Postal Savings Bank of China is looking to raise US$8 billion by listing its shares in Hong Kong, the BBC reports. The initial public offering will be the biggest share sale in the world this year and the second largest ever by a Chinese company (after Alibaba). The retail customer-focused PSBC is China's fifth largest lender by asset size but has the largest number of branches. US bank Wells Fargo, which has been fined US$185 million for questionable sales practices, has told employees to stop cross-selling products, the Wall Street Journal reports. Practices that attracted the fine include employees setting up accounts without customers' knowledge and charging fees on them. The bank has attracted widespread criticism in the US after its settlement with the regulator was made public last week.
