• On the Fragility of DeFi Lending

  Staff Working Paper 2023-14 Jonathan Chiu, Emre Ozdenoren, Kathy Yuan, Shengxing Zhang

  We develop a dynamic model to capture key features of decentralized finance lending. We identify a price-liquidity feedback: the market outcome in any given period depends on agents' expectations about lending activities in future periods, with higher future price expectations leading to more lending and higher prices in that period.

• Central Bank Digital Currencies and Banking: Literature Review and New Questions

  Staff Discussion Paper 2023-4 James Chapman, Jonathan Chiu, Mohammad Davoodalhosseini, Janet Hua Jiang, Francisco Rivadeneyra, Yu Zhu

  We review the nascent but fast-growing literature on central bank digital currencies (CBDCs), focusing on their potential impacts on private banks. We evaluate these impacts in three areas of traditional banking: payments, lending and liquidity and maturity transformation. We also take a broader look at CBDCs and highlight two promising directions for future research.

• The 2021–22 Merchant Acceptance Survey Pilot Study

  Staff Discussion Paper 2023-1 Angelika Welte, Joy Wu

  The rise in digital payment innovations has spurred a discussion about the future of cash at the point of sale. The Bank conducted the 2021–22 Merchant Acceptance Survey Pilot Study to study trends in merchant cash acceptance and monitor conditions for the potential issuance of a central bank digital currency.

• Improving the Efficiency of Payments Systems Using Quantum Computing

  Staff Working Paper 2022-53 Christopher McMahon, Donald McGillivray, Ajit Desai, Francisco Rivadeneyra, Jean-Paul Lam, Thomas Lo, Danica Marsden, Vladimir Skavysh

  We develop an algorithm and run it on a hybrid quantum annealing solver to find an ordering of payments that reduces the amount of system liquidity necessary without substantially increasing payment delays.

• Potential benefits and key risks of fiat-referenced cryptoassets

  Staff Analytical Note 2022-20 Hugh Ding, Natasha Khan, Bena Lands, Cameron MacDonald, Laura Zhao

  Cryptoassets that reference a national currency (commonly known as stablecoins) aim to peg their value to the reference currency and typically use a reserve of traditional financial assets to maintain the peg. The market value of these fiat-referenced cryptoassets has grown more than thirtyfold between early 2020 and mid-2022. We explore some of their potential benefits and key risks.

• The Relative Benefits and Risks of Stablecoins as a Means of Payment: A Case Study Perspective

  Staff Discussion Paper 2022-21 Annetta Ho, Sriram Darbha, Yuliya Gorelkina, Alejandro García

  Our paper contributes to the discussion about the utility of stablecoins for retail payments through an objective, evidence-based approach that compares stablecoins with traditional retail payment methods. The paper also provides insights that could be useful in the design of central bank digital currencies.

• Stablecoins and Their Risks to Financial Stability

  Staff Discussion Paper 2022-20 Cameron MacDonald, Laura Zhao

  What risks could stablecoins pose to the financial system? We argue that the stabilization mechanisms of stablecoins give rise to the risk of confidence runs, which can propagate to broader cryptoasset markets and the traditional financial sector. We also argue that stablecoins can contribute to financial stability risks by facilitating the buildup of leverage and liquidity mismatch in decentralized finance. Such risks cannot be addressed by ensuring the price stability of stablecoins alone. Finally, we explore the potential implications of stablecoins for the current system of bank-intermediated credit and for monetary policy.

• Private Digital Cryptoassets as Investment? Bitcoin Ownership and Use in Canada, 2016-2021

  Staff Working Paper 2022-44 Daniela Balutel, Walter Engert, Christopher Henry, Kim Huynh, Marcel Voia

  We report on the dynamics of Bitcoin awareness and ownership from 2016 to 2021, using the Bank of Canada's Bitcoin Omnibus Surveys (BTCOS). Our analysis also helps understand Bitcoin owners who adopted during the COVID-19 and how they differ from long-term owners.

• Grasping De(centralized) Fi(nance) Through the Lens of Economic Theory

  Staff Working Paper 2022-43 Jonathan Chiu, Charles M. Kahn, Thorsten Koeppl

  We analyze the value proposition and limitations of decentralized finance (DeFi). Based on a distributed ledger and smart contracts, DeFi can guarantee the execution of financial contracts, potentially lowering the costs of intermediation and improving financial inclusion.
