The mint and redeem arbitrage loop that restores stablecoin pegs
Stablecoins are designed to trade at $1. They rarely sit exactly at that price. The mechanism that pushes them back is an arbitrage loop involving minting and redemption, and anyone can exploit the difference between the market price and the par value.
When a stablecoin trades above $1, say at $1.01, an arbitrageur can mint one new token from the issuer. That token costs $1. The arbitrageur sells it on the open market for $1.01. Profit is $0.01 per token, and the selling pressure pushes the market price down toward $1.
When the stablecoin trades below $1, the same logic works in reverse. Buy one token cheaply on the market, say for $0.99, then redeem it with the issuer for $1. Profit is again $0.01 per token, and the buying pressure lifts the price back toward $1.
This is the core loop. It works only if the issuer allows minting and redemption at par, without friction, and without delay. Curve’s 3pool and stableswap invariants are the venues where this arbitrage plays out most efficiently. The 3pool holds DAI, USDC, and USDT, while the stableswap invariant keeps the pool balanced so that large trades shift price only slightly. Arbitrageurs monitor these pools constantly. When a peg drifts, they act in seconds.
What Blocks Arbitrage
The loop can fail. Three common barriers stop arbitrageurs from restoring the peg.
Mint caps. Some issuers limit how many tokens can be minted in a given period. If the cap is reached, no new tokens can be created at par, and the price can stay above $1 until the cap resets.
Redemption pauses. Issuers sometimes pause redemptions entirely. This might happen during a bank run or a technical issue. If redemptions are paused, the arbitrageur who bought cheap tokens cannot redeem them, so the price can stay below $1 indefinitely.
Oracle staleness. Some stablecoins rely on oracles to determine the redemption price. If the oracle price is stale or manipulated, the arbitrageur may not know the true par value, and the loop becomes blind.
These barriers are not hypothetical. They have occurred repeatedly in stablecoin history.
Decision Framework for a Mild Depeg
Suppose a stablecoin trades at $0.97 and you hold it. Do you exit or wait for arbitrageurs?
First, check whether the issuer allows redemptions. If redemptions are open, the arbitrage loop should eventually work. The price might drift lower in the short term, but the incentive to buy and redeem is obvious, and large players will act. History suggests most mild depegs resolve within hours when redemptions are functional.
If redemptions are paused, the loop is broken. There is no guarantee of restoration, the price could fall further, and exiting may be the safer move.
Second, check the depth of the secondary market. If liquidity is thin, even small redemption pressure can move price, but thin liquidity can also mean the price recovers fast once redemptions reopen. Low volume amplifies both directions.
Third, check the nature of the depeg. A mild depeg caused by a temporary imbalance - large sell order, market panic - tends to reverse. A depeg caused by a structural problem - insolvency, regulatory action - may not reverse.
As of August 31, 2026, BabyKitty (BABYKITTY) trades at approximately $0.00000000000000000003226. Its market cap is $127,638. Volume in the last 24 hours was $56.06, with seven transactions. The pair launched on December 22, 2021, on PancakeSwap. It has two pairs. Liquidity is $118,158.79. The token is not listed on CoinGecko. No whitepaper exists. No GitHub repository is public.
These facts describe a token with negligible trading activity. The arbitrage loop described above assumes a functioning stablecoin issuer with open minting and redemption. BabyKitty is not a stablecoin. The mechanism does not apply to it.
The decision framework for a mild depeg leads to a simple conclusion when applied to this token. There is no issuer. There is no redemption function. The price is not pegged to $1. The only relevant question is whether the token has any utility or demand beyond speculation, and the available facts do not answer that question.
