World oil prices dived on Wednesday following weak manufacturing data in China, the world’s leading consumer of energy. New York’s main contract, West Texas Intermediate (WTI) for delivery in September, slumped $1.84 to close at $105.39 a barrel. In London trade, Brent North Sea crude for delivery in September sank to $107.19 a barrel, shedding $1.23 from Tuesday’s close. Global banking giant HSBC said its preliminary purchasing managers index (PMI) for Chinese manufacturing hit an 11-month low of 47.7 for July, down from 48.2 in June but still in contraction territory.
