Shanghai Natural Rubber futures rose by 31.41% or 7,725 yuan/ton since the beginning of this year, and rose by 273.43% since December 8, 2008. The historical high was RMB 33,230/t set on October 26, 2010, and the high before the financial crisis was RMB 28,570/t set on June 27, 2008. However, Tokyo Rubber has performed relatively weakly. Its high this year was 343.3 yen/kilogram, which was set on October 26. It was lower than 356.9 yen/kg before the financial crisis (June 30, 2008).

According to industry analysts, the continued rise in rubber prices has been related to factors such as the general increase in global commodity markets, rapid growth in automobile sales, and natural disasters in the climate. In particular, the recent impact of heavy rains, Hainan's natural rubber production is expected to reduce 20,000 tons, coupled with 20,000 tons drought reduction in Yunnan, the domestic supply has been tight. Hainan was hit by heavy rain in the near future, making investors in the futures market nervous.
