Five-layer unbundling of central-banking functions

Wiki route

This entry sits under fintech index. Read it against US/EU/Japan stablecoin market-access comparison for peer and contrast context, and Japan’s financial-regulation framework for tokens, cryptoassets, and payments for the broader system and regulatory boundary.

[!info] TL;DR The “five layers” in this entry are an analytical taxonomy that separates a monetary and payment system into (1) the sovereign unit of account and monetary anchor, (2) liabilities and assets used for settlement, (3) messaging, clearing, and settlement infrastructure, (4) identity, access, and compliance operations, and (5) policy, supervision, legal enforcement, and technical controls. It is not a factual claim that central banks historically provided all five layers as one bundle, that four layers have been privatized since 2022, or that they will be replaced by a particular year. In the two-tier monetary system described by the BIS, central bank money, commercial-bank deposits, and private services divide responsibilities; central banks, commercial banks, PSPs, and private networks can overlap within the same function.

Using the five functions as an analytical taxonomy

Sources: BIS Annual Economic Report 2023, Chapter III, BIS central banks and payments report, structure and functions of the Federal Reserve System, IMF fintech topic, and BIS CPMI. These sources describe public- and private-sector roles and the scope of payments, market infrastructures, and fintech; they do not establish a historical five-layer “bundle” or the privatization of four layers.

Evidence checklist for testing a claim

Source note: the table is the analytical procedure used in this entry. Refer to the preceding BIS / Federal Reserve / IMF / CPMI materials for institutional roles and add each operator’s primary materials for a specific product.

The years 1944, 1971, 2008, and 2022 may each provide important historical context, but the sources cited here do not establish a linear causal timeline in which five layers were bundled and then separated. Add primary evidence for each event, institution, and function before making a historical claim.

Overlapping roles by type of actor

This table does not rank actors by strength or prescribe an integration sequence. In practice, one actor may perform several functions, while several actors may jointly provide a single function.

Verification examples using public products

Sources: Coinbase’s description of Base, Stripe’s announcement that it completed the Bridge acquisition, Circle’s Arc announcement, and J.P. Morgan’s description of JPM Coin. This table is a verification map of public product surfaces, not a ranking or list of regulatory approvals.

“Layer coverage” in this framework is not a score of market control, sovereignty, authorization, legal advantage, or investment attractiveness. For a commercial-bank deposit arrangement such as JPM Coin, identify the issuer liability and access conditions rather than automatically placing it in the same regulatory category as a stablecoin.

Application procedure

• Record the product’s unit of account, issuer liability, and redemption right first
• Do not combine messaging, clearing, settlement, and finality into one “rail”; identify each operator and rulebook
• Track onboarding, KYC / AML, sanctions handling, wallet / key controls, and legal-enforcement authority in separate fields
• Do not treat a PoC, testnet, completed acquisition, commercial launch, and regulatory approval as the same maturity state
• Compare the same reference date, jurisdiction, and user scope; require party materials and additional evidence for causation or forecasts
