SUBSCRIBER NOTE: Platts to use Japan spot aluminum premium to calculate China All-In Price

Following a period of industry feedback, S&P Global Platts will use the daily Japan spot aluminum premium assessment (MMANA00) as a component to calculate its daily China All-In aluminum published prices in Yuan/mt (MMBAB00) and in $/mt (MMBAA00), beginning November 1, 2017.

The China prices are currently using the weekly South Korean aluminum premium (MMAMX00) as a component for calculation. The final publication of the China price using the South Korean premium will be on October 31, 2017.

Market participants have provided feedback affirming earlier Platts research that the Japan spot premium is the more recognized benchmark for aluminum trades in Asia, while the significance of the weekly South Korean spot premium has reduced. It is also more relevant to use a daily premium to calculate a daily price. Any further questions or feedback should be directed to yuencheng.mok@spglobal.com and pricemethodology@spglobal.com.
