According to a press release, the upgraded Stock Connect, dubbed Synapse, will incorporate smart contracts to help execute post-trade workflows and reduce settlement risk.

Synapse is able to simultaneously create settlement instructions for all parties along the settlement chain, facilitating concurrent processing, while also providing near-instantaneous status updates to all parties involved in the trade, a technical pamphlet explains, which is important when connecting traders in two different markets.

The average daily turnover of the Stock Connect totaled $15.302 billion (109.3 billion RMB) in the first half of 2023, up 5 percent from a year earlier, and a 50 percent increase from 2020 levels.

In Australia, the ASX has been advised to adopt blockchain technology to replace its settlement system called CHESS, the Australian Financial Review reported last year.

Synapse is scheduled to launch in Hong Kong on October 9.
