A monetary liability is an obligation of an issuer that functions as money or as a redeemable monetary claim for its holder.
Modern monetary systems contain liabilities issued by different institutions. Central bank reserves and banknotes are liabilities of the central bank. Commercial bank deposits are liabilities of commercial banks. Issuer-backed stablecoins can create claims on private issuers or arrangements subject to their reserve and redemption terms. Tokenization can change how these liabilities are represented and transferred without changing who ultimately owes the claim.
Identifying the issuer of the liability is separate from identifying the technology that records it. Two tokens on the same ledger can represent claims on different institutions with different risk profiles.
The liability structure determines who owes value to the holder and what credit, redemption, legal, and settlement risks accompany the instrument.
A tokenized commercial bank deposit remains a monetary liability of the bank that issued the deposit even when it is transferred on a distributed ledger.
