GOLDMAN SACHS: Here's Our Outlook For 14 Key Commodities

Mounting controversy and alleged market manipulation has led Washington legislators to take a stronger look at major banks' hold over commodities, with the Fed to possibly reevaluate regulation in the coming months.

But for investors, the case for holding commodities as a strategic move is still clear, according to Goldman Sachs commodity strategist Jeffrey Currie.

Currie tells clients three reasons why: "1) commodities as a hedge against hostile markets amid rising geopolitical risks, 2) significant roll-yields on the back of the tightness in Cushing which will likely support backwardation in energy markets into the autumn, and 3) an increasing decline in correlations across returns, both within commodity markets and against other asset classes, making the case for commodities investments as a way to diversify portfolio risk."
