The film will tell the fictional story of Lee Gates, a television personality who is also a Wall Street honcho thanks to years of insider trading tips.
Gates finds himself in hot water when a viewer who loses his entire fortune thanks to a bad tip holds him hostage on live television.
Shooting on Money Monster is due to begin in early 2013.
This is not Foster's first time behind the camera - she has directed three movies, including Home for the Holidays and The Beaver.
It was recently revealed that she is also attached to direct mob drama Angie's Body for Showtime.
