Since its launch eight years ago, the total value of deals sealed via the Stock Connect between the Hong Kong Special Administrative Region and the Chinese mainland has reached $16.7 trillion, according to Hong Kong Exchanges and Clearing, which runs the city s bourse.
As of November 30, the turnover from northbound trading had hit 89.4 trillion yuan $12.8 trillion, resulting in a net capital inflow of 1.7 trillion yuan into the mainland's equity market.
Equity investors on the mainland contributed $30.4 trillion $3.9 trillion for southbound trading, bringing net capital inflow of HK $2.6 trillion into the SAR.
The Hong Kong-Shanghai Stock Connect, which was rolled out in 2014, and the Hong Kong-Shenzhen Stock Connect, followed two years later, allow for two-way cross-boundary stock investments. They have become a major conduit for global and mainland investors to get exposure to each other's markets.
