What Are CBDCs & Stablecoins?

Fintech & Payments

Payments are in a constant state of development, but the current market has seen the possibilities for payment types accelerate beyond what many in the market expected. To date, blockchain has had a mixed impact across payments and banking, but the rise of stablecoins and CBDCs threatens to accelerate this impact significantly.

As we discuss in our latest research , stablecoins and CBDCs are two ways of solving the same problem – how do you offer a better digitally native payments solution? Most existing payment types have been designed around traditional systems intended for in-person or telephone payments, such as credit cards, or even cash. Stablecoins and CBDCs are showing what can happen if a system is designed from the ground up as digital.

However, this begs the question: precisely what are CBDCs and stablecoins?
 

CBDCs

 
A CBDC is an additional form of money issued, monitored and controlled by a central bank. Similar to fiat currencies, the supply of CBDCs is also controlled by a central bank’s monetary and fiscal policies.
 
What makes CBDCs different to stablecoins and other forms of decentralised digital currencies is that, when issued by the central bank, it must be accepted as a form of payment by all within the market. Additionally, it must be a safe store of value by all consumers, merchants, stakeholders and government agencies.

However, similar to a stablecoin, a CBDC is pegged 1:1 to the corresponding fiat currency, meaning that the value of the crypto coin is always the same as the fiat currency. Additionally, as it is a digital currency, consumers are required to have a digital wallet, but do not need to have a traditional bank account to use and hold CBDCs.
 
CBDCs are fundamentally different to other forms of cryptocurrency. The intention is that a CBDC would largely rely on the existing payment infrastructure and would need to be integrated with core banking systems to enable payments without the need to create and install an entirely new financial infrastructure. Therefore, as an objective, the deployment of a CBDC is completely different to a stablecoin. A CBDC is designed to enhance and complement existing payment systems, whereas a stablecoin is designed to bypass them completely.
 
The corresponding digital wallets used for CBDCs can be used with smartphones, smart devices and wearables, in the same way as a typical digital wallet service that may or may not be linked to a card or bank account.
 

Stablecoins

 
A stablecoin is a cryptocurrency that has its value pegged to that of another currency, commodity or alternative financial instrument.

Stablecoins can be exchanged or integrated with other digital assets, as they are a store of value and medium of exchange through DLTs (Distributed Ledger Technology). Transactions using stablecoins do not rely on an intermediary to facilitate a settlement, which means that transactions can be settled almost instantly.

Additionally, this means that payments and transactions can be made 24/7, with no restrictions or wait times, as they do not rely on a payment facilitator. The reason stablecoins were developed was to combine the benefits of cryptocurrencies, including being encrypted and cryptographically secured, without the volatility associated with decentralised cryptocurrencies.
 
There are four main types of stablecoins, which are detailed below:
 
Fiat-collateralised stablecoins: A fiat-backed stablecoin is a cryptocurrency that is pegged to the value of a fiat currency to ensure it follows the price dynamics of its associated currency. Additionally, the stablecoin is backed by physical cash held in reserves.
 
Crypto-collateralised stablecoins: This is a completely decentralised way of creating a relatively more stable crypto coin, by backing the value of the stablecoin with digital asset reserves, instead of fiat cash reserves. It is key to note that this method of backing cryptocurrencies still leads to high levels of fluctuations and price volatility, but by over-collateralising the coins, the risk of the coin completely crashing is reduced.
 
Commodity-collateralised stablecoins: These are cryptocurrencies backed by a reserve of real assets such as oil or gold. Commonly, this works by pegging the value of one coin to a specific unit of a commodity. For example, a stablecoin may be backed to one fine ounce of gold held in a reserve.
 
Algorithmic stablecoins: These are coins that are not backed by any kind of asset, nor do they use any reserve. Instead, the stablecoin uses a completely algorithmic approach, which adjusts the supply of the coin in response to fluctuations in price, creating a price stability mechanism. An example of this would include incentivising users to sell a particular coin that is trading above a certain value, at a profit, to pull the price back down to a more stable rate. 
 
As stablecoins can function as independent blocks, they can operate with smart contracts to create payments and other financial services. Within this model, stablecoins can be transacted when certain conditions written into the code have been met, providing a fully automated solution.
 
However, stablecoins do have some limitations. Like traditional cryptocurrencies, stablecoins are not centrally controlled, they are distributed. This can raise a challenge for central banks and payment system regulators, who will seek greater control over the payment rails that are available within their areas of responsibility.
