Postal Savings Bank of China Corp. is gearing up for what could be the biggest initial public offering in the world this year—at more than $7 billion—even as the market for new listings is in its slowest period since the global financial crisis, The Wall Street Journal reports. The Chinese state lender is planning to file its listing application with the Hong Kong stock exchange in the next two weeks, according to people familiar with the matter. If the process goes smoothly, the bank could list shares as soon as September or October, they said. The biggest IPO globally this year was in May, when Danish utility Dong Energy raised $2.61 billion.
