Axios/Business Insider/ Getty Images Goldman Sachs has bought agwest commodities book for about $6 billion, the Wall Street Journal reports.

The investment firm’s acquisition of the book comes as the commodities market continues to taper amid a glut of cheap oil and a weaker dollar.

The book, published in English, will be the largest acquisition of a commodity book in history, according to the WSJ.

Goldman Sachs bought agWest in 2014 for $3.1 billion.

The commodities market is in the midst of a severe correction and there is no clear signal that the market will bounce back.

The current low of $US4.60/tonne has not been above $US6 since late October, the day after the Fed announced its second round of bond-buying.
