This note discusses insights from historical launches of new payment methods and related laboratory experiments on the potential adoption and use of a central bank digital currency in the Canadian context.

Security is an important element in ensuring public confidence in a central bank digital currency (CBDC). This note highlights the required security properties of a CBDC system and the challenges encountered with existing solutions, should the Bank of Canada choose to issue one.

If the Bank of Canada issues a central bank digital currency, the technology should be designed for universal access.

Privacy is a key aspect of a potential central bank digital currency system. We outline different technical choices to enact various privacy models while complying with the appropriate regulations. We develop a framework to evaluate privacy models and list key risks and trade-offs in privacy design.

In this paper, we discuss whether the ability of individuals to convert commercial bank money (i.e., bank deposits) into central bank money is fundamentally important for the monetary system.

Using a two-stage model, we study the determinants of Canadian consumers’ choices of payment method at the point of sale. We estimate consumer preferences and adoption costs for various combinations of payment methods. We analyze how introducing a central bank digital currency would affect the market equilibrium.

In this note, we highlight a range of technical options and considerations in designing a contingent system for a central bank digital currency (CBDC) in Canada and explore how these options achieve stated public policy goals.

In an increasingly digitalized world, issuers of private digital currency can weaken central banks’ ability to stabilize the economy. By continuing to make central bank money attractive as a payment instrument in a digital world, a central bank digital currency (CDBC) could help to maintain a country’s monetary sovereignty.

Improving the conduct of monetary policy is unlikely to be the main motivation for central banks to issue a central bank digital currency (CBDC). While some argue that a CBDC could allow more complex transfer schemes or the ability to break below the zero lower bound, we find these benefits might be small or difficult to realize in practice.

Cash use for payments has been steadily decreasing in many countries, including Canada and Sweden. This might suggest an evolution toward a cashless society. But in Canada, cash in circulation relative to GDP has been stable for decades and has even increased in recent years. By contrast, the cash-to-GDP ratio in Sweden has been falling steadily. What has caused this difference? Are there lessons to be learned from comparing the Canadian and Swedish experiences?
