Three of Nigeria’s five biggest banks — Zenith, UBA and Access — trade at or below book value, meaning the market values them at less than the accounting worth of their net assets.
FirstRand and Standard Bank, by contrast, trade at more than double book, a premium investors typically reserve for banks with higher, more durable returns on equity and clearer paths to loan-book growth.
The Macro Backdrop: Two Economies, Two Banking Systems
The valuation gap tracks a wider structural divide between the two economies. Nigeria’s GDP, at an estimated $377 billion, is smaller than South Africa’s roughly $479 billion economy, even though Nigeria’s population of more than 240 million dwarfs South Africa’s approximately 63 million — data compiled by MoneyCentral shows. But the more telling difference is in how deeply banking penetrates each economy.
Nigeria’s domestic bank credit extended to the private sector equals just 9.4% of GDP — among the lowest ratios in Africa and a fraction of the levels seen in comparable emerging markets such as Kenya (31.6%) and Egypt (28.3%), according to the African Development Bank’s 2026 African Economic Outlook.
South Africa’s equivalent ratio stood at 57.74% in the most recent World Bank series, more than six times Nigeria’s level.
That gap in credit intensity shows up in each country’s growth accounting too. Nigeria’s financial and insurance sub-sector contributed roughly 6% to rebased nominal GDP as of early 2025, even as the wider services sector accounted for more than half of output, according to sector data cited from the National Bureau of Statistics.
South Africa’s finance, insurance and business-services complex is a substantially larger share of a smaller economy — estimated at between roughly 15% and 21% of GDP depending on methodology, according to South African Reserve Bank and Making Finance Work for Africa data.
Historically, the disparity in banking depth goes back at least a decade: South African banks held total assets of roughly $352.3 billion (R3.7 trillion) in 2013 — effectively the size of the entire economy at the time — while Nigerian bank assets stood at just 41.8% of GDP over a comparable period, data compiled by MoneyCentral shows.
In other words, South Africa’s banking system was already balance-sheet-deep enough to match its GDP more than a decade ago; Nigeria’s is still less than half the size of its economy today.
The Inclusion Gap: An Untapped Market
Perhaps the starkest divergence — and the one most often cited by bulls on Nigerian banking equities — is financial inclusion. The Central Bank of Nigeria estimates that 26% of Nigeria’s adult population remained excluded from formal financial services at the end of 2025, even after inclusion climbed to roughly 74% from 64% in 2020 under the CBN’s National Financial Inclusion Strategy.
The CBN’s Nigeria Payments System Vision 2028 targets 95% inclusion by the end of the decade.
By contrast, South Africa’s Financial Sector Conduct Authority puts exclusion at just 2% of the population — about 7 million adults out of a much smaller base — with 37.3 million adults formally banked as of early 2025. Other South African Reserve Bank research places overall financial inclusion above 80%, well ahead of the sub-Saharan African average.
For a country of Nigeria’s scale, that unbanked population — tens of millions of adults — represents a large addressable market that South African banks, operating in an already near-saturated system, do not have. Analysts argue that is precisely the kind of secular growth runway that should, in time, support higher valuations for Nigerian lenders as digital banking, fintech partnerships and agent-banking networks pull more of the population into the formal system.
The Devaluation Drag: A Decade of Lost Dollar Value
Currency depreciation has done more damage to Nigerian bank valuations, in dollar terms, than any operational shortfall.
The combined market capitalization of Nigeria’s top five lenders — FirstHoldCo, Zenith Bank, GTCO, UBA and Access Bank — stood at $16.4 billion (then ₦2.664 trillion) in July 2014, data compiled by MoneyCentral shows.
Today, that combined value has fallen to roughly $13.72 billion, even though the naira-denominated figure has risen sharply to nearly ₦19 trillion — a function of the naira’s collapse from roughly ₦160–176 per dollar in 2014 to more than ₦1,340–1,400 per dollar in 2026.
FirstRand alone tells the opposite story. South Africa’s largest lender by market value has grown from a $23.1 billion (R243.27 billion) market cap in 2014 to roughly $32 billion today — meaning one South African bank is now worth more in dollar terms than all five of Nigeria’s largest lenders combined, data compiled by MoneyCentral shows.
The lesson for investors is that Nigerian bank earnings and book values, even when growing briskly in naira terms, have to run simply to stand still in dollar terms — a dynamic that likely explains part of the persistent valuation discount demanded by foreign portfolio investors.
The Bottom Line
Nigeria’s tier-one banks are cheap by almost every conventional yardstick — trading at or below book value in three of five cases, versus multiples exceeding 2x for their South African counterparts.
That discount exists for real reasons: shallow credit penetration, a financial-services sector that punches below its weight relative to the size of the economy, a naira that has shed the vast majority of its dollar value over the past decade, and a currency-conversion drag that keeps eroding hard-currency valuations even as local shareholders earn strong naira returns.
But the same data that explains the discount also frames the opportunity.
A 240-million-person economy with private credit at under 10% of GDP and more than a quarter of adults still unbanked has more headroom to grow into higher valuations than an already-mature market like South Africa’s.
As Nigerian banks continue recapitalizing under the CBN’s new minimum capital regime, digitize distribution, and — as FirstHoldCo’s 257.8% rally this year suggests investors are starting to price in — execute credible turnarounds, the re-rating gap with South African peers may be one of the more persistent value trades left in African equities.
