• Regulatory Requirements of Banks and Arbitrage in the Post-Crisis Federal Funds Market

  Staff Working Paper 2022-48 Rodney J. Garratt, Sofia Priazhkina

  This paper explains the nature of interest rates in the U.S. federal funds market after the 2007-09 financial crisis. We build a model of the over-the-counter lending market that incorporates new aspects of the financial system: abundance of liquidity, different regulatory standards for banks, and arbitrage opportunities created by limited access to the facility granting interest on excess reserves.

  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.

  Project Jasper: Are Distributed Wholesale Payment Systems Feasible Yet?

  Financial System Review - June 2017 James Chapman, Rodney J. Garratt, Scott Hendry, Andrew McCormack, Wade McMahon

  This report describes a joint endeavour between public and private sectors to explore a wholesale payment system based on distributed ledger technology (DLT). They find that a stand-alone DLT system is unlikely to be as beneficial as a centralized payment system in terms of core operating costs; however, it could increase financial system efficiency as a result of integration with the broader financial market infrastructure.
