Imagine a world where the cash in your wallet is replaced by a digital version issued by the central bank. This is not a distant daydream; It is the reality of Central Bank Digital Currencies, otherwise known as CBDCs. 

As aspiring professionals within the fields of law, economics, finance, business, technology and beyond, understanding CBDCs is vital. You must be able to anticipate the future of money and understand your undeniable role within it. 

What Exactly is a CBDC? (It's not another version of Bitcoin or Ethereum, if that’s what you’re thinking) 

At its core, a Central Bank Digital Currency (CBDC) is a digital form of a country's fiat currency, issued and regulated by its central bank. Unlike volatile and decentralised cryptocurrencies like Bitcoin, a CBDC is centralised, stable, and backed by the full faith and credit of the government. Its value is fixed, mirroring its physical counterpart, and is essentially a digital banknote. 

CBDCs typically fall into two major categories:

1. Wholesale CBDCs: These are primarily for financial institutions such as banks, and are aimed at facilitating inter-bank transfers and settlements. 

2. Retail CBDCs: These are designed for public use in everyday transactions. For you and me, basically. 

From Necessity to Innovation: 

Before the recent global surge of interest in CBDCs, parts of the African continent pioneered digital payment solutions or mobile money forms out of sheer necessity. 

In many African countries, traditional banking infrastructure was previously limited, leaving a large portion of the population underbanked. This environment fostered remarkable innovation in mobile banking. Kenya's M-Pesa is a prime example, demonstrating how mobile payment systems could extend financial services to those without traditional bank accounts, significantly enhancing financial inclusion. 

This early digital transformation experience in developing economies is now seen as a precursor, offering lessons on how new digital currencies can "leapfrog existing financial infrastructure, similar to how mobile phones allowed many nations to bypass landline technology".

The double-edged sword of CBDCs

Central Banks worldwide are exploring CBDCs for a variety of compelling reasons, based on the potential they can unlock for our economies. 

What are some of the attractive features of Digital Money that are Capturing the Attention of Central Banks? 

1. Financial Inclusion: This is a key motivation, especially in emerging markets. The aim here is to provide secure, low-cost financial services to the unbanked and underbanked. 

How exactly? With features like low transaction costs and offline functionality. This can be seen as giving access to the room (The formal economy)  

As the Federal Reserve Board (USA) highlights, a CBDC has "the potential to improve welfare by reducing financial frictions in deposit markets, by boosting financial inclusion, and by improving the transmission of monetary policy".

2. Improved Payment Efficiency: CBDCs could make domestic and international payments faster, safer, and cheaper. Cross-border transactions, in particular, could see costs reduced by "shortening payment chains and creating more competition among service providers".

3. Monetary Policy and Stability: CBDCs could give central banks a new policy tool, especially if they earn interest, and help monetary policy function more smoothly. They could also strengthen the financial system by lowering frictions and offering a safe alternative to bank deposits, while reducing risks from volatile private stablecoins or supporting stronger ones.

4. Innovation and Cost Reduction: A CBDC can increase private-sector innovation in banking and payments, and also promises to reduce the substantial costs associated with printing, transporting, and managing physical cash.

5. National Security and Sovereignty: In an era of increasing geopolitical competition, "nations may increasingly view digital payment infrastructures as strategic assets, sovereign capabilities too vital to entrust to foreign firms," as Jens Larsen, head of geoeconomics at Eurasia Group, points out.

What are the Risks Associated? 

Despite the upside, we find Central Banks hesitant to adopt CBDCs and here are some of the reasons why:

1. Bank Disintermediation: A frequently mentioned concern is that CBDCs could draw deposits away from commercial banks, especially if interest-bearing, potentially increasing banks' funding costs and reducing their lending capacity.  This could destabilise the banking sector and "contract bank credit", as deposits are a major funding model for banks. Therefore, smaller banks are more likely to take the hit, especially without many alternative funding sources. 

2. Privacy and Surveillance: Unlike anonymous physical cash, a centralised CBDC design could enable governments to track every transaction, raising significant concerns about surveillance. 

3. Cybersecurity Risks: A centralised digital currency system presents an attractive target for cyberattacks, posing a significant systemic risk to the financial system.

4. Public Adoption Challenges: Generating public demand has proven difficult, even in early adopter nations. In the Bahamas, the Sand Dollar accounts for less than 0.41% of currency in circulation, leading the government to "effectively force them to distribute [the CBDC]" through commercial banks. Nigeria's eNaira also faced slow initial adoption, prompting drastic measures to encourage its use.

Adoption of CBDCS: A Few Case Studies 

1. China's Digital Yuan (e-CNY): China is a front-runner, with the e-CNY being the largest CBDC pilot globally. Its motivations are strategic, aiming to strengthen its currency, provide an alternative to the US dollar, and enhance surveillance. China's approach involves a two-tiered architecture and a ban on private cryptocurrencies.

2. The Bahamas (Sand Dollar) & Nigeria (eNaira): These were among the first to launch retail CBDCs, primarily for financial inclusion. However, as mentioned, they have faced significant hurdles in adoption. 

3. Ghana (eCedi) & South Africa (Project Khokha): Ghana is piloting a retail eCedi for similar reasons of financial inclusion and digital payments. South Africa, conversely, is experimenting with a wholesale CBDC, Project Khokha, for interbank transfers using distributed ledger technology.

4.  European Union (Digital Euro): The EU is accelerating plans for a digital euro, driven by concerns that the US's promotion of dollar-backed stablecoins could strengthen the dollar's role and undermine Europe's financial stability and strategic autonomy. The European Central Bank (ECB) is exploring various technologies, including public blockchains, despite privacy concerns.

5. United States: A Cautious Outlier: The US Congress has passed legislation banning a retail digital dollar, reflecting deep mistrust of government surveillance. While a retail CBDC is rejected, the US continues to research wholesale cross-border payments through Project Agorá, collaborating with other major central banks. The Federal Reserve emphasises a cautious approach, not implying a definitive move to issue one but researching its potential to "improve on an already safe and efficient U.S. domestic payments system".

As James Wallis, Vice-President of Central Bank Engagements at Ripple, notes, "It's not central banks’ mission to be innovators. They can control the core infrastructure, but the private sector will really bring in most of the new use cases that will benefit citizens". This highlights the ongoing tension and potential for public-private collaboration.
