Nigeria's financial architecture is anchored by the Central Bank of Nigeria (CBN), heavily influenced by crude oil revenue flows through NNPC, and increasingly shaped by a massive diaspora remittance corridor and a hyper-growth fintech sector.
The CBN operates an inflation-targeting framework using the Monetary Policy Rate (MPR). Key structural impediments: asymmetric corridor system, Cash Reserve Ratio (historically 32.5-45%), and fiscal dominance via Ways and Means overdrafts. Between 2015 and 2023, CBN extended over 22.7 trillion NGN in overdrafts to the Federal Government, fueling inflation. This was securitized into 40-year bonds at 9% in 2023.
Decades of multiple exchange rate windows (Official, I&E, SME, Parallel) created massive arbitrage spreads of 60-100%, capital flight, and FPI collapse from $24B (2019) to under $4B (2022). The June 2023 unification to NAFEM (willing buyer, willing seller) caused 70%+ naira devaluation but eliminated arbitrage and restored FPI confidence.
Oil accounts for ~90% of export earnings and 50%+ of federal revenue. The petrol subsidy regime consumed all NNPC remittances to FAAC for multiple months in 2022 — NNPC remitted zero. Subsidy removal in May 2023 freed trillions in monthly FAAC distributions but triggered acute inflation.
World Bank portfolio: one of its largest globally. SFTAS (State Fiscal Transparency) program reshaped sub-national fiscal discipline across all 36 states. Power Sector Recovery Program targeting electricity grid restructuring. IMF COVID-19 emergency financing ($3.4B RFI, 2020). IMF advocacy: exchange rate unification, subsidy rationalization, revenue mobilization (tax-to-GDP at 6-10%, among world's lowest).
~$20B annually, largest in Sub-Saharan Africa, ~4-5% of GDP. Naira 4 Dollar Scheme (2021): 5 NGN incentive per dollar via licensed IMTOs. Policy shift to direct USD payouts to domiciliary accounts significantly increased formal channel volumes.
~40% of adult Nigerians remain unbanked. Fintech unicorns: Flutterwave, Paystack (acquired by Stripe), OPay, Moniepoint, PalmPay. NIBSS Instant Payment (NIP) provides world-class real-time payment infrastructure. Agent banking networks (hundreds of thousands of POS terminals) have brought tens of millions into the digital financial ecosystem.
