Central Bank Digital Currencies and Financial Inclusion: the case of Nigeria's eNaira

Nigeria’s eNaira was designed to widen access to digital money, but its early record shows that availability alone does not create inclusion. Launched in October 2021 as one of Africa's first CBDCs, eNaira has faced challenges in achieving widespread adoption and fostering true financial inclusion.

Early figures on wallets, minting, and issuance do not necessarily show regular use by unbanked people. Instead, the data suggests that the digital currency is primarily being used by those who already have access to traditional banking services, indicating a gap in reaching the unbanked population.

Understanding CBDCs and the eNaira

A central bank digital currency sits at the intersection of public money and digital payments. Nigeria’s eNaira was presented as a way to extend the reach of central bank money while supporting a broader move toward electronic transactions. Its promise is significant, but the test is practical: whether people who remain outside formal finance can use it easily and regularly.

What a central bank digital currency is

A CBDC is a digital form of a country’s official currency issued by its central bank. Unlike a commercial bank deposit, it represents a direct claim on the central bank, while unlike cash, it is held and transferred through digital infrastructure. A retail CBDC is intended for everyday users rather than only financial institutions.

The policy case usually rests on access, payment efficiency, resilience, and the possibility of reaching people who are poorly served by existing institutions. Yet those benefits depend on distribution, identity systems, connectivity, and public confidence. A digital currency does not remove those conditions; it makes them part of the payment experience.

How the eNaira differs from cash, bank deposits, and cryptocurrencies

Cash can be used without a device or network, although it is costly to transport and difficult to use remotely. Bank deposits are managed through regulated institutions and are connected to established accounts, payment services, and customer support. The eNaira, by contrast, is a digital representation of the naira within a system overseen by the Central Bank of Nigeria.

Cryptocurrencies differ in their issuance, governance, and price stability. The eNaira is sovereign money, denominated in naira, and intended for payments rather than speculative trading. That distinction matters for inclusion because users need to understand both what the instrument is and what it is not before they will trust it with household income or business receipts.

The eNaira’s launch, structure, and policy objectives

Nigeria launched the eNaira on October 25, 2021, making it one of Africa’s earliest CBDCs. Public descriptions of the system identify a two-tier structure in which regulated financial institutions and registered agents help distribute and support access. The early model focused on person-to-person and person-to-business payments, with separate wallet arrangements for individuals and merchants.

The policy objectives were broader than replacing notes and coins. They included improving access to central bank money, supporting a resilient payment system, encouraging inclusion, reducing the cost of processing cash, and enabling more direct welfare payments. Research on the project also discusses simplified account opening, lower-cost financial services, remittances, and possible offline access as routes toward wider participation; a useful overview is available in this eNaira CBDC research.

The role of the Central Bank of Nigeria

The Central Bank of Nigeria sets the policy direction, regulates the monetary system, and oversees the framework in which the eNaira operates. Its role is therefore not limited to issuing a digital token. It also involves setting access rules, coordinating regulated intermediaries, addressing operational risk, and explaining the public purpose of the currency.

That institutional role shapes the inclusion question. If the central bank promotes the eNaira as a public payment option, users need clear information about fees, eligibility, recourse, privacy, and how the wallet relates to existing accounts. They also need assurance that the system will work when a bank branch, agent, or reliable data connection is unavailable.

Why financial inclusion matters in Nigeria

Financial inclusion is not simply a count of people with an account. It concerns whether households and businesses can safely save, receive money, make payments, access credit, and manage financial shocks at a reasonable cost. Nigeria’s large informal economy and uneven infrastructure make that distinction especially important.

The eNaira entered a market where digital payments were already developing, but where access and trust remained uneven. That means its performance should be judged against the needs of excluded users rather than against the novelty of its technology alone.

Nigeria’s unbanked and underbanked population

Nigeria has a large population with limited or no access to formal financial services, although the exact size varies by definition, survey, and year. The underbanked may hold an account but rarely use it, rely heavily on cash, or lack access to useful products such as affordable transfers and savings tools. The unbanked may face an even more basic obstacle: no formal account through which digital money can move.

This creates a demanding test for the eNaira. A wallet registration can indicate interest or a policy contact, but it does not prove that an unbanked person has become a regular digital-payment user. Inclusion requires repeated, useful transactions and a way to convert digital balances into practical household or business value.

Barriers to accessing formal financial services

Distance, documentation, irregular income, transaction costs, limited financial knowledge, and mistrust can all discourage formal participation. For a market trader or rural household, the cost of reaching a branch may matter as much as the price of a transfer. A person with a phone may still lack stable data, a compatible device, or confidence that a failed transaction will be resolved.

Identity requirements can also create a tension between safety and access. Strong know-your-customer rules help reduce fraud and financial crime, but requirements that assume a bank account, reliable records, or easy access to formal documents can exclude precisely the people a CBDC is meant to reach.

The importance of mobile phones, agents, and digital identity

Mobile phones can provide a practical bridge into digital finance, particularly when a formal branch is far away. Agents add a human point of contact for cash-in, cash-out, registration, and troubleshooting. Digital identity systems can make onboarding more consistent, but they also raise questions about coverage, errors, and the treatment of people whose records are incomplete.

The eNaira’s access model therefore depends on more than an app. It needs a distribution network that works in villages, markets, and low-income neighborhoods, with agents who have liquidity and users who can obtain support. A payment system that works only for digitally confident smartphone owners will have limited inclusion value.

How digital payments can support households and small businesses

Digital payments can help households receive wages, remittances, social transfers, or other income without travelling with cash. For small businesses, electronic records may make it easier to track sales and demonstrate activity to a financial provider. Those benefits are possible only when transactions are affordable, reliable, and accepted by the people on both sides of a payment.

The broader policy discussion is captured in this CBDC inclusion analysis, which places payment efficiency alongside unresolved questions about access and the effects of new digital infrastructure. For Nigeria, the practical measure is whether digital payments reduce friction in ordinary transactions rather than merely increase the number of registered users.

How the eNaira could expand financial access

The case for the eNaira rests on several possible channels of inclusion. It could offer a public digital payment instrument, lower some transaction costs, and create new routes for government or private transfers. It could also make participation easier for people who do not want, or cannot yet obtain, a conventional bank account.

These are possibilities, not automatic outcomes. Each depends on design choices, user demand, merchant acceptance, and the ability of the system to connect with the financial services people already use.

Lower-cost digital payments for underserved users

A CBDC may reduce some costs associated with handling, transporting, and settling physical cash. Direct digital transfers can also shorten the chain between sender and recipient. For low-income users, however, even small data charges, agent fees, or failed-transaction costs can outweigh the theoretical savings.

The eNaira’s inclusion case is strongest where it makes a familiar payment cheaper or more dependable. It is weaker if users must maintain several wallets, learn unfamiliar procedures, or pay for access to a network that merchants do not accept.

Wallets and access for people without traditional bank accounts

Wallets can provide a simpler entry point than a full bank relationship. A tiered approach to onboarding may allow lower-risk users to begin with limited functionality and expand access as their identity information is verified. This can be useful for people who have phones but little contact with formal financial institutions.

Still, the distinction between a wallet and an account should not be overstated. Users need somewhere to obtain funds, spend them, withdraw cash when necessary, and resolve disputes. Without agents, merchants, and usable links to other payment channels, a wallet can remain technically available but economically isolated.

Government payments, remittances, and social transfers

The eNaira was also associated with the possibility of direct welfare disbursement and more efficient public payments. A digital channel could reduce handling steps and improve traceability, while remittance-related use could help recipients receive funds more directly. These applications could reach people who do not regularly visit bank branches.

They also require careful implementation. A recipient should not be forced into a difficult wallet process to access essential support, and public agencies must account for people with limited connectivity or documentation. Payments need clear communication, accessible complaint channels, and a practical cash-out option.

Opportunities for merchants, farmers, and small businesses

Small businesses may benefit from faster person-to-business payments and more reliable records. Farmers and informal traders could use digital transfers when buyers, cooperatives, or public programs offer them a clear reason to do so. The benefit grows when the payment tool fits existing routines instead of requiring a separate financial habit.

That is why merchant acceptance is central. A shopkeeper may register for a wallet but continue to prefer cash if customers do not ask to pay digitally, settlement is uncertain, or funds are difficult to use with suppliers. Inclusion is strongest when both sides of the transaction see a concrete advantage.

Adoption challenges facing the eNaira

The eNaira’s early adoption has drawn criticism because public availability has not translated into evident everyday use at the scale expected from a national payment initiative. Initial launch reporting cited 500 million eNaira minted and 200 million issued to banks, but those figures describe supply and distribution, not the number of active unbanked users. Later assessments have likewise warned against treating wallet registrations as proof of sustained inclusion.

A field-focused eNaira research account describes low cash displacement, trust concerns, and mixed perceptions of the reliability, security, accessibility, and interoperability of digital payment systems. Those criticisms do not prove that the model cannot work, but they show why adoption must be assessed through behavior and outcomes.

Limited awareness and user trust

Many potential users may not understand why they need an eNaira wallet when cash and other electronic payment methods already meet immediate needs. Awareness campaigns can explain the product, but trust is built through successful transactions, transparent charges, responsive support, and consistent availability.

Trust also has an institutional dimension. Users may worry about errors, frozen balances, or whether a public digital currency gives them meaningful control over their money. A new payment instrument must earn confidence one transaction at a time, especially among people who have experienced unreliable financial services.

Internet access, smartphones, and digital literacy gaps

A smartphone application and dependable data connection are not universal conditions. Rural communities, older users, people with basic phones, and households managing expensive data access may find a digital wallet difficult to use. Even when the technology is available, unfamiliar interfaces can create mistakes and dependence on intermediaries.

These constraints make offline or low-connectivity functions particularly relevant. They also reinforce the need for agents, simple menus, local-language support, and assistance that does not assume a high level of digital literacy.

Competition from mobile money and existing payment platforms

The eNaira is not entering an empty market. Banks, fintech services, card networks, mobile money providers, and informal payment practices already give people ways to move funds. Users will compare the new wallet with tools they know, including the availability of merchants, speed of transfers, costs, and the ease of recovering an account.

This competition is not necessarily a policy failure; it is a test of value. The eNaira needs a distinct public purpose or a clear practical advantage if it is to change established behavior. Interoperability may matter more than trying to make users abandon every existing channel.

Concerns about privacy, surveillance, and cybersecurity

A digital payment system can create records that cash does not. That may support fraud prevention and accountability, but it can also prompt legitimate concerns about surveillance, data sharing, and misuse. Cybersecurity risks add another layer, since outages or compromised accounts can affect confidence across the system.

Privacy rules must therefore be understandable, enforceable, and matched by meaningful redress. Users need to know what information is collected, who can access it, how long it is retained, and what happens when a transaction is disputed. These protections are part of inclusion because people who fear the system may simply avoid it.

Evidence of the eNaira’s impact on financial inclusion

The central question is not whether Nigeria created a CBDC. It is whether the eNaira has reached people who were previously excluded and improved the way they receive, store, or spend money. Evidence so far points to a gap between the ambition of the project and the limited public visibility of regular, broad-based use.

That gap calls for more careful measurement rather than a simple verdict. Adoption can be overstated by counting every download, registration, or funded wallet, while impact can be understated if narrow but valuable uses are ignored.

Measuring adoption beyond wallet registrations

A serious assessment should separate registered wallets from verified users, funded wallets, active wallets, and recurring users. It should also identify whether users were previously unbanked, underbanked, or already active in digital finance. Without that segmentation, a large headline number may conceal little change in financial access.

Useful measures should connect usage to outcomes. They might examine transaction frequency, merchant acceptance, average balances, failed payments, cash-out patterns, and the geographic and demographic distribution of activity. The point is not to reward a higher number by itself, but to establish whether the system is being used for meaningful economic activity.

Transaction activity and everyday usage patterns

Transaction data can reveal whether the eNaira is used for groceries, transport, wages, remittances, government transfers, or occasional demonstrations. A wallet used once during onboarding has a different inclusion value from one used weekly by a market trader. Public reporting should distinguish these patterns while protecting personal privacy.

The early supply figures provide useful context but not a complete adoption picture. Minting and issuance show that the infrastructure was funded and distributed; they do not establish whether recipients used it repeatedly or whether transactions expanded access for people previously outside formal finance.

Inclusion outcomes for rural and low-income communities

The strongest evidence would come from rural and low-income users who can identify a specific improvement: lower transfer costs, fewer trips to a branch, safer receipt of income, or easier participation in a formal payment. Surveys and field studies should ask about these changes directly rather than infer them from wallet totals.

Geographic coverage also matters. National averages can hide areas where network access, agent liquidity, or identity registration remains weak. If usage is concentrated among urban, banked, and digitally experienced customers, the eNaira may be expanding digital payments without substantially narrowing financial exclusion.

What early research and field evidence reveal

Early research presents the eNaira as capable of supporting simplified access, lower-cost services, direct transfers, and offline channels. Field evidence is more cautious, pointing to cash persistence, low trust, and concerns about reliability and interoperability. Taken together, these findings suggest that the inclusion case remains conditional rather than proven.

The fairest conclusion is that Nigeria has demonstrated the feasibility of launching a retail CBDC, but not yet a decisive solution to exclusion. The next stage should prioritize transparent usage data and independent evaluation, especially among the communities the currency was meant to serve.

Policy and design choices that could improve inclusion

The eNaira’s future impact will depend less on its label as a CBDC than on the details of access and use. Policymakers can improve the chances of inclusion by reducing technical friction, connecting the system to existing providers, and protecting users from avoidable harm. These are implementation questions, but they determine whether the public purpose reaches real communities.

Design should also remain adaptive. A feature that works for urban smartphone users may fail in a rural market, while a rule designed for fraud prevention may inadvertently exclude people with incomplete records.

Offline functionality and low-connectivity payments

Offline payments could address one of the clearest barriers to digital inclusion: unreliable connectivity. A user should be able to complete limited transactions safely and have them reconciled when a connection returns. Such functionality would need carefully defined limits, fraud controls, and clear instructions for users and agents.

The case for offline access is strongest where people already have phones but cannot depend on continuous data service. It should complement, not replace, investment in network coverage and agent infrastructure. A poor connection should not turn a basic payment into a confusing exception process.

Interoperability with banks, fintechs, and mobile money

Interoperability can make a CBDC more useful by allowing people to send and receive funds across the channels they already use. It can also reduce the need for merchants to maintain separate systems. The policy goal should be a connected payment environment in which users are not trapped inside one wallet.

That approach may be more realistic than expecting the eNaira to become the sole digital payment method. Open technical standards, fair settlement arrangements, and consistent consumer protections can encourage providers to connect while preserving the central bank’s oversight of the currency.

Tiered know-your-customer requirements

Tiered KYC can allow people with lower transaction limits to begin using basic services with fewer documentation burdens. As usage or limits increase, additional verification can be required. This structure can balance access with safeguards, provided the entry tier is genuinely usable and not merely theoretical.

The design must include clear escalation paths when records do not match or a user lacks a required document. Agents should be trained to explain the rules rather than reject applicants without recourse. Inclusion improves when compliance is proportionate to risk and supported by practical assistance.

Consumer protection and data privacy safeguards

Consumer protection should cover failed transfers, mistaken payments, fraud, account recovery, fees, and complaints. People need a predictable process for resolving problems, with responsibilities clearly divided among the central bank, financial institutions, agents, and technology providers.

A compact policy checklist can help keep inclusion goals tied to user experience:

• Publish plain-language information about fees, limits, privacy, and disputes.

• Track active and repeat use separately from registrations.

• Test access with rural, low-income, older, and low-literacy users.

• Provide offline or low-connectivity options with appropriate safeguards.

These measures would not guarantee adoption, but they would make the project easier to evaluate and safer to use. Privacy protections should be visible in practice, not left as a technical promise that ordinary users cannot understand.

The future of the eNaira and Nigeria’s digital economy

Nigeria’s experiment remains relevant because it shows both the appeal and the difficulty of using public digital money to address exclusion. The launch proved that a large emerging economy could deploy a retail CBDC, but deployment was only the first milestone. The harder work is building a reason for people and businesses to return to it.

The eNaira’s next phase should be judged by transparent evidence: who uses it, how often, for which payments, and with what measurable benefit. That standard would also help other countries separate technological achievement from financial inclusion.

Building trust through clearer value propositions

Users need a concise answer to a simple question: why should this payment method matter in my daily life? The answer might involve cheaper transfers, dependable public payments, broader access, or easier transactions in places where other options are weak. It must be demonstrated through service quality rather than slogans.

Clear communication should also acknowledge limits. Explaining when the eNaira is useful, how it differs from a bank deposit, and where support is available can reduce confusion. Honest information is more likely to build durable trust than claims that every user will benefit in the same way.

Using incentives without creating dependency

Temporary fee reductions, merchant support, or targeted public-payment programs could encourage trial. Incentives can be useful when they help users discover a lasting benefit, but they should not hide a weak product or create activity that disappears as soon as subsidies end.

Evaluation should compare incentive-driven transactions with regular use after the initial offer. Policymakers should ask whether users continue because the system is cheaper, safer, or more convenient, rather than because they are being paid to participate.

Supporting innovation through programmable payments

Programmable payments could allow funds to be used under defined conditions, such as targeted transfers or staged disbursements. That may help public programs improve delivery and monitoring, but it also increases the need for transparency and user protections. People should understand restrictions before accepting funds.

Innovation should therefore be bounded by clear policy goals. A programmable feature is valuable when it solves a real administrative or payment problem; it is not valuable simply because the technology permits it. Careful pilots and independent review can reduce the risk of building complexity that users cannot navigate.

Lessons Nigeria offers other emerging economies

Nigeria’s experience offers a practical warning to countries considering a CBDC for inclusion. Launch speed, technical architecture, and headline wallet numbers matter less than distribution, interoperability, trust, and repeated use. A CBDC should be designed around the constraints of excluded users from the beginning, not adapted to them after adoption stalls.

The broader lesson is measured ambition. Public digital money can expand the range of payment options, but it cannot by itself repair weak connectivity, incomplete identity systems, low consumer trust, or limited merchant acceptance. Those foundations determine whether a CBDC becomes a useful public utility or remains a policy experiment with modest reach.
