Crude trades flat; brent holds $115 mark

Oil prices are trading flat after a volatile session yesterday. There was a sharp intra-day surge on reports of unrest in the world's largest oil exporter, Saudi Arabia. However, fears persisted that prolonged conflict in Libya could do long-lasting damage its oil infrastructure. The dollar's strength on renewed euro zone credit worries also put pressure on prices. Brent though continues to hold the USD 115 mark in Asia trade this morning.

Copper dropped to its lowest level in 2 months on soft Chinese trade data led to worries about slackening demand in China.
