Nigeria recorded an unexplained $12.4 billion discrepancy in its external accounts during the first half of 2026, offsetting much of the combined benefit of its current account surplus and net financial inflows, according to the World Bank’s latest Nigeria Development Update.

The bank said the discrepancy, recorded as “net errors and omissions” in the balance of payments, may partly reflect oil export earnings that were not repatriated to Nigeria. It did not establish that the entire amount represented repatriated oil revenue, nor did it identify the money as stolen or missing through proven wrongdoing.

The finding highlights a critical issue for Africa’s largest oil-producing economy: even when export earnings and foreign investment appear strong, the country needs accurate financial reporting and a reliable flow of foreign exchange into its domestic economy.

What the $12.4 billion figure actually means

The figure is an accounting discrepancy—not a confirmed bill for missing funds. In balance-of-payments statistics, net errors and omissions are used when recorded transactions and financial flows do not fully reconcile.

The World Bank said the gap may partly reflect oil export proceeds that were not brought back into Nigeria. Some export earnings may be retained in offshore accounts or used to meet existing obligations, including oil-backed financing arrangements. The bank did not quantify how much of the discrepancy could be attributed to these factors.

That distinction is important. The report raises questions about the visibility and repatriation of foreign earnings, but the available figures do not establish that $12.4 billion was stolen, concealed by a particular company or deliberately withheld.

Figures reported in the World Bank assessment and coverage of its October 2026 Nigeria Development Update.

Nigeria’s current account surplus increased to $12 billion, equivalent to about 7% of gross domestic product, during the first half of 2026. That compared with $8.6 billion in the corresponding period of 2025 and $5.5 billion in the second half of 2025. Higher oil prices and lower oil-import spending contributed to the improvement.

However, the unexplained discrepancy offset much of the benefit that the surplus and net financial inflows would otherwise have provided to foreign-reserve accumulation.

Why repatriated oil earnings matter

Oil remains a major source of Nigeria’s foreign exchange. When export proceeds return to the domestic financial system, they can support foreign-exchange liquidity, help businesses pay for imports and contribute to the country’s external buffers.

When proceeds are retained abroad or committed to other obligations, the benefit to Nigeria’s domestic foreign-exchange market may be more limited.

The World Bank identified oil pledges and existing financing arrangements as possible constraints on repatriation. Such arrangements can involve future export proceeds being committed to lenders or other obligations. The report did not establish the contribution of any individual company, financing agreement or transaction to the $12.4 billion figure.

The discrepancy therefore raises questions for policymakers and financial regulators about how comprehensively export receipts are recorded and reconciled, and how much foreign exchange from oil sales is available to support domestic economic activity.

Foreign reserves are rising, but investment flows carry risks

Nigeria’s gross international reserves rose from $45.5 billion at the end of 2025 to $53.8 billion at the end of August 2026. The World Bank said portfolio investment inflows were a major contributor to the increase.

The bank also highlighted a potential weakness in the composition of foreign-exchange inflows:

• Portfolio investment: Nigeria received $12.2 billion in net portfolio investment inflows during the first half of 2026.
• Direct investment: Direct investment liabilities fell 15% to $2.2 billion.
• Reliance on short-term capital: Foreign portfolio investment accounted for 45% of gross inflows through Nigeria’s foreign-exchange market between January and August, largely in fixed-income instruments.

Portfolio inflows can improve foreign-exchange supply and support reserves, but they can also reverse quickly if investors lose confidence, global interest rates change or perceived risks increase. Direct investment, by contrast, can involve longer-term commitments to businesses, productive assets and operations.

The World Bank said further reforms to improve market transparency, convertibility and predictability would help Nigeria attract more durable investment. It also noted that a more recent estimate of net reserves was not available for its assessment, limiting its ability to evaluate the usable reserve buffer.

The fiscal warning: Revenue is improving, but spending pressures remain

The report also raised concerns about Nigeria’s public finances.

Federal government revenue rose to ₦6.2 trillion in the first half of 2026, compared with ₦3.6 trillion in the same period of 2025. The federal fiscal deficit narrowed to ₦9.9 trillion from ₦11 trillion year-on-year. Yet the World Bank cautioned that unusually low reported capital expenditure affected the interpretation of the improvement.

Other figures in the report underline the pressure on government spending:

The bank warned that the consolidated fiscal deficit could widen to around 3.5% of GDP in 2026 as expenditure pressures increase. It also highlighted overlapping budget cycles, weak alignment between approved budgets and implementation capacity, and delays in expenditure reporting as problems affecting budget credibility.

The central issue is not simply whether government revenue has increased. It is whether revenue is converted into public investment and services while debt-service obligations remain manageable.

What should happen next?

The World Bank’s findings point to several priorities for Nigeria:

1. Improve reconciliation of external accounts. Relevant authorities should clarify the sources of the discrepancy as more complete data become available.
2. Strengthen transparency around oil proceeds. Better reporting of export earnings and commitments could help explain how oil receipts move through the financial system.
3. Attract more long-term investment. More predictable rules and stronger investor confidence could reduce dependence on short-term portfolio flows.
4. Improve foreign-exchange market transparency. Clearer reporting and more consistent market rules can help businesses and investors make decisions.
5. Strengthen budget execution. More credible budget calendars and timely expenditure reporting can help the government assess whether public spending is delivering results.

These are policy priorities, not evidence that a specific party, company or individual caused the discrepancy.

Note:

The World Bank’s $12.4 billion finding complicates the picture of Nigeria’s improving external position. The country recorded a larger current account surplus and rising gross reserves, but an unexplained balance-of-payments discrepancy offset much of the expected benefit from its external surplus and financial inflows.

The bank’s suggestion that repatriated oil proceeds may partly explain the gap is significant, but it is not proof that the entire amount represents missing oil revenue or criminal activity.

The next step should be transparent reconciliation, not speculation: Nigeria needs clearer information about its external transactions, stronger and more sustainable foreign-exchange inflows, and better execution of public spending so that improvements in economic indicators can translate into more reliable economic opportunities for citizens.
