Raw materials from Brent crude to wheat, cotton and metals fall in unison, paring strong gains made since mid-March on lost oil output in Libya and steep falls in agricultural stocks.
On November 1st the NYMEX opened an open-outcry pit in Dublin to handle Brent crude futures, the benchmark contract for pricing two-thirds of the world's oil.
Brent was pushed higher amid reports of a militant attack on a Chevron-operated offshore oil facility in Nigeria's oil-rich Niger Delta region as well as news of supply disruptions in Libya.
