Benchmark Tokyo rubber futures ended down 1.3 percent on Friday, weighed down by a stronger yen against the dollar and weak Shanghai futures, brokers said. The Tokyo Commodity Exchange rubber contract for June delivery finished 2.8 yen lower at 209.2 yen ($1.89) per kg, posting a weekly decline of 0.6 percent.
The most-active rubber contract on the Shanghai futures exchange for May delivery fell 135 yuan to finish at 14,065 yuan per tonne. The front-month rubber contract on Singapore's SICOM exchange for February delivery last traded at 153.1 US cents per kg, up 0.4 cent.
Tokyo Commodity Exchange (TOCOM) futures, which set the tone for tyre rubber prices in Southeast Asia, posted a weekly decline, stepping further away from a 3-1/2-month high hit earlier this week. The dollar eased 0.2 percent to 110.86 yen, with its rebound from Wednesday's four-month low of 110.19 fading despite the rise in US debt yields.
