Commodities continued their descent today as mounting fears about the outlook for the global economy dented investors' enthusiasm for energy and raw materials.
Oil tumbled another $1.93, or 1.8%, to $105.06 a barrel, bringing this week's decline to 6.1%, before recovering a little to $106.05.
After a day in which commodities tumbled more or less across the board, tin fell by 2.9%, aluminium by 2.6%, lead by 1.0% and nickel by 0.3%.
Gold was a rare exception among commodities, surging by 2.8% at one point, to a fresh record of $1,878.15 an ounce, as investors sought safe havens for their assets.
