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

HIGHLIGHTS

Proposed changes would apply to CIF China copper cathode all-in calculations

Publishing schedule for CIF China copper cathode spot premium would be unchanged

Platts, part of S&P Global Commodity Insights, is proposing to 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 would ensure that the all-in calculations reflect the most current market values.

Platts is also proposing to 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 would 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, would continue to be published based on the Singapore holiday calendar.

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

The following all-in prices would be impacted:

Platts CIF China copper assessments are published on pages MTL0106, PMA0106, MTL0419 and PMA0419 of the Platts Nonferrous Metals Alert, Platts Metals Daily and in the Platts price database.
