Stablecoins, Tokenized Deposits and DvP

AI-assisted manuscript. Payment assets and amounts are hypothetical, with no assertion of insurance or guaranteed redemption.

Learning objectives

• Distinguish a stablecoin arrangement from a tokenized bank-deposit claim.
• Separate atomic exchange from the quality of settlement money.
• Map delivery-versus-payment failure cases across system boundaries.

The payment token has its own structure

Calling an asset “digital money” does not identify its issuer, claim, redemption conditions or settlement mechanism. A tokenized deposit and a stablecoin can have different liability structures and transfer arrangements. Read the actual documents rather than treating a common denomination as identical credit quality.

BIS Bulletin 73 compares stablecoins and tokenized deposits in relation to the singleness of money. It examines how bearer-like stablecoins can deviate from par, and how non-bearer deposit arrangements settled in central-bank money may support a different outcome. These are analytical models, not guarantees that every deposit token has insurance or that every stablecoin behaves identically. BIS: Stablecoins versus tokenised deposits

The payment asset therefore needs its own rights, liquidity, operational and failure analysis, even when the asset exchange is technically well coordinated.

Worked example: atomic tokens, uncertain cash

Imagine a buyer purchases 50 fictional bond units at 20 currency units each. The teaching transaction exchanges them atomically for 1,000 settlement tokens. Both token legs complete together, and the seller now holds 1,000 payment tokens.

Suppose the payment token's assumed redemption process subsequently becomes unavailable. The atomic exchange did not fail at its code boundary, yet the seller cannot currently obtain the expected bank currency. Principal-risk reduction in the exchange is not the same as elimination of payment-issuer or redemption risk.

Now imagine a second design uses an external bank payment. The bond token is transferred first, with a bank confirmation promised later. Without a mechanism linking recognized final settlement of both obligations, describing this as atomic DvP would overstate the boundary. A notification that payment was instructed is not final payment evidence.

Token DvP boundary: bond token ↔ payment token
Outside that boundary: payment issuer → redemption → bank currency

Cross-system proposal: bond record ↔ external payment
Required questions: finality, linkage, outage, cancellation, reconciliation

The CPMI-IOSCO PFMI treats settlement money and linked obligations as distinct principles. Principle 12 links final settlement of obligations to address principal risk, while other principles address the broader legal and operational arrangement. BIS: PFMI

Ask what settles, where and for whom

Identify the payment issuer, the holder's claim, permitted holders, conversion path, fees and operating hours. Check whether settlement discharges the buyer's obligation under the actual trade terms or merely creates a further claim. A shared currency label such as USD is not proof of identical legal or economic properties.

For a cross-system design, map reservation, confirmation, finality and recovery on both sides. A time-limited reservation can expire while a delayed external payment later arrives. The workflow needs an unresolved or exception state and an authorized return or completion process rather than assuming all delays are failures.

Test insufficient funds, paused payment issuer, stale eligibility, delayed bank evidence, one system unavailable and duplicate messages. Preserve both position and payment evidence. A simulator can demonstrate the intended invariant without proving live legal settlement or a commercial redemption route.

Common misconceptions

“Stable price means guaranteed value.” A reference price and a legally enforceable, available redemption route are different facts.

“All deposit tokens have the same protection.” Institution, jurisdiction, account structure and holder eligibility require verification.

“Atomic exchange proves final bank cash.” The atomic operation may cover tokens only.

Risks and limits

This is education based on international research and infrastructure principles, not a current legal opinion on any currency issuer. No deposit insurance, custody protection, eligibility or redemption is inferred. All numerical amounts and suspension scenarios are invented. No stablecoin, bank account or DvP infrastructure was tested.

Exercise and answer

Exercise: A seller receives 1,000 payment tokens atomically, but cannot redeem them for bank currency. Can both statements be true?

Answer: Yes. The token exchange can complete while a separate redemption claim fails or is delayed. Report the technical exchange and the external payment outcome separately.
