Unbanked

What Is the Unbanked Population?

The unbanked are adults who do not hold an account at any bank, credit union, or similar financial institution. They operate entirely outside the formal banking system, relying on cash, informal savings groups, and alternative financial services to manage their money. The term is distinct from "underbanked," which describes people who have a bank account but still depend on nonbank services like check cashing, payday loans, or money orders.

According to the World Bank's Global Findex 2025 report (surveyed in 2024), roughly 1.3 billion adults remain outside the formal financial system, down from 1.4 billion in 2021. Global account ownership has risen from 51% of adults in 2011 to 79% in 2024, but the remaining gap is concentrated among the world's poorest and most marginalized populations: 55% of the unbanked are women, 52% come from the poorest 40% of households, and 62% have only primary education.

Financial inclusion matters because access to basic financial services (savings, payments, credit, insurance) is a prerequisite for economic participation. Without an account, people cannot receive wages digitally, build a savings buffer, or access credit at reasonable rates. The unbanked pay a "poverty premium" through higher fees on check cashing, money orders, and informal lending.

Where the Unbanked Are

The unbanked population is not distributed evenly. More than half of the world's 1.3 billion unbanked adults are concentrated in just eight countries: Bangladesh, China, Egypt, India, Indonesia, Mexico, Nigeria, and Pakistan.

Barriers to Banking

The World Bank's Global Findex surveys ask unbanked adults why they do not have an account. The reasons reveal structural barriers, not simply lack of interest:

• Insufficient funds: roughly 62% cite not having enough money to justify an account. Traditional banks often require minimum balances of $100–$500 to avoid monthly maintenance fees of $10–$15.
• Cost: about 25% say accounts are too expensive. Monthly fees, overdraft charges, and minimum balance penalties price out low-income users.
• Geographic distance: approximately 25% say financial institutions are too far away. In rural areas, the nearest bank branch can be hours away.
• Documentation: around 20% lack the identification documents banks require. KYC requirements that assume government-issued ID exclude populations with weak civil registration systems.
• Distrust: roughly 23% do not trust financial institutions (rising to 31% in parts of Europe and Central Asia). Historical bank failures, corruption, and currency devaluations erode confidence.
• Family dynamics: about 20% say a family member already has an account. This disproportionately affects women in households where men control financial access.

Mobile Money as a Bridge

Before crypto entered the conversation, mobile money demonstrated that financial services could reach the unbanked without traditional bank infrastructure. The most significant example is M-Pesa, launched in Kenya in 2007 by Safaricom.

Before M-Pesa, fewer than 20% of Kenyan adults held bank accounts. By 2021, 84% had access to financial services. M-Pesa now serves over 66 million customers across Kenya, Tanzania, Uganda, and Mozambique, processing more than 33 billion transactions annually with a total value exceeding $450 billion: more than half of Kenya's GDP flows through the system.

MIT economists found that M-Pesa lifted approximately 2% of Kenyan households out of extreme poverty between 2008 and 2014 and increased per capita consumption by 5.4%. The gender gap in financial access narrowed from over 12 percentage points to near parity.

Mobile money proved a critical insight: the unbanked are not unbankable. Given accessible tools on devices they already own, people adopt financial services rapidly. However, mobile money systems are typically closed-loop and country-specific, creating limitations for cross-border payments and interoperability.

How Crypto and Stablecoins Address the Gap

Cryptocurrency extends the mobile money insight further: if a phone is a bank branch, then an open protocol is a payment rail that works across borders without permission from any single operator.

Dollar-Denominated Savings

In inflation-prone economies, holding local currency means watching savings erode. Argentina's inflation reached 236.7% by late 2024, and the Turkish lira lost over 80% of its value since 2020. Stablecoins like USDC and USDT provide dollar-denominated savings accessible from a smartphone, without requiring a U.S. bank account or navigating foreign exchange controls. In Argentina, 61.8% of crypto transactions involve stablecoins, often used as a savings mechanism rather than a speculative instrument.

Low-Cost Remittances

The global average cost of sending remittances through legacy systems is 6.36%, meaning a worker sending $200 home loses roughly $13 to fees. Stablecoin payment rails typically charge under 1%, with on-chain transaction fees below $0.01 on low-cost networks. For the Philippines, where overseas workers sent home a record $38.34 billion in remittances in 2024 (8.3% of GDP), even a modest reduction in fees represents billions of dollars staying in workers' families. See our research on stablecoin remittance corridors for a deeper analysis of specific corridors.

No Bank Relationship Required

A self-custodial wallet requires only a smartphone and an internet connection. There are no minimum balances, no monthly fees, no documentation requirements beyond what the wallet provider chooses to enforce, and no branch visits. Of the 1.3 billion unbanked adults, approximately 900 million own a mobile phone and 530 million have smartphones, suggesting a direct pathway from financial exclusion to participation through embedded wallet infrastructure.

Bypassing Correspondent Banking

Traditional cross-border payments route through chains of correspondent banks, each taking a cut and adding settlement delays. Bitcoin and stablecoin transfers settle directly between parties without intermediary banks. A Castle Island Ventures survey found that 39% of emerging market crypto users had used stablecoins for international remittances, and 23% had paid or received salary in stablecoins.

Why It Matters for Crypto

The unbanked represent both a massive underserved market and a proving ground for whether decentralized financial infrastructure can deliver on its promises. In Nigeria, where USDT accounts for 88.5% of stablecoin activity, 95% of surveyed users said they prefer receiving payments in stablecoins over naira. This is not speculative trading: it is people choosing more reliable money.

Spark's architecture is designed with these users in mind. Its self-custodial mobile wallet model requires no bank relationship, no minimum balance, and no complex onboarding. By supporting both Bitcoin and stablecoins on a Layer 2 network with minimal fees, Spark targets the exact pain points that keep 1.3 billion people out of the financial system.

Risks and Considerations

Infrastructure Gaps

Crypto solutions assume smartphone and internet access, but significant gaps remain. Over 300 million women in South Asia alone lack mobile phones. Rural connectivity is unreliable in many regions where the unbanked are concentrated. A wallet that requires constant internet connectivity does not fully solve the problem for offline-first populations.

Regulatory Uncertainty

The regulatory landscape for crypto-based financial services varies dramatically by jurisdiction. The U.S. GENIUS Act (enacted 2025) established the first comprehensive stablecoin framework, but most countries where the unbanked are concentrated have nascent or restrictive crypto regulation. Nigeria launched a crypto regulatory sandbox in 2025, signaling openness, but regulatory clarity remains uneven globally.

Volatility and User Education

While fiat-backed stablecoins mitigate price volatility, users must understand the difference between stablecoins and volatile assets like Bitcoin. Without adequate education, new users risk exposure to scams, phishing, and poorly designed protocols. The irreversibility of crypto transactions amplifies the consequences of user error.

On-Ramp and Off-Ramp Challenges

Converting between local currency and crypto (on-ramping and off-ramping) remains difficult in many unbanked regions. Without robust local exchange infrastructure or merchant acceptance, stablecoins risk becoming a closed ecosystem that cannot connect to the local economy. Peer-to-peer trading fills some of this gap (Nigeria saw $1.2 billion in P2P crypto trades in 2024), but liquidity and pricing can be inconsistent.

Unbanked vs. Underbanked

The distinction matters for solution design. The unbanked have no formal financial account at all. The underbanked have accounts but still rely on alternative services like payday loans or check cashing. In the U.S., the FDIC's 2023 survey found 4.2% of households are unbanked while 14.2% are underbanked. Globally, the World Bank defines unbanked as adults without an account at a financial institution or mobile money provider. Crypto solutions must address different needs for each group: CBDCs, stablecoins, and self-custodial wallets each serve different segments of the financially excluded.
