Algorithmic Stablecoins: What They Are and Why They Are Being Banned

Algorithmic Stablecoins: What They Are and Why They Are Being Banned

Algorithmic stablecoins hold their dollar peg not through reserves but through smart contract rules and incentives for arbitrageurs. While the market is calm, the scheme works, but in a panic it can collapse within a few days.

Let's look at how they are built, why they break and why regulators ban them. A recent example of a ban is Nigeria's rules, which took effect on November 5, 2026.

What an algorithmic stablecoin is

It is a token that aims to be worth one dollar but does not hold a dollar for every coin. The peg is maintained by a minting and burning mechanism.

There are usually two tokens in the scheme. The first is the stablecoin itself, and the second is the system's volatile token, which absorbs swings in demand.

How algorithmic stablecoins differ from fiat-backed and crypto-backed ones

In our view, the difference comes down to one question: what do you get when you redeem.

A fiat-backed token has reserves. An algorithmic one has nothing behind the coin except the protocol's promise to give you a dollar's worth of the second token at its current market price.

How the peg works: mint, burn and arbitrage

The mechanism guarantees a one-to-one exchange in dollar terms. One stablecoin can always be burned for one dollar's worth of the second token, and vice versa.

• the stablecoin trades above a dollar: an arbitrageur burns a dollar's worth of the second token, gets a stablecoin and sells it higher
• the stablecoin trades below a dollar: an arbitrageur buys it on the market, burns it and receives a full dollar's worth of the second token
• in both cases the trade pulls the price back to a dollar

So it is the traders themselves who hold the peg. The protocol simply pays them for correcting the deviation.

Why algorithmic stablecoins break

The weak spot is the second token. When the stablecoin loses its peg, arbitrageurs burn it and receive more and more of the second token.

Its supply grows and its price falls. To hand out a dollar's worth of value, the protocol has to print even more tokens, and so on in a loop.

This is what is called a death spiral. The mechanism that is supposed to save the peg accelerates the fall in a panic.

The best-known example is Terra. In May 2022 its stablecoin UST lost its dollar peg, the LUNA token became almost worthless within days, and the entire ecosystem collapsed with it.

Why regulators ban algorithmic stablecoins

A regulator sees a stablecoin as a promise to return money. The algorithmic model has no reserves that can be verified, which means there is no guarantee of redemption in a crisis.

We believe that after the Terra collapse many regulators took a clear-cut approach. The Central Bank of Nigeria's rules, which took effect on November 5, 2026, explicitly ban algorithmic stablecoins and require the reserves of each token to be approved before issuance.

How arbitrageurs trade a stablecoin depeg and why it is dangerous

A depeg looks like a gift: the token costs $0.97, and the mechanism promises to exchange it for a dollar. But the profit comes in the second token, which still has to be sold.

A hypothetical example. A trader buys 10,000 stablecoins at $0.97 for $9,700 and swaps them for $10,000 worth of the second token at the current price.

While they are selling those tokens, the price drops 4%. In the end they hold $9,600 and a hypothetical loss of $100 instead of the expected $300 profit.

• check how much of the second token can be sold without heavy slippage
• look at minting limits and redemption queues in the protocol
• do not go in with a large size during the first hours of a panic
• keep in mind that exchanges may halt withdrawals or trading in the token

From what we see, a depeg of a reliable fiat-backed stablecoin and a depeg of an algorithmic one should be assessed differently. In the first case there are reserves behind the coin; in the second, catching a falling token is far more dangerous.

Our tools

A stablecoin depeg shows up with different depth on different exchanges, and prices are easier to compare when all the venues are gathered in one window. Our arbitrage screener keeps dozens of venues in one window, refreshes quotes every second and shows each gap together with the volume actually behind it. The spread calculator helps you check what survives fees, network costs and slippage at your size. The bot is fully manual. It never connects to your exchange API keys.

To test the tools on a live market, ArbitrageScanner offers one day of free access to the whole ecosystem.

FAQ (Frequently Asked Questions)

1. What is an algorithmic stablecoin in plain words?

A token that holds its dollar peg not with reserves but with smart contract rules: minting and burning paired with a second, volatile token.

2. How does an algorithmic stablecoin differ from USDT and USDC?

Fiat-backed stablecoins are backed by the issuer's reserves. Behind an algorithmic one there is only a mechanism for swapping it into the protocol's second token.

3. What is a stablecoin death spiral?

A situation where, after the peg breaks, the protocol prints more and more of the second token, its price falls, and the stablecoin drops even lower.

4. Why did UST collapse?

In May 2022 UST lost its peg, mass swaps into LUNA crashed its price almost to zero, and the peg mechanism stopped working.

5. Where are algorithmic stablecoins banned?

A recent example is Nigeria: the Central Bank's rules, which took effect on November 5, 2026, explicitly ban them.

6. Can you profit from a stablecoin depeg?

Arbitrageurs try, but with algorithmic tokens the risk is high: the profit comes in the second token, whose price may fall faster than you can sell it.

Conclusion

Algorithmic stablecoins hold their peg through minting, burning and arbitrageurs rather than reserves. In a calm market this works, but in a panic the mechanism fuels a death spiral, as happened with Terra in May 2022.

That is why regulators, including the Central Bank of Nigeria, ban such tokens. In a depeg, an arbitrageur should count not the promised dollar but the price at which the second token can actually be sold.
