CBDC in the Market for Payments at the Point of Sale: Equilibrium Impact and Incumbent Responses Staff Working Paper 2024-52 Walter Engert, Oleksandr Shcherbakov, André Stenzel We simulate introducing a central bank digital currency (CBDC) and consider consumer adoption, merchant acceptance and usage at the point of sale. Modest adoption frictions significantly inhibit CBDC market penetration along all three dimensions. Incumbent responses to restore pre-CBDC market shares are moderate to small and further reduce the impact of a CBDC.

The impact of a central bank digital currency on payments at the point of sale Staff Analytical Note 2024-27 Walter Engert, Oleksandr Shcherbakov, André Stenzel We simulate the impact of a central bank digital currency (CBDC) on consumer adoption, merchant acceptance and use of different payment methods. Modest frictions that deter consumer adoption of a CBDC inhibit its market penetration. Minor pricing responses by financial institutions and payment service providers further reduce the impact of a CBDC.

The Consumer Value Proposition for a Hypothetical Digital Canadian Dollar Staff Discussion Paper 2024-16 Martine Warren, Bill Laur, Ted Garanzotis, Sebastian Hernandez We explore the consumer value proposition of a hypothetical Digital Canadian Dollar, adoption considerations and the users who would benefit most from this potential new payment method. We employ a design-thinking consultation methodology, allowing participants to interact with research prototypes of increasing complexity to reveal user preferences, constraints and adoption influences.

The Role of Public Money in the Digital Age Staff Discussion Paper 2024-11 Francisco Rivadeneyra, Scott Hendry, Alejandro García A well-functioning monetary system is characterized by public and private forms of money that exchange at par as value flows freely between them. A relevant retail public money—whether in the form of cash, a central bank digital currency or both—is a necessary component of such a monetary system.

Untapped Potential: Mobile Device Ownership and Mobile Payments in Canada Staff Working Paper 2024-25 Marie-Hélène Felt, Angelika Welte, Katrina Talavera We present a two-stage model of mobile phone and mobile payment usage that controls for selectivity. This reveals unobserved factors that work against having a mobile phone and toward mobile paying. Therefore, people who are unable to acquire or choose not to own a mobile device might have unmet payment needs.

Analysis of DeFi Oracles Staff Discussion Paper 2024-10 Xun Deng, Sidi Mohamed Beillahi, Cyrus Minwalla, Han Du, Andreas Veneris, Fan Long Oracles are constructs used in decentralized finance to price assets relative to each other. However, oracles contain defects that could lead to manipulation attacks. Such attacks exploit pricing models embedded within oracles to defraud creators and users. We automatically verify defects, which if mitigated, improves the security of digital currency.

Finding a Needle in a Haystack: A Machine Learning Framework for Anomaly Detection in Payment Systems Staff Working Paper 2024-15 Ajit Desai, Anneke Kosse, Jacob Sharples Our layered machine learning framework can enhance real-time transaction monitoring in high-value payment systems, which are a central piece of a country’s financial infrastructure. When tested on data from Canadian payment systems, it demonstrated potential for accurately identifying anomalous transactions. This framework could help improve cyber and operational resilience of payment systems.

CBDC: Banking and Anonymity Staff Working Paper 2024-9 Yuteng Cheng, Ryuichiro Izumi We examine the optimal amount of user anonymity in a central bank digital currency in the context of bank lending. Anonymity, defined as the lender’s inability to discern an entrepreneur’s actions that enable fund diversion, influences the choice of payment instrument due to its impact on a bank’s lending decisions.
