All prices on this page are indicative market levels, not firm tradeable quotes. They are derived from live ICE Brent crude futures (Yahoo Finance BZ=F) using Platts-calibrated crack spread formulas that reflect typical refinery processing margins for each product.
Crack spreads are updated dynamically based on the current Brent price level — they widen or narrow as Brent moves, approximating the typical refinery economics for each product grade. The result is a reliable market indicator suitable for commercial reference, but buyers and sellers should obtain firm quotes from verified suppliers for actual transactions.
Price Update Frequency
Prices are refreshed hourly from live futures data. During market closes (weekends, US holidays), prices reflect the last available session close.
