Chinese industrial production fell to a four-month low in March, according to HSBC's preliminary manufacturing index released Thursday. China is the world's second biggest consumer of oil behind the U.S.
"Weakening domestic demand continued to weigh on growth," HSBC said in a report. "China's slow down has yet to finish."
Crude has hovered between $105 and $110 for the last month, up from $75 in October, amid the possibility that a military strike by Israel or the U.S. on Iran's nuclear facilities could disrupt global supplies.
The jump in oil prices in recent months has increased the price of gasoline and other crude products and raised fears in Asia that inflation could quicken. Inflation concerns have kept policymakers from implementing aggressive stimulus measures despite signs of slowing economic growth, said Irvin Seah, an economist with DBS bank in Singapore.
"Oil prices will hit everyone, which is why despite the downside risks to growth, Asian central banks have been standing back rather than cutting interest rates," Seah said.
