China's A-share market saw its biggest IPO since 2010 on Tuesday. The Postal Savings Bank of China, the country's largest banking institution, was listed on the Shanghai Stock Exchange and saw a rise of nearly two percent from its initial public offering price. The bank raised at least 28 billion yuan or four billion U.S. dollars on its first trading day. Established in 2007, the bank was listed in Hong Kong in 2016 and is now one of the six leading state-owned banks in China, which are all listed, both on the A-shares and H-shares markets.
