The cryptocurrency market has long been characterized by extreme volatility, as evidenced again by the recent large price movements of Bitcoin. While this volatility has been a feature of Bitcoin since its inception, the recent large price fluctuations are a stark reminder of the volatility and risks associated with all unbacked cryptocurrencies.
Stablecoins were first introduced in 2014 to address this inherent volatility in the cryptocurrency market. Developed as trading pairs for cryptocurrencies such as Bitcoin, their primary purpose was to combat price volatility, which some believed made cryptocurrencies unsuitable for everyday transactions and less viable as a store of value.
Stablecoins aim to solve this perceived problem by offering the benefits of digital currencies, such as fast, cross-border transactions, while maintaining a consistent value, usually pegged to a fiat currency such as the US dollar.
By the end of 2023, the stablecoin market had grown to a sizable size, albeit with some pretty significant ups and downs along the way. Currently, the total stablecoin market capitalization is around $120 billion, down significantly from its peak of over $180 billion in 2022. This decline can be attributed to a combination of changing investor sentiment, challenging cryptocurrency market conditions, and the attractive returns offered by traditional equity and income markets.
However, despite the decline, stablecoins still make up a large portion of the cryptocurrency landscape, accounting for roughly 6.5% of the total cryptocurrency market capitalization. The largest stablecoin, Tether (USDT), accounts for over $80 billion of this total, followed by USD Coin (USDC) at roughly $26 billion. While these figures pale in comparison to the market capitalizations of the likes of Bitcoin and Ethereum, they are still an important indicator of the importance of stablecoins in the cryptocurrency ecosystem.
Stablecoins aim to provide a more stable digital currency option compared to traditional cryptocurrencies by employing different mechanisms tailored to each type. The three main types are fiat-collateralized stablecoins, crypto-collateralized stablecoins, and algorithmic stablecoins.
Fiat-collateralized stablecoins are often thought of as being fully backed by traditional fiat currency, but in reality they are backed by reserves that consist primarily of U.S. Treasury bills and short-term debt. This gives them certain risks, such as interest rate risk (interest rate fluctuations can affect the value of these securities) and liquidity risk (which can be problematic if these securities need to be quickly converted into cash).
Crypto-collateralized stablecoins leverage other cryptocurrencies as collateral, bringing additional risks associated with crypto market volatility, while algorithmic stablecoins use smart contracts to adjust supply based on demand, which can expose the underlying algorithm to vulnerabilities and can lead to large, unexpected economic fluctuations that can make the coin's value unstable. Each type of stablecoin has its own pros and cons, but they all share the common goal of offering a more stable alternative to traditional cryptocurrencies.
Initially, the stablecoin market experienced significant growth as investors and traders sought refuge from the volatility of cryptocurrencies. However, this growth has not been without challenges.
The collapse of algorithmic stablecoin Terra sent shock waves through the cryptocurrency world in May 2022. Despite not being a true stablecoin in the traditional sense, Terra's collapse severely damaged confidence in the entire stablecoin market, leading to a period of decline and increased scrutiny.
Terra's collapse was a reminder that stablecoins are more complicated than their name suggests. Although stablecoins have proven useful as a means to facilitate cryptocurrency transactions and cross-border payments, they face several challenges before they can become a widespread payment method. Issues such as scalability, transaction speed, and costs still need to be addressed for stablecoins to compete with traditional payment systems.
There is also concern about the risk of de-pegging, where the value of a stablecoin diverges from the currency or other asset it is linked to, as evidenced by the fact that even the largest stablecoins still experience volatility. To address this, stablecoins such as Terra and FDUSD have implemented certain mechanisms to manage and report collateral more effectively.
Terra uses a dual-token system to balance TerraUSD and LUNA, absorbing volatility and maintaining stability through automatic supply adjustments. FDUSD maintains reserves at certain thresholds with real-time monitoring and transparent reporting. These strategies aim to mitigate the risk of depegging and increase the stability and reliability of the stablecoin.

Despite this risk of de-pegging, stablecoins offer many benefits, especially in developing countries. For example, stablecoins have attracted particular attention in Africa due to the continent's unique and challenging financial environment. With large unbanked populations and currency instability issues in many countries, stablecoins have the potential to address the need for financial inclusion and act as an effective hedge against inflation.
Countries such as Nigeria, Kenya and South Africa are leading the adoption of stablecoins in Africa due to factors including remittance needs, limited access to formal financial services and the growing popularity of cryptocurrencies.
As the stablecoin market continues to evolve globally, the need for a clearer regulatory framework is increasingly being recognized. Regulatory uncertainty remains a significant obstacle to investor confidence and widespread adoption. Debates continue in the United States and other major economies over how to classify and oversee stablecoins. Resolving these challenges is crucial to the long-term viability and growth of the stablecoin market.
In Africa, regulatory responses vary across the continent, with some countries taking a more cautious approach while others are more open to innovation. Kenya is considering regulations to prevent illicit activity, and South Africa plans to have comprehensive regulations for tokenized deposits and crypto assets in place by 2025. Companies such as Binance are actively in discussions with regulators to promote safe and efficient crypto markets.
Looking to the future, stablecoins will likely continue to play a key role in shaping the digital economy both globally and in Africa, with recent stablecoin initiatives from major financial services providers such as PayPal and Visa signaling growing institutional interest in this form of pegged cryptocurrency stablecoin.
However, the entire payments landscape is also evolving, as evidenced by the development of central bank digital currencies (CBDCs) and tokenized bank deposits, which could provide alternatives to privately issued stablecoins and hinder their path to wider adoption.
That said, as the cryptocurrency market matures and regulatory frameworks continue to evolve, stablecoins may come into their own as a useful bridge between the worlds of traditional finance and cryptocurrency.
But their long-term success will depend on their ability to deliver on the promise implied in their name: to finally provide the stability that many cryptocurrency investors and users desire.
