Who Supplies Microfinance? Formal, Semi-Formal, and Informal Providers Explained

When a poor woman in rural Bangladesh or sub-Saharan Africa needs a small loan to buy seeds or expand a roadside business, she rarely walks into a commercial bank. Most banks don’t want her as a customer – she has no credit history, no collateral, and often no formal identification. So where does she turn? The answer depends on what’s available in her community, and that’s exactly what the supply side of microfinance is about. Microfinance services – savings, small loans, insurance, and payment transfers for low-income households – are delivered through three distinct types of providers: informal, formal, and semiformal. Each plays a different role, reaches different clients, and comes with its own set of trade-offs.

Why the supply side of microfinance matters 🔗

Microfinance is often discussed from the demand side: who needs it, and why. But the supply side – who actually provides it – shapes whether poor people, especially women, can access financial services at all. According to the Asian Development Bank, microfinance supply comes from three categories: formal institutions like rural banks and cooperatives, semiformal institutions like NGOs, and informal sources like moneylenders and shopkeepers. Each category operates under different rules, targets different clients, and comes with different risks for borrowers.

Understanding who supplies microfinance isn’t just an academic exercise. It directly affects the cost of borrowing, who gets included, and whether financial services actually reduce poverty – or deepen debt.

Informal sources: the most accessible, and the most problematic 🔗

For most poor and low-income households in rural areas, microfinance services are supplied mainly by informal sources – family members, neighbors, local traders, and above all, moneylenders. These providers dominate simply because they are there when no one else is. They don’t require paperwork, credit scores, or collateral. A borrower can often get cash the same day she asks for it.

Moneylenders: fast cash, steep costs 🔗

Moneylenders are the most visible informal providers. They operate within communities, know their clients personally, and can disburse funds almost immediately. That personal knowledge is precisely what makes them willing to lend where banks won’t – they assess risk through reputation and social relationships rather than formal credit checks.

But that convenience comes at a price. Informal suppliers of credit charge higher interest rates than semiformal and formal sources, and because of their greater bargaining power and their clients’ limited alternatives, the terms they set may not allow borrowers to fully benefit economically. In many cases, borrowers find themselves in debt cycles where the interest alone outpaces any income gains. Moneylenders also tend to operate in localized areas, which limits their ability to move funds across communities or serve clients outside their immediate networks.

Community savings groups and ROSCAs 🔗

Not all informal microfinance is exploitative. Community-based savings groups – including Rotating Savings and Credit Associations (ROSCAs) – are a widespread and genuinely member-owned form of informal finance. Members pool regular contributions and take turns receiving the lump sum, making credit available without involving any outside lender. In some countries, informal schemes are an integral part of the culture and serve millions of people.

These groups work well for members with stable, predictable income. They break down when members face simultaneous shocks – like a drought or epidemic – that prevent everyone from contributing at once. They also lack the scale to serve large populations or offer diverse financial products beyond basic savings and credit.

Formal financial institutions: scope and structure, but limited reach 🔗

At the other end of the spectrum are formal financial institutions – commercial banks, state-owned development banks, rural banks, and credit cooperatives. These are regulated entities operating under government oversight, which gives them advantages informal providers can’t match: lower interest rates, deposit insurance, and a broader range of financial products including savings accounts, insurance, and payment services.

Banks entering the microfinance space 🔗

Historically, commercial banks avoided low-income clients. The transaction costs of small loans are high relative to returns, and poor borrowers lack the collateral banks traditionally require. That has been changing. Central banks and mainstream banks are now more intimately engaging in the financial inclusion agenda than ever before, partly through technology – mobile banking and digital payment systems reduce the cost of reaching remote clients significantly.

Some state-owned banks have been restructured specifically to serve rural and low-income populations. Indonesia’s Bank Rakyat Indonesia (BRI) is a well-known example: its unit desa system, reformed in 1983 to adopt market-oriented interest rates and profit-center accountability, became one of the most successful rural banking networks in the developing world.

Cooperatives and credit unions 🔗

Cooperatives and credit unions occupy a middle ground. They are member-owned like informal savings groups but operate under legal frameworks that give them more structure and accountability. They can take deposits, offer loans at regulated rates, and serve a defined membership base. Financial cooperatives, SACCOs, and credit unions exist in dozens of countries and are often the only regulated financial institution accessible in smaller towns and rural areas.

The main limitation of formal institutions – even cooperatives – is that their eligibility requirements, however modest, still exclude the very poorest. Women without land titles, formal employment, or any credit record often don’t qualify. Formal lenders offer lower costs and better protection, but their depth of outreach into the poorest populations remains limited.

NGOs and semiformal institutions: bridging the gap 🔗

The most significant innovation in microfinance supply came from a category that sits between informal lenders and formal banks: semiformal institutions, primarily non-governmental organizations (NGOs). Semiformal institutions – NGOs – use innovations like group lending to give insufficiently served people access to credit. They are typically not regulated by banking authorities, but they operate with organizational structure, external accountability, and a social mission.

How NGOs reach the poorest clients 🔗

NGOs entered the microfinance space precisely because formal banks wouldn’t. Their core innovation was replacing physical collateral with social collateral – using group dynamics, peer accountability, and community trust as the guarantee that loans would be repaid. The main attribute of the group-lending model of microcredit is the use of social rather than material collateral. Loans are made to small groups, and peer pressure ensures repayment.

This model was pioneered most famously by the Grameen Bank in Bangladesh, founded by Muhammad Yunus in 1983. Grameen organized borrowers – overwhelmingly women – into groups of five. Individual loans were disbursed, but group members were collectively responsible for repayment. Missed payments by one member prevented others from receiving their next loans, creating strong incentive for mutual support and accountability. The bank and Yunus were jointly awarded the Nobel Peace Prize in 2006 for this model of creating economic development from below.

Why women are the primary target 🔗

NGO-based microfinance programs have consistently focused on women – not purely for ideological reasons, but because evidence shows women are more reliable repayers and more likely to invest loan proceeds in household welfare, including children’s nutrition and education. Microcredit was a novel innovation at a time when women’s social networks were used as capital in the absence of their ability to pay the necessary collateral to acquire loans. Women’s existing community relationships – kinship networks, neighborhood ties, shared group membership – became the foundation of the lending model.

Women entrepreneurs account for only 4% of all conventional small business loans, which illustrates how comprehensively formal finance excludes them. NGOs moved in to fill that vacuum. Today, Grameen Bank’s total borrowers number nearly 10.56 million, and 97% of those are women.

The scale NGOs achieved 🔗

In Bangladesh alone, NGO-based MFIs grew from small pilots into institutions serving millions. A few NGOs have grown to become giant MFIs – including BRAC and ASA – with client bases ranging from 600,000 to over 2 million borrowers. ASA, for example, grew from 326,200 active borrowers in 1995 to over one million by 1999. BRAC is now recognized as the largest NGO in the world.

Beyond credit, NGO-run microfinance programs often bundle in financial literacy training, health education, and legal awareness – services that purely profit-driven lenders would never offer. Regular meetings associated with group-based lending models provide a forum for education and training, turning credit delivery into a platform for broader social development.

How the three tiers interact 🔗

Informal, formal, and semiformal providers don’t operate in complete isolation. In practice, poor households often draw on multiple sources simultaneously. A woman might save in an informal ROSCA, borrow from an NGO-run MFI for business investment, and gradually build a credit record that eventually lets her access a bank account. Specialized microfinance institutions continue to expand their services, collaborating and competing with banks, credit unions, mobile money, and other informal and formal member-owned institutions.

There is also a known phenomenon of informal intermediation – where MFI borrowers who receive loans on relatively better terms re-lend portions to even poorer neighbors who can’t qualify for formal or semiformal credit. This informal layering means the boundaries between tiers are often blurrier in practice than they appear in theory.

The CGAP typology of microfinance providers recognizes this complexity, classifying providers not just by whether they are formal or informal, but by whether they are regulated, whether they can take deposits, and what legal form they take – reflecting how diverse and layered the actual supply landscape is.

Strengths and limitations of each provider type 🔗

Informal providers win on accessibility and speed. They ask no questions a formal institution would require, and they’re present in the most remote areas. But they frequently charge exploitative rates, operate without any accountability mechanism, and can trap borrowers in debt rather than lift them out of it.

Formal providers offer regulated rates, deposit protection, and scale. Their weakness is exclusion: strict eligibility criteria mean the very poor – and especially women without property or formal employment – often can’t get in the door. Their transaction costs for small loans remain high without technological innovation.

Semiformal NGO providers have proven most effective at combining depth of outreach with some organizational accountability. The group lending model replaced collateral with social trust, making credit available to clients both informal lenders exploited and formal lenders ignored. Their main challenge is financial sustainability – without external donor funding or eventual self-sufficiency, even large MFIs struggle to maintain operations long-term.

The global microfinance market was estimated at US $156.7 billion in 2020 and projected to reach over $300 billion by 2026. Yet an estimated one billion women worldwide still lack access to even a basic savings account. The supply of microfinance has grown enormously – but it hasn’t grown evenly, and its depth into the poorest communities remains incomplete across all three provider types.

What do you think? Given that informal moneylenders remain the first point of financial contact for many poor women despite their high interest rates, what would it take to make semiformal and formal providers genuinely more accessible at the community level? And if social collateral – group accountability – is what made NGO microfinance work for women, what does that reveal about the assumptions built into traditional banking systems?
