Platts to use same-day LME data in China copper cathode all-in calculations, change publishing schedule

Platts, part of S&P Global Commodity Insights, will use London Metal Exchange (LME) prices from the same day to calculate its CIF China copper cathode fixed price equivalent (all-in) prices, effective May 2.

The all-in prices currently add premiums or discounts assessed by Platts to underlying LME settlements from the previous day or the latest available value. The change to using same-day LME prices will ensure that the all-in calculations reflect the most current market values.

Platts will also revise its publishing schedule for China copper all-ins, moving from the Singapore holiday calendar to a schedule that follows Singapore and UK calendars. Under this change, the all-in calculations will be published on days that are working days in both Singapore and the UK.

The daily Platts Copper Spot Premium CIF China (MMAMK00), used in the calculation of the all-in prices, will continue to be published based on the Singapore holiday calendar.

The monthly averages of the all-in prices will be calculated based only on the days when the all-in values are published.

The following all-in prices will be impacted:
