Rubber futures in Tokyo and Shanghai declined to the lowest level since 2009 on concern that slowing economic growth in China will reduce demand from the top user amid a global surplus. The contract for delivery in September on the Tokyo Commodity Exchange lost 4 percent to settle at 206.4 yen a kilogram ($2,016 a metric ton), the cheapest since October 2009. Rubber for delivery in the same month on the Shanghai Futures Exchange dropped 4.1 percent at 14,200 yuan ($2,282) a ton, the lowest close since April 2009. Source
