Nigeria's Currency Gains Mask Deeper External Sector Fragility as Investors Face a Structural Test

Nigeria's naira has staged a remarkable recovery in recent weeks, appreciating to N1,345 per dollar—its strongest level in a month—while also holding firm against the euro at N1,556 and the pound at N1,844. For European investors monitoring Africa's largest economy, this currency strength signals monetary stability and could suggest improving macroeconomic fundamentals. However, beneath this superficially encouraging headline lies a more sobering reality: Nigeria's external sector is deteriorating faster than its currency appreciation suggests.

The Central Bank of Nigeria's 2025 Balance of Payments report reveals the uncomfortable truth. Nigeria's overall BoP surplus crashed 38.1 percent year-on-year to just $4.23 billion, down from $6.83 billion in 2024. More alarming, the current account surplus—the broadest measure of external health—fell 26 percent to $14.04 billion from $19.03 billion. These declines occurred despite currency reforms that the CBN credits with stabilising the naira through forced foreign exchange unification and institutional discipline.

The culprit is unambiguous: collapsing commodity revenues. Crude oil exports declined 14.41 percent to $31.54 billion in 2025, a structural vulnerability that exposes Nigeria's persistent failure to diversify its export base. Simultaneously, foreign portfolio investment dried up, plummeting 48.3 percent to just $8.04 billion—a signal that international capital is becoming increasingly cautious about Nigeria's investment climate despite government rhetoric on reforms.

What sustains the naira's apparent strength, then? The CBN has raised nearly N3 trillion through Treasury Bills auctions in just two weeks, indicating aggressive domestic borrowing to defend the currency. This is not sustainable. The government is essentially cannibalising its domestic capital market to maintain an exchange rate that masks underlying weakness. For European investors accustomed to transparent currency regimes, this strategy carries significant political economy risks.

The broader context compounds concerns. Nigeria's defence budget consumed approximately N32.88 trillion over 15 years—12.5 percent of total government spending—yet the country remains trapped in protracted insecurity that now extends beyond the northeast to the south and southwest. The recent Maiduguri suicide bombings that killed 23 civilians and wounded over 100 exemplify a security crisis that drains resources without generating productive returns. Vice President Kashim Shettima's hospital visits and promises of "full peace" reflect the government's awareness that security failures directly undermine investor confidence and economic performance.

Positively, the IMF projects that Nigeria will overtake South Africa as Africa's top contributor to global growth in 2026, and the government's newly launched Industrial Policy allocates five percent of GDP to manufacturing finance—a structural reform signal. The Pan-African Manufacturers Association welcomed this move as potentially transformative. Additionally, the Central Bank's currency unification reforms, though painful, have begun attracting comment as institutional anchors worth protecting from political reversal.

Yet the data tells a cautionary tale. External reserves may be building nominally, but they are being deployed defensively rather than offensively. The naira's strength is a policy achievement, not a market verdict. Foreign investors are voting with their feet—portfolio inflows collapsed nearly 50 percent—suggesting they see currency strength as a lagging indicator of deeper problems rather than a leading indicator of recovery.

For European entrepreneurs evaluating Nigeria, the question is whether to view current valuations as a buying opportunity in a currency that appears stabilised but fragile, or as a warning sign that the CBN is fighting structural headwinds with tactical interventions.
