The Jersey Competition Regulatory Authority (JCRA) is considering changes to the competition law.
The watchdog has announced that it will review how it deals with mergers and acquisitions.
Under the current law certain mergers or acquisitions between companies need prior approval.
John Curran, executive director, said there were questions about whether limited resources could be better targeted.
He said: "We are undertaking a full review to see how we can ensure Jersey consumers are protected while focusing on mergers that have more obvious direct impacts on the Jersey economy."
