I think originally it was American, a corruption (no pun intended) of graft (= 'cheat, swindle'), but I think it's become almost universally known now, thanks in part to classic films such as The Sting.
There was also an excellent 1990 film called The Grifters with a cast that included Anjelica Huston and Annette Bening, and the word was often used in the long-running BBC comedy/crime series Hustle .
