A major overhaul of Hong Kong’s compulsory pension system – the Mandatory Provident Fund (MPF) – could bring about savings of between HK$30 billion (US$3.9 billion) and HK$40 billion for millions of employees in the first 10 years after its launch in 2023, a government minister says.Secretary for Financial Services and the Treasury Christopher Hui Ching-yu disclosed the figures in a post on Sunday on his official blog, in which he gave an update on the progress of work on the e-MPF platform.
