According to CoinMeta, the European Central Bank (ECB) and the Eurosystem, which consists of the central banks of the 27 EU countries, stated in their consultation opinions regarding the EU's 'Regulation on the Markets in Crypto Assets' that stablecoin issuers should not be compelled to hold a minimum proportion of their reserve assets in banks. This is because fluctuations in the stablecoin market could lead to a rapid outflow of such deposits, increasing the risks for banks. The central banks recommend amending the regulations to require that a minimum proportion of token reserves be allocated to short-term assets that mature within one to five working days, in order to ensure the liquidity of these reserves. Furthermore, it is noted that some crypto enterprises that do not comply with the regulations are still able to access EU customers, posing significant challenges to regulatory enforcement and raising concerns regarding investor protection.
