What Are Stablecoins?
Unlike Bitcoin (BTC) or Ethereum (ETH), which can be pretty volatile, stablecoins are built to hold a steady value. They still come with all the blockchain perks like fast transactions and low fees, but their price is usually tied to something stable, like the US dollar, the euro, other crypto, or even commodities like gold and oil.
The main reasons people use stablecoins are:
- Price Stability. They don’t have the wild price swings of other cryptos, making them better for everyday use.
- Efficient Transactions. Stablecoins make it easy to send money quickly and cheaply across the globe, no banks needed.
- Cryptocurrency Trading. Traders often park their funds in stablecoins to protect against market volatility.
- DeFi Applications. In decentralised finance (DeFi), stablecoins are used for lending, borrowing, and earning interest without worrying about market ups and downs.
How Do Stablecoins Work?
Stablecoins stay stable thanks to different mechanisms, all aimed at keeping their price close to the asset they’re pegged to. Most stablecoins rely on collateral, meaning they hold reserves to back up their value. This system serves a few key purposes:
- Trust. Collateral helps ensure that the stablecoin keeps its value, so users know they can exchange it for a set amount of the underlying asset, like fiat or gold.
- Risk Mitigation. Especially with crypto-backed stablecoins, having extra collateral helps cushion against price swings.
- Redemption Guarantee. You can traлde stablecoins for the underlying asset, which is a safety net during market chaos when other cryptos are all over the place.
- Regulatory Compliance. Holding reserves shows that issuers are managing risks responsibly and playing by the rules.
How this collateral works can vary. Some stablecoins, like USD-pegged ones, hold a dollar in reserve for each coin. Others, backed by more volatile assets like crypto, may hold extra collateral to handle price fluctuations. And then, there are algorithmic stablecoins, which adjust supply based on demand to keep the price stable without needing traditional reserves.
Types of Stablecoins
There are several types of stablecoins, each using a different method to keep their value stable:
1. Fiat-Collateralized Stablecoins
These are backed by traditional currencies like the US dollar or euro. For each stablecoin issued, there’s an equivalent amount of fiat money held in reserve, making sure the value stays consistent. For example, Tether (USDT) and Circle (USDC) are pegged to the U.S. dollar, so each coin is worth about $1. They’re commonly used for trading, remittances, and payments, providing a stable option in the volatile crypto market.
2. Crypto-Collateralized Stablecoins
These are backed by other cryptocurrencies and are usually over-collateralized to handle the volatility of the underlying assets. A good example is MakerDAO’s DAI, which is pegged to the U.S. dollar but backed by crypto. Users lock up assets like Ethereum in a smart contract to generate stablecoins, and algorithms help keep the value steady. They’re popular in decentralized finance (DeFi) platforms for trading, lending, and earning interest without relying on centralized institutions.
3. Algorithmic Stablecoins
Instead of holding reserves, these stablecoins use algorithms and smart contracts to control supply and maintain price stability. When the price rises, more coins are issued, and when it drops, coins are bought back and burned. Frax (FRAX) is an example, combining collateral with algorithmic adjustments. Algorithmic stablecoins are used in DeFi projects where decentralisation is key, though they come with risks due to their complex mechanisms.
4. Commodity-Backed Stablecoins
These are tied to physical assets like gold, oil, or real estate. For example, Paxos Gold (PAXG) is backed by gold reserves. One token typically represents a set amount of the commodity. These stablecoins are popular among investors who want exposure to commodities without physically holding them, offering a hedge against inflation and a stable store of value in the crypto world.
Different stablecoins fit different needs. Some are better for everyday transactions, while others are more suited for investing or trading when you need stability in a volatile market.
Stablecoins vs. Traditional Assets
Stablecoins have become an important part of the financial world, but many still wonder how they stack up against traditional assets. They’re designed to bring stability to the often volatile crypto market by pegging their value to established currencies like the U.S. dollar. But, as the BIS points out, this reliance reveals some weaknesses in cryptocurrencies as standalone systems.
Institutional Support and Trust
Traditional assets, like fiat currencies, are backed by central banks that enforce strict policies and regulations. This institutional support creates stability and trust, something stablecoins often lack. When markets get shaky, as seen with the collapse of TerraUSD and Luna, stablecoins can quickly lose their footing.
Fragmentation and Inefficiency
The crypto world is fragmented, with thousands of coins across different blockchains. This can lead to inefficiencies, like high transaction fees and network slowdowns. Traditional financial systems, backed by centralized authorities, offer a more consistent and smooth experience, with fiat currencies accepted everywhere.
The Upside of Stablecoins
Still, stablecoins have their perks. They enable faster cross-border transactions and make it easier to trade between different cryptocurrencies. Their programmability through smart contracts brings new efficiencies, like automated payments, which traditional finance is just beginning to explore. Some believe that central banks could eventually adopt certain blockchain features while keeping the stability of traditional currencies.
In short, stablecoins have their strengths and weaknesses. While they’re great for specific uses in the digital economy, they’re not quite ready to replace the stability, regulation, and universal acceptance that fiat currencies and traditional financial systems provide.
Benefits and Risks of Stablecoins
Benefits:
- Faster Transactions. Stablecoins make near-instant transfers, especially across borders, unlike traditional bank transfers that can take days.
- Global Accessibility. Anyone with internet access can use stablecoins, making them a great option for people in regions with limited banking services.
- Lower Fees. Without banks as intermediaries, stablecoin transfers often come with lower fees, especially for cross-border payments.
- Transparency. Every stablecoin transaction is recorded on a public blockchain, offering more transparency than traditional banking.
- 24/7 Availability. Stablecoins are always available, allowing transactions at any time, unlike traditional banks.
Risks:
- Regulatory Uncertainty. The rules around stablecoins are still being figured out, which could lead to legal issues or usage restrictions.
- Collateral and Trust Issues. If the reserves backing a stablecoin are mismanaged or not transparent, its value could be at risk. The collapse of TerraUSD in 2022 is a good example of how things can go wrong.
- Market Manipulation. The crypto market can be manipulated, which might affect stablecoin prices and their ability to hold value.
- Technical Vulnerabilities. Like all digital assets, stablecoins are at risk from hacking, smart contract bugs, and other tech problems that could lead to financial losses.
- Dependence on Traditional Systems. Since stablecoins are often pegged to fiat currencies, they’re vulnerable to the same risks as the currency they’re tied to, like inflation or government policies.
- Liquidity Risks. In tough market conditions, it might be hard to convert stablecoins back into fiat or other assets without a big price drop.
- Limited Adoption. Stablecoins are still not widely accepted for everyday transactions.
Popular Stablecoins in the Market
Stablecoins have become a key part of the cryptocurrency world, bridging the gap between traditional money and digital currencies. Since 2014, over 150 stablecoins have launched, with 96 listed as of August 2023, according to S&P Global.
Here are some of the most popular stablecoins and what makes them stand out:
1. Tether (USDT)
One of the oldest and most widely used stablecoins, Tether (USDT) is pegged to the U.S. dollar, making it a go-to for traders looking to avoid volatility. It’s accepted on most exchanges, making it easy to move in and out of the crypto market.
2. USD Coin (USDC)
Backed by U.S. dollars held in reserve, USDC is known for its transparency and regular audits. Created by Circle and Coinbase, it’s a reliable option for those wanting a stable digital asset, with each coin pegged to one U.S. dollar.
3. Dai (DAI)
Dai is a decentralized stablecoin from MakerDAO, backed by cryptocurrencies rather than U.S. dollars. Users lock up crypto as collateral to generate Dai, making it popular in decentralized finance (DeFi) for lending, borrowing, and trading without needing banks.
4. Binance USD (BUSD)
Created by Binance in partnership with Paxos, BUSD is fully backed by U.S. dollars held in reserve. It’s widely used for trading on the Binance platform and other exchanges, offering convenience and flexibility.
5. TrueUSD (TUSD)
Backed by U.S. dollars held in escrow, TrueUSD (TUSD) offers transparency through third-party audits. It’s a straightforward, reliable stablecoin for those looking for a stable store of value in the digital currency world.
Future of Stablecoins
Stablecoins have carved out a significant place in the crypto world, but their future holds both opportunities and challenges. As they continue to evolve, stablecoins could reshape both digital and traditional finance. So, what’s next?
Growing Influence and New Players
Despite occasional “depegging” issues, stablecoins remain crucial in the crypto ecosystem, especially for trading and DeFi. PayPal’s launch of its own stablecoin, PYUSD, in August 2023 shows how stablecoins are moving beyond just crypto enthusiasts and into mainstream finance. But with this growth comes the need for stronger regulation to prevent them from disrupting the global economy.
Regulatory Landscape: A Global Puzzle
Regulation will play a huge role in shaping the future of stablecoins, and countries are taking different approaches.
- EU. In 2023, the EU passed MiCA, which places strict requirements on stablecoin issuers, including holding a 1:1 liquid reserve. This regulation aims to increase transparency and reduce risks but may limit features like interest-bearing accounts.
- UK. The UK’s new rules for fiat-backed stablecoins, starting in November 2023, focus on ensuring these coins stay stable. They’re also considering how to regulate foreign stablecoins used in UK payment systems.
- U.S. While there’s no federal law for stablecoins yet, U.S. regulators are paying attention. For now, stablecoins fall under anti-money laundering rules, and some states, like New York, have introduced strict requirements for dollar-backed stablecoins.
As more countries develop their own regulations, stablecoins will need to adapt to different rules around the world.
Innovation and DeFi Integration
Stablecoins are deeply embedded in DeFi, powering lending, borrowing, and liquidity pools. As stablecoins continue to evolve, they could offer more innovative products and even partner with Central Bank Digital Currencies (CBDCs). Tokenising real-world assets (RWAs), like debt or securities, is another possibility, linking stablecoins more closely to traditional markets and offering investors higher yields.
The Role of Central Bank Digital Currencies (CBDCs)
A big question is how stablecoins will coexist with CBDCs. Unlike stablecoins, which are often privately issued, CBDCs are digital versions of a country’s currency, issued by central banks. They offer many of the same benefits—like instant payments and cross-border efficiency—but with the backing of a central bank, adding an extra layer of trust.
There are two types of CBDC:
- Retail CBDC (rCBDC). For everyday consumer use, like buying goods and services.
- Wholesale CBDC (wCBDC). Used for interbank transactions and financial institutions.
Conclusion
More than 130 countries are exploring Central Bank Digital Currencies (CBDCs). While they offer potential benefits, they also come with risks, like bank runs, cybersecurity threats, and infrastructure challenges. CBDCs could also shake up global payment systems and even impact national security if they’re used to sidestep international sanctions.

CBDCs could become a competitor to stablecoins, especially those pegged to fiat currencies. Users might prefer CBDCs for their government backing, stability, and regulatory compliance. However, CBDCs are not rolling out as fast as stablecoins.
The competition in the stablecoin space will continue to grow. New players will likely introduce innovative features, while established ones will need to evolve, focusing on user experience, transparency, and trust.
