Nigeria’s foreign exchange reserves have been a topic of much discussion and debate over the years. As Africa’s largest economy, Nigeria relies heavily on its foreign exchange reserves to support its currency, the naira, as well as to fund imports and manage external debt obligations. This article will provide a comprehensive overview of Nigeria’s foreign exchange reserves.


Nigeria’s foreign exchange reserves are assets held on reserve by the Central Bank of Nigeria (CBN) in foreign currencies. These reserves act as a buffer to stabilize the value of the naira against major currencies like the US dollar. The reserves include cash deposits, bonds, treasury bills and other government securities denominated in foreign currencies like the dollar, euro, yen and pound sterling.

Nigeria derives most of its foreign exchange earnings from the export of crude oil. Fluctuations in global crude oil prices directly impact the level of Nigeria’s reserves. When oil prices are high, more foreign currency flows in, boosting reserves. Lower oil prices lead to a drawdown of reserves to fund imports and defend the naira. The CBN constantly balances the need to maintain adequate reserves, while also meeting other objectives like supporting economic growth and managing inflation.

Nigeria’s foreign exchange reserves increased rapidly in the early 2000s, rising from just $7.5 billion in 2003 to over $53 billion by 2008. This was fueled by high oil prices, which reached $140 per barrel in 2008. Reserves continued rising, peaking at $62 billion in 2008 before falling during the Global Financial Crisis.

The 2014-2016 crash in oil prices caused reserves to plummet over 60% from almost $65 billion to just $23 billion by 2016. This slump in reserves limited the CBN’s capacity to defend the naira, leading to the implementation of capital controls and multiple devaluations. The naira fell from 197/$1 to over 305/$1 at the official rate.

Higher oil prices after 2016 provided some relief, with reserves recovering to over $40 billion by 2021. But reserves remain well below previous highs, standing at $39.6 billion as of July 2022 according to CBN data. Reserves cover 8.9 months of imports, which is higher than the 3 months international benchmark but remains below the CBN’s 15-month target.


Nigeria’s foreign exchange reserves comprise of:

Cash deposits

These are foreign currency cash balances held in reserve by the CBN. It includes deposits held at overseas banks at places like the Bank of England and Federal Reserve Bank of New York. These ready liquid assets allow the CBN to quickly intervene in currency markets during periods of volatility.


Bonds and treasury bills issued by creditworthy foreign governments like the US, UK and EU countries make up a portion of Nigeria’s reserves. These assets earn interest income and can also be sold easily when the CBN needs to raise foreign currency.


Physical gold held in foreign vaults also constitutes a small share of total reserves. Gold is a traditional reserve asset that offers diversification benefits because its value often rises when other assets fall.

IMF Reserve Position

This refers to the foreign exchange portion of Nigeria’s contribution to the International Monetary Fund (IMF) that can be drawn at notice. It represents Nigeria’s claims on the IMF in foreign currencies.


Special Drawing Rights (SDRs) are foreign exchange reserve assets created by the IMF to supplement member countries’ reserves. Nigeria was allocated about $2.3 billion in SDRs in 2021.

Other claims

Other claims include foreign currencies lent to domestic banks and outstanding receivables from foreign entities.


Nigeria’s foreign exchange reserves are managed by the CBN to achieve certain key objectives:

  • Currency intervention – The CBN utilizes reserves to influence the naira’s exchange rate against major currencies like the dollar. Selling reserves supplies foreign currency to the market, preventing or slowing down depreciation of the naira when demand outpaces supply.
  • Import cover – Reserves finance payments for critical imports like machinery, pharmaceuticals and petroleum products. Maintaining adequate import cover helps stabilize access to essential commodities.
  • External debt payments – Reserves are drawn down to service public external debt obligations when revenues are insufficient. This maintains good international credit ratings.
  • Investor confidence – Sizeable reserves signal economic strength and backing for the domestic currency, inspiring confidence in foreign investors and firms.
  • Exchange rate stability – Reserves allow the CBN to smooth out volatility and prevent large swings in the naira’s exchange value, creating stability for trade and investment.


The Central Bank of Nigeria is charged with managing the country’s reserves to meet stated objectives. The CBN uses reserves to regulate currency exchange rates and fund external obligations. However, reserves management has often been complicated by conflicting policy goals like exchange rate stability, inflation control and economic growth.

Key aspects of Nigeria’s reserves management include:

  • Monitoring reserve levels and currency inflows and outflows
  • Buying and selling of foreign exchange to control exchange rate movements
  • Rebalancing portfolio by altering reserve composition
  • Coordinating fiscal and monetary policy to either build up or draw down reserves
  • Making strategic decisions on currency regime (fixed, floating, pegged etc.)
  • Deploying reserves to settle foreign obligations like debt payments
  • Working closely with the fiscal authorities regarding reserves utilization

The CBN has adopted various foreign exchange management regimes ranging from fixed to floating rates and a hybrid system to balance policy objectives. While building reserves remains critical, utilization is equally important to derive optimal value.


Nigeria faces several challenges growing and managing its foreign exchange reserves including:

Reliance on oil exports

As an oil dependent economy, Nigeria’s foreign reserves are vulnerable to boom and bust cycles in crude oil prices. Oil accounts for over 90% of foreign exchange earnings. Global supply and demand factors outside Nigeria’s control determine oil prices and reserves.

Limited non-oil export capacity

Underdeveloped non-oil sectors limit the economy’s capacity to earn foreign currency beyond oil. Non-oil exports like cocoa, sesame, leather and cashews earn less than 3% of Nigeria’s foreign exchange.

Large imports

Nigeria’s huge import dependence drains reserves. Importing food, medicines, industrial machinery, chemicals and petroleum products depletes reserves. Weak domestic manufacturing forces reliance on imports.

Dollar shortages

Acute US dollar shortages arise when global oil prices fall. With fewer dollars in circulation, even critical imports become hard to finance. This increases demand pressure on reserves.

Exchange rate pressures

Maintaining multiple exchange rates has spawned shortages and widening parallel market exchange rate premiums. This puts pressure on reserves and the naira.

Capital flight

Substantial capital outflows by foreign investors, firms and locals seeking forex for overseas purposes also drains reserves. Periods of uncertainty trigger larger capital flight.


Nigeria’s foreign exchange reserves outlook remains tied to oil market developments. Sustained higher oil prices will allow further reserves accumulation. But reserves adequacy also depends on the economy’s import levels.

With the naira exchange rate more reflective of market conditions after recent reforms, the CBN may allow reserves flexibility to spur non-oil export growth. But depleted reserves after the 2014 oil crash will compel the CBN to remain cautious.

Diversifying Nigeria’s export base by boosting agriculture and manufacturing will reduce dependence on oil and stabilize reserves. Growing diaspora remittances can also provide forex beyond oil. But reversing deep-rooted structural imbalances will require long-term reforms.

In the near term, reserves will remain sensitive to movements in oil prices and global financial conditions. More flexible exchange rate management will help moderate depletion during external shocks. But Nigeria’s capacity to withstand oil price volatility remains tied to progress on economic diversification.


Nigeria’s foreign exchange reserves provide vital support for the naira and external sector stability. But maintaining adequate reserves has been challenged by volatile oil revenue, import dependence, dollar shortages, capital flight and exchange rate pressures.

While the CBN constantly calibrates reserves policies, Nigeria’s ability to build reserves will depend on boosting non-oil exports and diversifying foreign exchange inflows beyond oil. This requires deep structural reforms to improve competitiveness and reduce import dependence.

With oil prices beyond its control, Nigeria needs urgent economic diversification to generate sustainable forex earnings. Boosting domestic production will also curb export proceeds being used for imports. While reserves management provides short term relief, transforming the economy is vital for long term resilience and prosperity.
