Tokyo Commodity Exchange (TOCOM) futures edged lower on Wednesday, as concerns over trade wars deepened after US President Donald Trump said a trade deal with China might have to wait until after the 2020 presidential election.
TOCOM's rubber contract for May delivery finished 0.3 yen lower at 188.7 yen ($1.74) per kg.
“TOCOM came under pressure as Nikkei slid due to growing worries over trade dispute, but the benchmark was holding relatively well due to shortage of warehouse space for rubber in Japan," said Hiroyuki Kikukawa, general manager of research at Nissan Securities.
The most-active rubber contract on the Shanghai futures exchange for May delivery rose 190 yuan to finish at 12,860 yuan ($1,827) per tonne. China's new technically specified rubber (TSR) 20 futures contract was last up 150 yuan at 10,805 yuan per tonne.
The front-month rubber contract on Singapore's SICOM exchange for January delivery last traded at 142.7 US cents per kg, up 0.6%.
