Tokyo rubber gains on March 12

Tokyo Commodity Exchange (TOCOM) futures, which set the tone for rubber prices in Southeast Asia, rose 1 percent on Tuesday, as strong gains in global stock prices helped boost risk appetite among investors.

The benchmark Tokyo Commodity Exchange (TOCOM) rubber contract for August delivery finished 2.0 yen, or 1.0 percent, higher at 199.2 yen ($1.79) per kg.

The most-active rubber contract on the Shanghai futures exchange for May delivery rose 20 yuan to finish at 12,165 yuan ($1,813) per tonne.

TOCOM's technically specified rubber (TSR) 20 futures contract for September delivery closed up 1.2 percent at 170.3 yen per kg.

The front-month rubber contract on Singapore's SICOM exchange for April delivery last traded at 146.3 US cents per kg, up 0.4 percent.

"Investors' risk appetite recovered amid a rally in global equity markets," said Hiroyuki Kikukawa, general manager of research at Nissan Securities. "Some investors rewound their short positions ahead of a crucial vote in the British parliament on a Brexit withdrawal deal," he added.

British Prime Minister Theresa May won legally binding Brexit assurances from the European Union on Monday in a last ditch attempt to sway rebellious British lawmakers who have threatened to vote down her divorce deal again.
