Oil prices fell around 2 percent in Asian trade on Wednesday, as a stronger-than-expected build in U.S. crude oil stocks and weaker U.S. manufacturing data fueled a rout in prices that started in the previous session. Brent and U.S. crude finished around 8 percent lower on Tuesday to end a 25 percent three-session surge, the largest three-day gain since 1990. This roller-coaster volatility could continue especially if there are similar wild swings in the equity markets, said Ric Spooner, chief market analyst at Sydney’s CMC Markets.
