Follow 1,000 hypothetical dollar tokens from a wallet to a bank account. The number of units is only the starting point: the final dollars depend on an available price, an eligible sale or redemption route and the costs along it. A ledger balance and spendable bank money describe different stages of that journey.
A peg is the value a token aims to track. For a dollar stablecoin, that usually means a market price near $1. The target is useful because it supplies a reference point. It does not tell you what keeps the token close to that point or what happens when holders want to leave.
Separate the three questions
Begin with price: what would a buyer actually pay for the token on the venue available to you? Then ask about backing: what assets or collateral support the system? Finally, ask about redemption: who can exchange the token for ordinary money, under what conditions?
Circle’s USDC page illustrates the distinction. It describes USDC as reserve-backed and redeemable one for one, while its FAQ says Circle Mint serves eligible institutions rather than individuals or small businesses. Everyday users are directed to exchanges and other intermediaries. The issuer’s description of a redemption mechanism does not mean every holder has the same direct access.
An exchange sale is also a different transaction from issuer redemption. You may receive a price offered by another market participant, then rely on the exchange to withdraw the proceeds. Ask which step a service means when it advertises “cash out.”
Why a discount can attract buyers
Imagine a fictional token trading at $0.99. An eligible participant that can buy 1,000 units for $990 and redeem them for $1,000 has a $10 gross difference. Buying tokens below the target can create demand, while redemption removes those units from circulation. This illustrates an incentive that can help pull a price toward the peg; it is not a trade recommendation.
Now add hypothetical costs. A $6 trading charge, $3 transfer charge and $4 redemption charge total $13. The $10 difference becomes a $3 loss before any other cost. If the market moves before the purchase completes, or redemption is delayed, the calculation changes again.
The same reasoning explains why seeing a discount is not enough. You need an executable purchase, an eligible exit and a reasonable expectation that both steps can complete. A screenshot of yesterday’s price provides none of those on its own.
Above the target, access to minting and selling can create a different incentive. Circle describes minting when a business deposits dollars and receives newly issued USDC; redemption takes tokens out of circulation. That is a specific issuer model, not a description of every stablecoin.
Read backing evidence with its scope
A reserve statement should identify assets, the date examined and what the examiner actually concluded. A headline saying “fully backed” leaves those details unanswered. Backing also has to be considered alongside the ability to meet withdrawals.
New York DFS’s June 2022 guidance is a concrete historical example. For issuers within its scope, it addresses segregated reserves, acceptable reserve assets, redemption conditions and independent attestations. Its redemption framework includes compliant orders and successful onboarding; it does not treat every token transfer as an immediate cash payment.
The useful lesson is the structure of the questions. What is held, for whose benefit, and how does a holder reach it? This 2022 document is not a complete statement of current law everywhere or proof that a particular token meets those requirements. Likewise, assets held at an insured bank do not by themselves establish insurance for your token balance.
Collateral and swaps add different dependencies
Some systems use collateral and smart contracts rather than a simple dollar-in, token-out issuer process. For example, Sky’s LitePSM documentation describes swaps involving DAI, USDS and external stablecoins such as USDC, using pools of pre-minted tokens.
A token-to-token swap can help connect markets, but it is not necessarily an exchange for dollars in a bank. After the swap, you still need to examine the asset you received and its exit route. Replacing token A with token B can replace one set of dependencies with another.
Keep the distinction explicit when evaluating a claim that a token is “decentralized.” Which part operates through contracts? Which assets, service providers or governance decisions remain important? A single label cannot answer those questions.
A peg can be close without being constant
A 2023 BIS paper examined 68 stablecoins and reported that none in its sample maintained parity at every moment. The authors also identified gaps in available data. This is historical evidence about the sample studied, not a prediction of today’s prices or a ranking of current issuers.
It supports a narrower point: the name “stablecoin” does not establish uninterrupted stability. A brief deviation and an unusable redemption route are also different problems. Price observations alone cannot show which one a holder faces.
Draw your own exit map
For a specific token, write a short route: wallet, receiving service, sale or redemption, withdrawal, bank account. Beside each step, note the exact network and token, who operates the service, who is eligible and which costs or conditions apply. Leave unknown details visible.
Then ask what evidence would show the route works for you. A supported network is not enough if withdrawals are unavailable. An attractive quote is not enough if the trade is too small to meet a minimum. A current reserve report is useful, but it does not replace the account terms.
The goal is to understand what your balance represents before relying on it. A dollar price, adequate backing and a usable redemption route are related achievements. Each needs its own evidence.
For a comparison of reserve-backed and incentive-based designs, continue with different ways to lose a dollar peg.
