Blockchain can improve access to some financial services, especially cross-border payments, but it does not make finance inclusive by itself. A person still needs a usable device, connectivity, a way to fund and spend or cash out a digital asset, and protection when something goes wrong. The best case for blockchain is as one possible payment and settlement rail inside a broader, regulated service—not as a substitute for the institutions and safeguards that turn access into useful financial inclusion.
What financial inclusion means
Financial inclusion is more than opening a wallet or recording a blockchain address. It means people can access and use appropriate financial services on fair, affordable and reliable terms, with meaningful safeguards. Those services include payments and transfers, savings, credit, insurance, investment, secure stores of value, and the receipt of wages or government assistance.
- Access: A service is available and reachable to the people who need it.
- Usage: People can and do use it for real financial needs, not just sign up.
- Quality: It is affordable, reliable, safe and suitable for the user.
- Outcomes: It helps people manage money, withstand shocks, or participate in economic life.
That distinction matters: crypto ownership, wallet registrations and transaction volume do not, by themselves, show that underserved people gained useful services or improved financial security.
How blockchain could improve access
A blockchain is a shared digital ledger that records transactions. In a payment example, a sender funds a wallet, a digital asset moves over a ledger, and a recipient receives it. The recipient may then spend it, exchange it, or use a provider, bank, agent or merchant to convert it into local currency. The ledger is only one part of that customer journey.

Less settlement friction and continuous operation
A shared ledger can help parties coordinate transactions without maintaining a direct account relationship with every counterparty. In some designs this may reduce reconciliation or intermediary steps. Public networks can also operate around the clock, which may be useful when conventional services are closed. Neither feature guarantees a lower fee or faster end-to-end service: the wallet, exchange, compliance checks, foreign-exchange conversion and cash-out can still add time and cost.
Programmable payments
Smart contracts can execute rules such as releasing escrow after a condition is met, distributing payroll or aid, collecting recurring payments, or paying an insurance claim. Automation can reduce manual processing when rules and data are sound. It cannot decide whether a rule is fair, correct a bad input, or ensure a user can appeal a mistaken or harmful outcome. A useful product needs a clear route for correction and recourse.
Portability and participation
A wallet may let a user hold an asset and connect to more than one service without opening a separate conventional account for every interaction. That portability can reduce dependence on a single platform. But “open” access does not remove identity checks, sanctions screening, exchange controls, network fees, local restrictions, or the risk of losing access through a compromised or unrecoverable wallet.
Where blockchain may be useful
Cross-border remittances
Remittances can pass through several intermediaries and incompatible payment systems. The World Bank says the average cost of sending money home remains around 6% on its financial inclusion topic page. Blockchain-based settlement may reduce one part of the process, but the amount a customer actually pays can also include cash-in and cash-out, foreign exchange, agent commissions, compliance, wallet and network charges, customer support, and taxes or licensing-related costs. A cheap on-chain transfer is not necessarily a cheap remittance.
For a recipient who needs cash or local currency, the decisive question is whether a trusted, accessible payout channel exists. If conversion is expensive or unavailable, faster settlement between digital wallets may not solve the household’s problem.
Stablecoins and digital dollars
Stablecoins are privately issued or protocol-based tokens designed to track a reference asset, often a fiat currency. They may let people transfer a dollar-linked token across borders or hold it where local money is unstable. That possibility should be separated into four questions: can a person acquire and transfer the token; can they redeem it into fiat; does it remain redeemable at par; and what legal protections apply if the issuer or service fails?
Circle says USDC is redeemable one-to-one for U.S. dollars for qualified Circle Mint customers and that its reserves are backed by cash and cash-equivalent assets. That is an issuer statement, not a government deposit guarantee or proof that every retail holder can redeem directly on those terms. Stablecoins also carry issuer, reserve, redemption, regulatory, operational and cyber risks. The BIS says current stablecoin designs fall short of foundational monetary properties such as singleness and par convertibility, despite potential for faster and programmable payments: Annual Economic Report 2026, Chapter III.
There is also a currency-policy trade-off. A dollar-linked token can offer a hedge against local currency weakness, while wider use may encourage dollarization and complicate monetary policy. A 2026 BIS paper estimates that approximately 98% of stablecoin value is dollar-denominated: The impact of stablecoins on the international monetary and financial system. The IMF likewise describes potential payment benefits alongside the need for safeguards against currency substitution, capital-flow problems, fiscal risks and financial-integrity failures: How Stablecoins Can Improve Payments and Global Finance.

Stablecoin rails may help a business pay an overseas contractor or receive money from a foreign customer without waiting on conventional bank transfers. Their practical value depends on what the recipient can do next: spend the asset, exchange it at a fair rate, or cash out locally.
Programmable disbursements and shared records may also support aid or government payments by making flows easier to trace. But auditability does not eliminate fraud or guarantee that assistance reaches the intended person. Public transaction histories can expose sensitive activity; mistaken transfers, identity mismatches and technical requirements can exclude recipients. Assistance should not depend on adopting a particular technology when accessible alternatives are needed.
Tokenized assets
Tokenization can represent fractions of an asset or financial instrument digitally, potentially lowering some participation barriers. A token that represents a fraction is not automatically a legally enforceable ownership claim, easy to sell, or appropriate for a low-income investor. Asset and market risk, custody, liquidity and legal complexity remain.
Decentralized finance
Decentralized finance (DeFi) uses blockchain-based protocols to offer services such as lending, trading or yield products. Open access can be appealing, but it is not the same as a protected bank account or a suitable savings product. Risks include smart-contract bugs, oracle failures, collateral liquidation, variable yields, governance problems, irreversible transfers, manipulation and limited legal recourse. The BIS notes that DeFi can reproduce familiar financial risks while adding information asymmetries, market inefficiencies and cryptoization risks in emerging markets: Cryptocurrencies and decentralised finance.
Rank #4
Blockchain, Bitcoin, stablecoins and CBDCs are not the same thing
Blockchain describes a way of recording and coordinating transactions; it does not specify who issues an asset, what it is worth, or what rights a holder has. These distinctions matter when judging an inclusion claim.
| Instrument | Who issues or governs it? | Possible inclusion role | Key concern |
|---|---|---|---|
| Bitcoin | A decentralized network maintains the system; no central issuer promises redemption. | Open access to a cryptoasset network. | Price volatility makes it difficult to rely on for everyday spending or savings. |
| Stablecoin | Typically a private issuer or protocol, depending on design. | Digital transfer of a token designed to track a reference asset. | Redemption, reserve, issuer, regulatory and currency-substitution risks. |
| CBDC | A central bank issues digital central-bank money. | Could be designed for low-fee payments and access without a conventional bank account. | Access, privacy, infrastructure and adoption depend on design and local conditions. |
| Tokenized deposit | Usually a regulated bank represents a deposit digitally. | Could support programmable transfers using a bank deposit claim. | Holders still depend on the bank and the applicable legal protections. |
| DeFi asset or claim | A protocol or smart contract determines the rules; legal rights vary. | May provide access to open financial applications. | Contract, market, oracle, governance and recourse risks. |
A CBDC is not a stablecoin or a public cryptocurrency. The IMF says a CBDC could be designed to offer payment access without a bank account, low or no fees, and less stringent identity requirements for low-risk users. It also stresses that a CBDC does not by itself solve gaps in digital literacy, electricity, connectivity or network access: IMF CBDC Virtual Handbook.
What the evidence does—and does not—show
Digital financial services can improve affordability, speed, security and transparency for underserved users, according to the World Bank. Those benefits are broader than blockchain: they can come from mobile money, fintech and other digital systems too. The World Bank’s roughly 6% remittance-cost figure describes the average cost of sending money home, not the cost of every route or the amount a blockchain product will save.
Evidence from El Salvador is a caution against treating cryptocurrency adoption as proof of inclusion. An IMF assessment of the period it examined found no visible improvement in financial inclusion or digital remittances from the country’s Bitcoin legal-tender policy, and no evidence of a beneficial Bitcoin use case for the unbanked population in that context: El Salvador: Selected Issues. That finding is specific to the policy and period assessed; it does not establish that every blockchain payment application will fail.
Best Value
For any project, evidence of sustained use and better outcomes among the intended users is more informative than wallet counts or transaction volume, which can also reflect trading, institutional transfers or automated activity. The IMF’s 2025 Financial Access Survey treats technologies including fintech, mobile money, blockchain, stablecoins and biometric security as part of a wider financial-access ecosystem, rather than a single winning technology.

- Devices and connectivity: A smartphone, data plan, reliable electricity and network access may be unavailable or unaffordable. Continuous internet dependence is a weakness during outages, disasters or in remote areas.
- Identity and compliance: A person may create a permissionless wallet, yet still need formal identification to buy assets, use a regulated provider or cash out. Proportionate checks matter when users lack standard documents.
- Cash and local acceptance: Receiving a digital asset is not enough if nearby merchants do not accept it and no trusted agent or provider can convert it into local spending power.
- Complexity and recovery: Seed phrases, network selection, gas fees and addresses can confuse new users. Self-custody offers control but makes security and recovery the user’s responsibility; custodial wallets can be simpler but depend on a provider that may freeze accounts or fail.
- Fraud and irreversible errors: Blockchain does not prevent phishing, fake wallets, social engineering, theft, malicious contracts or a transfer to the wrong address. Some transactions cannot be reversed through a bank-style dispute process.
- Volatility and redemption: Bitcoin and other unbacked cryptoassets can lose value sharply. Stablecoins avoid some price fluctuation but rely on an issuer, reserve and redemption process, and can face depegging or restricted access.
- Privacy: Public ledgers can leave transaction histories visible or linkable. Exposure can threaten migrants, vulnerable households, political dissidents and small businesses.
- Unequal access: Phone ownership, identity documents, disability access and financial decision-making can vary by gender, age, migration status and location.
- Legal uncertainty: Rules can affect whether a person may hold, exchange, spend or redeem an asset. Compliance obligations may also raise the cost of a service.
When an existing alternative may work better
Blockchain should be compared with mobile money, instant-payment systems, e-money, agent banking, bank-fintech partnerships, conventional remittance providers, cards, digital identity systems and CBDCs. In some markets, mobile money already provides a simpler way to pay and transfer funds. A blockchain design is worth the added complexity only if it brings a material benefit—such as useful cross-border interoperability, programmable settlement or access to an asset unavailable on existing rails—and does so without worsening cost, safety or usability.
The practical question is not whether blockchain is newer or more “advanced,” but which system delivers the lowest-cost, safest and most usable service for the target population under local conditions. Public networks offer open participation but can expose users to fee volatility, congestion and visible transactions. Permissioned networks can provide more control and privacy, but depend more on institutions. Self-custody and custodial wallets likewise trade user control against easier recovery and provider dependence.
A checklist for judging an inclusion project
- Name the user: Is the product for unbanked households, migrants, merchants, aid recipients, freelancers or financial institutions?
- Define the problem: Is the unmet need high remittance fees, slow settlement, access to savings, limited credit, weak records or something else?
- Calculate the full cost: Include onboarding, network, exchange, cash-in and cash-out, compliance, withdrawal and support costs.
- Test local usability: Can users transact in local currency and reach a trusted cash-out or merchant network?
- Check access conditions: What are the device, connectivity and identity requirements? Is low-bandwidth, offline or agent-assisted service available?
- Establish responsibility: Who handles mistaken payments, fraud, lost keys, complaints and provider insolvency?
- Assess asset risk: Is the asset volatile, dependent on an issuer, redeemable in practice, or exposed to local-currency risks?
- Understand data exposure: What transaction data is public, retained, shared or potentially linked to a person?
- Check interoperability and legality: Can users move funds between wallets, banks, payment systems and chains? Are the providers and flows authorized in the relevant jurisdiction?
- Demand outcome evidence: Are underserved users making sustained use of the product and benefiting, or is success measured only by registrations and volume?
A project that cannot answer the last-mile questions—funding, spending, conversion, recovery and recourse—has not yet demonstrated financial inclusion, regardless of its underlying ledger.
