Tokyo rubber futures marked a five-month closing peak on Monday on higher oil and other commodity prices, though their strong momentum waned later in the day as rising domestic inventories eased supply concerns. The key Tokyo Commodity Exchange rubber contract for March delivery, which debuted on Monday, settled at 311.1 yen per kg, the highest since late April, after climbing to 314.7 yen.
The settlement level was down 0.6 percent from the opening price of 313.1 yen. The most actively traded February contract settled down 0.1 yen at 309.1 yen. "As domestic inventories are rising, supply concerns have eased, capping the upside in the rubber market," a trader said.
