MB quotes are quoted by the independent quotation body of the British Metal Guide (MetalBulletin referred to as MB) on the basis of quotation traders and suppliers. Weekly MB will be reported twice the price. This pricing mechanism is not transparent, easy to lead to market manipulation. Although this pricing mechanism has been criticized, LME also tried to replace the MB cobalt pricing mechanism through cobalt futures, but the actual effect is not obvious.
