Stablecoins are a type of cryptocurrency designed to maintain a stable value, e.g., 1 stablecoin equals 1 U.S. dollar.
They achieve this by pegging their value to traditional currencies such as the U.S. dollar and the euro through various mechanisms.
Key Takeaways
- Stablecoins are cryptocurrencies designed to hold a steady value, typically pegged 1:1 to a major fiat currency.
- Most stablecoins are backed with reserves of cash, short-term government bonds, and other assets.
- Crypto trading and cross-border payments are currently the largest use cases for stablecoins.
What Is a Stablecoin?
Stablecoins emerged in 2014 as a response to the extreme volatility of other cryptocurrencies like Bitcoin (BTC).
Just before you go
Initially, they granted crypto users/traders a haven to hold dollar-pegged assets on the blockchain without needing to cash out to a traditional bank.
Since then, stablecoins have emerged as one of the fastest and cheapest ways to transfer value around the world 24/7.
U.S. dollar-denominated stablecoins are the most widely used; leading examples include Tether (USDT), USD Coin (USDC), Dai (DAI), and PayPal (PYUSD).
Some are pegged to the euro, other currencies, and commodities like gold. Others leverage algorithms rather than traditional reserves to maintain their stability.
Common Uses of Stablecoins
Stablecoins now serve several practical uses in crypto and traditional finance:
- Trading: Investors leverage them when buying and selling volatile cryptocurrencies.
- Cross-border payments: Fast, low-cost international transfers.
- Decentralized Finance (DeFi): Stablecoins are the foundation of borrowing, lending, and yield platforms.
- Regular daily spending: Increasing adoption in everyday transactions, payroll, and business settlements.
- Web3 Bridge: They make it easier to move value on and off blockchains.
How do Stablecoins Work?
Stablecoins have different approaches to maintaining their value:
Fiat Backed
These are the most common type of stablecoins.
For every token issued, the issuer holds an equal amount of cash, cash equivalents, or short-term government securities. USDT and USDC work like this.
Crypto-collateralized
This type is backed by other cryptocurrencies that are locked in smart contracts.
They typically shield themselves from price drops by over-collateralizing their reserves.
DAI is a leading collateral-backed stablecoin. In recent years, it has diversified its reserve mix to include centralized stablecoins and tokenized real-world assets.
Algorithmic
Algorithmic stablecoins rely on computer code to manage the token supply autonomously.
In short, when the price rises above target, more tokens are created and sold. When the price is below target, the system incentivizes users to destroy or lock tokens/
This model is fragile and is now subject to even more public/regulatory scrutiny following the collapse of TerraUSD.
Looking Ahead
The growing role of stablecoins in both crypto finance and crypto markets continues to grow,
Stablecoins aren’t without their problems. Depegging can cause significant damage to markets and the businesses that participate in them.
So, it stands to reason that if stablecoins “take off” into the mainstream, the system will be under even more pressure, and the systemic risks of a depeg could be even greater.
Regulation is becoming stricter, if not fleshed out (finally) in major economies around the world. This will affect how and where stablecoins can operate over the coming years.
