PRICING NOTICE: Amendment to frequency of cobalt hydroxide index, min 30% Co, cif China

After a consultation period, Fastmarkets has amended the frequency of its cobalt hydroxide index, min 30% Co, cif China to weekly.

The cobalt hydroxide index, min 30% Co, cif China was published on the last working day of the month until the end of July, and has been published fortnightly since August 7.

Fastmarkets has seen a sustained increase in spot activity for fixed-price, prompt cobalt hydroxide deals amid persistent spot supply constraints stemming from logistics disruptions in Africa. Furthermore, during times of uncertainty for the outlook of the benchmark price for cobalt standard grade, in-whs Rotterdam, against which payables are settled, buyers have sought fixed hydroxide prices in an effort to cut their exposure to metal price volatility.

The base specifications for the cobalt hydroxide index are as follows with increased frequency marked in italics. As per the earlier consultation, the publication timing has also been brought forward to between 2pm and 3pm London time, aligned with the deadline for other minor metals, ores and alloys prices published from London on Fridays.
