UBA climbs to 15th in Africa's top 100 banks as Nigerian lenders' capital surges to $15.2B

United Bank for Africa has moved up five spots in Africa's banking hierarchy, now sitting at 15th among the continent's hundred largest banks. The climb reflects a broader surge in Nigerian banking strength: the country's lenders collectively hold $15.2 billion in Tier 1 capital as of 2026, up sharply from $10.3 billion the year before. That 48 percent jump came after the Central Bank of Nigeria imposed new capital requirements, forcing banks to shore up their reserves and reshape their balance sheets.

UBA's own numbers tell the story most clearly. The bank's Tier 1 capital nearly doubled, growing from $1.7 billion to $2.7 billion. That expansion was enough to vault it past several competitors and land it in the top twenty across the continent. The improvement stands out partly because other Nigerian banks, despite their own capital gains, did not climb as steeply. Access Bank increased its capital from $2 billion to $2.6 billion but actually fell two places, dropping from 14th to 17th. Zenith Bank added $600 million to its capital base yet slipped four positions to 20th. GTBank moved in the opposite direction, jumping five places to 25th as its capital rose from $1.1 billion to $1.77 billion. Stanbic IBTC posted the most dramatic leap among returning banks, jumping 35 places from 80th to 45th after its capital more than doubled from $290 million to $735 million.

The driver behind these shifts was the Central Bank of Nigeria's recapitalisation mandate. Banks holding international licences now must maintain a minimum of ₦500 billion in capital, compared to ₦200 billion for national banks and ₦50 billion for regional ones. The requirement forced lenders to raise money through rights issues, public offerings, and other capital-raising exercises. The result was not just bigger balance sheets but greater capacity to absorb losses, expand lending, and pursue opportunities across the African continent. Nigerian banks were not alone in strengthening themselves. West and Central African lenders as a group saw their combined capital rise 32 percent to $19.6 billion.

The broader African banking landscape shows other regional powers holding their ground. South Africa's Standard Bank retained first place, its Tier 1 capital climbing from $13.2 billion to $15.7 billion, with assets of $217.7 billion and net profit of $3.4 billion—the highest among all commercial banks in the ranking. Egyptian banks surged collectively, their combined capital rising to $31 billion from $22.6 billion. Commercial International Bank of Egypt climbed from 17th to 12th, its capital jumping from $1.91 billion to $3.13 billion. Morocco's banking sector remained entrenched in the top tier, with Attijariwafa Bank at third, Banque Centrale Populaire at sixth, and Bank of Africa-BMCE at ninth.

The African Banker magazine, which produces the ranking, noted that currency movements and differences in how banks report their finances can shift positions without necessarily reflecting changes in actual business performance. The magazine also flagged a critical challenge ahead: Africa's largest banks now hold stronger balance sheets, but they must deploy that capital toward infrastructure financing, support for small businesses, deeper financial inclusion, and expanded cross-border trade. The African Development Bank has estimated that the continent faces an unmet trade finance gap of between $74 billion and $92 billion—a measure of the opportunity waiting for banks with sufficient capital to seize it. Nigerian banks, newly fortified, are positioned to compete for that business.
