Platts updates the publishing calendar used for the Platts global petrochemical indices

Platts, part of S&P Global Energy, has updated the calendar for publishing the Platts global petrochemical indices to the global publishing calendar, effective Dec. 1, 2025.

This update was first proposed on Oct. 16 in a subscriber note available here and then confirmed in a subscriber note here.

The indices had been following the Singapore publishing calendar.

Starting from Dec. 1, 2025, the indices are published every weekday, apart from the days designated as global holidays, namely Christmas, New Year's Day and Good Friday.

On days when individual regions' inputs are not available due to regional holidays, the index will use the latest databased value for that input.

The description of the global publishing calendar can be found here: https://www.spglobal.com/commodity-insights/en/pricing-benchmarks/our-methodology/holiday

The affected indices appear in Platts Petrochemical Alert on page 900 and in the Platts price database under the following symbols:
