Deep Tide TechFlow News: On March 17, according to reports from Hong Kong media Hong Kong Economic Times, Citigroup stated in an analysis report that, referencing the experience of mainland payment institutions, the user balances in mainland payment institutions are roughly equivalent to about 20% of China's circulating cash, 2.5% of demand and savings deposits, and 0.8% of all deposits. It is estimated that the Hong Kong stablecoin market could reach a size of $16 billion USD (approximately HK$124.8 billion), with a fluctuation range of ±$8 billion USD. If the total money supply continues to grow, combined with increased demand for Hong Kong stablecoins from overseas users or a surge in on-chain activity, this scale could further expand, benefiting issuers, trading platforms, and payment companies.
