Benchmark Tokyo rubber futures hit their highest in more than two weeks on Tuesday, buoyed by firm Shanghai futures and a weaker yen, which makes yen-denominated assets more affordable when purchased in other currencies. The Tokyo Commodity Exchange rubber contract for October delivery finished up 6.1 yen at 221.7 yen ($1.98) per kg. Earlier in the session, it hit 223.9 yen, the highest since April 14. The most-active rubber contract on the Shanghai futures exchange for September delivery rose 515 yuan to finish at 15,245 yuan ($2,211) per tonne, after hitting as high as 15,345 yuan, the highest since April 12.
