Critical
Perfect Exchange received relatively positive scores of 6.1/10 stars from the Internet Movie Database and 6.8/10 stars from Douban. Kenneth Brorsson of So Good Reviews gave the film a positive review and writes "It helps that a performer like Tony Leung is very game and while Andy Lau is the cool presence in addition to a character rarely being in danger, he's the lesser part of the double act. It just doesn't seem like a fit to have Lau this time around in such a jarring Wong Jing film that mixes the crazy, the silly, Lau going into prison on a rape charge and various, jarring pieces of violence scattered throughout. But it's bearable and actually funny in parts so therefore great success coming from Wong Jing."

Box office
The film grossed HK$27,912,327 at the Hong Kong box office during its theatrical run from 30 September to 20 October 1993 in Hong Kong.
