Marshall Islands CBDC

The Marshall Islands CBDC project moves forward. Algorand, the project partner, reports that

blockchain for the world’s first national digital currency, the Marshallese sovereign (SOV), will be built using Algorand technology. The SOV will circulate alongside the US dollar and help the Marshall Islands efficiently operate in the global economy.

On the Future of Payments and Settlement

In its Quarterly Review, the BIS offers nice perspectives on the future of payments. Morten Bech and Jenny Hancock survey innovations in payments, and where the problems lie. Tara Rice, Goetz von Peter and Codruta Boar examine the fall in the number of correspondent banks. Morten Bech, Umar Faruqui and Takeshi Shirakami discuss cross border payments. Morten Bech, Jenny Hancock, Tara Rice and Amber Wadsworth discuss securities settlement. And Raphael Auer and Rainer Böhme explore design choices of a retail CBDC.

e-krona Pilot

The Riksbank starts a pilot project with Accenture to develop a technical solution for a retail e-krona.

Users shall be able to hold e-kronor in a digital wallet, make payments, deposits and withdrawals via a mobile app. The user shall also be able to make payments via wearables, such as smart watches, and cards.

The pilot runs for a year, on a distributed ledger, according to the Riksbank’s press release. More detailed information is contained in this note.

Digital Dollar Project

Accenture, the Digital Dollar Foundation, and FTI Consulting are pushing for a digital USD. They have formed the Digital Dollar Project

to advance exploration of a United States Central Bank Digital Currency (CBDC). The purpose of the Project is to encourage research and public discussion on the potential advantages of a digital dollar, convene private sector thought leaders and actors, and propose possible models to support the public sector. The Project will develop a framework for potential, practical steps that can be taken to establish a dollar CBDC.

Central Banks Zoom In on CBDC

According to a BIS press release, several leading central banks collaborate with the BIS on matters relating to the introduction of CBDC:

The Bank of Canada, the Bank of England, the Bank of Japan, the European Central Bank, the Sveriges Riksbank and the Swiss National Bank, together with the Bank for International Settlements (BIS), have created a group to share experiences as they assess the potential cases for central bank digital currency (CBDC) in their home jurisdictions.

The group will assess CBDC use cases; economic, functional and technical design choices, including cross-border interoperability; and the sharing of knowledge on emerging technologies. It will closely coordinate with the relevant institutions and forums – in particular, the Financial Stability Board and the Committee on Payments and Market Infrastructures (CPMI).

The group will be co-chaired by Benoît Cœuré, Head of the BIS Innovation Hub, and Jon Cunliffe, Deputy Governor of the Bank of England and Chair of the CPMI. It will include senior representatives of the participating institutions.

Sand Dollar

The Central Bank of the Bahamas introduces CBDC, according to a press release (December 2019).

The intended outcome of Project Sand Dollar is that all residents in The Bahamas would have use of a central bank digital currency, on a modernized technology platform, with an experience and convenience—legally and otherwise—that resembles cash. It is expected that this will allow for reduced service delivery costs, increased transactional efficiency, and an improved overall level of financial inclusion. The anonymity feature of cash is not being replicated, although the Sand Dollar infrastructure would incorporate strict attention to confidentiality and data protection.

BIS Innovation Hub Centre in Switzerland

From the SNB’s press release regarding the newly established BIS Innovation Hub Centre in Switzerland:

The Swiss Centre will initially conduct research on two projects. The first of these will examine the integration of digital central bank money into a distributed ledger technology infrastructure. This new form of digital central bank money would be aimed at facilitating the settlement of tokenised assets between financial institutions. Tokens are digital assets that can be transferred from one party to another. The project will be carried out as part of a collaboration between the SNB and the SIX Group in the form of a proof of concept.

The second project will address the rise in requirements placed on central banks to be able to effectively track and monitor fast-paced electronic markets. These requirements are arising in particular from the greater automation and fragmentation of the financial markets, but also from the increased use of new technologies.

Thomas Jordan and Agustín Carstens signed the Operational Agreement on the BIS Innovation Hub Centre in Switzerland yesterday.

“Libra Paves the Way for Central Bank Digital Currency,” finews and WNM, 2019

My VoxEU column now also on finews and World News Monitor, September 17, 2019.

Digital currencies involve tradeoffs. Libra resolves them less favorably than other projects, and less favorably than CBDC.

When confronted with the choice between the status quo and a new financial architecture with CBDC, most central banks have responded cautiously. But Libra or its next best replica will take this choice off the table – the status quo ceases to be an option. The new choice for monetary authorities and regulators will be one between central bank managed CBDC on the one hand and – riskier – private digital tokens on the other. Central banks have a strong interest to maintain control over the payment system as well as the financial sector more broadly and to defend the attractiveness of their home currency. Nolens volens, they will therefore introduce ‘Reserves for All’ or promote synthetic CBDCs. In economics, things take longer than one thinks they will, as Rudi Dornbusch quipped, but then they happen faster than one thought they could.

“On the Equivalence of Private and Public Money,” JME, 2019

Journal of Monetary Economics, with Markus Brunnermeier. PDF.

When does a swap between private and public money leave the equilibrium allocation and price system unchanged? To answer this question, the paper sets up a generic model of money and liquidity which identifies sources of seignorage rents and liquidity bubbles. We derive sufficient conditions for equivalence and apply them in the context of the “Chicago Plan”, cryptocurrencies, the Indian de-monetization experiment, and Central Bank Digital Currency (CBDC). Our results imply that CBDC coupled with central bank pass-through funding need not imply a credit crunch nor undermine financial stability.

Jean-Pierre Landau Argues for CBDC

In the FT, Jean-Pierre Landau argues that central banks should introduce central bank digital currency:

A CBDC would protect the pre-eminence of public money in a digitalised economy. It would maintain effective convertibility of private into public money and provide a defence against digital dollarisation.

For that purpose, a CBDC should be as close as possible to cash. It should be a complement, not a substitute, to bank deposits. It should not carry interest. Whether it should be anonymous, as cash currently is in certain limits, is a fundamental social choice. It must be openly debated as the digitalisation of money forces us to reconsider and rethink the place of privacy in our lives.

“Digitales Zentralbankgeld (Central Bank Digital Currency),” FuW, 2019

    • It is not central bank digital currency (CBDC) per se which might act as a game changer in financial markets. What will be key is how central banks accommodate the introduction of CBDC.
    • In principle, this accommodation can go very far, to the point where the introduction of CBDC does not affect macroeconomic outcomes.
    • But such complete accommodation is unlikely. On the one hand, central banks will want to exploit the new monetary policy options that CBDC opens up; that is, central banks will not choose to fully accommodate.
    • On the other hand, the introduction of CBDC increases transparency and this will increase political pressure; as a consequence, central banks will not be able to fully accommodate.

The Bank of England Welcomes Fintech

In the FT, Chris Giles, Caroline Binham, and Delphine Strauss report about plans of the Bank of England to let fintech companies

bank at Threadneedle Street and thereby offer payments systems on a level playing field with commercial banks.

The editorial board of the FT welcomes the plans; it seems to have in mind not only competition but also “synthetic” CBDC:

By offering fintech companies access to the BoE’s vaults, the governor may inject much-needed competition into the sector. What must follow is proactive regulation …

Commercial banks have traditionally had exclusive access to deposits at the UK’s central bank, offering them a competitive advantage through cheap banking services. … Another potential advantage for consumers is they could be paid the central bank’s often favourable interest rate directly — rather than relying on traditional banks to pass on rate rises.

Mark Carney outlined the plans in his Mansion House speech. Here are some excerpts from the section on digital finance:

… the Faster Payment System (FPS) launched a decade ago has made payments quicker (within two hours) and more cost effective by encouraging direct bank-to-bank transfers.

While mobile app PayM uses FPS to facilitate direct bank-to-bank payments between individuals via text, it requires both the sender and recipient to be signed up to the third party service. But few are. And FPS is not yet used for in-store or online purchases as the infrastructure required at the point of sale does not reliably exist in the UK.

In these regards, the UK is still a long way behind countries such as Sweden, the Netherlands and India …

The revolution of payments may not be driven by the old bank-based systems … Major changes are on the horizon … That’s why the Bank fully supports the Payments Strategy Review the Chancellor has launched this evening.

To support private innovation and to empower competition, the Bank is levelling the playing field between old and new. This means allowing competitors access to the same resources as incumbents while holding the same risks to the same standards.

… we are now making it easier for a broad set of firms to plug in and compete with more traditional providers. In July 2017, we became the first G7 central bank to open up access to our payment services to a new generation of non-bank PSPs. …

Responding to demands from innovators, the RTGS rebuild will also now provide API access to users to read and write payments data, as well as implementing a system whereby each payment will be tagged with information in a standardised format across the world. This global messaging standard will speed up settlement both domestically and across borders.

… Today, the Bank of England is announcing plans to consult on opening access to our balance sheet to new payment providers. Historically, only commercial banks were able to hold interest-bearing deposits, or reserves, at the Bank. …

From the Bank’s perspective, expanding access can improve the transmission of monetary policy and increase competition. It can also support financial stability by allowing settlement in the ultimate risk free asset, and reducing reliance on major banks. Users should benefit from the reduced costs and increased certainty that comes with banking at the central bank. …

This access could empower a host of new innovation. … settlement systems using distributed ledger technology … consortia, such as USC, propose to issue digital tokens that are fully backed by central bank money, allowing instant settlement. This could also plug into ‘tokenised assets’ – conventional securities also represented on blockchain—and smart contracts. This can drive efficiency and resilience in operational processes and reduce counterparty risks in the system, unlocking billions of pounds in capital and liquidity that can be put to more productive uses.

The potential transformation in retail payments is even more fundamental. …

The Bank of England approaches Libra with an open mind but not an open door. Unlike social media for which standards and regulations are being debated well after they have been adopted by billions of users, the terms of engagement for innovations such as Libra must be adopted in advance of any launch.

Carney also outlines plans to support initiatives that aim at giving households and firms control over “their” data:

To make real inroads, SMEs must be able to identify the data relevant to their businesses, incorporate it into their individual credit files, and easily share these files with potential providers of finance through a national SME financing platform.

This would put into practice the recommendations from Professor Jason Furman’s Digital Competition Panel report on how to extract value from data and promote competition. One of the most important recommendations in this regard is to give consumers control of their data. This would allow consumers to move their personal information from one platform to another and avoid lock-in effects, opening the door to new services. To some extent, this is what Open Banking hopes to achieve. Although to make this a success means establishing common off the-shelf API standards and operating platforms onto which developers can build. …

It is not for the Bank of England to build this platform but we can help lay some of groundwork. The messaging standards we are adopting in the new RTGS will also include tagging payments with a unique ID called a Legal Entity Identifier (LEI).

The Future of Money – CBDC and Beyond

At the conference of “Positiva Pengar” and “Monetative” in Stockholm, I argued that it is not so much the introduction of CBDC which would make a difference, but the policies accompanying such an introduction. This view is backed by research of Markus Brunnermeier and myself, as well as by myself.

Many of the proponents of the sovereign money movement appeared open to the argument. Some of the followers, however, did not; they associate CBDC with many benefits that money, in whatever form, will not be able to deliver.

We develop a generic model of money and liquidity that identifies sources of liquidity bubbles and seignorage rents. We provide sufficient conditions under which a swap of monies leaves the equilibrium allocation and price system unchanged. We apply the equivalence result to the “Chicago Plan,” cryptocurrencies, the Indian de-monetization experiment, and Central Bank Digital Currency (CBDC). In particular, we show why CBDC need not undermine financial stability.

“Public versus Private Digital Money: Macroeconomic (Ir)relevance,” VoxEU, 2019

VoxEU, March 20, 2019, with Markus Brunnermeier. HTML.

Both proponents and opponents have suggested that CBDC would fundamentally change the macroeconomy, either for the better or the worse. We question this paradigm. We derive an equivalence result according to which the introduction of CBDC need not alter the allocation nor the price system. And we argue that key concerns put forward in discussions about CBDC are misplaced.

“Reserves For All? Central Bank Digital Currency, Deposits, and their (Non)-Equivalence,” IJCB

Accepted for publication in the International Journal of Central Banking. PDF.

This paper offers a macroeconomic perspective on the “Reserves for All” (RFA) proposal to let the general public hold electronic central bank money and transact with it. I propose an equivalence result according to which a marginal substitution of outside money (e.g., RFA) for inside money (e.g., deposits) does not affect macroeconomic outcomes. I identify key conditions for equivalence and argue that these conditions likely are violated, implying that RFA would change macroeconomic outcomes. I also relate the analysis to common arguments found in discussions on RFA and point to inconsistencies and open questions.

“Digital Money: Private versus Public,” VoxEU Book, 2019

In Antonio Fatás, editor, The Economics of Fintech and Digital Currencies, VoxEU book, London, March 2019, with Markus Brunnermeier. PDF.

We address five key concerns that are frequently put forward:
1. Aren’t digital currencies just a hype, now that crypto ‘currencies’ like Bitcoin have proved too volatile and expensive to serve as reliable stores of value or mediums of exchange? This confuses things. A central bank digital currency (CBDC) is like cash, only digital; Alipay, Apple Pay, WeChat Pay, and so on are like deposits, only handier; and crypto currencies are not in any way linked to typical currencies, but they live on the blockchain.
2. Doesn’t a CBDC or ‘Reserves for All’ choke investment by cutting into bank deposits? No, because new central bank liabilities (namely, a CBDC) would fund new investments, and this would not in any way imply socialism or a stronger role of government in investment decisions.
3. Wouldn’t a CBDC cut into the profits that banks generate by creating deposits? Less money creation by banks would certainly affect their profits. But if this were deemed undesirable (by the public, not by shareholders and management) then banks could be compensated.
4. Wouldn’t ‘Reserves for All’ render bank runs more likely, undermining financial stability? We argue that, in fact, the opposite seems more plausible.
5. Aren’t deposit insurance, a CBDC, Vollgeld/sovereign money, and the Chicago Plan all alike? There are indeed close parallels between the different monetary regimes. In a sense, “money is changing and yet, it stays the same”.
