• 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.

• A central bank digital currency for offline payments

  Staff Analytical Note 2023-2 Cyrus Minwalla, John Miedema, Sebastian Hernandez, Alexandra Sutton-Lalani

  Offline functionality is a key consideration for a potential CBDC. We describe the different types of offline functionality based on their duration outside of network connection—either intermittent (for short periods) or extended (for longer periods). We discuss the advantages and drawbacks of each and consider implications for end-user devices, system resilience and universal accessibility.

• Archetypes for a retail CBDC

  Staff Analytical Note 2022-14 Sriram Darbha

  A variety of technology designs could support retail central bank digital currency (CBDC) systems. We develop five archetypes of CBDC systems, outline their characteristics and discuss their trade-offs. This work serves as a framework to analyze and compare different designs, independent of vendor, platform and implementation.

• How does the Bank of Canada’s balance sheet impact the banking system?

  Staff Analytical Note 2022-12 Daniel Bolduc-Zuluaga, Brad Howell, Grahame Johnson

  We examine how changes in the Bank of Canada’s balance sheet impact the banking system. Quantitative easing contributed to an increase in the size of the banking system’s balance sheet and an improvement in bank liquidity coverage ratios. Quantitative tightening is expected to partially reverse these impacts. The banking system will have to adjust its liquidity management strategy in response.

• Financial Intermediaries and the Macroeconomy: Evidence from a High-Frequency Identification

  Staff Working Paper 2022-24 Pablo Ottonello, Wenting Song

  We provide empirical evidence of effects to the aggregate economy from surprises about financial intermediaries’ net worth based on a high-frequency identification strategy. We estimate that news of a 1% decline in intermediaries’ net worth leads to a 0.2%–0.4% decrease in the market value of nonfinancial firms.

• Behaviour in the Canadian large-value payment system: COVID-19 vs. the global financial crisis

  Staff Analytical Note 2021-7 Alexander Chaudhry, Anneke Kosse, Karen Sondergard

  Unlike the 2008–09 global financial crisis, the onset of the COVID-19 crisis did not raise stress levels in Canada’s Large Value Transfer System. Swift changes to the Bank of Canada’s collateral policy and its large-scale asset purchase programs likely eased liquidity pressures in the system.

• Survival Analysis of Bank Note Circulation: Fitness, Network Structure and Machine Learning

  Staff Working Paper 2020-33 Diego Rojas, Juan Estrada, Kim Huynh, David T. Jacho-Chávez

  Using the Bank of Canada's Currency Information Management Strategy, we analyze the network structure traced by a bank note’s travel in circulation and find that the denomination of the bank note is important in our potential understanding of the demand and use of cash.
