Stablecoins are becoming increasingly popular, with their market cap reaching $10 billion for the first time in May 2020. But how are they different from other cryptocurrencies? And are they a good investment? Let’s explore more on what it is.
Stablecoins are cryptocurrencies that have their price pegged to or backed by a stable asset, or group of assets. Most are pegged to fiat i.e. real currency. However, some may be pegged to the price of commodities such as gold, or even other cryptocurrencies. Some are not pegged to any asset.
Many see stablecoins as having the best of both worlds – they possess the blockchain technology that most cryptocurrencies possess, but are without the volatility that Bitcoin and other cryptocurrencies can suffer from. They are stable coins in the literal sense of the word.
How do stablecoins work so they are actually kept stable?
Price stability and low volatility are often cited as major advantages of stablecoins. It should be noted however that stablecoins are only as stable as the asset they are pegged to.
Although by their nature, stablecoins are pegged to assets which are expected to be stable themselves, that’s not to say they are not immune to volatility.
Price swings could still happen, thus affecting the volatility of the stablecoin. Thankfully, this is rare. Stablecoins are generally very stable because of the high stability of the asset they are pegged to.
But how are stablecoins kept stable, or in other words, how do they keep their peg maintained?
This comes down to the issue of trust. For the peg to be maintained, the market needs to have trust in the asset the coin is pegged to. That’s why coins are pegged to trusted assets such as US dollars, gold and oil.
Tether (USDT), for example, is pegged to the US dollar, meaning that for every unit of USDT, parent company Tether keeps a US dollar in reserves. If the market didn’t hold trust in that one unit of USDT was worth one dollar, then it would crash. However, the fact that USDT for the most part has been always very close to one dollar in value, is a testament to the trust the market has in it.
Price stability and low volatility can bring convenience, but in what ways are stablecoins used?
Stablecoins are being increasingly used for transactions, with the blockchain technology enabling international transactions to be done significantly more quickly than more traditional means. Additionally, some individuals and merchants may be perhaps understandably resistant to transact in a cryptocurrency which may fluctuate in price massively in a short period of time, such as Bitcoin. With stablecoins, this risk is significantly lower.
Also in developing countries, they are starting to be used as an alternative to the failing bank systems where many don’t have a bank account at all and hyperinflation can be a huge problem. The stablecoin project Reserve was launched in Venezuela and Angola in 2019 in an attempt to combat these issues.
Let’s imagine a trader is concerned about the risk of the price of Bitcoin falling against the US dollar. They may not want to exchange to fiat, as this can be expensive due to processing fees. So, that’s where exchanging to a stablecoin can be a handy option. They could be exchanged to a stablecoin pegged to the price of the US dollar, such as USDT, and this risk is then taken away. You can do this on Bybit using our Asset Exchange feature, where for just a 0.1% fixed fee, you can swap to USDT from any of our other tradeable cryptocurrencies – BTC, ETH, EOS, and XRP. Bybit is the only cryptocurrency derivatives exchange to offer this feature.
DeFi in recent years has become well-established in the financial sector, and offers a public blockchain based alternative to traditional financial services through the use of smart contracts. Stablecoins play their part as they offer a stable means of transactions taking place in the DeFi system.
Four different types of stablecoins exist. Three types are backed by collateral, and one type is not. In addition to this, two types are centralized (held by a central entity), and two types are decentralized (not held by a central entity).
Most stablecoins are pegged to fiat currencies, such as USD, EUR or GBP. This is done at, or very near to, a 1:1 ratio. This essentially means that for every stablecoin, there is a unit of fiat currency stored somewhere in reserves too.
So let’s imagine that somebody wants to convert their stablecoins into cash. The institution storing the stablecoins will send the fiat currency being stored in reserves to the individual’s bank account, and the amount of stablecoins equating to the amount of fiat circulation will be removed from circulation.
Most stablecoins in this category are collateralized to gold, but they can be collateralized to other commodities too, including metals, oil, or real estate. These commodities act as mechanisms to limit price volatility. Commodity backed stablecoins can give everyday investors the opportunity to invest in commodities. Although investments in assets such as gold have traditionally been for the rich, these types of stablecoins have opened them up to potentially a whole new demographic of people.
Some stablecoins are pegged to cryptocurrencies. In contrast to fiat-backed stablecoins, cryptocurrency backed stablecoins are issued through smart contracts. As cryptocurrency prices can be notoriously volatile, coins are often backed by multiple cryptocurrencies. So if one suffers price volatility, the others can absorb the shock while remaining stable.
Additionally, some are protected by a process called over-collateralization. It means when the coin is backed by an asset more than the value of the coin, and is used as a protective measure. So, instead of a ratio 1:1 like fiat, the ratio may be 1:2 instead, meaning that the stablecoin is backed up by cryptocurrency collateral double its value.
Believe it or not, non collateralized stablecoins do exist. The supply of these stablecoins is controlled by algorithmic pegging and smart contracts. Supply and demand drives the prices of these stablecoins. The supply of these stablecoins is controlled by an algorithm-based model known as seigniorage shares.
If the price of the stablecoin increases, then coins will be issued by the algorithm until the supply and demand achieve equilibrium. If the price of the stablecoin decreases, then the supply of the coins will be reduced until supply and demand also achieves equilibrium. By doing these things, the algorithm can keep the price of the coin stable.
By some estimates there are now over 200 types of stablecoin. Let’s look at some of the most popular ones out there.
Tether (USDT) is a fiat-backed stablecoin and is the biggest stablecoin by market capitalization. Pegged to the US dollar at a 1:1 ratio, USDT was created in 2014. It overtook Bitcoin as the most traded cryptocurrency by market volume in 2019. USDT is issued on seven blockchains, including Ethereum.
USD Coin (USDC) is pegged to the US dollar. Launched in 2018 as a joint venture between Circle and Coinbase, USDC is a ‘digital dollar’ that can be used for crypto-based transactions. It is an Ethereum (ERC-20) token. According to Circle, an audit of the US dollar reserves is done every month.
TrueUSD (TUSD) is a fiat-backed stablecoin pegged to the US dollar, founded in 2018. Rather than the US dollar reserves being held by a sole entity (such as with USDT), they are held in multiple escrowed bank accounts. According to distributor Trusttoken, this is done for transparency.
Dai (DAI) is ‘soft pegged’ to the US dollar in that it is not issued by a central entity. Instead decentralized token holders govern the Maker Protocol. Through smart contracts, this protocol pegs the coin to the US dollar. It is an emerging cryptocurrency in DeFi and is backed by Ethereum.
Paxos Standard (PAX) is a fiat-backed stablecoin pegged to the US dollar, launched in 2018. Today, PAX’s functions include to limit crypto-asset volatility and to remove cross-border transaction fees, but it is hoped by its issuer Paxos Trust Company to be used for consumer payments in the future.
Digix Gold (DGX) is pegged to gold, with one unit of the currency equal to one gram of gold. The gold is stored in a vault, and holders of the currency may redeem gold bars if they visit the vault themselves. The gold is audited every three months to ensure the full amount is still being held.
Binance USD (BUSD) is a dollar-backed stablecoin, launched in 2019. It is the result of a partnership between Binance and Paxos. To date, it is only one of a handful of stablecoins approved by US regulatory authorities. Its supply is regularly externally audited to maintain trust with its users.
One of the most controversial cryptocurrencies of all time is the planned Libra coin from Facebook. The original whitepaper was released in June 2019, with its stated mission to “become a simple global currency and financial infrastructure that empowers billions of people”. Its original vision was it for to be a multi-currency stablecoin backed by a basket of around 30 fiat currencies. But this changed when pressure mounted over regulatory concerns, with several backers pulling out such as Visa and Mastercard. In response, Libra 2.0 was released in April 2020, with one of the key changes being single-currency stablecoins in addition to the multi-currency coin. However, with regulatory concerns still lingering, its future is unclear.
There are contrasting options on whether stablecoins are a good investment or not. Let’s look at some of the arguments for and against.
Although the question of if stablecoins are a good investment is open to debate, what isn’t is that they have much potential. They bring the benefits of blockchain technology and stability, meaning they can be relied upon for transactions in the crypto ecosystem. Their mass adoption has the potential to revolutionise traditional means of financial transactions and provide a much needed avenue for the 1.7 billion unbanked (those without a bank account) around the world. They could prove to be a safe haven from the hyperinflation which plagues some third world countries. The future is bright for stablecoins.
