SINGAPORE, Feb 27 (Reuters) – China plans to launch a yuan-denominated gold fix this year to be set through trading on an exchange, sources familiar with the matter said, as the world’s second-biggest bullion consumer seeks to gain more say over the pricing of the precious metal. The Chinese benchmark would be derived from a new 1 kg contract to be launched on the state-run Shanghai Gold Exchange, a senior source directly involved in the process told Reuters. China, also the top producer of gold, feels its market weight should entitle it to be a price-setter for bullion and it is asserting itself at a time when the established benchmark, the century-old London fix, is under scrutiny because of alleged price-manipulation.
