Ep. 171 – Exploring CBDCs – insights from the Bank for International Settlements

Central bank digital currencies (CBDCs) are increasingly being talked about in the press with announcements of initiatives from different central banks working on CBDCs coming out left right and centre. Few however are as forward thinking and embracing a collaborative approach as the Bank for International Settlements (BIS). For this podcast we are joined by Daniel Eidan,  Adviser and Solution Architect at the Bank for International Settlements (BIS) in the Innovation Hub where he builds technology solutions for the central banking community with a special focus on blockchain and CBDC. He will share with us some of the exciting work his team are doing for driving CBDC forward.

 
What is blockchain?
Blockchain and DLT is often referred to as Web 3.0 whilst the internet of today is Web 2.0.

Web 2.0 enables to globally connect communications protocol whilst blockchain and Web 3.0 isn’t just about putting communication protocols digitally but to store value digitally. What blockchain enables is to execute computations between different members and keep a record of state. Essentially as Daniel mentions we can encapsulate value. Value can be cryptocurrencies, central bank digital currencies, contracts and many other forms of value. This wasn’t something possible in the Web 2.0 because the fundamentals weren’t there.

 
What are CBDCs?
To fully understand what CBDCs, central bank digital currency, are you first need to understand what is a currency. Money and currency in general have three attributes:

* They are a unit of account
* A store of value
* A medium of exchange

What central bank digital currencies do is that they digitise those three attributes.


 
To explain how this happens Daniel uses the “money flower” approach which looks at its four different attributes:

* Is it universally accessible?
* Is it electronic?
* Is it issued by a central bank?
* Is it moved around in a peer to peer way?

A retail form of CBDC will have all four of the money flower attributes. It will be universally accessible, it will be electronic, it will be issued by a central bank and contain central bank liability, and it will transact in a peer to peer way.

What is important to recognise is that most of the retail monetary base is not central bank money, it’s commercial bank money. For example, when you deposit money at you bank it is likely that a large part of your fiat currency is with a claim against your commercial bank. Then through a set of mechanisms that claim is insured by potentially a central bank or a federal institution.

The only claim that retail can have against a central bank is in the form of cash. Cash of course is a tiny percentage of the total amount of money individuals have. What CBDC does is takes that cash liability, in a retail context, to exist in a digital context in a way that’s accessible to anyone.

The question is what happens to individuals who do not have a smart device, or electricity, or WIFI? In addition, how is universal accessibility attained to individuals with disability issues or are elderly? There are a number of technical solutions that can help to lower this barrier but it is one that is a challenge in terms of the last mile for reaching ubiquitous CBDC.

In the case of wholesale, the case for CBDCs is to broaden the base of digital currency from tier one institutions that are regulated domestically to fintechs, startups and perhaps banks in other jurisdictions. So, it's really extending the promise and the capabili...
