• From LVTS to Lynx: Quantitative Assessment of Payment System Transition

  Staff Working Paper 2023-24 Ajit Desai, Zhentong Lu, Hiru Rodrigo, Jacob Sharples, Phoebe Tian, Nellie Zhang

  We quantitatively assess the changes in participants’ payment behaviour from modernizing Canada's high-value payments system to Lynx. Our analysis suggests that Lynx's liquidity-saving mechanism encourages liquidity pooling and early payments submission, resulting in improved efficiency for participants but with slightly increased payment delays.

• Simulating Intraday Transactions in the Canadian Retail Batch System

  Staff Working Paper 2023-1 Nellie Zhang

  This paper proposes a unique approach to simulate intraday transactions in the Canadian retail payments batch system when such transactions are unobtainable. The simulation procedure has potential for helping with data-deficient problems where only high-level aggregate information is available.

• Liquidity Usage and Payment Delay Estimates of the New Canadian High Value Payments System

  Staff Discussion Paper 2020-9 Francisco Rivadeneyra, Nellie Zhang

  As part of modernizing its core payments infrastructure, Canada will replace the Large Value Transfer System (LVTS) with a new Real-Time Gross Settlement (RTGS) system called Lynx. An important question for policy-makers is how Lynx should be designed.

• Changes in Payment Timing in Canada’s Large Value Transfer System

  Staff Working Paper 2015-20 Nellie Zhang

  This paper uncovers trends in payment timing in Canada’s Large Value Transfer System (LVTS) from 2003 to 2011. Descriptive analysis shows that LVTS payment activity has not been peaking in the late afternoon since 2008, and the improvement was most significant in 2009.

• Losses from Simulated Defaults in Canada's Large Value Transfer System

  Staff Discussion Paper 2010-14 Nellie Zhang, Tom Hossfeld

  The Large Value Transfer System (LVTS) loss-sharing mechanism was designed to ensure that, in the event of a one-participant default, the collateral pledged by direct members of the system would be sufficient to cover the largest possible net debit position of a defaulting participant. However, the situation may not hold if the indirect effects of the defaults are taken into consideration, or if two participants default during the same payment cycle.

• Estimating the Structure of the Payment Network in the LVTS: An Application of Estimating Communities in Network Data

  Staff Working Paper 2010-13 James Chapman, Nellie Zhang

  In the Canadian large value payment system an important goal is to understand how liquidity is transferred through the system and hence how efficient the system is in settling payments. Understanding the structure of the underlying network of relationships between participants in the payment system is a crucial step in achieving the goal.
