The market for stablecoins – crypto assets backed by traditional financial assets such as the US dollar or gold – has exploded as the coins have gained popularity as a reliable means of trading other digital assets. The boom in retail investing during the pandemic has also led to an increased demand for stablecoins such as Tether (USDT) and USD Coin (USDC) to facilitate trading. 

In September 2021, almost 75% of trading volume on crypto platforms involved a stablecoin, according to the ECB report. Moreover, with US dollar-backed stablecoins being increasingly used as a medium of exchange, the use of these stablecoins has grown beyond the cryptocurrency universe to enter the realm of cross-border payments and foreign remittance. 

According to data firm Statista, the total market capitalisation of all stablecoins has risen by nearly 600% in the year since the pandemic started in January 2020. At the time of writing, 24 January 2022, CoinMarketCap shows the total stablecoin market cap at $170bn.

How do stablecoins work? Looking beyond the stablecoin definition, we explore the  expanding functions and use cases of these crypto assets, assess the risk factors you need to consider when trading them, and offer a brief guide to the list of stablecoins to watch in 2022.

Most stable cryptocurrencies: Creation and uses

What are stablecoins? In brief, stablecoins are cryptocurrencies that hold a stable price and are backed by reserve assets, such as a fiat currency, commodities, or other cryptocurrencies. 

Tether (USDT) was the first stablecoin to gain prominence in the crypto universe. According to its white paper, Tether was initially issued on the bitcoin blockchain, and each USDT token is backed in a one-to-one ratio by one US dollar.

Fiat-backed stablecoins like USDT and USD coin (USDC) are the most well-known stablecoins examples. Gold-backed stablecoins, like PAX gold and Tether Gold, represent the value of one ounce of gold, while crypto-backed stablecoins, like dai, are pegged to the US dollar but are backed by other cryptocurrencies.

Stablecoins not only facilitate the trading of crypto assets on exchanges, but they are also an important bridge between the traditional financial system and the decentralised digital blockchain ecosystem. 

Stablecoins allow traders to transact across various cryptocurrency markets and blockchain applications without having to deal with financial institutions. Following the developments in the decentralised finance sector, using stablecoins for lending and collateralising loans has become increasingly popular. 

The price stability guaranteed by stablecoins makes them a safe haven asset in volatile cryptocurrency markets. Traders and investors use stablecoins to shield themselves from downward market pressures by converting their cryptocurrencies to stable coins to preserve value during market bear cycles.

“Moving into stablecoins allows investors to effectively keep money parked on the sideline without having to completely cash out into fiat currency and incurring fees,” a recent BitStamp and CoinMetrics report observed.

Since stablecoins are designed to maintain their value, they are not considered investment assets but rather facilitators of trade and payment tokens. Market participants can earn returns on their stablecoins by staking them and providing liquidity to various decentralised finance applications across the blockchain.

For example, crypto platforms Nexo and give users 12% interest on staking stablecoins, depending on certain conditions being met. 

Risks involved: tether controversies, transparency issues

The US Department of the Treasury cited numerous risks posed by stablecoins in its latest report, saying:

“An instrument can serve as a reliable means of payment or store of value only when there is confidence in its value, particularly in periods of stress … Confidence in a stablecoin may be undermined by factors, including: (1) use of reserve assets that could fall in price or become illiquid;  (2) a failure to appropriately safeguard reserve assets; (3) a lack of clarity regarding the redemption rights of stablecoin holders; and (4) operational risks related to cybersecurity and the collecting, storing, and safeguarding of data.”

Authorities argue that if the market loses its confidence in the belief that stablecoins are redeemable, fire sales of reserve assets could occur, adversely affecting financial systems and the broader economy.

The US Commodity Futures Trading Commission (CFTC) revealed in October 2021 that tether’s reserves had not been “fully-backed” between 2016 and 2018. As such, the stablecoin had misrepresented itself to the market by claiming it had sufficient US dollar reserves to back every USDT in circulation.

“As found in the order, tether held sufficient fiat reserves in its accounts to back USDT tether tokens in circulation for only 27.6% of the days in a 26-month sample time period from 2016 through 2018,” the CFTC said after it fined tether and Bitfinex $42.5m for misleading statements related to USDT.

In December 2021, tether confirmed that another action had been brought against it, in what it called a “nonsense, copycat lawsuit”.

Looking at stablecoins as a whole, Lark Davis, a cryptocurrency expert, said

“There are some risks investors should be aware of as some stablecoins offer very little in the way of transparency surrounding the assets that they hold in support of their token value.” 

Increasingly wary of the dangers of stablecoins, including their potential use in money laundering and financing terrorism, governments are working to introduce regulatory frameworks to control cryptocurrencies. Authorities across the world have already begun work to create digital currencies backed by central banks. China, having outlawed cryptocurrency transactions and mining in 2021, has taken an early lead with the introduction of its digital yuan

Financial services company Wells Fargo recently voiced the concerns of many in its note to investors: “If the explosive growth that stablecoins have enjoyed in recent years continues in coming years, then periods of financial market volatility could potentially become extreme.” 

“Stablecoin issuers have largely operated in a regulatory vacuum until now. But regulators have become acutely aware of the potential risks that stablecoins present, and they are scrambling to catch up. Some federal agencies have recommended that Congress pass legislation that would require stablecoin issuers to become insured depository institutions, which would be subject to supervision and regulation by the appropriate regulatory bodies,” Wells Fargo said.

Lark Davis is uncertain what a more regulated future would mean for stablecoins. “One wonders if the eventual introduction of the US government-backed digital dollar might be the solution that regulators are really looking for. The big question is whether it would eliminate the need for stablecoins such as tether and USDC. Only time will tell,” he said.

Top stablecoins by market capitalisation

Tether (USDT)

USDT is the most widely used and oldest stablecoin with a market capitalisation equalling nearly 50% of the entire stable coin sector. Overall, USDT is the third biggest  cryptocurrency behind bitcoin (BTC) and ether (ETH) as of 24 January.

“One of the main reasons that Tether has remained so dominant is its superior liquidity compared to other stablecoins,” the Bitstamp and CoinMetrics report states.

After being initially minted on the Bitcoin blockchain, the number one stablecoin launched on the Ethereum blockchain in 2017 and on TRON in 2019. According to Bitstamp, the Ethereum and Tron versions of tether have since surpassed the original version in terms of the total supply.


USD Coin (USDC) is the second biggest stablecoin globally. The founding members of USDC are peer-to-peer payment services company Circle and Nasdaq-listed crypto exchange Coinbase.

USDC differentiates itself from USDT by providing full transparency and publishing attested reports regarding its reserve balances.

“Until July 2021, it was claimed that USDC was backed 1:1 by actual US Dollars in a bank account however this changed to reveal that only approximately 60% of their reserves are held as cash with the remainder being held in short duration US Treasuries,” said Lark Davis in his crypto newsletter.

Currently, USDC smart contracts are available natively on various blockchain networks, including Ethereum, Algorand, Solana, TRON and Stellar, according to its website.

Binance USD (BUSD)

BUSD is the third biggest stablecoin in the world, with a market capitalisation of over $14bn.

The USD-backed stablecoin issued by crypto exchange firm Binance saw strong growth in 2021. The stablecoin grew from a market capitalisation of $1bn at the start of the year to over $14.6bn by the end of 2021, according to CoinMarketCap.

According to its website, “BUSD is a 1:1 USD-backed stablecoin approved by the New York State Department of Financial Services (NYDFS), issued in partnership with Paxos.”

TerraUSD (UST)

TerraUSD occupies the fourth place in the list of stablecoins to watch with a market capitalisation exceeding $11bn (as of 24 January). 

UST is an algorithmic stablecoin of the Terra blockchain. Its value is equal to the face value of minted stablecoins. To issue one TerraUSD, you need to burn one LUNA reserve asset. 

According to the company’s documentation: “[Terra] stablecoins that track the price of fiat currencies. Users mint new Terra by burning Luna. Stablecoins are named for their fiat counterparts. For example, the base Terra stablecoin tracks the price of the IMF’s SDR, named TerraSDR, or SDT. Other stablecoin denominations include TerraUSD or UST, and TerraKRW or KRT. All Terra denominations exist in the same pool.”

Dai (DAI)

MakerDAO is an open-source project on the Ethereum blockchain and is the entity behind the dai stablecoin. According to its white paper, the dai stablecoin is a decentralised, unbiased, collateral-backed cryptocurrency soft-pegged to the US dollar.

On the Oasis Vault portal, users can choose from 25 different cryptocurrencies, including ether, USDC, chainlink and wrapped bitcoin, among others, to deposit as collateral to borrow dai.

As of 24 January, the stablecoin had a market capitalisation of $9.6bn. Note that crypto-backed stablecoins are not as stable as fiat-backed stablecoins due to the higher volatility of the underlying asset.

What does the future of stablecoins hold?

According to the European Central Bank (ECB), “The market capitalisation of stablecoins has risen from $5bn to $120bn since 2020 and they are serving increasingly different functions in the crypto-asset ecosystem … Despite their recent growth, stablecoins still only account for around 6% of the estimated $2tn total market capitalisation of crypto-assets, though interlinkages between stablecoins and crypto assets imply a correlation of risks between these market segments.”

Is there room for further growth? Caitlin Long, founder and CEO of Avanti Financial Group, shared some stablecoin predictions with Cato Journal.

“Stablecoins will grow big enough to start gumming up monetary policy within five or so years, assuming they’re not brought inside the banking system before then …Owing to payment system risk, the cash collateral managers of stablecoin collateral will be mostly non-lending banks,” she said. 

“Consequently, central banks will allow non-lending banks to issue stablecoin‐​like instruments,” she added.

Viktor Prokopenya, the founder of, also believes stablecoins could be an opportunity for some banks. 

“If a major bank were to launch their own coin, this would undoubtedly generate a lot of positive traction,” he said in an interview with Justin Pugsley. But he warned there could still be the issue that it would connect the bank to the world of cryptocurrencies, which remains underregulated. 

According to the US’s President’s Working Group on Financial Markets (PWG) report: “Beyond digital asset trading, several existing stablecoin issuers and entities with stablecoin projects under development have the stated ambition for the stablecoins they create to be used widely by retail users to pay for goods and services, by corporations in the context of supply chain payments, and in the context of international remittances. 
“The extent to which stablecoins will be used for these purposes is difficult to predict and is likely to depend on the convenience of service options, the competitiveness of stablecoin transaction costs, and users’ confidence in the stablecoin issuer, including confidence in the issuer’s ability to maintain a stable value and facilitate redemption. However, the transition to more widespread use could occur quickly – for example, due to network effects or the ability of stablecoins to expand through relationships with existing user bases or platforms.”

If you’re exploring stablecoins or any crypto assets, it’s always important to do your own research. Consider the latest market trends, a projects’ fundamentals and expert opinion before making your list of best stablecoins to invest in. Keep in mind that trading any crypto assets, including stablecoins, is risky. And never invest more than you can afford to lose.


Are stablecoins safe?

Unlike other cryptocurrencies that operate in a decentralised environment, stablecoins are overseen by a central authority to maintain value and provide liquidity. Considered safe-haven crypto assets, they still contain risks due to their less volatile nature. You should always perform your own due diligence of any stablecoin and the project behind it to build your own view.

Is bitcoin stable?

Bitcoin is not a stablecoin and is not backed by an underlying asset. Bitcoin’s price movement is known to be highly volatile.

The difference between trading assets and CFDs
The main difference between CFD trading and trading assets, such as commodities and stocks, is that you don’t own the underlying asset when you trade on a CFD.
You can still benefit if the market moves in your favour, or make a loss if it moves against you. However, with traditional trading you enter a contract to exchange the legal ownership of the individual shares or the commodities for money, and you own this until you sell it again.
CFDs are leveraged products, which means that you only need to deposit a percentage of the full value of the CFD trade in order to open a position. But with traditional trading, you buy the assets for the full amount. In the UK, there is no stamp duty on CFD trading, but there is when you buy stocks, for example.
CFDs attract overnight costs to hold the trades (unless you use 1-1 leverage), which makes them more suited to short-term trading opportunities. Stocks and commodities are more normally bought and held for longer. You might also pay a broker commission or fees when buying and selling assets direct and you’d need somewhere to store them safely.
