Central bank digital currencies: Reordering international monetary relations

Bretton Woods Committee blog post to the Bretton Woods@75 initiative

27 April 2019

Financial technology seems set to have a major impact on monetary relations. Several central banks are contemplating to offer central bank issued digital currencies (CBDC) as a medium of exchange for blockchain-enabled or token-based financial ecosystems. CBDC offers properties that could make the use of central bank money significantly easier in particular in cross-border but also off-shore transactions. It could transform the attractiveness of using CBDC relative to conventional currencies and thus alter the propensity to hold central bank money by non-residents. CBDC may therefore help address one the long held grievances about the international monetary system, namely the dependence on a very narrow set of currencies to conduct and settle international transactions and contribute to needed diversification in the international monetary system.


Tokenised SDR

UBS and RBWC Conference-Managing the soft landing of the global economy

Washington, D.C., 12 April 2019

[...] I will focus on an idea that was advanced by IMF Managing Director Christine Lagarde in 2017, namely to offer a digital SDR. Yesterday, at the IMF Seminar Money and Payments in the Digital Age, Lagarde asked if a digital SDR would be possible and one discussant responded that it could become functional within 12 to 24 months. At Accenture, I'm working on a number of projects and proposals that involve digitalising or tokenising central bank money. Hence, a tokenised SDR seems very much in line with an incipient new openness to give considerations to tokenising national currencies. But given the difficulties of amending the existing SDR, a new approach is needed. [...]

Are social networks optimum currency areas?

7 April 2019

The recent emergence of private digital currencies, like bitcoin, has been met with considerable criticism. Yet, recent rumours that a large social network may issue a digital currency seem to affirm that new types of currencies are in demand. A social network digital coin could propel the notion of private currencies to new levels. Economic theory seems supportive of the idea. Adoption of a social network coin would rest in large part on whether a social network would constitute an optimum currency area. If so, it could change the very architecture of money. [...]

Central bank digital currencies and a new currency architecture

LSE Institute of Global Affairs and Financial Markets Group Conference—Financial resilience and systemic risk

London, 31 January 2019

[...] In my brief remarks, I shall first highlight the case for new currencies. I shall then focus on blockchain-enabled digital currencies issued by central banks. I consider blockchain-based technologies to offer new properties critical to ensuring central bank currencies remain future-proof while laying the foundations for a new currency architecture. [...]

New architecture for payments systems

OMFIF Bulletin January 2019

London, 17 January 2018 with John Velissarios

Distributed ledger technology has made signifi cant advances over recent years, affi rming arguments that it is now beginning to challenge existing payments systems. DLT addresses ineffi ciencies and resiliency while allowing interoperability with existing and future payments systems. The case to implement this technology is among the strongest in cross-border payments, post-trade clearing and securities settlement. [...]

Financial innovation and the international monetary system

Bali and London, 14 October 2018

The impact of financial innovation on the functioning of the international economy has become an integral part of the multilateral policy agenda. The announcement at the IMF-World Bank Annual Meetings in Bali on 12-14 October of the Bali Fintech Agenda in combination with the IMF Managing Director's Global Policy Agenda indicate that fintech is set to play a more prominent role to address monetary policy and financial stability concerns. This reflects mounting dissatisfaction with prevailing international monetary relations. The positive role attributed to fintech may hint at a new readiness to integrate fintech in monetary and financial policies. [...]

International dimension of central bank digital currencies

IMF-World Bank 2018 Annual Meetings

Conference, Bali, 11 October 2018

[...] I shall focus on the international dimension of central bank issued digital currencies (CBDC) especially how CBDC could address one of the long standing grievances in the international economy, namely inadequate supply and distribution of international liquidity. CBDC could offer a new basis for international currency use and as such have a profound impact on international trade and investments. [...]
