The rapid growth of digital currencies has introduced a host of new terms and concepts, from NFTs to DeFi. Among these, stablecoins have emerged as a powerful and increasingly popular category of cryptocurrency. Unlike well-known tokens such as Bitcoin, Ethereum, or Dogecoin, stablecoins are designed to minimize price volatility, making them attractive to both investors and corporations.
This stability hasn’t gone unnoticed. As of May, the total supply of stablecoins surged to over $100 billion—a tenfold increase from just $10 billion a year earlier. This explosive growth has also drawn regulatory scrutiny. In July, U.S. Treasury Secretary Janet Yellen convened top economic leaders, including Federal Reserve Chair Jerome Powell and SEC Chair Gary Gensler, to discuss the implications and potential of stablecoins.
So what exactly are stablecoins, and why are they becoming so significant?
What Are Stablecoins and How Do They Differ from Other Cryptocurrencies?
Stablecoins are a type of digital currency whose value is directly tied to an external reference asset. These can include fiat currencies like the U.S. dollar or euro, or commodities such as gold and oil.
The key advantage of stablecoins is their relative price stability. Because they are pegged to less volatile assets, they avoid the extreme price swings common in traditional cryptocurrencies like Bitcoin or Ethereum, which are not backed by any physical or reserve assets.
Common Uses of Stablecoins
Trading and Transactions
The most widespread use of stablecoins is in cryptocurrency exchanges. Users often convert fiat currency into stablecoins to trade other digital tokens efficiently. Tether (USDT), for example, is widely used for this purpose despite facing criticism over its reserve claims.
Stablecoins also serve as a bridge for companies entering the crypto economy. Visa, for instance, uses USD Coin (USDC) to enable crypto transactions, allowing users to spend digital assets on everyday purchases. Coinbase debit cardholders can shop with USDC without incurring high transaction fees typically associated with crypto payments.
Decentralized Finance (DeFi)
Stablecoins are foundational to many DeFi applications, including yield farming—where users lend their tokens to earn interest. This creates opportunities for passive income within the crypto ecosystem.
Where to Buy Stablecoins and Why Investors Choose Them
Most major cryptocurrency exchanges, including Coinbase, Binance, and Kraken, offer stablecoins. Their appeal lies in reduced risk and lower volatility compared to traditional cryptocurrencies. This makes them especially attractive to institutional investors and those new to digital assets.

Popular Stablecoins in the Market
Tether (USDT)
Tether is the largest stablecoin by circulation, accounting for over half of the total market. It is pegged to the U.S. dollar but has faced regulatory concerns regarding its actual reserve holdings.
USD Coin (USDC)
As the second-largest stablecoin, USDC is also dollar-backed and widely used. It has gained traction through partnerships with firms like Visa. However, it too has encountered criticism over its asset-backing composition, which includes both cash and non-cash reserves.
Other Notable Stablecoins
Alternative stablecoins include Paxos Gold (backed by gold) and Petro (issued by Venezuela and backed by oil reserves). These illustrate the diversity of assets that can underpin stablecoin values.
Regulatory Landscape for Stablecoins
Currently, most stablecoins operate in a regulatory gray area. However, change appears imminent. Following the July meeting, Secretary Yellen emphasized the need for a robust regulatory framework. The Biden administration is expected to propose new policies in the coming months.
SEC Chair Gensler also highlighted the need for stronger investor protections, indicating that stablecoins will not be exempt from future regulations.
Relatedly, central bank digital currencies (CBDCs) are gaining attention as government-issued digital tokens. Countries like China are already piloting their digital yuan, and the U.S. Federal Reserve is expected to clarify its stance on both CBDCs and stablecoins later this year.
