Global hedge fund assets are expected to hit $2.6 trillion (€2 trillion) by 2013—after bottoming out this year—reflecting a maturation of the industry and renewed investor interest, according to a study by the Bank of New York Mellon and Casey, Quirk & Associates.

Global hedge fund assets, which stand at $1.4 trillion, will decrease to $1 trillion this year. However, greater regulatory oversight will bring more transparency and a clearer market will drive assets to inflate.
