Goldman Sachs analysts cut their outlook for the price of Brent oil and for copper going into 2012, saying that they see "a flatter upward trajectory for commodity prices, with increasing risks to both the up and the downside."

Analysts lowered their price forecast for Brent to $120 per barrel for next year from a previous $130 per barrel forecast and also said they expected the spread between Brent and WTI crude prices to lower to $16 per barrel over three months, $13 in six months and $6.50 in a year.
