Platts to change volume range for Butane FOB West Med Coaster assessment

S&P Global Platts will reflect a volume range of 4,000 mt to 6,000 mt for Butane FOB West Med Coaster (PMAAM00) assessment with effect from February 3, 2020.

The assessment currently includes full or part-cargoes of at least 1,600 mt that are normalized to a 4,000 mt basis.

Platts has observed that typical parcels trading in this market are at or above 4,000 mt, and has received feedback that the current parcel sizes reflected in the assessment are no longer the most fungible.

Following this decision, only trades for parcels within the 4,000 mt to 6,000 mt range will be reflected in the assessment. The basis size of 4,000 mt will remain unchanged, with trades for larger sizes normalized to that basis for assessment purposes.

This decision follows a period of industry feedback. This change was first proposed in a note published December 3: https://www.spglobal.com/platts/en/our-methodology/subscriber-notes/120319-platts-proposes-changes-to-volume-range-for-butane-fob-west-med-coaster-assessment
