The man who predicted the ongoing financial crisis has another warning.

New York University professor Nouriel Roubini said that because investors will be disappointed in the gradual pace of recovery, he expects commodity markets may drop in the months ahead, Bloomberg.com reported today.

Roubini said the markets have “gone up too much, too soon, too fast” and that he sees the potential for a correction in the market. He pointed to markets realizing that the recovery won’t be rapid and V-shaped, but rather U-shaped, as a reason for the potential correction.

Roubini also pointed to a growing gap that he believes exists between what the markets are doing – the Standard & Poor’s 500 is skyrocketing, up 51 percent from a 12-year low in March – and a real economy that is barely recovering. If economic growth doesn’t rebound rapidly, he feels the markets will flatten out.

The global economy will expand 3.1 percent in 2010, the International Monetary Fund predicts. Roubini, however, said that is still “anemic” and “very weak.” Other signs, such as unemployment climbing to a 26-year high last month and stocks falling last week, also point to an economy that is rebounding more slowly than predicted.

Fears of a second global economic slump were fueled by HSBC Holdings plc CEO Michael Geoghegan, who forecast a W-shaped recovery in a Financial Times report.
