Nigeria's external balance sheet is defined by structural volatility: overreliance on crude oil exports, massive but informally-channeled remittances, and highly sensitive FDI flows.

The Oil Export Dependency

Crude oil/gas = ~90% of merchandise export earnings. NNPC and international oil companies (IOCs) generate FX deposited with CBN as the core of foreign reserves. Structural irony: Nigeria historically imported all refined petroleum despite being a major crude exporter, neutralizing trade balance benefits of high oil prices.

Diaspora Remittance Channels

~$20B annually, formal channels. Historical leakage to Hawala and parallel market due to official rate overvaluation. CBN reforms: IMTOs allowed to pay in USD cash or domiciliary accounts at market rates, significantly increasing formal banking volumes.

FDI Barriers and Private Investment

Nigeria struggles with low private FDI outside oil/gas due to: regulatory unpredictability, foreign exchange repatriation restrictions (historically), infrastructure deficits, and security challenges. Capital importation collapsed from $24B (2019) to under $4B (2022) before NAFEM reforms.

Portfolio Investment Dynamics

Foreign portfolio investors attracted by high domestic yields on T-Bills and OMO bills. Highly sensitive to CBN policy shifts and naira stability. CBN OMO bills offered to FPIs as a dollar-attracting mechanism, creating high-yield carry trade dynamics.
