Stability depends on conditions
A stablecoin is designed to trade near a currency or another reference asset, but the name does not guarantee the outcome. Stability depends on what supports the value, who promises redemption, and whether market participants trust that promise under stress.
Reserve structure
Cash and short-term government securities, overcollateralized crypto assets, and algorithmic supply mechanisms create very different risks. Read not only the reserve categories but also the custodian, maturity, liquidity, and scope of any audit or attestation. A claim of full backing says little unless the quality and availability of the assets are clear.
Issuance and redemption
Institutions with direct access to issuance and redemption can trade when the market price moves away from the reference value. A retail holder who can only sell on an exchange may face different conditions. Minimum amounts, fees, processing time, and geographic eligibility all affect how redemption works in practice.
Why the market price moves
Heavy selling, limited exchange liquidity, doubts about reserves, or delayed redemptions can break the peg. Prices may also differ across venues or networks. A displayed price near one dollar does not by itself prove that a holder can convert the token into cash at that price and at the required time.
Operational and legal risk
The issuer, bank, custodian, blockchain, and smart contracts each add a separate operational dependency. Freeze powers, sanctions policies, reporting frequency, and the holder’s legal claim differ by token. A decentralized label should be tested against the actual control points in the system.
Documents to review
Review the issuer’s reserve reports, terms, independent assurance scope, and redemption process in the original documents. The key question is not whether the chart has been stable, but who owes what to the holder and which assets would meet that obligation during a stressful period.
