Copper futures hit a 3-month low after the Chinese government released a communiqué regarding the decisions made during the Third Plenum, The Wall Street Journal reported. The slide showed that investors have little faith in the government to boost the metal market. On Wednesday, copper fell 2.3% to US$3.1595 a pound on the Comex division of the New York Mercantile Exchange, the lowest price since July 31. Economic reforms are widely seen as necessary for China to revive economic growth. Copper prices are tied to China’s fortunes, as the country accounts for 40% of global demand for the metal.
