Subscriber note: Platts proposes change to US ethylene, propylene assessments basis

Platts proposes changing the basis for the US ethylene and propylene assessments from a three- to 30-day basis to current delivery month and a next delivery month effective April 1. Based on market feedback, the three to 30-day timing window is not reflective of the US olefins spot market as the primary delivery mechanism for both ethylene and propylene in the US is via pipeline, and follows pipeline scheduling. Based on industry feedback regarding pipeline delivery scheduling, Platts proposes that current delivery month roll into next delivery month three calendar days prior to the end of the month. If this day falls on a weekend or holiday, Platts will roll its US olefins assessments to the next month on the next business day. For example, Platts would roll the April assessment into May as the current delivery month on April 29, as April 28 is a Sunday.
