According to Digital Asset, the Bank of Korea will require virtual asset transfer service providers to submit monthly reports to the foreign exchange information system starting December 2. The reports must cover end-of-month holdings of users who have made cross-border crypto asset transfers to overseas exchanges, personal wallets, or other destinations since July 19, 2024—even if no cross-border transactions occurred in the reporting month. Submissions include holding amounts, South Korean won-converted balances, and total monthly cross-border inflows and outflows. Dormant accounts, delisted assets, and staked assets are also within scope, with reports due by 17:30 on the 10th of the following month. It remains undecided whether cross-border transfer records prior to the system’s implementation will need to be retroactively submitted.

According to a report by the South China Morning Post, HSBC will roll out its Hong Kong dollar stablecoin, HSBC RedCoin, in phases starting October 23, with the first batch targeting over 3.3 million users of Hong Kong’s payment app PayMe. Initially, RedCoin will only be accessible via PayMe and HSBC Hong Kong’s mobile banking app, supporting peer-to-peer transfers between PayMe users and payments to merchants. Users can activate their RedCoin wallets after updating the apps, with no minimum balance requirement or additional account needed. Lawrence Li, head of HSBC PayMe, said the first phase focuses on ensuring service stability, avoiding adding operational burdens for users, and building trust. HSBC previously conducted an internal pilot involving nearly 100 employees to test the full user flow and system integration. The bank plans to fully integrate RedCoin into its Hong Kong mobile banking app by the end of the year, and support users in subscribing to tokenized asset products including money market funds, with a minimum investment of HK$100. John O’Neill, managing director of digital assets and currency at HSBC, noted that stablecoins enable instant settlement for tokenized funds, reducing the time required for traditional investment settlements and lowering investment barriers. The launch comes as Hong Kong accelerates the development of its digital asset market.
