The European Central Bank said that EU banks should start setting limits on Bitcoin holdings before global standards developed by the Basel Committee on Banking Supervision (BCBS) come into effect. The ECB said that although cryptocurrencies have not yet had a significant impact on EU banks, banks should treat these assets as risky assets and limit their holdings immediately. The ECB also said that the BCBS standard is not yet legally binding in the EU, but if banks want to enter this market, they should comply with it and take into account the regulatory requirements in their business and capital planning.
