Unbundling of central-banking functions: the 5 layers

[!info] TL;DR The implicit premise built by the Bretton Woods system (1944) was that the central bank simultaneously bears the 5 functions of the monetary system, and that those functions are sold as a bundle. Since 2022 年, 4 of the 5 functions (#2-#5) have been individually privatized, commoditized, chain-nativized, and made multipolar. The central bank has retained the unit of account (#1); the rest of the unbundling process is the largest financial-infrastructure restructuring of the past 80 years.

Definition of the 5 functions

#	Function	1944-2022 bearer	2022-2030 evolution
1	Unit of Account	monopolized by the central bank	still sovereign (USD/EUR/JPY, etc.)
2	Settlement Medium	central-bank reserves + commercial-bank deposits	privatized → the three layers of SC / TD / MMF intersect in a mesh
3	Payment Rails	SWIFT + central-bank RTGS + commercial-bank clearing	made multipolar → IPS / private DLT / central-bank federations / card networks / the 7-8 segments of new L1 run in parallel
4	Identity / KYC	bank KYC + sovereign ID	commoditized → OCC charter / FIDO / Anchorage / chain-level KYA
5	Enforcement	OFAC + SWIFT sanctions + bank reporting	chain-nativized → §501 Denylist / chain-level freeze / Travel Rule

Triggers of the unbundling

In 2022 年, 3 independent events occurred almost simultaneously and triggered the unbundling:

Event	What it unbundled
Normalization of U.S. Treasury interest rates (4-5%)	Provided the economic model for the privatization of #2 — for the first time, the Treasury interest on stablecoin reserves became viable as a business
The freezing of $300B+ of Russian reserves	Broke the neutrality assumption of #1 → the dollar came to be understood as a political tool → gave political legitimacy to the multipolarization of #3
The public release of ChatGPT	Transformed #4 from “human vs. institution” into the trichotomy of “human vs. institution vs. Agent” → a reconstruction of the protocol layer

Cross-layer network effects

        Customer base (#4)
           ↑↓
   ┌───────┴───────┐
   ↓               ↓
Settlement medium (#2)  Payment rails (#3)
   ↓               ↓
   └───────┬───────┘
           ↓
        Enforcement layer (#5)
        (provided by the regulator)

Strongest path: a player that first holds #4 (customers) + #5 (affinity with the regulatory side) builds #3 and #2 below. Weakest path: starting from the single point of #2 (product) and going upward to look for customers and regulation.

Coverage of major players by layer

Player	#2	#3	#4	#5
Coinbase / Base	USDC-dependent + its own token awaiting issuance	Base L2 + [[fintech/cbbtc-institutional-btc-wrapper	cbBTC]] closed loop	retail KYC + Prime institutional
Stripe / Tempo+Bridge+Privy	USDB	[[fintech/embedded-wallet-fintech-disintermediation-stripe-trojan-horse	Tempo + Connect]]	Bridge OCC + merchant network
Circle / Arc	USDC	[[fintech/issuer-distributor-incentive-realignment-arc-strategy	Arc]]	OCC application pending + USDC brand
JPMorgan / Kinexys	[[fintech/jpmorgan-jpmd-coin	JPMD + MONY/JLTXX]]	Kinexys + [[systems/canton-overview	Canton]]

JPMorgan is the hidden giant: it has closed off sovereignty across all of #2-#5 and does not depend on the crypto ecosystem. Its only weakness is that it is not crypto-native, but the TD path requires no §501 SC qualification.

Applications

It can be used for the following analyses:

Any “financial-infrastructure restructuring” event (a CBDC launch, a SWIFT alternative, a reconstruction of cross-border payments, etc.)
A “layer map” diagnosis of a single player (identifying strengths and weaknesses)
The strategic implications of cross-layer M&A (reinforcing a weak layer vs. further strengthening a strong layer)

A recurring structure:

1944 The establishment of Bretton Woods = the 5 layers were for the first time borne simultaneously by a central-bank coalition
1971 The collapse of Bretton Woods = the de-linking of #1 and #2
2008 Central-bank QE = the central bank intervening in #1 via #2
2022- ongoing = the privatization of the 4 layer
