According to online reports, Xu Zhengyu, Secretary for Financial Affairs and the Treasury of the Hong Kong Special Administrative Region, said in an interview at the Lujiazui Forum that the use of stablecoins is to return to the essence of finance and effectively solve the pain points in economic activities, rather than simply pursuing the application of technology or just to achieve interconnection. The supervision of stablecoins issuance is similar to the supervision of similar financial institutions. Specifically, the issuer itself needs to have capital; Second, if the issuer exchanges money with the holder of the stablecoin, the reserve must not be lower than the value of the currency behind the unredeemed stablecoin at any time; third, if the holder of the stablecoin wants to exchange currency with the issuer, it must be completed within one trading day, one business day or one working day.
