Stablecoins are a type of cryptocurrency designed to have a stable value relative to a specific asset or a basket of assets, typically a fiat currency such as the U.S. dollar, euro or Japanese yen.
Stablecoins are designed to offer a “stable” store of value and medium of exchange compared with more traditional cryptocurrencies like Bitcoin (BTC) and Ether (ETH), which can be highly volatile.
Fiat money, cryptocurrencies, and commodities like gold and silver are examples of assets used to collateralize or “back” stablecoins. Tether (USDT), USD Coin (USDC) and Dai (DAI) are a few examples of stablecoins pegged to the U.S. dollar.
Stablecoins can also be algorithmically stabilized through smart contracts and other mechanisms that automatically adjust the supply of the stablecoin to maintain its peg to the underlying asset.
Despite the potential benefits, stablecoins are not without risks. The most significant risk with any stablecoin is the potential for its peg to break, causing it to lose its value relative to the underlying asset.
Depegging is where the value of a stablecoin deviates significantly from its pegged value. This can happen for various reasons, including market conditions, liquidity issues and regulatory changes.
USDC is a fully reserved-backed stablecoin, meaning every USD Coin is backed by actual cash and short-dated United States treasuries. Despite this, USDC issuers, Circle, announced on March 10 that USDC had depegged from the U.S. dollar, with around $3.3 billion of its $40 billion in USDC reserves stuck in the now defunct Silicon Valley Bank. The bank — the 16th-largest in the U.S. — collapsed on March 10, and is one of the biggest bank failures in U.S. history. Given USDC’s collateral influence, other stablecoins followed suit in depegging from the U.S. dollar.

2/ Like other customers and depositors who relied on SVB for banking services, Circle joins calls for continuity of this important bank in the U.S. economy and will follow guidance provided by state and Federal regulators.

MakerDAO — a protocol based on the Ethereum blockchain — issues DAI, an algorithmic stablecoin designed to preserve a precise 1:1 ratio with the U.S. dollar. However, DAI also fell off its peg amid the Silicon Valley Bank’s collapse, mainly due to a contagion effect from USDC’s depegging. Over 50% of the reserves backing DAI are held in USDC.
Tether issues USDT, with every USDT token equivalent to a corresponding fiat currency at a 1:1 ratio and fully backed by Tether’s reserves. However, USDT also experienced a depegging in 2018, which raises concerns about the overall stability mechanism of stablecoins.
Importance of stablecoin pegs
The importance of stablecoin pegs is in providing a stable and predictable value relative to an underlying asset or basket of assets — typically a fiat currency like the U.S. dollar. Stablecoins are a desirable alternative for various use cases, including cryptocurrency trading, payments and remittances, due to their stability and predictability.
With stablecoin pegs, traders may enter and exit positions without being subjected to the price fluctuations of cryptocurrencies like BTC or ETH. This is important for institutional investors and companies that depend on a reliable store of value and a medium of exchange to run their operations.
Cross-border transactions can also be made more accessible using stablecoin pegs, especially in nations with volatile currencies or restricted access to conventional financial services. Compared with more traditional methods like wire transfers or remittance services, stablecoins can offer a more effective and affordable way to make payments and transfer value across borders.
Stablecoin pegs can also increase financial inclusion, especially for people and enterprises without access to traditional financial services. Stablecoins can be used to make payments and transact in digital assets without requiring a bank account or credit card, which can be crucial in developing and emerging markets.
Why do stablecoins depeg?
Stablecoins can depeg due to a combination of micro and macroeconomic factors. Micro factors include shifts in market conditions, such as an abrupt increase or decrease in stablecoin demand, problems with liquidity and modifications to the underlying collateral. Macro variables involve changes in the overall economic landscape, such as inflation or interest rate increases.
For instance, a stablecoin’s price can momentarily exceed its pegged value if demand spikes due to increased cryptocurrency trading activity. Yet, the stablecoin’s price could drop below its fixed value if insufficient liquidity matches heightened demand.
On the macroeconomic front, if there is high inflation, the purchasing power of the underlying assets that support the stablecoin may drop, leading to a depeg event. Similarly,…
