Cryptocurrencies are known for wild price swings, so the idea of a "stable" coin can sound like a contradiction. Yet stablecoins have become a widely used part of the crypto world, bringing traditional assets into blockchain technology.
This guide explains what a stablecoin is, how it holds its value, the main types, and what people use them for. It also weighs the pros and cons, including the risks around de-pegging, reserves, and the lack of deposit insurance. Finally, it looks at how stablecoins are treated in Canada, where the rules are still taking shape.
What is a stablecoin?
A stablecoin is a type of cryptocurrency designed to hold a steady value, usually by tracking a reserve asset such as a national currency or a commodity like gold. That single feature sets stablecoins apart from crypto assets whose prices swing sharply with supply and demand. The idea is to combine the speed and reach of a blockchain with price predictability.
Most stablecoins in circulation track a major fiat currency. A smaller share is pegged to other currencies or to commodities such as gold. Some are even denominated in Canadian dollars, though those remain a niche part of the market.
It's important to remember that although the term "stablecoin" is commonly used, there is no guarantee that the asset will maintain a stable value in relation to the value of the reference asset when traded on secondary markets or that the reserve of assets, if there is one, will be adequate to satisfy all redemptions.
How do stablecoins stay stable?
The word "stable" refers to the peg — the fixed value a coin is meant to maintain, often one-to-one with the asset behind it. A stablecoin usually passes through a few stages before anyone can use it. A token is issued, recorded on a blockchain, and stored in a digital wallet. A blockchain is simply a shared digital ledger that tracks ownership and transactions.
The value of each token is linked to the reserves held to support it. In principle, a holder can redeem a token for the underlying asset, such as cash. Some stablecoins allow users to redeem their stablecoin directly with the issuer, on publicly disclosed terms and conditions. Other stablecoins may not have a direct redemption right against the issuer, and holders of those stablecoins are limited to buying and selling those stablecoins from crypto trading platforms or decentralized exchanges, where the price of the stablecoin may fluctuate. The redeemability of a stablecoin is what keeps the peg intact. If a token can always be exchanged for the asset behind it, its market price tends to stay close to that value. If confidence is lost in the ability for the reserve assets to maintain the peg, the value of a stablecoin may stop tracking the peg.
Types of stablecoins
Stablecoins are generally grouped by what backs them. Each design manages the peg differently, with its own trade-offs.
Fiat-backed stablecoins
Fiat-backed means that the crypto asset is 'pegged' to the value of a specific traditional currency. Each token is backed by cash or short-term government debt held in reserve, usually at a one-to-one ratio. This is a common design, and its reliability depends on the quality of the reserves and regular, credible reporting on them.
Crypto-backed stablecoins
Reserves are held in other crypto assets locked in smart contracts. That collateral can be volatile, so these coins are typically over-collateralized. In other words, the reserves are worth more than the coins issued, which helps absorb price swings.
Commodity-backed stablecoins
The token tracks a physical asset such as gold, with the reserve held to support redemptions. These give exposure to a commodity in digital form.
Algorithmic stablecoins
No hard collateral backs the coin. Instead, software rules adjust the supply of the token to defend the peg. This design tends to be especially fragile, and an algorithmic peg can fail when confidence drops.
What are stablecoins used for?
Stablecoins are mainly a way to move value quickly and at low cost. Common uses include the following:
Trading: moving between crypto assets without converting back to cash each time.
Payments and transfers: near-instant settlement, often with much lower fees than some traditional cross-border options.
Cross-border remittances: sending money internationally without the delays and costs of conventional transfer rails.
Holding value: in economies with high inflation, people use fiat-pegged coins to hold a steadier store of value.
Pros of stablecoins
Price stability: holds a predictable value compared with other crypto assets.
Speed and low cost: settles transfers in minutes, at times more cheaply than traditional payment rails.
Accessibility: reaches anyone with an internet connection and a wallet, without a traditional bank account.
Transparency: records transactions on a public ledger, with reputable issuers publishing information about their reserves.
Cons and risks of stablecoins
A stablecoin is only as reliable as the reserves and the issuer behind it. The main risks affect how a stablecoin functions and how dependable its value may be.
De-pegging risk
If holders lose confidence that a token can be redeemed at full value, the peg can break. A de-pegged coin trades below its target price, and in stressed conditions that gap can widen quickly.
Reserve and issuer risk
Fiat-backed coins depend on the quality of their reserves and the trustworthiness of the issuer. If reserves are inadequate, poorly managed, or held at a troubled institution, the coin's value can come under pressure. Crypto-backed and algorithmic designs carry their own version of this risk.
No deposit insurance
A stablecoin is not the same as, and is riskier than, a deposit in a bank or cash held with a platform, and it is not covered by federal deposit insurance. In Canada, eligible deposits at member institutions are protected by the Canada Deposit Insurance Corporation (CDIC). Crypto assets, including stablecoins, fall outside that protection. If an issuer, or the custodian holding the reserve assets on behalf of the issuer, fails, holders are not guaranteed to recover their money.
Stablecoins in Canada
Regulation is catching up with the market. Canadian securities regulators have treated stablecoins as a distinct category of crypto asset under an interim approach. Separately, a federal framework for stablecoins has been enacted through the Stablecoin Act (Bill C-15, which received Royal Assent in March 2026), setting expectations around issuer registration, reserve requirements, and Bank of Canada oversight. It is not yet fully in force, with supporting regulations expected to bring it into force in 2027.
The Financial Consumer Agency of Canada (FCAC) has also studied consumer awareness, use, and understanding of stablecoins. That work reflects a broader focus on protecting Canadians as the market develops. Rules continue to evolve, so the regulatory picture is likely to keep changing.
