Binance has its own stablecoin (BUSD) so it doesn't really need another one. However, everything will depend on the popularity of CBDC. If it turns out that users prefer to use CBDC, Binance will also adopt this stablecoin to be a more competitive exchange.
Binance has branches in many countries, and remember that binance gets some
regulatory pressure simultaneously last July. CBDC legal strength is greater than stable coins made private institutions. Listing CBDC is not on the basis of its popularity, even the local governments can prohibit any exchanges that have been operated on their countries that listed any stable coins other than CBDC.
