Mainland listings will continue to boost Hong Kong's capital markets despite the re-opening of mainland bourses, the South China Morning Post reported. The total amount raised by mainland companies in Hong Kong is expected to exceed last year's record US$23 billion, 75% of the US$30 billion of equity capital raised in all of last year, according to Dealogic. By last Friday, mainland companies had raised US$14.9 billion in Hong Kong compared with US$6 billion at this point last year, driven by Bank of China's US$11 billion offering last month, the world's fourth-largest ever. It is expected to be topped this year when Industrial and Commercial Bank of China, the mainland's largest lender, sells shares worth as much as US$15 billion. Other deals headed to market this year include a US$2 billion offering by China Merchants Bank, a US$1 billion offering from China National Coal, the mainland's second-largest coal miner, and US$2 billion from SAIC Motor, the second biggest carmaker.
