Two of the most consequential financial infrastructure developments of the 2020s are advancing simultaneously: central bank digital currencies and tokenized securities. Understanding how they relate to each other — where they overlap, where they complement, and where they diverge — is essential for institutional participants evaluating their digital finance strategy. The confusion between the two is common but costly: institutions that conflate CBDCs with tokenized securities, or that wait for CBDCs before engaging with tokenized securities, will miss the institutional adoption window.
What CBDCs Are and What They Are Not
The Basic Distinction
A central bank digital currency is digital central bank money — the same type of money that financial institutions hold as reserves at their central bank, but represented in digital token format rather than as an account entry. CBDCs are the liability of the central bank, not of any commercial bank or private issuer. This makes them the safest possible settlement asset: there is no counterparty risk between a CBDC and the central bank that issued it.
CBDCs are not an investment asset, not a yield-bearing instrument, and not a tokenized security. They are a means of payment and settlement — digital money. The closest analogy in current infrastructure is a central bank reserve balance, but in tokenisable format that can be programmed and settled on a blockchain network.
Wholesale vs Retail
The distinction between wholesale and retail CBDC is the most important structural division for institutional finance: wholesale CBDCs are digital central bank money issued exclusively for financial institutions — banks, payment providers, financial market infrastructures — for large-value interbank and securities settlement. Retail CBDCs would be available to the general public as a digital form of cash. Wholesale CBDCs are the relevant category for tokenized securities markets, and all major institutional CBDC initiatives are in the wholesale category.
The Complementary Stack: CBDCs + Tokenized Securities
The reason CBDCs and tokenized securities are complementary rather than competing is structural: every securities transaction has two legs. The securities leg (the transfer of the instrument) is what tokenized securities platforms handle. The cash leg (the payment for the instrument) is what the settlement currency handles. Tokenized securities that settle against a stablecoin settle the cash leg in private money (the stablecoin issuer’s liability). Tokenized securities that settle against a CBDC settle the cash leg in central bank money — the highest-quality settlement asset available.
The ideal institutional capital markets stack is: tokenized securities (institutional asset) + wholesale CBDC (settlement currency) + smart contract (automated delivery versus payment) = T+0 atomic settlement with zero counterparty risk on both legs. This is the model that MAS Singapore’s 2026 pilot is demonstrating: tokenized government bills settled in digital Singapore dollars (wholesale CBDC) via smart contract.
The Global CBDC Landscape
| Project / Initiative | Central Bank(s) | Status | Relevance to Tokenized Securities |
|---|---|---|---|
| BIS Project mBridge | China PBOC, HK HKMA, Thailand, UAE CBUAE | MVP achieved late 2024; live testing | Cross-border wholesale CBDC settlement for trade and securities |
| MAS CBDC Pilot (SGD) | Monetary Authority of Singapore | 2026 pilot for tokenized bills | CBDC-settled tokenized government securities — most advanced stack |
| Banque de France EUR CBDC | Banque de France | Multiple EIB tokenized bond settlements | Digital euro settlement for institutional tokenized bonds |
| BIS Project Agorá | Multiple central banks + commercial banks | 2026 MVP development | Wholesale cross-border payments using tokenized deposits and reserves |
| Bank of England | Bank of England | Wholesale CBDC consultation active | RTGS renewal; digital gilts considerations |
| Digital Dollar (US) | Federal Reserve | Research and analysis phase | No production CBDC; GENIUS Act positions stablecoins as interim solution |
BIS Project mBridge: The Most Advanced Cross-Border Deployment
Project mBridge, led by the Bank for International Settlements Innovation Hub alongside the central banks of China, Hong Kong, Thailand, and UAE, achieved minimum viable product status in late 2024 and has been conducting real-value cross-border wholesale CBDC settlements between participating central banks. For tokenized securities and trade finance with cross-border settlement requirements, mBridge provides the settlement layer that eliminates the correspondent banking friction of traditional cross-border payment — central banks transacting directly with each other in their own digital currencies.
The UAE Central Bank’s participation in mBridge is directly relevant to Blockmaze’s GCC regulatory coverage: as mBridge matures toward fuller production, UAE-regulated tokenized asset transactions could settle in digital dirhams through the mBridge infrastructure rather than through private stablecoin intermediaries — providing central bank settlement quality for GCC-domiciled tokenized securities.
Where CBDCs and Tokenized Securities Diverge
Issuer and Liability
A CBDC is the liability of a central bank; a tokenized security is the liability of the issuer of the underlying security. This difference in counterparty determines the risk profile: holding a CBDC is holding central bank money with no counterparty risk; holding a tokenized security involves the full credit and performance risk of the underlying obligor.
Access and Eligibility
Wholesale CBDCs can only be held by entities with central bank accounts — financial institutions, payment providers, financial market infrastructures. Tokenized securities can be held by any eligible investor who meets the KYB/KYC requirements of the specific instrument and platform. This access asymmetry means that tokenized securities will always require a settlement currency that is accessible to the investor holding them — which is either a stablecoin, a tokenized deposit, or (if they have a central bank account) a wholesale CBDC.
Programmability
Both CBDCs and tokenized securities can carry programmability — CBDC smart contracts can enforce payment conditions; tokenized security smart contracts enforce compliance and lifecycle events. The most powerful institutional use case combines both: a tokenized security smart contract that automatically executes corporate action distributions, while the CBDC smart contract simultaneously delivers the cash payment to eligible recipients in a single atomic transaction.
The US Position: Stablecoins as the Interim Solution
The United States has no production wholesale CBDC and the Federal Reserve has not committed to developing one within a specific timeframe. The GENIUS Act (July 2025), by establishing a federal framework for dollar stablecoins with 1:1 HQLA backing requirements, effectively positions regulated stablecoins as the interim settlement currency for US dollar tokenized securities while the CBDC debate continues. For institutional participants in US dollar-denominated tokenized markets, GENIUS Act-qualified stablecoins (USDC, RLUSD) provide the regulated digital dollar settlement layer that wholesale CBDC would otherwise provide.

Frequently Asked Questions
1. What is the difference between a CBDC and a stablecoin?
A CBDC is the liability of a central bank — digital central bank money with no counterparty risk. A stablecoin is the liability of a private issuer, backed by reserves but carrying the issuer’s counterparty risk. CBDCs represent the highest-quality settlement asset; stablecoins are the practical available alternative in jurisdictions without a production wholesale CBDC.
2. Can tokenized securities settle in CBDCs today?
In limited production contexts, yes: the Banque de France has provided digital euro settlement for EIB tokenized bonds, and MAS Singapore’s 2026 pilot settles tokenized government bills in wholesale SGD CBDC. Universal wholesale CBDC availability for institutional tokenized securities settlement is a 3-5 year horizon in most jurisdictions.
3. Why is wholesale CBDC the ideal settlement currency for institutional tokenized securities?
Because it provides central bank money — the safest settlement asset available, with no counterparty risk — in a blockchain-native format compatible with atomic delivery versus payment in tokenized securities transactions. This eliminates both the credit risk of stablecoin settlement and the timing risk of traditional bank transfer settlement.
4. What is BIS Project mBridge?
A BIS Innovation Hub project involving China (PBOC), Hong Kong (HKMA), Thailand, and the UAE (CBUAE), testing real-value cross-border wholesale CBDC settlements between central banks. It achieved minimum viable product status in late 2024 and is being used for live cross-border wholesale transactions.
5. What is Project Agorá?
A BIS initiative involving multiple central banks and commercial banks exploring wholesale cross-border payments using tokenized deposits and central bank reserves on a shared ledger — specifically the model where tokenized commercial bank liabilities and central bank reserves coexist on the same infrastructure to enable seamless cross-border settlement.
