La méthodologie Platts encadre la façon dont le brut est coté au quotidien : Behind every oil price lies a methodology. Platts, the global benchmark for price assessment, regularly adjusts the cargo sizes it factors into its quotations. A technical parameter with very real consequences for buyers. Here's a breakdown.
The benchmark prices that guide global oil transactions do not appear out of thin air: they are the result of a rigorous methodology. Understanding how these assessments are built helps you negotiate your supply more effectively.
What is cargo size in a price assessment?
To assess the price of a crude, agencies like Platts rely on transactions involving standardised volumes. These benchmark cargo sizes — expressed in thousands of barrels — reflect actual market practice. When they change, it is a sign that logistical habits are shifting.
Why these adjustments matter
A change in benchmark cargo size has several concrete implications for buyers:
- it alters the liquidity and representativeness of the quotations used in contracts;
- it reflects shifts in supply for certain specific crudes;
- it can influence the premiums and discounts applied during negotiations.
What this means for your purchasing strategy
Tracking the methodological changes made by price-reporting agencies means giving yourself the means to better understand posted prices and to secure fair terms. Savvy buyers factor these parameters into discussions with their suppliers.
Key takeaways: benchmark cargo sizes shape crude quotations. Their adjustment by Platts affects liquidity and premiums. A technical parameter worth watching to buy well.

Platts methodology: a benchmark for your purchasing negotiations
The Platts methodology, developed by S&P Global Commodity Insights, structures reference price formation across oil markets. It precisely defines assessment windows (Market on Close), standard cargo sizes, and the specifications used to establish comparable quotations from one day to the next. Understanding these rules is essential for any buyer: these are the benchmarks, alongside Argus, used to index the majority of crude and refined product contracts. Analyses from Platts and news reports from Reuters are key references for tracking these benchmarks.
In practice, the cargo size assessed under the Platts methodology affects price differentials: a full-size lot is valued differently than a part cargo, with a premium or discount applied depending on quality delivered. Mastering these mechanisms helps negotiate fair differentials and avoid paying an unjustified premium on your supplies.
