Money, Deposits and Payments

A displayed balance does not by itself identify the liability behind it. A customer can have a claim against a bank, while the bank uses another asset to settle with a different institution. A payment interface, the customer claim and the interbank step should therefore be mapped separately.

What you will learn

  • Distinguish a customer's deposit claim from interbank settlement assets.
  • Trace the customer and bank sides of a payment.
  • Compare a payment instruction with completed recipient credit.

Money needs an issuer and a settlement arrangement

A displayed balance does not by itself identify the liability behind it. A customer can have a claim against a bank, while the bank uses another asset to settle with a different institution. A payment interface, the customer claim and the interbank step should therefore be mapped separately.

BIS Bulletin 73 examines stablecoins, tokenized deposits and the singleness of money. It distinguishes monetary arrangements rather than assuming every token bearing a currency label is the same claim. Its models do not establish deposit insurance or redemption protection for a named product. BIS Bulletin 73

PFMI also treats settlement money as a separate design question alongside finality and linked obligations. BIS: PFMI

Worked example: two layers move by 40

Imagine customer Ana has a 100-unit deposit at fictional Bank A. She instructs a 40 payment to Bo at Bank B. Assume the teaching process settles through bank reserves with no fees, credit extensions or other flows.

Ana's deposit becomes 60 and Bo receives a 40 deposit credit. In the partial bank-asset view, A's reserves start at 80 and B's at 20. Settlement moves 40, leaving A at 40 and B at 60. The total reserve amount in this isolated example remains 100, and the two displayed customer deposits still total 100.

This is not a complete bank balance sheet: loans, capital, other customers and liabilities are deliberately omitted. It isolates why the customer's deposit record and the banks' settlement asset are different layers. A payment app showing “instruction accepted” does not prove that both recorded changes have completed.

Customer claims: Ana at A 100 → 60; Bo at B 0 → 40
Bank reserves: A 80 → 40; B 20 → 60
Instruction → clearing/settlement process → recipient credit evidence

Apply the same questions to digital forms

If a token represents a deposit, identify which bank liability it records and how a transfer affects the recipient's claim. If it is a stablecoin, identify the token issuer, holder entitlement, reserve and redemption arrangement. Technical portability does not erase those distinctions.

A merchant may accept a token itself or require bank currency after conversion. The agreed completion condition decides what evidence is needed. Fees, exchange rates, operating hours, eligibility and suspension terms also need current documents. Do not infer instant settlement merely from a fast customer notification.

A system can improve instructions while leaving the same external settlement process. That can still be useful, but the benefit should be described within its actual boundary. Likewise, linking asset and payment tokens does not automatically establish final redemption into another form of money.

Common misconceptions

“The app balance is central-bank money.” It can represent another institution's liability.

“A payment creates new money equal to every gross transfer.” In the stated model it moves existing claims and settlement assets.

“All currency-denominated tokens have identical protection.” Issuer, legal claim, holder scope and settlement differ.

Risks and limits

No actual banking license, reserve process, money-supply measure or insurance is determined. Real banking includes additional balance-sheet and settlement mechanisms omitted here. The model is not a macroeconomic forecast or operational specification. No account, bank transfer or token redemption was tested.

Exercise and answer

Exercise: Under the fictional reserve transfer, A starts with 80 and B with 20, then 40 moves A to B. What are the final reserve amounts, and is the customer notification alone sufficient evidence?

Answer: A has 40 and B 60. A notification proves only its defined stage; recognized settlement and recipient credit require their own evidence.
