• 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.

• Endogenous Credibility and Wage-Price Spirals

  Staff Working Paper 2024-14 Olena Kostyshyna, Tolga Özden, Yang Zhang

  We quantitively assess the risks of a wage-price spiral occurring in Canada over history. We find the risk of a wage-price spiral increases when the inflation expectations become unanchored and the credibility of central banks declines.

• Parallel Tempering for DSGE Estimation

  Staff Working Paper 2024-13 Joshua Brault

  I develop a population-based Markov chain Monte Carlo algorithm known as parallel tempering to estimate dynamic stochastic general equilibrium models. Parallel tempering approximates the posterior distribution of interest using a family of Markov chains with tempered posteriors.

• Potential output in Canada: 2024 assessment

  Staff Analytical Note 2024-11 Tessa Devakos, Christopher Hajzler, Stephanie Houle, Craig Johnston, Antoine Poulin-Moore, Ron Rautu, Temel Taskin

  We expect that potential output in Canada will grow by 2.3% and 2.5% in 2023 and 2024, respectively, and average slightly below 1.7% by 2027 as population growth moderates. Relative to the April 2023 assessment, growth is revised up in 2024, with a larger contribution from trend labour input due to higher-than-anticipated population growth. We revise down our estimates of growth over 2025–26.

• Assessing global potential output growth: April 2024

  Staff Analytical Note 2024-10 Amor Aniss Benmoussa, Raheeb Dastagir, Eshini Ekanayake, Justin-Damien Guénette, Helen Lao, Jenna Rolland-Mills, Aidan Spencer, Lin Xiang

  This note presents the annual update of Bank of Canada staff estimates for growth in global potential output. These estimates serve as key inputs to the analysis supporting the April 2024 Monetary Policy Report.

• Assessing the US and Canadian neutral rates: 2024 update

  Staff Analytical Note 2024-9 Frida Adjalala, Felipe Alves, Hélène Desgagnés, Wei Dong, Dmitry Matveev, Laure Simon

  We assess both the US and Canadian nominal neutral rates to be in the range of 2.25% to 3.25%, somewhat higher than the range of 2.0% to 3.0% in 2023. The assessed range is back to the level it was at in April 2019.

• Benchmarks for assessing labour market health: 2024 update

  Staff Analytical Note 2024-8 Erik Ens, Alexander Lam, Kurt See, Gabriela Galassi

  We assess the health of the Canadian labour market. We find that it has seen gradual but material easing since 2023, amid some signs of structural changes.

• The Neutral Interest Rate: Past, Present and Future

  Staff Discussion Paper 2024-3 Matteo Cacciatore, Bruno Feunou, Galip Kemal Ozhan

  The decline in safe real interest rates over the past three decades has reignited discussions on the neutral real interest rate, known as R*. We address the determinants and estimation methods of R*, as well as the factors influencing its decline and its future trajectory.

• U.S. Macroeconomic News and Low-Frequency Changes in Small Open Economies’ Bond Yields

  Staff Working Paper 2024-12 Bingxin Ann Xing, Bruno Feunou, Morvan Nongni-Donfack, Rodrigo Sekkel

  Using two complementary approaches, we investigate the importance of U.S. macroeconomic news in driving low-frequency fluctuations in the term structure of interest rates in Canada, Sweden and the United Kingdom. We find that U.S. macroeconomic news is particularly important to explain changes in the expectation components of the nominal, real and break-even inflation rates of small open economies.

• Liquidity risks at Canadian life insurance companies

  Staff Analytical Note 2024-7 Patrick Aldridge, Stephane Gignac, Rishi Vala, Adrian Walton

  We examine how life insurers manage liquidity risks created by their business model. We find that Canadian life insurers did not face significant liquidity draws and continued their usual investment behaviour during the COVID-19 crisis and as interest rates increased in 2022.
