Inside FMBN: anatomy of the largest formal diaspora mortgage programme

I. The product on the screen

The Federal Mortgage Bank of Nigeria publishes, on a portal accessible from anywhere in the world, an application form for what it calls the Diaspora National Housing Fund Mortgage. The product is intended for Nigerians living outside the country. The terms are explicit. The interest rate is nine per cent per annum, fixed. The application fee is fifty US dollars, non-refundable. The borrower must contribute to the National Housing Fund for at least twelve months before becoming eligible. Eligible properties are located in Lagos, Abuja, Port Harcourt, and Kano. The bank reserves the right to dispose of the property without further recourse if loan repayments are in default for three months.[^1]

These terms describe what is, on any reasonable measure, the most ambitious formal diaspora mortgage programme operated by any country in the world.

The Federal Mortgage Bank itself was created in 1956 and reconstituted by an Act of Parliament in 1993, with the mandate of serving as the apex mortgage institution in Nigeria. It administers the National Housing Fund, a contributory savings scheme established by the National Housing Fund Act of 1992. The fund mobilises long-term capital from Nigerian workers, banks, and insurance companies, and lends it back to eligible borrowers at concessionary rates.[^2] In a country whose commercial mortgage market quotes rates between twenty and twenty-eight per cent — and whose central bank policy rate sits at twenty-seven — the FMBN's single-digit pricing represents a discount of roughly seventy per cent below the prevailing alternative.[^3]

The product exists. It functions. It has been operating, in its current form, for more than a decade. And yet, examined in detail, it tells a more complicated story than its headline numbers suggest. The structure that makes it possible is the structure that constrains its scale. The mechanism that delivers nine per cent to a small number of Nigerians is the same mechanism that ensures it cannot deliver nine per cent to most of them.

What follows is an examination of how FMBN works, what it has delivered, where its limits lie, and what its experience implies for the wider project of bringing diaspora communities into the formal credit system.

II. The Act of 1992

The National Housing Fund Act, signed into law on 31 January 1992, did three things.[^4] It established a national pool of long-term capital for housing finance. It set the mechanism by which that pool would be funded. And it created a regulatory architecture under which the Federal Mortgage Bank would administer the pool on behalf of contributors.

The funding mechanism was the innovation. Under section 4 of the Act, every Nigerian earning more than three thousand naira per annum — a threshold which, at the time of enactment, captured nearly all formally employed workers — was required to contribute 2.5 per cent of their monthly basic salary to the fund. The deduction was made at source by the employer and remitted to FMBN. Commercial and merchant banks were required to invest 10 per cent of their loans and advances portfolio in the fund. Insurance companies were required to invest 20 per cent of non-life funds and 40 per cent of life funds in the housing sector, with half of that directed into NHF.[^5]

The mechanism solved the structural problem that has defeated every other African housing-finance system: the absence of long-duration capital. Commercial banks in Nigeria, as in most low-income economies, fund themselves predominantly through short-term customer deposits. They cannot prudently match a thirty-year mortgage against deposits with average duration under twelve months. The NHF, by drawing on payroll deductions, bank loan-book allocations, and insurance reserves, created a capital pool whose duration matched the lending product. This is the same trick Singapore performed with the Central Provident Fund and the Housing Development Board — a scheme that has produced the world's highest formal-sector home-ownership rate, currently around eighty-nine per cent.[^6]

The 1992 Act, however, was constructed against a particular political and demographic context that has since changed. The mandatory contribution applied to all formally employed Nigerians. In 2020, the Banks and Other Financial Institutions Act amended section 4 of the NHF Act, making contributions voluntary for private-sector employees.[^7] The change reduced the funding base materially. Public-sector contributions continued, but the private-sector base — which by then represented a growing share of formal employment — became optional, and most private employers ceased remitting.

The consequence is visible in the disbursement data. Between May 2023 and early 2025, FMBN disbursed N11.75 billion in NHF mortgage loans to 1,285 beneficiaries.[^8] These are real loans. They are also small in number. By comparison, Nigeria's annual housing-unit demand is estimated at between seven hundred thousand and one million units. FMBN's two-year output represents a fraction of one per cent of that demand.

The Act of 1992 worked. The Act of 1992, in its current diminished form, cannot scale.

III. What the product actually delivers

The arithmetic of FMBN's NHF programme, viewed across its full range, reveals what a subsidised diaspora-eligible mortgage system can deliver and what it cannot.

Between May 2023 and early 2025, the bank's reported disbursements broke down as follows.[^9] Direct NHF mortgage loans: N11.75 billion across 1,285 beneficiaries, implying an average loan size of approximately N9.1 million — equivalent, at prevailing exchange rates, to roughly six thousand US dollars. The Rent-to-Own programme, which allows Nigerians to move into FMBN-financed properties and pay toward eventual ownership through monthly rentals, disbursed N15.06 billion to 1,140 beneficiaries. The Home Renovation Loan facility, which finances upgrades to existing properties, disbursed N15.35 billion to 27,900 beneficiaries. Estate Development Loans financed the construction of 2,542 new housing units at a total cost of N30.91 billion.

These numbers are simultaneously impressive and modest. They demonstrate that a sovereign-backed mortgage product, priced at single digits in a high-rate environment, generates real demand and real take-up. The Home Renovation programme in particular — reaching nearly thirty thousand beneficiaries in two years — shows that when the price is right, the volume is there. They also demonstrate, however, that the supply is structurally constrained. NHF collections in 2025 reached N152.4 billion, a 48 per cent year-on-year increase that the bank attributes to digital-transformation initiatives.[^10] N152 billion, at current exchange rates, is approximately one hundred million US dollars. This is the annual fuel available to finance a country with a population of two hundred and twenty million and a housing deficit estimated by the Federal Ministry of Housing and Urban Development at between seventeen and twenty million units.[^11] The arithmetic does not close. The annual funding base, deployed in full, would finance under one per cent of the annual demand.

The bank has acknowledged this gap and has spent the last twenty-four months focused on three operational levers. The first is recovery of non-performing loans. Seven Loan Recovery Task Teams established across Nigeria's six geopolitical zones and the Federal Capital Territory have recovered N18.9 billion of delinquent loans over the past year, freeing that capital for redeployment.[^12] The second is digitalisation. A new Core Banking Application went live in April 2025, enabling online registration, contribution tracking, loan application, and status monitoring.[^13] The third is the launch of two new products: a Rental Assistance Loan and the formal expansion of the Diaspora NHF Mortgage in partnership with the Nigerians in Diaspora Commission.

The Diaspora product, in particular, is positioned as a response to Nigeria's annual remittance inflows of more than twenty billion US dollars.[^14] FMBN's own messaging frames it as a mechanism to channel a portion of those flows into the housing sector, providing both housing capital and foreign-exchange inflows. The bank states that the product will allow Nigerians abroad to participate in the NHF Scheme, make monthly contributions, and access mortgage financing without travelling to Nigeria. The instruments to do this exist. The institutional capacity to do it at scale, given the current funding constraints, does not.

IV. The diaspora dimension, examined

The diaspora-specific terms warrant closer examination, because they reveal what a formal diaspora mortgage system actually looks like when constructed under conventional sovereign-backed financial architecture.

Under the published terms, a Nigerian living abroad must first register with the NHF Scheme through FMBN, make monthly contributions for a minimum of twelve months, and only then become eligible to apply for a loan.[^15] The twelve-month contribution requirement is double the six months applied to domestic NHF participants. The reason, presumably, is verification: FMBN needs to establish a contribution history before extending credit, and for diaspora applicants the absence of an employment relationship within Nigeria makes alternative verification more difficult. The interest rate is nine per cent rather than the six per cent typically offered to domestic NHF beneficiaries. The geographic eligibility is restricted to four major capital cities. The application fee is denominated in US dollars rather than naira.

Each of these adjustments is rational from the standpoint of FMBN's risk management. Each of them also limits the universe of borrowers and limits the universe of properties that can be financed. A Nigerian doctor in Manchester who wishes to build a house in her ancestral village in Ekiti State cannot use the product. She can, on paper, finance a flat in Lagos, but she cannot finance the house her mother wishes to live in. The product is structured around what the bank can underwrite, not around what the diaspora wants to build.

The diaspora's actual building behaviour can be inferred from independent surveys. IFAD and OECD research indicates that more than forty per cent of remittance flows globally are deployed into real estate, family businesses, or informal lending to relatives, often in geographies that fall outside the eligibility perimeter of any formal mortgage product.[^16] A meaningful proportion of the property built by diaspora capital is built in second-tier cities, rural districts, and ancestral home regions — precisely the locations that FMBN's institutional product cannot reach.

This is not a criticism of FMBN. It is an observation about the inherent limits of any sovereign-backed mortgage product. The bank must underwrite properties whose title can be verified, whose location can be inspected, whose collateral value can be enforced. These constraints inevitably narrow the eligible universe. The full demand exists; the structured supply addresses a fraction of it. The remainder is financed informally, in cash, with no leverage.

The Diaspora NHF Mortgage product, in this light, is best understood not as a complete answer but as a proof of concept. It demonstrates that a Nigerian in Manchester is willing to engage with a structured financial product to acquire property in Lagos, provided the terms are reasonable. It does not demonstrate that the formal financial system can serve the full range of what that Nigerian actually wants to build. The gap between the two — between what FMBN can finance and what the diaspora actually invests in — is the space in which the next generation of diaspora credit infrastructure will be built.

V. The comparable elsewhere

FMBN is not the only diaspora-targeted mortgage system in operation, and the comparable cases illuminate what is possible and what is not.

Bank Al-Maghrib, the central bank of Morocco, supervises a network of products marketed to Moroccans Residing Abroad — known by their French acronym, MRE. Attijariwafa Bank, the country's largest financial institution, operates a dedicated MDM Plus product line offering mortgages denominated in dirham at rates that, depending on the borrower profile, range between five and seven per cent.[^17] BMCE Bank of Africa and the Banque Centrale Populaire operate equivalent products. The Moroccan diaspora, estimated at five million globally and concentrated in France, Spain, and the Netherlands, generates remittance flows exceeding eleven billion dollars annually. A substantial proportion of those flows passes through formal mortgage products. The Moroccan system works because the state has explicitly prioritised it: dedicated bank branches in major diaspora destinations, simplified administrative requirements, and tax incentives for repatriated savings invested in property all reduce the friction.

The Indian diaspora system is older and structurally different. The Reserve Bank of India does not directly subsidise mortgages, but it operates a category of accounts — Non-Resident External, Non-Resident Ordinary, Foreign Currency Non-Resident — that permit Indians abroad to hold savings in foreign currency, invest in domestic instruments, and borrow against Indian assets. The State Bank of India, HDFC, ICICI, and a long list of private and public-sector banks offer mortgage products to NRIs at rates ranging between eight and ten per cent.[^18] The Indian system processes more than one hundred billion dollars in annual remittances. It is the largest formal diaspora financial infrastructure in the world. It works because India is a high-income remittance corridor, its banking system is deep, and the NRI product range has been built over four decades.

The Singapore model is different again. Singapore is not a remittance corridor in the conventional sense; its diaspora is small relative to its population. The Housing Development Board's scheme — financed through the Central Provident Fund — has nevertheless produced the world's highest formal home-ownership rate, around eighty-nine per cent, demonstrating that mandatory long-duration savings can fund a national mortgage system at scale.[^19]

What these comparable systems share is sovereign backing. Moroccan banks operate under explicit state encouragement. Indian banks operate within a regulatory framework designed to capture diaspora capital. Singapore's HDB operates as an arm of the state. Each system works because the state has made a strategic decision to mobilise diaspora or domestic capital for housing, and has built the institutional architecture to do so.

This is what FMBN shares with these systems. It is also what FMBN — and every other sovereign-backed diaspora mortgage scheme — cannot scale beyond its own corridor. A Nigerian system cannot serve Filipinos. A Moroccan system cannot serve Argentines. Each scheme is constrained to the population whose state has decided to subsidise it. The diasporas whose home governments have made no such decision — and they constitute the majority of the global diaspora — have no equivalent.

VI. What FMBN tells us about what comes next

The lessons that emerge from FMBN's two decades of operation are precise.

First, the demand is real and price-sensitive. When a single-digit rate is offered to a population accustomed to twenty-five per cent commercial rates, take-up is constrained only by the supply of capital and the operational capacity of the lender. FMBN's Home Renovation programme reaching nearly thirty thousand beneficiaries in two years demonstrates this clearly.

Second, the sovereign-backed funding base is the bottleneck. The 1992 NHF Act mobilised mandatory contributions across the entire formal economy. The 2020 amendment that made private-sector contributions voluntary shrank the base. As the formal labour force shifts toward private and informal employment, the model's funding capacity will continue to erode without further reform. The structural dependence on payroll mandates means that any future scaling of the FMBN model requires renewed political consensus around mandatory contribution — a politically difficult proposition in any administration.

Third, the model does not translate cross-corridor. FMBN is structured for Nigerians, by Nigerians, with assets located in Nigeria. It cannot, by design, finance a Nigerian in Manchester to buy a property in Côte d'Ivoire. It cannot finance a Ghanaian in London to buy a property in Accra. Each diaspora requiring a similar product would require a parallel institutional architecture, with its own funding base, regulatory framework, and operational capacity. The bilateral effort to build such institutions across every relevant corridor is, simply, not going to happen.

Fourth, the institutional form is restrictive. FMBN can only finance properties whose title can be verified through Nigerian registries, in cities where the bank operates branches and can inspect collateral. This excludes the majority of properties the diaspora actually invests in — properties in smaller cities, in ancestral villages, in regions where formal title infrastructure is incomplete.

What follows from these observations is not a critique of FMBN. The bank is doing what an institution of its type can do, given the funding and operational constraints under which it operates. What follows is rather a statement about what the next generation of diaspora credit infrastructure will need to look like, if it is to address the gap that FMBN-style institutions cannot.

The next generation will need to be funded by something other than a national payroll levy. The funding base must be available across diasporas, not contingent on any one government's housing policy. The natural candidate is the diaspora's own capital — the stablecoin balances, the foreign-currency savings, the dollar-denominated remittance flows that exist in growing volumes in Chainalysis and World Bank datasets.[^20]

The next generation will need to be regulated outside the source country, because no source-country regulator can supervise a credit institution operating across multiple jurisdictions simultaneously. The natural candidate is the European AIFMD framework, which permits the constitution of cross-border credit funds with passporting rights across the European Economic Area.[^21]

The next generation will need to take collateral in a form that can be enforced across jurisdictions without requiring local property registries to perform legal magic. The natural candidate is collateral held in regulated custody — stablecoin balances at supervised European custodians, or financial-asset collateral at regulated depositary banks — rather than collateral consisting of the property being financed.

None of this displaces FMBN. The Nigerian government's commitment to subsidising single-digit mortgages for Nigerians remains a national choice and a useful one. What it does is recognise that the FMBN model is an exception, that the exception is structurally limited, and that the gap left by the exception will require a different institutional architecture to fill.

VII. The end-state

FMBN's existence has demonstrated, over more than three decades, that the diaspora is a credit-worthy borrower when the terms are right. The bank's continued operation, despite the funding-base erosion and the operational complexity, demonstrates that the demand for diaspora-targeted housing finance is durable. The bank's limits — geographic, institutional, financial — demonstrate that the conventional architecture of national mortgage institutions cannot, by itself, scale to meet that demand.

The end-state of the diaspora credit market will not be a network of FMBN equivalents in every source country. The political economics of mandatory contribution preclude that. The end-state will be a hybrid: national institutions like FMBN serving the populations their governments have decided to subsidise, alongside private credit infrastructure — regulated, multi-jurisdiction, capitalised by the diaspora's own savings — serving everyone else.

In Lagos, the FMBN's nine per cent will remain available to those who qualify and within the geographies the bank can underwrite. In Manchester, the Nigerian doctor who cannot qualify, or who wishes to build in a village FMBN does not service, will have a different product to consider. That product does not yet exist at scale. Its components exist. The institutions building it are visible, even if early. The financial regulators of the European Union have, over the past three years, completed the legal infrastructure necessary to make it operational at scale.

FMBN's lesson is the demand. The infrastructure to meet that demand at scale will be built somewhere else.
