In 1960, Nigeria had six banks. By 1980, it had 26. By 1985, it had 40. And by 1991 — just five years after the Structural Adjustment Program deregulated interest rates and licensing — Nigeria had 125 banks. This was not gradual growth; it was an explosion. The oil boom of the 1970s created a petrodollar flood that needed banking channels. The 1972 and 1977 Indigenization Decrees forced foreign banks to sell controlling stakes to Nigerians. State governments established their own banks. And a new generation of Nigerian entrepreneurs — many with no banking experience — discovered that a banking license was the fastest way to access oil wealth. By 1986, the banking sector had grown from a colonial duopoly into a chaotic, competitive, and increasingly fragile marketplace.

Thesis

The 1960–1986 era transformed Nigerian banking from a colonial utility into a national obsession. The 1972 and 1977 Indigenization Decrees transferred ownership from foreign to Nigerian hands, but they did not transfer expertise. State governments used banks machines. Federal officials used banks to warehouse petrodollars. And a new class of 'briefcase bankers' used licenses to speculate in foreign exchange, real estate, and import licenses. The banking boom of the 1970s and early 1980s was not driven by financial intermediation — it was driven by oil rents, political connections, and regulatory arbitrage. When oil prices collapsed in 1986, the sector had grown too fast, too thin, and too politically entangled to survive without massive intervention.

The 2,083% Growth in 26 Years

In 1960, Nigeria had 6 banks. By 1980, it had 26. By 1985, it had 40. By 1991, it had 125. The growth was driven by four factors: (1) The 1972 and 1977 Indigenization Decrees, which forced foreign banks to sell controlling stakes and opened the door to new entrants; (2) The oil boom, which created a flood of petrodollars that needed banking channels; (3) State governments, which established banks vehicles (by 1992, 25 of 66 commercial banks had state government majority stakes); and (4) The 1986 SAP deregulation, which liberalized interest rates and licensing, creating a 'banking bubble' where 43 new banks were licensed between 1986 and 1989 alone. By 1990, there were 151 different banking products in Nigeria — but most were simply repackaged foreign exchange arbitrage schemes.

Insight: Banking growth without financial deepening is just rent-seeking. Nigeria's 2,083% bank growth created institutions that collected deposits but did not lend productively. The 'banks' were often front companies for FX speculation.

The 1977 Indigenization Decree: 60% Nigerian Ownership

The Nigerian Enterprises Promotion Decree of 1977 (Indigenization Decree) required that 60% of equity in all banks be held by Nigerians. Foreign banks — BBWA (First Bank), Barclays (Union Bank), BIAO (Afribank), Standard Bank (UBA), and others — were forced to sell majority stakes to Nigerian investors and the federal government. By 1980, the federal government held equity in 17 of 20 commercial banks. State governments held stakes in 10. The 'big three' (First Bank, Union Bank, UBA) became majority Nigerian-owned. But the transfer of ownership did not include transfer of management expertise. Many new Nigerian directors lacked banking experience. Corporate governance collapsed. And the CBN, under pressure from political patrons, failed to enforce prudential standards.

Insight: Indigenization without institutional capacity is just changing the name on the door. Nigeria nationalized bank ownership but not bank governance. The result was a sector that looked Nigerian but behaved recklessly.

The 'Arm Chair Banking' Era

Before 1986, Nigerian banking was characterized as 'arm chair banking' — bankers sat in their offices and waited for customers to come to them. There was no marketing, no product innovation, no risk management. The 1986 SAP changed this by deregulating interest rates and introducing competition. But the new competition was not healthy. Banks engaged in 'interest rate wars' to attract deposits, offering rates they could not sustain. They financed speculative real estate and import licenses rather than manufacturing or agriculture. By 1989, the CBN had to impose a maximum spread of 7.5 percentage points between savings and prime lending rates to stop the predatory competition. The 'arm chair' era ended, but it was replaced by an 'aggressive banking' era that was equally destructive.

Insight: The transition from 'arm chair' to 'aggressive' banking was not a transition from bad to good; it was a transition from lazy risk to active risk. Both eras lacked the core banking discipline: lending to creditworthy borrowers for productive purposes.

Closing Reflection

By 1986, Nigeria had 40 banks (28 commercial, 12 merchant) with 1,394 branches. Total banking system assets had grown from £123 million in 1980 to N123.6 billion by 1985. But the quality of assets was deteriorating. Non-performing loans were rising. Insider abuse was rampant. And the CBN — which had grown from a colonial institution into a powerful but politically compromised regulator — was struggling to supervise a sector that had expanded far beyond its capacity. The Structural Adjustment Program of 1986 would not merely devalue the naira; it would expose the structural fragility of a banking system built on oil rents rather than financial discipline.
