Swiss bank UBS is banning its wealth management advisors from making business trips abroad to see foreign clients, a spokeswoman said yesterday. "I can confirm there is a travel ban for client-facing wealth management staff," UBS spokeswoman Eveline Mueller said. "We are currently conducting a comprehensive review of the policy and compliance framework in international wealth management," she added. Swiss media reported that about 1,000 of the bank's advisors were ordered in the past week to rely on email or telephone contacts with clients abroad. Mueller said the suspension would remain in place at least while the review of the "complex international regulatory environment" was underway. She declined to give further details. The review is understood to be international in scope.
