Lesson Objective
What is a stablecoin?
A stablecoin is a blockchain-based token designed to maintain a value relative to a reference asset — most commonly one unit of a national currency such as the US dollar. The reference is often called a peg. The token can move across a blockchain, but its stability depends on an arrangement surrounding issuance, reserves, redemption, governance and market liquidity.
A target value is not a guarantee. A stablecoin can trade above or below its reference price, and the ability of a particular holder to redeem at par may be limited by eligibility rules, minimum amounts, fees, geography or an intermediary.
The Central Question
Why stablecoins exist
Trading and settlement: They provide a relatively stable unit for buying, selling and settling other digital assets.
Payments: They can transfer value around the clock across supported blockchain networks.
Cross-border activity: They may reduce some time and coordination frictions, although fees, regulation and conversion remain important.
DeFi: They are commonly used as collateral, trading pairs and settlement assets in decentralized applications.
Treasury operations: Some businesses use them for digital-asset liquidity or programmable payment experiments.
The main stabilization models
| Model | How stability is pursued | Important exposure |
|---|---|---|
| Fiat-reserve backed | An issuer creates tokens and holds reserve assets intended to support redemption at the reference value. | Issuer, custodian, reserve quality, liquidity, legal claim and redemption access. |
| Crypto-collateralized | Digital assets are locked in smart contracts, often at a value greater than the stablecoins issued. | Collateral volatility, liquidation, oracle, smart-contract and governance risk. |
| Algorithmic or endogenous | Rules change supply, incentives or related-token economics to encourage the target price. | Confidence spirals, weak redemption value, liquidity loss and failure of incentives. |
| Commodity referenced | Tokens reference an asset such as gold and may claim backing through stored inventory or contractual rights. | Custody, verification, legal title, redemption conditions and commodity price exposure. |
Not All Backing Is Equal
How fiat-reserve stablecoins are issued
Customer funds the issuer.
An eligible customer transfers conventional currency through approved banking channels.
Tokens are minted.
The issuer creates an equivalent quantity of tokens, subject to its terms, and delivers them to a blockchain address.
Tokens circulate.
Users transfer the tokens through wallets, exchanges, payment providers or decentralized applications.
Tokens return for redemption.
An eligible holder submits tokens to the issuer or an intermediary and requests the reference currency.
Tokens are burned.
The redeemed tokens are removed from circulation and reserve assets fund the payout.
How the peg is maintained
When reliable minting and redemption are available near the reference value, market participants may buy discounted tokens and redeem them, or create tokens and sell them when the market price is higher. This arbitrage can pull the market price toward the peg.
That mechanism weakens when redemption is slow or restricted, reserve assets cannot be sold quickly, banking access is disrupted, transaction costs are high, or confidence falls. Secondary-market liquidity is helpful, but it is not the same as a direct legal right to redeem with the issuer.
The anatomy of a reserve
| Reserve feature | Questions to ask |
|---|---|
| Composition | What proportion is cash, bank deposits, short-term government securities or other assets? |
| Liquidity | Can assets be converted into cash quickly without a material loss during heavy redemptions? |
| Custody | Who holds the assets, in whose name, and are they segregated from the issuer's own property? |
| Matching | Do the quantity and currency of reserves align with tokens in circulation and redemption obligations? |
| Verification | Are disclosures management assertions, attestations or full financial-statement audits — and how current are they? |
| Legal protection | What claim does a token holder have if the issuer, bank, custodian or service provider fails? |
Attestation is not the same as an audit. A reserve attestation generally reports on specified information at a point in time under an agreed scope. A financial-statement audit addresses financial statements and controls within a broader reporting framework. Neither label should be interpreted without reading the period, criteria, exclusions, assurance standard and responsible accounting firm.
Timing Matters
Why a stablecoin may depeg
Questions about whether reserves are sufficient, liquid or legally available.
Failure or disruption at a bank, custodian, blockchain, bridge, exchange or redemption provider.
Heavy selling combined with limited market liquidity or restricted direct redemption.
Smart-contract defects, compromised administrative keys or inaccurate price oracles.
Regulatory action, sanctions, freezing powers or a change in issuer terms.
For crypto-collateralized models, a rapid fall in collateral value and forced liquidations.
For algorithmic models, a loss of confidence that overwhelms supply-adjustment incentives.
Stablecoin risk map
| Risk | What it means in practice |
|---|---|
| Redemption risk | The holder may not be able to exchange the token for the reference asset promptly or at par. |
| Reserve risk | Assets may lose value, become illiquid, be concentrated or be unavailable in insolvency. |
| Counterparty risk | The issuer, bank, custodian, exchange or payment provider may fail or suspend service. |
| Technology risk | Blockchains, smart contracts, bridges, wallets and administrative systems can fail or be attacked. |
| Market risk | The token can trade away from its target and liquidity can disappear during stress. |
| Legal and regulatory risk | Rights, classifications, permitted uses and compliance obligations vary by jurisdiction and may change. |
| Operational risk | Errors in addresses, networks, approvals, reconciliation or key control can cause loss. |
A stablecoin is not automatically a bank deposit
| Instrument | Issuer / liability | Key distinction |
|---|---|---|
| Cash | Central bank | A direct form of central bank money; physical cash does not require an issuer redemption process. |
| Commercial-bank deposit | Regulated bank | A claim on the bank, generally within banking, deposit-insurance and payment-system rules. |
| Fiat-backed stablecoin | Private stablecoin arrangement | A blockchain token whose rights, backing and redemption depend on its structure and terms. |
| Tokenized deposit | Bank | A digital representation of a bank-deposit liability, potentially recorded or transferred on distributed infrastructure. |
| CBDC | Central bank | A digital central-bank liability; conceptually distinct from privately issued stablecoins. |
Networks, bridges and wrapped versions
The same brand may appear natively on several blockchains. It may also appear as a bridged or wrapped representation issued by another system. These versions can have different contract addresses, redemption paths and risks.
Confirm the exact blockchain network supported by the sender and recipient.
Verify the token contract through the issuer or another authoritative source.
Determine whether the token is native, bridged or wrapped and who controls the bridge or backing asset.
Keep enough of the network's required fee asset to move the stablecoin later.
Use a small test transaction when working with a new address, network or service.
Evaluating a stablecoin
Reference: What value is the token intended to track, and in which currency is redemption made?
Issuer and jurisdiction: Who operates the arrangement, and what laws and regulators apply?
Holder's claim: Is there a contractual redemption right, and who is eligible to use it?
Reserve: What assets support the token, where are they held and how frequently are they reported?
Assurance: Who verifies the disclosures, using what standard and scope?
Redemption mechanics: Consider minimums, fees, timing, identity checks and geographic restrictions.
Technology: Identify supported networks, contract controls, upgrade powers, freeze functions and bridge exposure.
Market access: Where can the token be converted, and how deep is liquidity during stress?
Use case: Does the benefit justify the combined issuer, technology, operational and regulatory risks?
Stablecoins in business and accounting
A stable market price does not automatically determine accounting classification. The analysis depends on the holder's rights, the instrument's terms, applicable accounting standards, business purpose and facts at the reporting date.
Record the legal owner, wallet or custodian, token contract, network and quantity.
Separate stablecoin holdings from conventional cash and bank deposits in internal records.
Reconcile blockchain activity, custodian records, fees and general-ledger entries.
Document valuation sources, depegging events, restrictions and subsequent events.
Establish authorization, custody, counterparty and concentration limits.
Consider tax, sanctions, anti-money-laundering and cross-border payment requirements.
Accounting Perspective
Key takeaways
A stablecoin targets a reference value; it does not guarantee that value.
Reserve-backed, crypto-collateralized and algorithmic models rely on different stabilization mechanisms and create different risks.
Direct redemption rights and secondary-market liquidity are not the same thing.
Reserve composition, liquidity, custody, legal protection and verification all matter.
Stablecoins are not automatically equivalent to cash, bank deposits, tokenized deposits or CBDCs.
The exact token contract and network must be verified before a transfer.
