Recently Ben Fung from the Central Bank of Canada and Walter Engert from the office of the superintendent of Financial Institutions published a document about the pros and cons for issuing central bank digital currency (CBDC). And they consider that it is possible for Central Banks to issue cryptocurrency. But they think the benefits from it would vary depending on whether how developed is the economy in countries.
Also they identify three different supposed benefits to a central bank for issuing a digital currency: payments for consumers, financial inclusion and stability. it would easy online payments and entice smaller merchants to offer services over the internet. In other economies, it can be benefits in reducing costs for retail payments to consumers.
Then they think that digital money would give consumers a largely risk-free way to store value but the ease of leaving bank deposits for a fiat crypto could accelerate financial turmoil.
