Stablecoin

A token built to stand still

Most cryptocurrencies float freely and swing hard. A stablecoin takes the opposite goal: each token should always be worth the same amount, almost always one US dollar. The dominant design is reserve-backed: for every token issued, the issuer holds a matching dollar of assets, typically cash and short-term US government debt, and stands ready to redeem tokens at par.

A second design, the algorithmic stablecoin, tried to hold its peg with trading incentives and no full reserves. The largest experiment of that kind collapsed, and the design is now widely treated as discredited. When people say stablecoin today, they almost always mean the reserve-backed kind.

What they are actually for

Inside crypto markets, stablecoins are the cash drawer: traders park value between positions, move dollars between platforms in minutes, and price other tokens against them. Outside trading, they are used for cross-border transfers, and payment companies have run experiments with them as settlement rails.

For most Canadians the practical encounter is simpler: sell a cryptocurrency during volatile markets and the proceeds often land in a stablecoin first, before being converted to dollars in a bank account.

The promise is only as good as the reserves

A stablecoin is an IOU. Whether it actually holds its dollar depends on what sits in the reserves, how often they are verified, and whether you have a real right to redeem. Those three things vary meaningfully between issuers, and the details live in attestations most holders never read.

Pegs have broken before, temporarily for well-backed coins during panics and permanently for weaker designs. And unlike a bank deposit, no stablecoin carries deposit insurance: CDIC protects Canadian bank deposits, and nothing equivalent stands behind any token.

The Canadian angles: regulation, currency and tax

Canadian securities regulators impose conditions on the trading platforms that list stablecoins, including standards for reserves and disclosure, and the set of coins available to Canadians reflects that gatekeeping. A small Canadian-dollar stablecoin market exists, but the overwhelming majority of stablecoin value is pegged to the US dollar.

That creates a quiet exchange-rate exposure: holding a USD stablecoin is holding US dollars, so its value in Canadian dollars moves with the loonie even while the peg holds perfectly. See currency risk for how that cuts both ways.

On tax, one fact matters more than any other: the CRA treats stablecoins like any other crypto asset, so trading a cryptocurrency into a stablecoin is a disposal and can trigger a taxable gain or loss, exactly as if you had sold for cash. Parking profits in a stablecoin does not defer anything.
