CBDC and Financial Inclusion: Can Digital Currency Help the Unbanked?

CBDC and financial inclusion is one of the most practical debates in digital assets because it asks a simple question: can public digital money reach people that banks, card networks, and formal lenders have not served well? The short answer is yes, but only if the system is designed around the unbanked from day one. A central bank digital currency will not fix weak identity systems, poor connectivity, low trust, or thin financial literacy on its own.

The stakes are large. Analysis built on World Bank financial inclusion data estimates that roughly 1.5 billion adults, close to a quarter of the world's adult population, remain unbanked. Hundreds of millions more are underbanked, with limited or no access to formal credit. Global Findex reporting has consistently placed the bulk of unbanked adults in a small set of countries, including Bangladesh, China, Egypt, India, Indonesia, Mexico, Nigeria, and Pakistan.

Why Financial Exclusion Persists

Financial exclusion is not just a banking problem. It is a cost problem, an identity problem, a geography problem, and often a trust problem.

Women make up a disproportionate share of the global unbanked population, and most unbanked adults come from the poorest 40 percent of households, according to World Bank Global Findex reporting. Unbanked adults are also more likely to be out of the labor force, less educated, and based in developing economies.

Here is the awkward detail: mobile phone access is already high. In many markets adult phone ownership sits near 90 percent. Yet a large share of transactions stays in cash. That tells you technology access is only part of the story. People may own a phone and still avoid formal finance because fees are unclear, account opening is hard, nearby agents are unreliable, or documentation is missing.

What Makes CBDC Different?

A retail CBDC is digital money issued by a central bank for use by households and businesses. Unlike a balance held with a private payment provider, a CBDC is a direct claim on public money, depending on the design the central bank chooses.

The International Monetary Fund has argued that CBDCs could help excluded individuals enter digital payments if they are designed to overcome access barriers. The Bank for International Settlements has described retail CBDC as a possible tool for inclusion, provided inclusion goals shape the design from the start. The core idea is that a CBDC should be treated as financial infrastructure, not just another payment app.

That distinction matters. If a CBDC simply copies bank account requirements and a smartphone-only app design, it will mainly serve people who are already connected. To help the unbanked, it has to solve the boring, difficult parts of finance.

How CBDC Can Support Financial Inclusion

Lower-cost digital payments

CBDC can cut payment costs when it is built as public infrastructure with open access for regulated providers. This does not mean every transaction is free. Someone still pays for compliance, customer support, fraud handling, and agent liquidity. But the base payment rail can be cheaper than a patchwork of private systems.

For low-income users, small fees matter. A charge that looks tiny on a corporate treasury dashboard can be enough to push a market vendor back to cash.

Simplified onboarding with tiered KYC

Tiered know your customer rules are one of the most important inclusion tools. A low-value wallet could allow basic transactions with simplified due diligence, while higher limits require stronger identity checks. BIS policy discussions often point to this model because it balances inclusion with anti-money laundering controls.

This is where implementation gets messy. In real deployments, the question that trips teams up is not whether e-KYC exists. It is what happens when a user has a valid national ID number but no proof of address, or when the biometric check fails because the phone camera is poor. If the fallback process sends that person to a distant branch, the inclusion benefit disappears.

Offline payments for rural and disaster settings

Offline CBDC is a serious design issue, not a nice extra. Rural users may face weak connectivity. People also need payments during storms, conflict, outages, or network congestion.

Offline systems require careful controls against double spending. Wallets may need secure elements, transaction counters, value limits, and delayed synchronization. These details sound technical because they are. But they decide whether CBDC works for a farmer outside network coverage or only for urban users with stable data plans.

Device flexibility

Smartphone-only CBDC is the wrong choice for a serious inclusion mandate. A better design supports basic phones, assisted transactions through agents, cards, and low-bandwidth interfaces such as USSD where appropriate.

Developers should test flows on cheap Android devices, not only flagship phones. A wallet that works well on a developer's handset can be unusable on a low-memory device with intermittent data. You find this fast when QR scanning lags, app updates are too large, or a session times out during ID capture.

Connection to government payments

CBDC wallets can be linked to social transfers, subsidies, salary payments, or emergency relief. This can create a first real use case for people who do not currently see the value of a formal account.

The design must still protect choice. Cash access should remain available for users who depend on it, and government transfers should not force people into a system they do not trust or understand.

Why CBDC Is Not a Stand-Alone Fix

To be blunt, CBDC can fail at inclusion. It can also widen the gap if better-connected users get the benefits first while the poorest users face confusing interfaces and weak support.

The IMF has cautioned that more empirical evidence is needed and that pilots should measure distributional effects on vulnerable groups. IMF research on developing economies finds that a well-designed retail CBDC can increase lending and reduce the risk of bank disintermediation, while poor design may pressure bank funding and complicate financial stability.

Key risks include:

• Privacy concerns: Users need clear rules on who can see transaction data and under what conditions.
• Cybersecurity threats: CBDC wallets and agent networks become high-value targets.
• Operational outages: Public payment infrastructure must work under stress.
• Digital literacy barriers: Complicated interfaces exclude the exact users CBDC is meant to help.
• Over-reliance on smartphones: This can leave behind older users, rural communities, and people with shared devices.

The right policy position is not CBDC versus cash. In the medium term, CBDC should coexist with cash, mobile money, bank accounts, and private payment networks. Different users need different options.

Design Choices That Matter Most

If a central bank wants CBDC and financial inclusion to connect in practice, these design choices matter more than the branding of the wallet.

1. Make inclusion a primary objective: Do not treat it as a public relations line added after the technical architecture is set.
2. Use a two-tier model: Let the central bank run core infrastructure while banks, fintechs, and non-bank providers build user-facing services.
3. Keep fees transparent: Low-income users need predictable costs, especially for small payments and remittances.
4. Build for interoperability: CBDC should work with existing payment systems, merchant tools, and ideally remittance channels.
5. Protect consumer rights: Users need fraud reporting, dispute resolution, and clear liability rules.
6. Support offline and assisted use: Agents, cards, and basic-phone options can matter as much as the mobile app.

What This Means for Developers and Enterprises

For payments developers, CBDC inclusion projects create real work: wallet UX, agent tools, offline transaction logic, fraud monitoring, identity verification, merchant acceptance, and integration with existing payment schemes. The hard part is not producing a demo. It is making the service understandable at a shop counter with a queue behind the user.

Enterprises operating in emerging markets should watch CBDC pilots closely. Payroll, supplier payments, refunds, micro-payments, and remittances may all shift if CBDC rails become part of national payment infrastructure. Compliance teams will also need to understand data protection, consumer recourse, and anti-money laundering expectations.

The Practical Outlook

CBDCs can help the unbanked when they reduce real barriers: documentation, cost, distance, connectivity, trust, and usability. They will not succeed just because the money is digital or issued by a central bank.

The most credible path is gradual. Start with low-value everyday payments. Test with underserved users before national launch. Keep cash available. Allow non-bank providers to participate under clear rules. Measure who actually uses the system, not just how many wallets were created.

Your next step: if you work in payments, policy, compliance, or digital assets, study one live CBDC pilot and map the user journey for someone with no bank account, a basic phone, and limited documentation. That exercise will show you quickly whether the design supports financial inclusion or only digitizes access for people who already had it.
