Central bank digital currencies (CBDCs) are digital versions of fiat currencies issued and backed by central banks. They can potentially be used as an alternative to physical cash, as well as a means for conducting digital transactions and facilitating cross-border payments.

There are several ways in which CBDCs could potentially help the financial system:

1. Increased accessibility: CBDCs could potentially make it easier for people to access financial services, especially in areas where access to physical cash or bank branches is limited.
2. Improved efficiency: CBDCs could potentially increase the efficiency of financial transactions, as they can be conducted digitally and with faster processing times than traditional payment methods.
3. Enhanced financial stability: CBDCs could potentially enhance financial stability by providing an alternative to traditional banks and payment systems, which could reduce the risk of a financial crisis caused by a failure in these systems.
4. Increased competition: CBDCs could potentially increase competition in the financial sector by providing a new means for conducting transactions and attracting customers.

It’s important to note that CBDCs are still in the early stages of development, and their potential impact on the financial system will depend on how they are implemented and used.
