In its annual economic report, the BIS further warms to the idea that CBDC is a key part of central banks’ response to financial innovation.

• Central banks play a pivotal role in maintaining the safety and integrity of the payment system. They provide the solid foundation by acting as guardians of the stability of money and payments. The pandemic and resulting strain on economic activity around the world have confirmed the importance of central banks in payments.
• Digital innovation is radically reshaping the provision of payment services. Central banks are embracing this innovation. They promote interoperability, support competition and innovation, and operate public infrastructures – all essential for easily accessible, low-cost and high-quality payment services.
• Central banks, as critical as ever in the digital era, can themselves innovate. In particular, central bank digital currencies (CBDCs) can foster competition among private sector intermediaries, set high standards for safety and risk management, and serve as a basis for sound innovation in payments.
