Both the Asian financial hubs have made insufficient reforms to their corporate secrecy regimes, according to the London-based TJN, which campaigns for greater transparency in finance. Singapore's ranking moved to fourth from the fifth place it held in the organisation's previous index in 2013, when Hong Kong placed third.
"Singapore, in fourth place, poses many of the same threats that Hong Kong does: a lack of serious reforms to its corporate secrecy regime; a lack of interest in creating country-by- country reporting or in creating public registries of beneficial ownership," the TJN said.
The two cities each account for about 4 per cent of the global market for offshore financial services, the organisation said. The hubs are well exposed to offshore flows because of rising assets under management and their status as regional financial hubs, according to the TJN.
The US was ranked third for its refusal to take part in a global system for exchanging bank data created by the Organisation for Economic Cooperation and Development.
