KUALA LUMPUR: Malaysians could face higher unsubsidised fuel prices if global oil prices continue to climb. According to Khairul Annuar, Malaysia’s pump prices are based on the Mean of Platts Singapore (MOPS), which reflects refined fuel prices in the region. “When diesel and RON97 wholesale prices increase, dealers must inject more capital to maintain normal stock levels. The unsubsidised fuel prices in Malaysia may increase if global oil prices climb to between US$80 (RM314.68) and US$100 (RM393.35) a barrel for a prolonged period, say economists and industry players. “Should oil prices hit these rates for a prolonged period, the government might have to raise pump prices gradually to maintain fiscal sustainability,” he said.
