Stablecoins are designed to keep their value close to a reference asset, but “stable” describes an objective, not a guarantee.
A token targeting one U.S. dollar still needs a mechanism connecting its market price to that target. Depending on the structure, that mechanism may rely on reserves and redemption, crypto collateral, smart contracts, market incentives, or a combination of these elements.
To understand a stablecoin, ask what it references, what supports that value, who can redeem it, and what could cause the mechanism to fail.
What Is a Stablecoin?
Stablecoins are cryptoassets designed to maintain a relatively stable value against a specified reference asset, currency, or basket. The U.S. dollar is the dominant reference today, but stable-value arrangements can reference other official currencies or other values. For the broader taxonomy, see Kenson Investments’ Digital Assets Primer.
A reference price is only one part of the structure. A dollar-linked token does not remain near $1 simply because it is described as dollar-pegged. The more important question is how the system responds when market demand moves the token above or below its target.
Three Main Stablecoin Structures
Stablecoins are commonly grouped into fiat or reserve-backed, crypto-backed, and algorithmic models. These are useful educational categories, but real systems can combine features from more than one.
Fiat or Reserve-Backed Stablecoins
Reserve-backed stablecoins are issued against assets intended to support their value and redemption. Those reserves do not necessarily consist only of cash sitting in one bank account. BIS research notes that major fiat-backed issuers commonly hold combinations of short-dated public debt and claims on banks, while the exact composition varies by issuer and legal structure.
The relevant questions include reserve sufficiency, liquidity and duration, custody, segregation, disclosure, independent assurance, and direct redemption. A token can appear fully backed on paper while still face problems if reserve assets cannot be accessed or converted quickly during heavy redemptions.
Issuer-specific reserve analysis belongs on specialist pages such as Kenson’s stablecoin reserve research, rather than in this fundamentals overview.
Crypto-Backed Stablecoins
Crypto-backed stablecoins use other cryptoassets as collateral. Because that collateral can be volatile, these systems commonly require collateral with a market value greater than the value of stablecoins issued against it. This overcollateralization creates a buffer against falling collateral prices. It does not guarantee stability.
These designs can depend on collateral ratios, liquidations, market liquidity, price oracles, smart contracts, blockchain availability, and governance. Sharp collateral declines or failed liquidations can quickly erode the buffer. Detailed lending mechanics belong in DeFi Fundamentals.
Algorithmic Stablecoins
Algorithmic stablecoins rely substantially on protocol rules and market incentives rather than conventional reserve assets alone. Mechanisms may involve changes in token supply, mint-and-burn relationships, arbitrage incentives, linked tokens, governance rules, or partial collateral.
These systems can become reflexive: falling confidence can weaken the mechanism intended to restore the peg while increasing selling pressure.
TerraUSD, or UST, provides a historical example. UST was the stablecoin; LUNA was the linked asset used within its stabilization mechanism. Algorithmic designs are not all identical or completely uncollateralized, and some hybrid models combine collateral with automated mechanisms.
How Issuance and Redemption Support the Peg
For many stablecoins, issuance and redemption connect the token’s market price to its target value. When new tokens are issued, an eligible user or participant provides the required assets or collateral. When tokens are redeemed, they leave circulation in exchange for the reference value or defined collateral according to the system’s rules.
This can create an arbitrage mechanism. If a redeemable dollar stablecoin trades materially below $1, qualified participants may be able to buy it in the market and redeem near the reference value. Their buying can help move the secondary price back toward the target. The reverse can occur when the token trades above its target.
Direct redemption is not necessarily available to every holder. Eligibility may depend on minimums, compliance checks, jurisdiction, fees, banking hours, or processing times. Exchange users may depend on other participants to connect secondary markets with issuer redemption.
Primary and Secondary Liquidity Are Different
Primary liquidity concerns the ability of an eligible participant to issue or redeem directly through the issuer or protocol. Secondary liquidity concerns the ability to buy or sell the stablecoin efficiently in exchanges, decentralized markets, or other venues.
A stablecoin can have functional redemption while its secondary-market price moves away from par during heavy selling. Conversely, deep exchange liquidity can exist even when most holders lack direct issuer redemption. Liquidity can also differ by venue or blockchain.
This distinction matters for digital asset liquidity risk. A $1 target does not guarantee execution at $1, and deep secondary liquidity does not prove reserve quality. Detailed execution mechanics belong in Kenson’s slippage execution guide.
Why Stablecoins Depeg
A depeg occurs when the market price moves meaningfully away from its reference value. Triggers include reserve concerns, redemption delays or restrictions, one-sided liquidity shocks, issuer or banking disruption, falling crypto collateral, failed liquidations, oracle or smart-contract failures, reflexive algorithmic failure, and network, bridge, or regulatory disruption.
Not every depeg means insolvency. A temporary market imbalance can push a token away from its target even if redemption ultimately continues. A deeper problem exists when backing, redemption, or the stabilization mechanism itself is impaired.
Reserves Matter, but Redemption Matters Too
A reserve-backed stablecoin cannot be evaluated only by asking whether reported assets equal tokens outstanding. Reserve quality matters.
Short-duration, highly liquid assets may be easier to convert during heavy redemption demand than longer-duration or less liquid instruments. Banking concentration and legal segregation also matter.
A reserve disclosure, an attestation or examination, and a financial-statement audit are not automatically the same thing. They can cover different information and provide different levels of assurance. Independent assurance does not guarantee future solvency or liquidity.
The practical question is broader: can the backing remain accessible and liquid when many holders want to redeem at the same time?
Issuer and Counterparty Risk
Reserve-backed stablecoins can depend on several organizations simultaneously, including the issuer, banks holding reserves, custodians, asset managers, brokers, redemption partners, exchanges, and infrastructure providers. Onchain transferability does not remove those dependencies.
A useful evaluation asks who owes the holder value, what rights exist, where reserves are held, and what happens if the issuer or a reserve institution fails. These dependencies can create digital asset operational risk even when the blockchain continues functioning.
Technology and Operational Risk
Technology risk varies considerably among stablecoins. A crypto-backed stablecoin may depend heavily on smart contracts, collateral-management code, oracles, automated liquidations, and governance.
A centrally issued reserve-backed stablecoin may depend more heavily on issuer systems, reserve banking, redemption infrastructure, administrative keys, and service providers. Multi-chain stablecoins can also introduce bridge or chain-specific dependencies.
What Are Stablecoins Used For?
One major use remains crypto trading. Stablecoins can function as quote assets, settlement instruments, and relatively stable units for moving between crypto positions without immediately returning to conventional banking rails.
They are also used in DeFi for lending, borrowing, collateral, automated market makers, and programmable financial applications. Stablecoins can support onchain settlement and are increasingly explored for payments, remittances, commercial transfers, and treasury operations.
Those use cases should not be overstated. BIS research in 2026 found that headline transaction volumes were much larger than estimated real-economy payment flows, with crypto-market activity still dominating use. Exchange fees, spreads, currency conversion, and on-ramp or off-ramp costs also mean transfers are not universally cheaper.
Kenson’s specialist research on payments and treasury operations, institutional digital cash, and stablecoin liquidity infrastructure addresses those workflows in greater depth.
Stablecoins Are Not Bank Deposits
A stablecoin and a commercial bank deposit can both appear as dollar-denominated digital balances while representing different legal claims.
A commercial bank deposit is a liability of the bank to the depositor. A stablecoin is governed by its issuer or protocol, reserve and redemption arrangements, and applicable legal framework. A tokenized deposit remains a bank deposit even though blockchain or distributed-ledger technology may be used to record or transfer it.
In the United States, the FDIC’s April 2026 proposed GENIUS Act rule states that deposits held as reserves for payment stablecoins would not provide pass-through deposit insurance to stablecoin holders. It also states that a tokenized deposit meeting the legal definition of a deposit would not be treated differently merely because tokenized technology records it.
Stablecoins also differ from CBDCs or tokenized central-bank money, which are central-bank liabilities rather than private stablecoin liabilities.
Stablecoin Yield Is a Separate Risk Layer
A stablecoin does not inherently generate yield simply because it maintains a relatively stable reference value. Rewards can instead come from an exchange program, lending arrangement, DeFi protocol, liquidity pool, or other financial product. Those arrangements introduce additional counterparty, credit, liquidity, smart-contract, regulatory, or platform risk.
The U.S. GENIUS Act prohibits permitted payment stablecoin issuers and qualifying foreign payment stablecoin issuers from paying holders interest or yield solely for holding, using, or retaining the payment stablecoin once the relevant framework applies. That does not make every independent third-party reward or lending arrangement the same legal product.
How to Evaluate a Stablecoin
Rather than asking whether a stablecoin is a good investment, evaluate the structure underneath it:
- What asset or value does it reference?
- What mechanism attempts to maintain that value?
- What reserves or collateral support it?
- Who issues or governs it?
- Who holds the reserve assets?
- Who can redeem directly?
- What fees, minimums, compliance checks, and processing times apply?
- What reserve disclosures are available?
- What type of independent assurance is provided?
- Where does secondary-market liquidity exist?
- Which blockchains or bridges does it depend on?
- What smart-contract or oracle dependencies exist?
- What legal rights does the holder have?
- Which regulatory regime applies?
- How has the mechanism behaved during previous periods of stress?
This turns stablecoin evaluation into a review of backing, liquidity, rights, dependencies, and failure modes rather than a judgment based only on whether the market price currently reads $1.
Regulatory Treatment Depends on Jurisdiction
Stablecoin regulation is not globally uniform. In the United States, the GENIUS Act became law on July 18, 2025. Its general effective date is the earlier of January 18, 2027 or 120 days after the primary federal payment stablecoin regulators issue final implementing regulations.
As of October 5, 2026, the OCC’s principal prudential implementation rule, the FDIC’s prudential rule, a joint AML/CFT and customer-identification proposal, and September Federal Reserve implementation rules remain proposals rather than final rules.
Treasury also issued an interim final procedural rule effective September 30, 2026 for state-regulator certifications, but that does not by itself make the broader regime generally effective.
Current SEC guidance treats stablecoins as a distinct cryptoasset category and recognizes the statutory treatment that qualifying payment stablecoins will receive under the GENIUS Act framework. Other stablecoin structures can require separate analysis.
In the European Union, MiCA distinguishes an e-money token, which references one official currency, from an asset-referenced token, which can reference another value, right, asset, or combination.
Globally, the Financial Stability Board has found implementation of stablecoin regulation incomplete and uneven across jurisdictions. Regulatory treatment therefore cannot be inferred simply from the word stablecoin. For deeper institutional analysis, see Kenson’s stablecoin regulatory due-diligence research.
Stablecoin Structure Comparison
| Stablecoin Structure | Backing / Stability Mechanism | How the Peg Is Supported | Key Dependencies | Typical Risks |
|---|---|---|---|---|
| Fiat/reserve-backed | Cash and/or liquid reserve assets | Issuance, redemption and arbitrage | Issuer, banks, custodians, reserve assets, redemption | Issuer, reserve, bank, liquidity and legal risk |
| Crypto-backed | Onchain crypto collateral, often overcollateralized | Collateral buffers, liquidations and arbitrage | Collateral, oracles, smart contracts, liquidators | Collateral decline, liquidation, oracle and technology risk |
| Algorithmic | Protocol incentives, supply changes or linked-token economics | Market incentives and automated stabilization | Liquidity, confidence, governance, protocol design | Reflexive depeg, liquidity and mechanism failure |
| Hybrid | Combination of collateral and algorithmic or issuer mechanisms | Multiple stabilization mechanisms | Depends on design | Combined collateral, governance, issuer and technology risks |
Understand the Stability Mechanism Before the Label
Stablecoins can reduce exposure to the price swings associated with many other cryptoassets while they maintain their reference value, but that does not make them risk-free.
Their stability depends on mechanisms that can include reserves, collateral, redemption, market liquidity, counterparties, software, governance, and regulation. A stablecoin should therefore be evaluated by asking not only whether it currently trades near its target, but what keeps it there and what happens when the system comes under stress.
