The Tokyo Commodity Exchange (TOCOM) rubber contract for January delivery finished 5.6 yen, or 3.7 percent, higher at 158.2 yen ($1.55) per kg, after touching the loftiest since July 29 at 158.4 yen.
The most-active rubber contract on the Shanghai futures exchange for January delivery soared 360 yuan to finish at 13,035 yuan ($1,962) per tonne. The front-month rubber contract on Singapore's SICOM exchange for September delivery last traded at 132.4 US cents per kg, up 1.1 cent.
