Benchmark Tokyo rubber futures fell more than 2% to a one-week low on Thursday, as investors took profit from the recent rally after the yen's sharp rise against the U.S. dollar and a drop in Tokyo equities.
The Tokyo Commodity Exchange (TOCOM) rubber contract for May delivery <0#2JRU:> finished 4.1 yen, or 2.4%, lower at 168.5 yen (US$1.38) per kg. It hit a low of 167.8 yen, the lowest since Dec. 3, earlier in the day.
"TOCOM was hit by the yen's surge," said Toshitaka Tazawa, an analyst with Fujitomi Co.
"Plus, investors wanted to book profits after a relatively quick climb over the past few weeks," he said.
