Some of the biggest banks in Singapore are in talks about setting up a system for sharing information on prospective clients, in an effort to combat money laundering. DBS Group, OCBC and United Overseas Bank are exploring the possibility of a countrywide model for anti-money laundering and enhanced client knowledge. A senior official of OCBC said the bank believes the new model will bring significant control and operational efficiency benefits to the industry and Singapore. The model under review would see the three banks pool data at a newly-created registry. The banks would use the information when deciding whether to approve applications for new accounts. There is no timeline on when the registry would be set up, said the people. The plan may be expanded to international banks in Singapore if a pilot proves successful, they said.
