Kuala lumpur: The rubber market closed mixed on Monday amid a stronger ringgit against the US dollar and higher crude oil prices, a dealer said. At 8 am, the ringgit gained against the greenback to 3.9590/9725 from 3.9690/9740 at last Thursday's close. According to BERNAMA News Agency, Brent crude oil prices rose 1.04 percent to US$109.41 per barrel. A stronger ringgit weighed on rubber prices, while higher crude oil prices lent support, resulting in a mixed trend. However, gains were limited by uncertainties over the West Asia conflict and US trade policies, the dealer told Bernama. At 3 pm, the Standard Malaysian Rubber (SMR) 20 price increased seven sen to 866 sen per kilogramme (kg) while latex-in-bulk inched down by one sen to 750 sen per kg.
