A Stablecoin's Peg Depends on Its Backing and Redemption

A stablecoin aims to maintain a reference value, often one US dollar. The target does not make the token equivalent to a dollar in a bank account. Its ability to trade near that value depends on its backing, redemption arrangements, market liquidity and the systems through which holders can move between tokens and money.

The distinction becomes visible during a depeg, when the market price moves away from the target. A small deviation can reflect transaction costs or temporary trading conditions. A persistent discount can indicate deeper doubts about reserves or access to redemption. Price alone does not identify the cause. SBI and Shinhan Card’s yen-payment tests put these redemption and settlement questions into a proposed retail-payment setting.

Different backing models create different exposures

A reserve-backed token may rely on cash and financial assets held by an issuer. Other designs use crypto collateral, often with additional collateral above the amount issued. Algorithmic arrangements may depend heavily on incentives involving another token. These mechanisms should not be grouped together as though the word stablecoin described one balance sheet.

Circle's disclosures provide an issuer-specific example of reserve reporting for USDC. They do not establish the backing of unrelated tokens. The Federal Reserve's analysis of stablecoin fragility emphasizes that demand for prompt redemption can create stress even when an instrument is designed to maintain a fixed value.

For a hypothetical issuer with 1 billion tokens and $1 billion of reserves at stated value, the initial backing ratio is 100%. If reserve assets lose 2% and no capital absorbs the loss, assets become $980 million. That is $0.98 per token before liquidation expenses or other claims. Equal nominal starting values do not eliminate asset-price risk.

Liquidity differs from solvency

An issuer can hold assets whose ultimate proceeds cover the tokens yet lack cash immediately available to meet withdrawals. Banking hours, settlement cycles, operational outages or the need to sell securities can affect access. A reserve's quality and its availability are related but separate questions.

Suppose the hypothetical issuer has $100 million of immediately accessible cash and $900 million of securities. Holders request $250 million of redemptions. Meeting the requests requires another $150 million from sales, maturities or financing. This is a liquidity problem even before considering whether the securities have lost value.

If selling the required assets incurs a discount, a liquidity problem can turn into an economic loss. It is therefore useful to distinguish a statement about reserves at a reporting date from evidence about how quickly those reserves can be converted under stress. An attestation also has a defined scope and should not automatically be called a full financial-statement audit.

Redemption supports arbitrage only when accessible

If a token trades at $0.97 and an eligible participant can reliably redeem at $1, buying and redeeming may offer a gross spread. For a hypothetical purchase of 100,000 tokens, the $97,000 purchase cost compares with $100,000 of redemption proceeds. The $3,000 difference precedes every fee, delay and risk.

If total costs are $500, the apparent net spread becomes $2,500. But if redemption is suspended or eligibility is absent, the calculation cannot be executed as assumed. The discount can then persist. Retail holders may depend on an exchange market rather than having the same direct redemption access as an approved institutional customer.

A token can also trade above target when demand exceeds immediately available supply or conversion is constrained. A premium is not a new guaranteed reference price. The route back to parity depends on issuance and arbitrage functioning in both directions.

Extra layers add extra claims

A stablecoin held through a trading platform adds the platform's custody and withdrawal arrangements. A wrapped token or cross-chain representation can add bridge and contract dependencies. Placing a token in a DeFi lending arrangement adds another exposure beyond the underlying peg.

For a hypothetical 10,000-token holding marked at $1, a market discount to $0.90 reduces quoted value to $9,000. A separate lending loss could reduce it further. An advertised yield of 5% does not compensate automatically for either event, and the existence of reserves does not guarantee a particular intermediary's promise.

Evaluate the actual claim

Check the issuer, asset composition, reserve-report date, redemption eligibility, costs and relevant legal terms. Token ownership should not be assumed to carry bank-deposit insurance. Protections depend on the actual structure and applicable rules, rather than a logo or a stable market price yesterday.

Compare the product with bank deposits and money market funds only after identifying those differences. A peg is an intended price relationship. The institutions, assets and contractual access supporting it determine how resilient that relationship may be when holders seek cash at the same time.
