for LA CARBOB.
These new assessments are being introduced at a time when market participants are closely watching potential changes in California inventory regulations, and when transparent storage-barrel pricing can help inform both operational and strategic decisions.
Delivery in OPIS products and workflows
The Los Angeles CARBOB GATX assessments will be available through a range of OPIS products and delivery channels, including:
- The OPIS West Coast Spot Market Report on Context – both the online platform and PDF reports, covering the snapshot and full report formats
- The OPIS Spot Ticker, including the main screen and deal log for real-time trade and assessment visibility
- Via API, standard text and raw files that connect to OPIS West Coast spot reports and support downstream customer systems and analytics
These additions build on OPIS’ long-standing role as a benchmark provider for U.S. West Coast refined spot markets, supporting refiners, wholesalers, traders, retailers and other stakeholders across the fuel supply chain.
