A surge in banks' liquidity needs increases settlement costs that could burden the functioning of the real economy through its impact on banks' lending behavior. A liquidity-saving mechanism (LSM) can help reduce banks' liquidity needs, but it could also affect banks' strategic behavior. To...

We use agent-based modelling to build a digital twin of the retail payment system, where heterogeneous consumers and merchants interact, learn, and adapt as they meet and use different monies and payment instruments. As we introduce an rCBDC, the model simulates its adoption. We calibrate this...

The success of alternative payment systems has led to discussion of various proposals to replace money with a new technology-based system, though many lack a clear idea of what exactly is the "money" they seek to replace. We begin by presenting the explanation of money's role in the economy...

Canada currently has two core payment systems for processing funds transfers between financial institutions: the Large Value Transfer System (LVTS) and the Automated Clearing Settlement System (ACSS). These systems will be replaced over the next years by three new systems: Lynx, the Settlement...

An anonymous credential mechanism is a set of protocols that allows users to obtain credentials from an organization and demonstrate ownership of these credentials without compromising users' privacy. In this work, we construct the first secret-free and quantum-safe credential mechanism. The...

We use block level data from the Bitcoin blockchain to estimate the impact of congestion and the USD price on average fee rates. The introduction and adoption of the Segwit protocol allows us to identify an aggregate demand curve for bitcoin transactions. We find that Segwit has reduced fee...

In this paper, we develop a discrete choice framework to quantify the economic benefits of payments modernization in Canada. Focusing on Canada's large-value transfer system (LVTS), we first estimate participants' preferences for liquidity cost, payment safety and the network effect by...

Canada is in the midst of developing three new core payment systems: Lynx, Settlement Optimization Engine (SOE) and Real-Time Rail (RTR). Lynx and SOE will replace the current Large Value Transfer System (LVTS) and Automated Clearing Settlement System (ACSS), whereas RTR will be a new...

The U.S. payments industry is in the process of developing ubiquitous, safe, faster electronic solutions for making a broad variety of business and personal payments. How this market for faster payments will evolve will be shaped by a range of economic forces, such as economies of scale and...

Digital payments and decentralized systems enable the creation of new financial products and services for users. One core challenge in digital payments is the need to protect users from fraud and abuse while retaining privacy in individual transactions. We propose a pseudonymous credential...
