Trail notes
- A stablecoin is a token designed to track the value of something else, usually one US or Canadian dollar.
- There are three broad designs: backed by cash-like reserves, backed by other crypto, or held steady by an algorithm.
- Pegs hold when people can redeem or arbitrage at the target price, and break when that promise stops being believable.
- As of 2026-10-30, Canada’s Stablecoin Act is enacted but not in force; Finance Canada expects the framework to apply in 2027.
- Stablecoins are not deposits. CDIC does not cover them.
What a stablecoin is trying to do
Most crypto-assets move in price all day. That makes them awkward for paying, saving or measuring anything. A stablecoin is a token built to hold a steady value against a reference, most often one US dollar, sometimes a Canadian dollar, a basket or a commodity. The target value is called the peg.
Stablecoins matter in DeFi because they are the unit almost everything else is priced in. You borrow stablecoins against collateral, you pair them with other tokens in liquidity pools, and you park in them between trades. When a stablecoin wobbles, everything built on top of it wobbles too.
The important word is “designed”. A stablecoin is not a dollar. It is a promise, plus a mechanism, that tries to keep the token close to a dollar. Your job as a reader is to understand which promise and which mechanism you are relying on.
Three designs: reserves, crypto collateral and algorithms
Educational sources such as ethereum.org group stablecoins into three broad families. Real tokens can blend features, but these categories help you ask the right questions.
| Design | What backs it | How the peg is defended | Main weak point |
|---|---|---|---|
| Fiat-backed | Cash, bank deposits or short-term government debt held by an issuer | Holders (often only approved ones) can redeem one token for one unit of currency | Trust in the issuer, its custodians and its reserve reporting |
| Crypto-collateralized | Other crypto-assets locked in smart contracts, worth more than the tokens issued | Over-collateralization plus automatic liquidations when collateral falls | Sharp market crashes, oracle failures and smart contract bugs |
| Algorithmic | Little or no outside collateral; supply rules and incentives | Minting and burning tokens, often against a companion token | Confidence: if demand collapses, the mechanism can spiral |
Fiat-backed stablecoins are the easiest to picture. An issuer receives a dollar, issues a token, and holds the dollar (or something close to it) in reserve. USDC is an example of this design. The risk is not code so much as the issuer: are the reserves really there, are they liquid, and can you or an intermediary actually redeem?
Crypto-collateralized stablecoins replace the issuer with smart contracts. You lock, say, the equivalent of 150 dollars of a volatile token to mint 100 dollars of stablecoin. If your collateral falls too far, the system sells it to keep the stablecoin backed. This is the same mechanic described in our lending protocols guide.
Algorithmic stablecoins try to hold the peg by expanding and shrinking supply. They can work while demand is steady and fail quickly when it is not.

How a peg holds: redemption and arbitrage
Pegs are held by people who profit from closing the gap. If a token trades below the target, someone buys it cheaply and redeems it, or repays debt with it, at full value. If it trades above, someone mints new tokens at the target and sells them. That buying and selling is called arbitrage, and it pulls the market price back toward the peg.
Notice what the example depends on: redemption that actually works, at the promised price, quickly enough to be worth it. Every design has its own version of that dependency. For crypto-collateralized coins, it is liquidations that clear in time. For algorithmic coins, it is people continuing to want the companion token.
How pegs break
A depeg is when a stablecoin trades meaningfully away from its target. Some depegs last minutes. Others are permanent. Common causes include:
- Reserve doubts: news or rumours that reserves are short, frozen at a bank or hard to sell.
- Redemption friction: redemptions paused, limited to large institutions, or slowed by banking hours.
- Collateral crashes: crypto collateral falls faster than liquidations can sell it.
- Oracle or code failures: a wrong price feed or a bug lets bad debt build up. See oracle manipulation.
- Loss of confidence: for algorithmic designs, selling pressure feeds itself until the mechanism stops working.
The TerraUSD (UST) algorithmic stablecoin lost its peg in May 2022. It is the clearest example of why “stable” describes a goal, not a guarantee. Our page on stablecoin depeg risk walks through what a depeg can do to a position.
A depeg also spreads. Lending markets that accept the stablecoin as collateral can see sudden liquidations, and liquidity pools that pair it with another stablecoin can end up holding mostly the weaker coin.
Stablecoins in Canada: platform terms and the Stablecoin Act
Two separate tracks apply in Canada, and it helps to keep them apart.
Securities regulators and trading platforms. The Canadian Securities Administrators (CSA) treat stablecoins as value-referenced crypto assets (VRCAs). CSA Staff Notice 21-333 (release dated 2023-10-05) set interim terms for VRCAs offered on registered or pre-registered platforms, including a reserve held with a qualified custodian for holders and public disclosure about the reserve and operations. A CSA update dated 2024-09-26 said that after 2024-12-31, platforms may only offer VRCAs that meet the terms of their decisions or undertakings, and warned that VRCAs do not carry the protections of regulated deposits.
Federal stablecoin legislation. The Stablecoin Act was enacted through Bill C-15, which received Royal Assent on 2026-03-26. As of the Justice Laws consolidation current to 2026-09-30, the Act is marked “not in force”; it comes into force on a day fixed by order. Finance Canada’s framework page (modified 2026-03-31) describes 1:1 reserves of high-quality liquid assets, redemption at par, no interest or yield paid by issuers, and Bank of Canada supervision, and says the framework is expected to come into force in 2027. Proposed Stablecoin Regulations were published for consultation in the Canada Gazette, Part I, on 2026-10-24.
The Stablecoin Act is law on paper but not yet in force, and its regulations are proposed, not final. Stablecoins are not covered by CDIC: its “What’s covered” page lists cryptocurrencies, including stablecoins, as not eligible. See the Stablecoin Act page and CDIC and crypto for more.
How to check a stablecoin before you hold it
You do not need to pick a favourite. You need to know what you are holding and what could make it slip.
- Identify the design: reserves, crypto collateral or algorithm.
- For reserve-backed coins, read who holds the reserves, what they are made of and how often reports are published.
- Ask who can redeem, at what minimum size and how quickly. If you cannot redeem, you depend on someone who can.
- Check that the token contract address matches the one the issuer publishes; copycat tokens are common.
- Think about where you hold it: a platform’s account, your own wallet or inside a DeFi protocol each add their own risk.
- Compare it honestly with insured alternatives. Our stablecoin types comparison and DeFi vs GIC page can help.
None of this predicts the future. It just helps you see the shape of the promise, so a wobble does not catch you completely off guard.

Questions people ask
Are stablecoins safe?
No. Every stablecoin carries risk, because each depends on something, such as an issuer’s reserves, crypto collateral and liquidations, or an algorithm and market confidence, and any of those can fail and cause a depeg.
Are stablecoins covered by CDIC in Canada?
No. CDIC’s “What’s covered” page lists cryptocurrencies, including stablecoins, as not eligible for deposit insurance, and the CSA has warned that stablecoins do not carry the protections of regulated deposits.
Is the Stablecoin Act in force?
Not yet. As of 2026-10-30 the Stablecoin Act has been enacted (Royal Assent 2026-03-26) but is marked not in force, proposed regulations were published on 2026-10-24, and Finance Canada expects the framework to come into force in 2027.
What is a VRCA?
VRCA stands for value-referenced crypto asset, the term the Canadian Securities Administrators use for stablecoins. Platforms serving Canadians may only offer VRCAs that meet the terms set in their regulatory decisions or undertakings.
Why do stablecoins lose their peg?
A peg breaks when the mechanism that defends it stops being trusted or stops working, for example doubts about reserves, paused redemptions, collateral falling faster than liquidations, a faulty price feed, or a collapse in demand for an algorithmic design.
