CBDCs vs Tokenized Deposits: How Digital Money Works

Understand CBDCs vs tokenized deposits — how each instrument works, who issues them, and why the difference shapes the future of payments.

Introduction

Two distinct forms of programmable digital money are advancing through the global financial system simultaneously. A central bank digital currency (CBDC) — a direct liability of a central bank, denominated in the national unit of account — offers sovereign-backed digital cash without any commercial bank intermediary. A tokenized deposit is a blockchain token issued by a commercial bank that represents a 1:1 claim on an existing fiat deposit, keeping the underlying obligation on the bank's own balance sheet.

The distinction matters because the two instruments occupy different positions in the monetary hierarchy. CBDCs, whether designed for the general public (retail CBDC) or for financial institutions settling large transactions (wholesale CBDC), are issued by the central bank and carry no credit risk. Tokenized deposits are commercial bank liabilities, covered by deposit insurance up to statutory limits, and preserve the two-tier monetary system — the structure in which central banks issue base money and commercial banks hold deposits and extend credit.

This article explains how the two instruments differ at a structural level, compares their technical architectures and design features, maps verified live deployments, and identifies the regulatory and risk landscape across five major jurisdictions. The goal is a clear, evidence-based understanding of what separates a CBDC from a tokenized deposit — and why that difference has consequences for banks, regulators, businesses, and anyone who holds a bank account.

What Are CBDCs and Tokenized Deposits and How Do They Differ at a Fundamental Level?

A central bank digital currency (CBDC) is a direct liability of a central bank, denominated in the national unit of account and backed by sovereign authority. It is the digital equivalent of a physical banknote — government-issued, risk-free from a credit perspective, and settled on central bank infrastructure. A tokenized deposit, by contrast, is a digital token issued by a regulated commercial bank that represents a 1:1 claim on an existing fiat deposit held at that institution.

Tokenized deposits preserve the traditional two-tier monetary system — the structure in which central banks issue base money and commercial banks hold deposits and extend credit. The commercial bank mints a blockchain token equal in value to the customer's deposit, while the underlying obligation remains on the bank's balance sheet. This differs fundamentally from a CBDC, where the central bank itself is the obligor and no commercial bank intermediary stands between the issuer and the holder.

Both instruments are distinct from cryptocurrencies and stablecoins. A helpful analogy: a CBDC is government-issued digital cash — the digital version of a banknote printed by the Treasury — while a tokenized deposit (also called a bank token) is an existing bank account balance placed on a programmable blockchain rail. Neither derives its value from an algorithm or an external reserve pool; both are claims on regulated institutions operating under existing monetary frameworks.

How Do CBDCs and Tokenized Deposits Compare Across Key Design Features?

Five design dimensions determine how each instrument functions in practice: issuer identity, user access, deposit insurance coverage, interest-bearing capacity, and programmability. Retail CBDCs are accessible to households and businesses, while wholesale CBDCs are restricted to licensed financial institutions for large-value settlement. Tokenized deposits sit within existing commercial banking relationships, meaning retail customers or institutional clients access them through their bank rather than directly through a central bank.

Deposit insurance is a critical distinction. Tokenized deposits remain on a commercial bank's balance sheet, so deposit insurance protections apply — for example, FDIC coverage up to $250,000 per depositor in the United States. A retail CBDC, as a direct central bank liability, carries no credit risk by definition and therefore requires no deposit insurance scheme. More than 50% of central banks surveyed by BIS in 2024 did not plan to pay interest on retail CBDC holdings, positioning it as a non-interest-bearing digital cash equivalent.

Programmability is a shared feature, but the implementation layer differs. Retail and wholesale CBDCs embed programmability at the central bank infrastructure level, while tokenized deposits execute programmable logic through smart contracts on the commercial bank's permissioned ledger. The table below maps all five dimensions across the three instrument types.

What Is the Difference Between Retail and Wholesale CBDCs and Which Matters More?

The BIS 2024 survey of 93 central banks found that wholesale CBDC development is at a more advanced stage globally than retail CBDC development. In advanced economies, 38% of central banks are running wholesale CBDC pilots, compared to 15% at the retail pilot stage. Both instruments serve distinct roles in the monetary system, and the practical case for each depends on the policy objective — financial inclusion for retail, settlement efficiency for wholesale.

Retail CBDCs — Digital Cash for the Public

A retail CBDC is a direct central bank liability available to households and businesses for everyday payments. It functions as programmable digital cash — a sovereign-issued instrument designed to replace or supplement physical banknotes. Key policy objectives include expanding financial access for unbanked populations, reducing cash handling costs, and enabling programmable government disbursements. Three jurisdictions have fully launched live retail CBDCs as of end-2024: the Bahamas (Sand Dollar, launched October 2020), Jamaica (JAM-DEX, launched July 2022), and Nigeria (eNaira, launched October 2021).

Wholesale CBDCs — Settlement Tools for Financial Institutions

A wholesale CBDC — referred to as tokenized reserves by the IMF, on the basis that interbank reserves already exist in digital form and the technology is the only substantive change — is central bank digital money restricted to licensed financial institutions. Its primary functions are settling tokenized securities through delivery-versus-payment (DvP) transactions and enabling cross-border payment-versus-payment (PvP) operations between institutions. The BIS 2024 survey found that preserving the role of central bank money as a risk-free settlement anchor — particularly as tokenized private assets proliferate — is a primary driver behind wholesale CBDC development. In this context, wholesale CBDCs act as a complement to tokenized deposits rather than a competing instrument: the commercial bank mints the deposit token, while the central bank provides the settlement asset that clears it.

How Does the Technical Architecture of CBDCs and Tokenized Deposits Function on Blockchain?

Two foundational architectural choices shape every CBDC and tokenized deposit deployment: the access model (token-based versus account-based) and the system tier (one-tier versus two-tier). In a token-based CBDC, users hold bearer-style digital tokens representing a direct monetary claim on the central bank — a model that most central banks currently prefer, partly for its AML/CFT compatibility. In an account-based CBDC, the central bank records credit balances on its own books, resembling a traditional bank account held at the central bank rather than a commercial bank.

Tier structure determines whether commercial banks remain in the chain. A one-tier retail CBDC lets the central bank issue directly to individuals, effectively bypassing commercial banks. A two-tier CBDC uses licensed intermediaries — commercial banks or payment service providers — to distribute and manage CBDC wallets, while settlement finality still rests on the central bank ledger. Tokenized deposits are inherently two-tier instruments: the commercial bank mints the token on its own permissioned ledger, and settlement of interbank obligations uses wholesale CBDC or central bank reserves as the risk-free anchor. Smart contracts on the bank's permissioned distributed ledger technology (DLT) — a shared digital record maintained across multiple authorized nodes — execute programmable payment conditions automatically and without a central authority processing each instruction.

The table below maps five live architectures across these dimensions, drawing on BIS project documentation and IMF fintech research.

What Are the Main Benefits of CBDCs and Tokenized Deposits for Payments and Finance?

CBDCs and tokenized deposits share core efficiency gains — 24/7 settlement, atomic transaction execution, and programmable payment logic — but each instrument delivers distinct advantages shaped by its issuer and the population it serves. Framing their benefits as complementary, rather than competing, reflects how most central banks and commercial banks currently position the two instruments in practice.

Benefits of CBDCs:

• Financial inclusion: Retail CBDCs can reach unbanked populations without requiring a commercial bank relationship, reducing access barriers that include minimum balance requirements and identity documentation costs
• 24/7 settlement finality: CBDC transactions settle directly on central bank infrastructure, eliminating the correspondent banking delays that currently add days and fees to cross-border transfers
• Monetary policy precision: A CBDC can carry an interest rate or expiry condition, giving central banks a direct transmission channel to the real economy — bypassing commercial bank intermediation lags entirely
• Reduced cash handling costs: Issuing digital cash cuts the physical production, distribution, and security costs associated with banknotes

Benefits of tokenized deposits:

• Atomic FX and securities settlement: Tokenized deposits enable delivery-versus-payment (DvP) and payment-versus-payment (PvP) transactions on a shared ledger, eliminating the settlement risk window that exists when cash and asset legs settle separately
• Collateral management automation: Smart contracts move collateral and margin automatically in real time, reducing manual reconciliation and improving capital efficiency for banks and their institutional clients
• Industry 4.0 integration: Germany's Commercial Bank Money Token (CBMT) project — a sandbox run by Commerzbank, Deutsche Bank, DZ Bank, and UniCredit alongside industrial firms Siemens and Evonik — reached pre-production trials in early 2026 and demonstrated machine-to-machine payment use cases where robots automatically settle payments for services rendered on DLT networks
• Smooth adoption curve: Tokenized deposits preserve existing bank-customer relationships, meaning businesses and retail users access programmable money through familiar banking interfaces rather than new central bank wallets

What Are the Primary Real-World Use Cases and Deployments of CBDCs and Tokenized Deposits?

Live deployments demonstrate that tokenized deposits have moved furthest into production as of early 2026, while wholesale CBDC projects remain primarily at the pilot and minimum-viable-product stage. Retail CBDC deployments outside the three fully launched jurisdictions — Bahamas, Jamaica, and Nigeria — are still in preparation or pilot phases, with the Digital Euro potentially reaching first issuance no earlier than 2029. The use cases across both instrument types cluster around four domains: cross-border payments, securities settlement, collateral management, and programmable supply-chain transactions.

JP Morgan's Kinexys platform processes approximately $5 billion in daily tokenized deposit transactions as of late 2025, supporting institutional clients including Siemens, BMW, CMC Markets, and Ant International in 24/7 cross-border FX settlement across five currencies — USD, EUR, GBP, CNH, and HKD. BNY launched its tokenized deposit service on 8 January 2026, enabling on-chain mirrored representations of institutional client cash balances on its private permissioned blockchain, with early participants including ICE, Citadel Securities, Ripple Prime, and Circle. Citi Token Services expanded in November 2025 to include Euro transactions and cross-border USD clearing, enabling 24/7 multibank instant payments for institutional clients across Citi and non-Citi accounts simultaneously.

How Do CBDCs and Tokenized Deposits Preserve or Disrupt the Two-Tier Banking System?

The two-tier monetary system — in which central banks issue base money and commercial banks hold deposits, extend credit, and allocate capital — underpins modern financial intermediation. A retail CBDC held directly at the central bank creates a structurally new alternative to commercial bank deposits, raising the risk of bank disintermediation: the migration of deposits away from commercial banks into central bank-held CBDC accounts. In stress scenarios, the speed and low friction of digital transactions could accelerate this migration into a self-fulfilling digital bank run — a risk that physical cash does not pose at the same scale, since cash cannot be held in large volumes instantaneously.

Disintermediation directly threatens credit creation. When commercial banks lose deposits, their capacity to fund loans contracts, reducing the flow of credit to households and businesses and weakening monetary policy transmission. The Dallas Fed's 2022 working paper identified two CBDC design parameters — the fixed cost of CBDC usage and the interest rate paid on CBDC holdings — as the primary levers controlling the scale of disintermediation. Setting CBDC holding limits is the most commonly proposed mitigation: BIS research finds that a suitably calibrated holding limit can contain fast disintermediation while preserving the financial inclusion and competition benefits that a retail CBDC provides.

Tokenized deposits do not carry this structural risk. Because they remain liabilities on the commercial bank's balance sheet, tokenized deposits preserve the two-tier system intact — customers hold a digital token, but the underlying deposit obligation stays within the bank and within existing fractional reserve frameworks. The IIF confirmed in March 2026 that tokenized deposits, where issued by insured depository institutions, should retain deposit insurance coverage under current frameworks — a stabilising advantage that CBDCs, as central bank liabilities, inherently do not require and stablecoins structurally cannot access. The Oxford Law Faculty's March 2026 analysis concluded that these layered protections — prudential regulation, deposit insurance, and central bank liquidity access in stress — give tokenized deposits a durable stability advantage in any jurisdiction where commercial banks remain the primary credit intermediaries.

What Regulatory Frameworks Currently Govern CBDCs and Tokenized Deposits Across Jurisdictions?

Regulatory approaches to CBDCs and tokenized deposits diverge sharply across jurisdictions, reflecting each region's monetary policy priorities, financial stability concerns, and political environment. The United States has explicitly prohibited federal development of a retail CBDC — President Trump's January 2025 executive order revoked the prior Biden-era CBDC exploration mandate and banned federal agency support for a retail CBDC on privacy and private-sector displacement grounds. By contrast, the EU and UK are actively building the regulatory foundations for both instruments, while China operates the world's most advanced large-scale retail CBDC pilot under full state control.

Tokenized deposit regulation is advancing fastest in jurisdictions where banking law already provides a workable foundation. The FDIC's April 2026 proposed rule under the GENIUS Act confirmed that tokenized deposits satisfying the statutory definition of a "deposit" under the Federal Deposit Insurance Act will be treated identically to traditional deposits — including full deposit insurance protection — while stablecoins backed by deposits will not receive pass-through FDIC coverage. In the UK, the Bank of England clarified its position in 2023 and reaffirmed it in 2025: deposit-taking entities may issue digital money in tokenized deposit form within existing banking regulation, and UK Finance's Global Beta Tokenised Deposit (GBTD) pilot — running until mid-2026 — is testing live fungible tokenized sterling deposits for securities settlement, digital gilt issuance support, and cross-border use cases. The EU's MiCA regulation, fully applicable from end-2024, governs stablecoins and crypto-asset services but does not directly regulate tokenized deposits, which remain within existing banking and payment services law.

How Do CBDCs and Tokenized Deposits Handle Privacy, Security, and User Data Protection?

Privacy architecture differs fundamentally between CBDCs and tokenized deposits because their data ownership structures differ. An account-based CBDC requires users to authenticate through a digital identity (ID) scheme — the BIS 2021 Annual Report chapter on CBDCs explicitly states that account-based design is rooted in verifying users' identities tied to a digital ID, and that while privacy from commercial parties is achievable, it requires deliberate architectural safeguards to prevent government transaction surveillance. A token-based CBDC mimics cash more closely by allowing bearer-style access without persistent identity linkage per transaction, but central banks still require identity verification at the wallet level to meet anti-money laundering (AML) and know-your-customer (KYC) obligations. The IMF's 2024 fintech note on CBDC data use confirmed that poorly designed CBDC data governance creates systemic privacy risks — including data leakage, unauthorized profiling, and state misuse of transaction records.

Tokenized deposits carry a different privacy profile. Because commercial banks already operate within established KYC and AML frameworks, tokenized deposits sit on permissioned ledgers with access restricted to whitelisted counterparties — eliminating the public blockchain transparency risk while retaining regulatory compliance. JP Morgan's Kinexys deployment uses strict address whitelisting and permissioned access controls, with zero-knowledge proof (ZKP) schemes under active development to allow transaction validation without revealing individual position details to external observers. Programmability introduces a dual-edged risk for both instruments: the same smart contract logic that enables legitimate conditional payments — such as programmable tax withholding or targeted stimulus disbursement — can, if poorly governed, enforce spending restrictions that erode monetary freedom without legislative oversight.

Post-quantum cryptography presents a forward-looking security challenge specific to CBDC wallet infrastructure. Classical asymmetric encryption algorithms, including RSA and elliptic-curve cryptography, are vulnerable to quantum computing attacks — a threat that becomes acute when a user's public key is exposed during an in-motion transaction on a CBDC ledger. The World Economic Forum's 2024 analysis recommended that central banks conduct a cryptographic bill of materials (CBOM) audit, catalogue all in-use encryption mechanisms, and begin transitioning to post-quantum cryptography (PQC) algorithms before quantum-capable adversaries reach cryptographic break capability. Tokenized deposits on permissioned enterprise ledgers face the same long-term quantum risk but benefit from shorter upgrade cycles — commercial banks can update cryptographic primitives within their controlled infrastructure without requiring a coordinated central bank system migration.

What Risks and Challenges Should You Consider When Evaluating CBDCs Against Tokenized Deposits?

Neither CBDCs nor tokenized deposits are risk-free instruments. Five categories of risk apply across both: disintermediation, DLT and smart contract failure, monetary policy transmission distortion, interoperability fragmentation, and privacy and governance failure. The IMF's April 2026 tokenized finance note warned that tokenization causes stress events to unfold faster than in traditional systems — tight smart contract interdependencies can amplify contagion and leave less time for regulatory intervention. The FSB's October 2024 report on the financial stability implications of tokenization identified liquidity mismatch, leverage amplification, interconnectedness, and operational fragility as the primary systemic vulnerabilities — particularly if tokenized markets scale rapidly before adequate oversight frameworks exist.

Disintermediation risk is asymmetric: it bears heavily on retail CBDC design and minimally on tokenized deposits. As covered in Section 10, the Dallas Fed's 2022 model confirmed that retail CBDC design parameters — holding limits and interest rates — directly determine how much deposit funding commercial banks lose. Monetary policy transmission risk is specific to CBDCs: the ECB's research found that a retail CBDC paying zero interest, without a sufficiently tight holding cap, can produce a "reversal interest rate" — a level below which further policy rate cuts tighten financial conditions rather than loosen them, perversely undermining monetary easing. Interoperability fragmentation affects both instruments equally. The Cambridge Centre for Alternative Finance's February 2026 report identified cross-platform connectivity as the critical barrier to scaling tokenized money — most DLT platforms cannot exchange data with each other or with legacy financial infrastructure, and no universally accepted interoperability standard exists as of April 2026.
