Novating a single asset class to a central counterparty (CCP) in an over-the-counter derivatives trading network impacts both the mean and variance of total net exposures between counterparties. When a small number of dealers trade in a relatively large number of asset classes, central clearing...

Initial coin offerings (ICOs) are a new mode of financing start-ups that saw an explosion in popularity in 2017 but declined in popularity in the second half of 2018 as regulatory pressure, instances of fraud and reports of poor performance began to undermine their reputation. We examine whether...

We explore the implications of introducing an interest-bearing central bank digital currency (CBDC) through commercial banks that differ in size. Banks of heterogeneous sizes offer different convenience properties to depositors, which the CBDC adopts. The large bank gives depositors a higher...

An individual bank can put the whole banking system at risk if its losses in response to shocks push losses for the system as a whole above a critical threshold. We determine the contribution of banks to this systemic risk using a generalisation of the Shapley value; a concept originating in...

We re-examine the canonical question of Myerson and Satterthwaite (1983) whether two privately-informed parties, a buyer and a seller, can trade an indivisible good efficiently. We relax their assumption that utilities are quasi-linear; our main assumption instead is that the traded good is...

Private tokenised monies that circulate as bearer instruments, like stablecoins, may entail departures in their relative exchange values away from par in violation of the “singleness of money”. In contrast, tokenised deposits that do not circulate as bearer instruments but rather settle in...

This paper uses reinforcement learning (RL) to approximate the policy rules of banks participating in a high-value payments system. The objective of the agents is to learn a policy function for the choice of amount of liquidity provided to the system at the beginning of the day. Individual...

Dealers, who strategically supply liquidity to traders, are subject to both liquidity and adverse selection costs. While liquidity costs can be mitigated through inter-dealer trading, individual dealers' private motives to acquire information compromise inter-dealer market liquidity. Post-trade...

Privacy is a feature inherent to the use of cash for payments. With steadily increasing market shares of commercial digital payments platforms, privacy in payments may no longer be attainable in the future. In this paper, we explore the potential welfare impact of reductions in privacy in...

We assess how the cost structure of cryptocurrency mining affects the response of miners to exchange rate fluctuations and the immutability of cryptocurrency ledgers that rely on proof-of-work. We show that the amount of mining power supplied to currencies that rely on specialized hardware, such...
