Working brief
Why the missing middle is still missing, and where it might finally move
A working brief on small-business and early-stage finance in emerging markets. September 2026. Sources are linked in the text.
Every few years someone rediscovers the same fact: the small businesses that employ most people in Africa, Latin America, and South and Southeast Asia cannot borrow, and the startups that might grow into the next generation of employers cannot raise. The numbers have been large for so long that they have stopped being alarming. The formal financing gap for micro, small, and medium enterprises is now put at about $5.7 trillion, or $8 trillion once informal firms are counted, and roughly 70% of MSMEs in emerging markets say they lack adequate finance (IFC, October 2025; IFC). Measured against output, the gap is about 19% of GDP. SME loans amount to about 12% of GDP in high-income countries, 7% in middle-income countries, and 3% in low-income ones (Carvajal and Didier, World Bank, 2024). Roughly 30% of formal private firms across 109 economies are credit constrained, and constrained firms are the smaller ones (Islam and Rodriguez Meza, World Bank, 2023). In ten African countries the share is 53% (IFC, 2023).
I have spent the past year researching why no platform exists to facilitate this kind of lending at scale, and what could be done about it from a technology perspective. This note is my attempt to lay out the landscape as it stands today: what the gap is, why it has survived thirty years of programs designed to close it, who the players are and what each can and cannot do, the risks that never go away, and the handful of places where the economics might genuinely be changing. I am putting the research out in the open to hear from people who are also trying to solve these problems.
What "missing middle" means
The phrase describes firms that have outgrown microfinance but are too small, too informal, or too unusual for a bank. The Aspen Network of Development Entrepreneurs, which has done more than anyone to define the segment, calls them small and growing businesses: commercially viable, five to 250 employees, typically seeking growth capital between $20,000 and $2 million (ANDE). The Dutch Good Growth Fund, a fund of funds active in seventy countries since 2014, uses the same idea from the other side: SMEs that "have outgrown micro financing but do not yet have access to regular financial services" (DGGF). Deals between roughly $20,000 and $250,000 sit in the emptiest band: they are "too large for microfinance institutions' capacity" and "development finance institutions rarely go into this territory" (CSIS).
Two things about that definition matter for everything that follows. First, the missing middle includes both a shopkeeper who needs working capital and a software company that needs equity, and the finance those two need is different in kind, even though both are shut out for overlapping reasons. Second, the gap is defined by size, and size is exactly the dimension along which the machinery of development finance has the least reach.
Why it persists
There is no single villain. Five things stack on top of each other, and any serious attempt has to answer all five.
1. The cost of a credit decision is fixed. The loan is not.
Appraising, documenting, and monitoring a $30,000 loan takes roughly the same staff time as a $3 million one. UNCDF puts it plainly: "the costs to appraise and monitor investments for an SME are often the same as for larger transactions," which is why the segment sits "below the radar" of commercial banks, DFIs, and most impact investors alike (UNCDF, 2021). In microfinance the same arithmetic shows up as interest rates: operating expense is "the largest determinant of the rate the borrowers end up paying," and smaller loans need more operating cost per dollar lent (Rosenberg and others, CGAP, 2013).
The clearest measurement I have found is from East African agricultural SMEs. On loans between $15,000 and $1.75 million, commercial banks earn a net 3.2%, non-bank lenders lose 1.6%, and social lenders lose 15% before subsidies. Lenders name "high risks and origination costs as primary impediments" (Aceli Africa, 2024). The rational response of any lender is to write fewer, larger loans to the borrowers it already knows. That is what the margin allows.
2. The information a lender needs mostly does not exist
A bank in Lagos cannot look up most applicants. Credit-bureau coverage of adults in 2020 was 13.9% in Nigeria, 13.5% in the Philippines, and 36.4% in Kenya (World Bank Doing Business 2020, Nigeria, Philippines, Kenya). Without information, lenders ask for collateral, and in Sub-Saharan Africa the collateral demanded averages about 204% of the loan value; only 21.8% of firms there have a bank loan or line of credit, and firms fund three quarters of investment from their own cash (World Bank Enterprise Surveys). When a loan does go bad, a creditor in Sub-Saharan Africa recovers about 20.5 cents on the dollar, against 70.2 in high-income OECD countries (Doing Business 2020, regional profile). Underneath all of it is informality: 84% of workers in Africa are informal (ILO via WIEGO), which means the paper trail a credit model wants to read was never written.
3. Currency
A lender that raises dollars and lends naira is making a bet on the naira whether it wants to or not. From June 2023 to February 2024 the naira lost 69.5% of its value against the dollar (BusinessDay, 2024), and it lost another 40.9% during 2024 (BusinessDay, 2025). The Egyptian pound lost more than a third of its value on the day it was floated in March 2024 (AFP via Malay Mail). The Kenyan shilling fell 26.8% in 2023 (Cytonn). Moves of that size are the ordinary weather of these markets, and any structure that lends into them has to price for it.
The consequences land on the smallest balance sheets first. Watu, one of the largest asset financers in East Africa, saw its 2024 profits fall 85% on currency depreciation and impairments before recovering in 2025 (TechCabal, 2026). Lipa Later, a Kenyan buy-now-pay-later company that had raised $12 million of equity, entered administration in March 2025 with dollar debt on its books after the shilling had moved from about 100 to about 170 per dollar over the life of the business (TechCabal, 2025). The old CGAP guidance on microfinance FX risk still describes the trap precisely: hard-currency indexing "creates devaluation risk for the MFI's loan clients, except in those rare cases where clients' income is denominated in hard currency," and hedges are often "unavailable or problematic because of the small size of the transactions" (CGAP, 2006). Economists have a name for the underlying condition: original sin, the inability of most countries to borrow abroad in their own currency, which Eichengreen, Hausmann, and Panizza traced to the structure of global portfolios rather than to any single country's policy (NBER, 2003). Only two African sovereigns, Botswana and Mauritius, carry an investment-grade rating (Cleary Gottlieb, 2023), which sets a ceiling on how cheaply anyone inside those borders can borrow, whatever their own record.
4. Well-meant policy has a habit of making it worse
Kenya capped lending rates at four points above the policy rate in September 2016. The number of loan accounts fell 26.1% within nine months while the average loan size rose 36.7%, which the central bank read as "lower access to small borrowers," and it estimates that rationing MSMEs out of credit cut 2017 growth by 0.4 percentage points (Central Bank of Kenya, 2018; IMF, 2019). Andhra Pradesh's 2010 ordinance against microfinance collections pushed repayment from 99% to under 20% in weeks (CGAP, 2010). China's peer-to-peer lending sector went from roughly 6,000 platforms at its peak to zero by late 2020, leaving more than 800 billion yuan unpaid (Reuters via Yahoo, 2020; China Daily). And Kenya's own digital-credit boom, the most celebrated fintech story on the continent, ended its first act with 27% of adults having borrowed, about half of them late at least once, and 13% in default (CGAP, 2018), followed by a licensing regime that has admitted 252 providers out of more than 800 applicants (Central Bank of Kenya, July 2026). Regulation is necessary in all of these markets; the segment is simply fragile to rules written for someone else.
5. On the equity side, there is nowhere to exit
Venture capital in these markets is small and, more importantly, hard to get out of. Africa attracted $4.1 billion of tech funding in 2025, and $1.64 billion of that, 41%, was debt (Partech, 2026). In 2024 the continent's share of global venture funding fell below 1%, the median VC deal was $2.5 million, and there were 26 VC-backed exits all year (AVCA, 2025). Latin America saw $4.5 billion across 751 deals, with sixty companies that have each raised more than $150 million still waiting to list or be acquired (LAVCA, 2025). Southeast Asia's activity has reset to 2016 levels (Cento Ventures, 2025). Across emerging markets as a whole, private equity and venture funds returned a pooled net 8.47% a year over ten years, about 400 basis points below global public equities (Cambridge Associates, 2026). A limited partner reading those numbers does not need a lecture on political risk to decide where the marginal dollar goes.
The accelerators and studios that sit at the front of this pipeline help, but less than their brochures suggest. The Global Accelerator Learning Initiative, which compares accepted ventures with rejected ones, finds that accelerated ventures in emerging markets gained about $15,000 more revenue and $14,000 more equity over a year than their rejected peers, that accepted ventures start out well ahead of rejected ones, and that "for many individual accelerator programs, accepted ventures do not end up outperforming rejected ventures" (GALI, 2017; GALI, 2021). Venture studios look better on follow-on funding, with about half of studio-built African companies raising a next round against roughly a third for accelerator alumni, on a base of forty-odd studios and 160 companies (GIZ SAIS, 2026). Useful, and small.
The players, and what each can actually do
Development finance institutions
The DFIs and multilateral banks hold the largest pools of patient capital aimed at these markets, and they are structurally unable to make small loans. That is by design. IFC states outright that it "does not lend directly to micro, small, and medium enterprises or individual entrepreneurs" (IFC). Every investment passes through a twelve-stage project cycle with Board approval (IFC), an environmental and social categorisation (IFC), and the eight Performance Standards that apply "throughout the life of an investment" (IFC, 2012). At the U.S. DFC, the process runs "a minimum of six to nine months" from formal application to commitment, with background checks and site visits (DFC). The European Investment Bank's direct loans start at €25 million (EIB).
The ticket sizes follow. Between 2012 and 2016 the median commitment was $7.6 million at FMO, $12.6 million at OPIC, $22.8 million at CDC and $25 million at IFC, and only 15% of IFC commitments were under $1 million (Kenny and others, CGD, 2018). The World Bank's own evaluators found in 2014 that direct investments in SMEs made up one percent of IFC commitments and that many targeted SME projects were "weakly justified, weakly focused on SMEs, and/or have limited potential for additionality" (IEG, 2014). Low-income countries received 6.4% of DFI and MDB commitments in 2018; 72% went to countries within six rating notches of investment grade (Attridge and Gouett, ODI, 2021).
So DFIs reach small firms through intermediaries: they lend to and guarantee local banks and microfinance institutions, which lend onward. The scale of that channel is real. IFC's client financial institutions held $285 billion of SME loans across 5.4 million loans in 2023 (IFC Annual Report 2024). The DFC's portfolio guarantees can cover up to 80% of a bank's losses, and its own worked example describes a $50 million "micro" portfolio of 20,000 borrowers averaging $2,500 each, because those are borrowers "it would be impossible for DFC to underwrite individually" (DFC; DFC). FMO's NASIRA program, backed by EU guarantees of up to €365 million, shares losses with more than forty banks on loans to young, female, and migrant entrepreneurs (European Commission). Proparco's new Impact+ facility will issue guarantees of €2 million to €50 million to banks and MFIs covering loans as small as €500, up to 80% (Proparco, 2025).
The intermediated channel also has a long record of leaking. An evaluation of $13.4 billion of World Bank lines of credit found outcomes satisfactory in 45% of commitments by value, cancellations above 40%, fewer than half the projects using clear eligibility criteria for intermediaries, and almost 40% with no information on repayment rates (IEG, 2006). IFC, per its evaluators, "typically neither demanded nor received any information from financial intermediaries about their clients," and for wholesale guarantees there was "no evidence that the long-term tenor was passed on to end-borrowers" (IEG, 2014). Blended finance, the hoped-for multiplier, mobilises about $0.75 of private money per public dollar overall and $0.37 in low-income countries (Attridge and Engen, ODI, 2019). The market did $18 billion in 2024 with a median deal of $65 million; SME-focused deals in Sub-Saharan Africa were 27% of the count but 14% of the money, and only 18% of them were under $5 million (Convergence, 2025; Convergence, 2024). Even IDA's Private Sector Window, purpose-built for the hardest markets, had used only 53% of its first allocation and paid out about $1 million in six years against $1.2 billion set aside (IEG).
A DFI dollar reaches a $5,000 borrower only through two or three layers of institutions, each of which needs its own reason to bother, and the plumbing between the layers is where the money slows down.
Guarantors
Partial credit guarantees are the instrument closest to the problem, and the one with the strangest record. Public schemes are supposed to cover at least 50% of a loan and to be evaluated on additionality, which the World Bank's own principles admit is "technically challenging because of the difficulties in establishing a counterfactual" (World Bank, 2015). The evidence that they change bank behaviour is "mixed": Colombia's Fondo Nacional de Garantías did increase SME lending, while Malaysian participants' default rates rose and German schemes were associated with more risk-taking (Abraham and Schmukler, World Bank, 2017). Across Central and South-Eastern Europe, schemes ran net loss ratios averaging 3%, which the reviewers suspected "may also reflect the fact that guarantees are not reaching the smaller SMEs" (Vienna Initiative, 2014). In OECD countries, guaranteed loans are about 8% of the SME loan stock (OECD, 2024).
The recurring complaint from lenders is operational. A survey of nineteen Latin American schemes found that "the more complex the procedures for claiming the guarantees, the less the interest from participating financial institutions," that ten schemes required proof of legal notification before paying, and that the schemes' own most pressing difficulty was streamlining documentation and building IT to automate procedures (World Bank, 2022). Elsewhere, "banks often complain that PCG administrators require them to file cases in courts and carry out time-consuming verification of claims," with a median of 120 days from missed payment to trigger (World Bank). Sri Lanka's scheme saw so many claims rejected for late or incomplete paperwork that lenders "shied away" (ADB, 2022). The IDB Group, over fifteen years, did fewer than 4% of its lending as guarantees.
Where the paperwork has been engineered away, guarantees scale. India's CGTMSE runs entirely through a portal with an API that lets a bank branch initiate a guarantee, and settles 75% of claims on first submission (SBI, 2025). Colombia's FNG guaranteed 953,787 credits in 2025 through a portal the lender uses and the borrower never sees (El Tiempo, 2026; MinHacienda). The African Guarantee Fund has issued $2.75 billion of guarantees to 256 partner lenders in 44 countries (AGF). Nigeria's InfraCredit has about ₦310 billion of guarantees outstanding with zero calls across 26 guaranteed entities (InfraCredit). And the newest program is the largest: the World Bank's FINCLUDE project, approved in December 2025, routes $500 million through Nigeria's Development Bank to issue up to $800 million of partial guarantees to banks, microfinance banks, and fintech lenders for 250,000 MSMEs, with an "AI-enabled digital platform for loan appraisal" written into the design (World Bank, 2025). The Philippines' PhilGuarantee has issued ₱252 billion of guarantees cumulatively, though housing dominates and MSME programs account for ₱7.46 billion (PhilGuarantee, 2024). Guarantee capacity, in other words, is being created faster than the capacity to originate loans that qualify for it.
The currency specialists
The most important institution most people have never heard of is TCX, The Currency Exchange Fund, set up in 2007 by a group of DFIs to sell the hedges that commercial banks will not. It hedged a record $2.84 billion in 2025 across 54 currencies and 572 transactions, has enabled almost $20 billion of local-currency lending since it started, writes fixed-rate hedges out to 25 years, and describes itself as "often the only option in frontier currencies" (TCX, 2026; TCX). Its shareholders are KfW, EBRD, FMO, EIB, IFC, and AFD among others, and its rating agency notes "very high exposure to market risk relating to frontier currencies," with three currencies driving more than half of its losses in each of its bad years (S&P via TCX, 2025). The microfinance and SME sectors are its main beneficiaries (TCX Annual Report 2025). MFX Solutions, created in 2009 for smaller microfinance lenders and backed by DFC guarantees, has hedged around $5 billion in more than 55 currencies, laying the risk off to TCX or banks (MFX). IDA's Local Currency Facility backstops IFC lending "in markets in which currency hedging options are absent or very limited" (IDA), and IFC has written more than $30 billion of local-currency debt in 67 currencies over a decade (IFC, 2025).
Two limits define this corner. First, price. TCX's own analysis notes that "in many frontier currencies, there is no established price for the risk" and that the exchange-rate-adjusted yield on dollar debt for high-risk countries has exceeded 15% (TCX, 2026). For the naira, TCX offers fixed-rate hedges only; for the peso, shilling and Philippine peso it offers both fixed and floating (TCX). Second, size. The Mexican peso trades $147 billion a day in the global FX market; the naira and shilling are not even reported separately (BIS, 2025). The commercial market will price a $10 million naira forward; nobody prices a $10,000 one. Hedging is a portfolio activity, and whoever wants it has to bring a portfolio.
Venture investors, studios, and accelerators
DFIs do reach startups, as limited partners rather than direct investors. IFC has committed about $3 billion to more than 120 venture funds, seed funds, and accelerators (IFC); DFC's recent fund commitments run from $13 million to $40 million per fund (DFC, 2024). Antler's East Africa fund was $13.5 million, writing checks up to $100,000 (TechCrunch, 2022); Flat6Labs manages about $95 million across eight vehicles with tickets from $50,000 to $500,000 (Flat6Labs, 2023); Village Capital's alumni have raised about $1 billion on $17 million of direct investment (Village Capital). Y Combinator took 24 African startups in its winter 2022 batch and three in winter 2024 (WeeTracker, 2024). This layer selects well and signals well. It does not move the missing middle, because most of the missing middle is not venture-shaped: a viable trucking company or rice processor needs debt with a repayment schedule, and the venture industry, correctly, does not lend.
The non-bank innovators
This is where the interesting things are happening, and each one is worth describing by mechanism rather than by brand.
Reverse factoring anchors the credit on the buyer, not the small supplier. Mexico's NAFIN pioneered it at scale: by 2004 its Cadenas Productivas platform had 190 large buyers, more than 70,000 SME suppliers, about twenty lenders, and eleven million transactions, without recourse to the supplier and priced well below commercial rates (Klapper, World Bank, 2006). Its volumes later fell 40% in real terms as private banks copied the model (IPD Columbia), which is what success looks like for a development bank. India's TReDS exchanges, on which only MSMEs may sell invoices and buyers above ₹250 crore of turnover must register, have crossed ₹2 lakh crore of cumulative financing on RXIL alone (IBEF, 2025; RBI). In Mexico, Xepelin, Konfío, and Mundi now underwrite from the government's electronic invoice data and fund themselves with Goldman Sachs and Column facilities, in Konfío's case with a proposed 80% DFC guarantee on a $340 million line (DFC; Bloomberg Línea, 2022).
Asset financing ties repayment to a productive thing the lender can see. M-KOPA has extended more than $2 billion of credit to seven million customers for phones and solar, with default rates it has described as "a little above 10%" (M-KOPA, 2025; TechCrunch, 2023). Untapped Global finances motorbikes, water pumps, and similar assets that report their own usage and repays investors from a share of each asset's revenue, across 55,000 assets (Untapped Global).
Private credit funds and venture debt aggregate the small tickets that DFIs cannot touch. Lendable had invested $576 million in eighteen countries with a 13.15% net IRR and 2.3% principal write-offs by the end of 2024, and 60% of its capital sits in subordinated tranches that make the senior layer safe enough for institutions (IFC; Convergence, 2026). Partech notes that most of Africa's record $1.64 billion of venture debt in 2025 was "labelled in USD with high interest rates" (Partech, 2026), which sends us back to the currency section.
Retail and crowd platforms prove the demand exists and show its ceiling. Kiva has moved $2.4 billion through 2.9 million loans with a 96.4% repayment rate, and its lenders earn nothing (Kiva; Kiva). Lendahand, licensed under the EU's crowdfunding regulation, has placed €232 million since 2013 from about 20,000 investors at 2% to 8% interest, with write-offs of 0.37% on loans to financial institutions and about 5% on direct loans to companies (Lendahand; Lendahand). Colombia's A2censo bolts a 50% to 70% FNG guarantee onto crowd-funded SME debt and had five defaults in its first hundred campaigns (Valora Analitik, 2023). The ceilings are regulatory and arithmetic: the EU regime caps offers at €5 million per issuer per year (EU Regulation 2020/1503), U.S. Regulation Crowdfunding is closed to issuers not organised in the United States (17 CFR 227.100), and global equity crowdfunding was about $2.2 billion in 2020 against venture capital in the hundreds of billions (CCAF).
The underwriting innovators
The oldest promise in fintech is that data can substitute for collateral. The evidence is now good enough to say when that is true.
Tala, founded in 2011, underwrites from the data on a borrower's phone and has lent nearly $6 billion to ten million people in Kenya, the Philippines, Mexico, and India, reporting 90% repayment on its flagship product (Tala, 2024). Kenya's M-Shwari cut its 90-day non-performing rate from 6.1% to 2.2% by adding a second scorecard built on the borrower's own behaviour inside the product (CGAP and FSD Kenya, 2015). JUMO has disbursed more than $10 billion in nine African markets (GlobeNewswire, 2026). Psychometric scoring, once a curiosity, has controlled trials behind it: in Peru, bank-approved borrowers whom the psychometric score would have rejected were 8.6 percentage points more likely to fall 90 days behind (Arráiz, Bruhn, and Stucchi, World Bank, 2017), and an Ethiopian pilot with uncollateralised loans kept portfolio at risk under 2% (World Bank, 2019). Pula insures more than 21 million smallholders using satellite and weather data, which is underwriting by another name (Pula).
The newest layer reads the documents themselves. Kita, a 2025 startup in Y Combinator's winter 2026 batch, uses vision-language models to turn bank statements, invoices, and payslips into "fraud-checked, decision-ready signals," raised a $4.5 million seed led by BoxGroup with Tala's founder among the angels, and reports $130 million of loan volume processed for lenders in the Philippines, Indonesia, Mexico, and the United States in its first five months (Y Combinator; Menlo Times, 2026). In Nigeria, Indicina sells statement analysis and decisioning to about 120 lenders (TechCabal, 2022) and Lendsqr sells the loan-management rails, and its founder has said the quiet part: "Technology alone cannot scale a loan business without adequate capital" (TechCabal, 2024).
The academic literature is careful in a way that vendors are not. Machine-learning models using non-traditional data predict defaults better than bureau scores, and the advantage is largest "in the presence of a negative shock" and smallest for borrowers with long credit histories (BIS, 2019); big-tech credit reacts to transaction flows rather than to collateral values and could "reduce the importance of collateral" (BIS, 2020). The IMF warns that these models fail when "a deep structural change occurs" or when borrowers learn to counterfeit the indicators (Bazarbash, IMF, 2019), and the fairness literature finds that machine-learning underwriting widened rate dispersion across groups by 23% in U.S. mortgages (Fuster and others). CGAP reports that 65% of financial providers do not monitor their AI for discrimination (CGAP, 2026). The open-finance rails that would feed these models are uneven: the Philippines launched a central-bank pilot in 2023 (IFC, 2023), Mexico's rules cover open data but not transactions (LatamFintech), and Nigeria's open banking had not gone live as of late 2025 (TechCabal, 2025).
The risks that do not go away
Anyone proposing to lend small in these markets should be able to recite the losses.
Default. Kenya's banks ended 2024 with a gross non-performing ratio of 17.1%; on MSME loans specifically, 19.1% of value and 28.4% of accounts were non-performing, and banks wrote off 95,179 MSME loans that year. The same report shows why banks stay in the segment anyway: MSME lending was 21.4% of loans but 35.3% of lending income (Central Bank of Kenya, 2025). Nigeria's system-wide ratio rose to 8.1% in 2025 and Ghana's stood at 21.8% (World Bank WDI). Global microfinance portfolio at risk over 30 days sat around 7% before the pandemic (Microfinance Barometer, 2019). Kenya's government-run Hustler Fund reported defaults of 78% before recovery efforts brought them to 15%, and its auditor found 386,735 defaulter accounts closed without supporting evidence (The Star, 2026; Nation, 2026).
Fraud. Across 110 million identity checks in Africa in 2024, one provider recorded an overall fraud rate of 25%, biometric fraud averaging 16% a quarter, and microfinance institutions and digital banks as the most targeted lenders (Smile ID, 2025). Nigeria's interbank settlement system logged ₦17.67 billion of payment fraud losses in 2023 across 95,620 incidents (NIBSS via Vanguard, 2024). Loan stacking is structural: in Kenya's first digital-credit wave, 14% of borrowers held loans from multiple providers at once (CGAP, 2018). Document fraud is precisely the thing the new document-intelligence tools exist to catch, which tells you how common it is.
Concentration. Supply-chain finance concentrates on the anchor by design, and Greensill showed what happens when nobody watches that concentration: Credit Suisse froze $10 billion of Greensill-backed funds in 2021, and the U.K.'s auditors found Greensill had made six loans worth £240 million to parts of one group on a single day under a scheme with a £50 million per-borrower cap (The Guardian, 2025; The Guardian reporting the NAO, 2021).
Currency and politics. The devaluations above are the ordinary case. For the extraordinary ones, MIGA insures against expropriation, currency inconvertibility, war, and breach of contract, issued a record $9.5 billion of guarantees in fiscal 2025, and has paid twelve claims in its history (MIGA; World Bank, 2025).
Model drift and regulatory whiplash. Every scoring model above was trained on a particular macro regime, and the IMF's warning about structural change is a warning about exactly the devaluations and rate caps this note began with.
How other industries solved the same problem
Here is the part I find genuinely encouraging. The problem of letting thousands of small originators safely draw on large pools of capital is not unsolved. It has been solved, repeatedly, in other industries, and the solutions share a shape.
The U.S. Small Business Administration's 7(a) program guarantees 85% of loans under $150,000 and 75% above, and its Preferred Lender Program gives approved lenders "delegated authority to process, close, service, and liquidate" loans without prior SBA review. About 80% of 7(a) approvals now come through delegated lenders; the program did 77,600 loans for $37 billion in fiscal 2025, with charge-offs around half a percent (SBA; SBA, 2026; SBA, 2025). The mechanism is a rulebook, the Standard Operating Procedure, that defines an eligible loan precisely enough that the government can trust a stranger to make it.
The U.S. mortgage market does the same at a scale that is hard to picture. Fannie Mae's Selling Guide defines what a conforming loan is; about 1,200 lenders delivered loans to Fannie Mae in 2025, the top five accounting for only 36%, and non-bank originators now write 85% of agency mortgages against $9.3 trillion of agency securities outstanding (Fannie Mae 10-K, 2026; Urban Institute, 2026). Europe wrote a version of this into law with the 2019 "simple, transparent and standardised" securitisation label, which now covers 41.8% of new issuance (AFME, 2026), and the European Investment Fund deploys close to €35 billion of InvestEU guarantees through more than 300 partner institutions (EIF; EIF, 2026).
Trade finance has run on shared rules for longer than any of them. The ICC's UCP 600 has governed letters of credit since 2007 and URDG 758 has governed demand guarantees since 2010; on 32 million transactions worth $16 trillion, the ICC Trade Register measured default rates of 0.04% on export letters of credit and 0.36% on import ones (ICC). Because the documents are standard, IFC's Global Trade Finance Program can guarantee local banks it has never underwritten in detail, and has supported more than $141 billion of trade over two decades (IFC).
Microfinance built its own version. Microfinance investment vehicles such as Symbiotics and BlueOrchard pool hundreds of small institutions for institutional money; Symbiotics alone has made more than 9,400 investments totalling over $12 billion in 669 institutions across 99 countries (Symbiotics), and private impact funds now hold $103.7 billion (Tameo, 2025). What made a Cambodian MFI investable from Geneva was a reporting standard (MIX Market, founded 2002) and a certification (the Smart Campaign's client-protection standards, now run by Cerise+SPTF) that reduced the diligence a buyer had to do from scratch (Cerise+SPTF). Insurance has done it since the eighteenth century: Lloyd's writes £55.5 billion of premium through more than a hundred syndicates and 3,000 coverholders who bind risk on the market's behalf under its rules (Lloyd's, 2025). Warehouse receipt laws in Kenya, Uganda, and Tanzania turned stored grain into collateral a bank will accept (WRSC Kenya). Visa's core rules let about 14,500 financial institutions interoperate on 329 billion transactions a year (Visa); India's account-aggregator framework has processed 538 million data-sharing consents (Sahamati). The American fintech lenders that could not get bank charters solved it with partnership: Upstart originates through more than a hundred lending partners with 91% of loans fully automated (Upstart 10-K, 2026), though the legal fights over who the "true lender" is have never fully ended.
Development finance has pieces of this stack but not the stack. The World Bank published sixteen principles for credit guarantee schemes in 2015 (World Bank); the Operating Principles for Impact Management have 183 signatories (Impact Principles); IRIS+ has 781 metrics (GIIN); the 2X Challenge has moved $33.6 billion under a shared gender-lens definition (2X Global). CGTMSE and FNG have the portals. NASIRA and the DFC's pooled guarantees have the risk-sharing. GTFP has the standard documents. What none of them has, for a $5,000 to $100,000 business loan in Lagos or Cebu, is the combination those other industries take for granted: a written definition of an eligible loan, delegated authority to originate against it with audit rather than pre-approval, a shared backstop that sits behind many small originators, reporting rails that make the portfolio legible without a site visit, and a certification that lets a twelve-person lender be trusted by a $100 billion balance sheet. Each industry above built that combination once, usually after a crisis, and then grew for decades on it.
Where the economics might actually be moving
I want to be careful here, because this is where most writing about emerging-market finance stops being honest. The deep constraints, informality, thin markets, weak enforcement, currency, will not be automated away. What can change is the cost of the steps that turn a willing borrower into a loan a guarantor will stand behind and a lender will book. Five of those steps look different than they did five years ago.
The credit decision is getting cheap for the first time. Document reading, statement analysis, and alternative-data scoring have moved from research to production, and the evidence above says they work best exactly where bureau data is thin. If the fixed cost of a decision falls from a credit officer's afternoon to a few cents of compute plus a review, the arithmetic in the Aceli report changes and the loan size at which a lender breaks even falls with it. That is the single most important shift, and it is already visible in Tala's and M-Shwari's loss rates and in the speed at which a three-person company like Kita has reached lenders on three continents. It is also incomplete, as Lendsqr's founder said, because a cheaper decision does nothing without capital behind it.
Guarantee eligibility can be checked before the loan is made, and claimed without a lawsuit. Every failure mode in the guarantee literature is a paperwork failure: eligibility unclear, reporting late, claims rejected for missing evidence, court filings required before payout. CGTMSE's portal and FNG's show that when the guarantor exposes its rules as software, uptake follows. FINCLUDE's $800 million of new Nigerian guarantees will reach 250,000 businesses only if the long tail of microfinance banks and fintech lenders can originate qualifying loans and report on them, and that is a software problem sitting on top of a policy achievement.
Short tenors and anchored receivables make currency risk a portfolio product rather than a personal bet. Nobody will hedge one $8,000 naira loan, but TCX and MFX will hedge a portfolio, and a 60-day receivable against a creditworthy processor is a very different exposure from an 18-month term loan to its supplier. Reverse factoring puts the credit on the party that can bear it, and it comes with a scale precedent (NAFIN, TReDS) and a cautionary tale (Greensill) that together describe the design constraints: anchor limits, invoice verification, no recourse to the small supplier, and someone watching the concentration.
Pooling to the thresholds that DFIs can actually fund. The DFC's own model of a $50 million portfolio of 20,000 borrowers at $2,500 each, Proparco's guarantees covering loans from €500, Lendable's subordinated structure, A2censo's guaranteed campaigns: these are all the same idea. A DFI will never appraise the borrower, but it will appraise the pool if the pool is built to a standard it recognises. The originator's job is to build the pool to that standard from the first loan, and to make the reporting so legible that the layers of intermediaries stop leaking.
The diaspora is a capital source that already prices the currency risk correctly. Remittances to low- and middle-income countries reached $685 billion in 2024, more than foreign direct investment and aid combined; Mexico received $68 billion and the Philippines $40 billion, and Nigeria received about $19.5 billion the year before (World Bank, 2024; World Bank/KNOMAD, 2024). Someone who sends money home already holds naira or peso obligations and reads a Lagos business more accurately than a fund manager in Geneva. The record of diaspora bonds is mixed, from Nigeria's oversubscribed $300 million in 2017 to Kenya's 24% of target on M-Akiba (Vanguard, 2017; Diaspora for Development), which suggests the product has to be closer to the businesses than a sovereign bond and more structured than a family loan.
None of these five is a business on its own, and none is new as an idea. What is new is that the first one, the cost of the decision, has moved enough that the other four might finally be worth assembling around it. That is the hypothesis I am spending this year testing, in conversations with lenders, guarantors, founders, and the people who send money home. I am not claiming to have the design. I am claiming that the shape of the design is legible now in a way it was not, that the pieces exist in other industries and in fragments in this one, and that the honest work is in the plumbing.
