Net Send Limits in the Lynx Payment System: Usage and Implications Staff discussion paper 2025-13 Virgilio B Pasin, Anna Wyllie We study how participants in the Lynx payment system use the net send limit (NSL) tool to control their intraday payment outflow levels. Our results show that participants typically adopt a “set it and forget it” approach to scheduling NSLs and sometimes have distinct intraday NSL adjustment behaviours.

Dynamic Consumer Cash Inventory Model Staff working paper 2025-22 Kim Huynh, Oleksandr Shcherbakov, André Stenzel We study consumer cash inventory behavior by developing a dynamic model of forward-looking consumers and estimating structural parameters of the model using detailed consumer survey data. Consumers facing holding and withdrawal costs solve a discrete-time continuous-control dynamic programming problem to optimally use cash at the point of sale.

2024 Methods-of-Payment Survey Report: Cash in an Era of Alternatives Staff discussion paper 2025-12 Marie-Hélène Felt, Anna Chernesky, Angelika Welte We present core findings from the 2024 Methods-of-Payment Survey, highlighting results from both the survey questionnaire and three-day shopping diary. Although cash holdings have increased in nominal terms, we find that cash usage remains unchanged since 2020. Mobile and other alternative payment methods continue to grow in importance.

Correcting Selection Bias in a Non-Probability Two-Phase Payment Survey Staff working paper 2025-17 Heng Chen, John Tsang We develop statistical inferences for a non-probability two-phase survey sample when relevant auxiliary information is available from a probability survey sample. The proposed method is assessed by simulation studies and used to analyze a non-probability two phase payment survey.

Incorporating Trip-Chaining to Measuring Canadians’ Access to Cash Staff working paper 2025-16 Heng Chen, Hongyu Xiao Our paper employs smartphone data to construct an improved cash access metric by accounting for both spatial agglomeration and households’ travel patterns. We find that incorporating trip-chaining into the travel metric could show that travel costs are from 15 to 25% less than not incorporating trip-chaining and that the biggest decrease is driven by rural residents.

A Retail CBDC Design for Basic Payments: Feasibility Study Staff discussion paper 2025-9 Sriram Darbha, Cyrus Minwalla, Rakesh Arora, Dinesh Shah We outline possible system architectures for an online retail central bank digital currency (CBDC) and identify one well-suited for basic payments. We analyze OpenCBDC 2PC, a representative system, finding such designs to be feasible, although some areas require further investigation. Our framing highlights other promising architectures for a retail CBDC.
