Nigeria ranks 44th worldwide and third in Africa in factory output.
The oil boom of the 1970s led Nigeria to neglect its strong agricultural and light manufacturing bases in favor of an unhealthy dependence on crude oil. In 2000, oil and gas exports accounted for more than 98% of export earnings and about 83% of federal government revenue. New oil wealth, the concurrent decline of other economic sectors, and a lurch toward a statist economic model fueled massive migration to the cities and led to increasingly widespread poverty, especially in rural areas. A collapse of basic infrastructure and social services since the early 1980s accompanied this trend. By 2000,
Nigeria's per capita income had plunged to about one-quarter of its mid-1970s high, below the level at independence. Along with the endemic malaise of Nigeria's non-oil sectors, the economy continues to witness massive growth of "informal sector" economic activities, estimated by some to be as high as 75% of the total economy.The oil boom of the 1970s led Nigeria to neglect its strong agricultural and light manufacturing bases in favor of an unhealthy dependence on crude oil.

Nigeria's proven oil reserves are estimated to be 35 billion barrels (5.6×109 m3); natural gas reserves are well over 100 trillion cubic feet (2,800 km3). Nigeria is a member of the Organization of Petroleum Exporting Countries (OPEC), and in mid-2001, its crude oil production was averaging around The types of crude oil exported by Nigeria are Bonny light oil, Forcados crude oil, Qua Ibo crude oil and Brass River crude oil. Poor corporate relations with indigenous communities, vandalism of oil infrastructure, severe ecological damage, and personal security problems throughout the Niger Delta oil-producing region continue to plague Nigeria's oil sector. Efforts are underway to reverse these troubles. In the absence of government programs, the major multinational oil companies have launched their own community development programs. A new entity, the Niger Delta Development Commission (NDDC), has been created to help catalyze economic and social development in the region. Although it has yet to launch its programs, hopes are high that the NDDC can reverse the impoverishment of local communities. The U.S. remains Nigeria's largest customer for crude oil, accounting for 40% of the country's total oil exports; Nigeria provides about 10% of overall U.S. oil imports and ranks as the fifth-largest source for U.S. imported oil.
The United Kingdom is Nigeria's largest trading partner followed by the United States. Although the trade balance overwhelmingly favors Nigeria, thanks to oil exports, a large portion of U.S. exports to Nigeria is believed to enter the country outside of the Nigerian government's official statistics, due to importers seeking to avoid Nigeria's excessive tariffs. To counter smuggling and under-invoicing by importers, in May 2001, the Nigerian government instituted a full inspection program for all imports, and enforcement has been sustained. On the whole, Nigerian high tariffs and non-tariff barriers are gradually being reduced, but much progress remains to be made. The government also has been encouraging the expansion of foreign investment, although the country's investment climate remains daunting to all but the most determined. The stock of U.S. investment is nearly $7 billion, mostly in the energy sector. Exxon Mobil and Chevron are the two largest U.S. corporations in offshore oil and gas production. Significant exports of liquefied natural gas started in late 1999 and are slated to expand as Nigeria seeks to eliminate gas flaring by 2008.
Oil dependency, and the allure it generated of great wealth through government contracts, spawned other economic distortions. The country's high propensity to import means roughly 80% of government expenditures is recycled into foreign exchange. Cheap consumer imports, resulting from a chronically overvalued Naira, coupled with excessively high domestic production costs due in part to erratic electricity and fuel supply, pushed down utilization of industrial capacity to less than 30%. Many more Nigerian factories would have closed except for relatively low labor costs (10%–15%). Domestic manufacturers, especially pharmaceuticals and textiles, have lost their ability to compete in traditional regional markets. However, there are signs that some manufacturers have begun to improve competitiveness.
The pump price of P.M.S. in Nigeria currently stands at 97 naira, but some fueling stations in Nigeria, especially in towns far from the state capitals, tend to sell the product at a much higher price, ranging from 110 naira to 140 naira. An initial increase in the price of petroleum on New Year day from 65 naira to 138 naira triggered off a total strike and massive protests across the country. President Goodluck Ebele Jonathan later reached an agreement with the Nigerian Labour Congress and reduced the pump price to 97 naira.
In April 2006, Nigeria became the first African country to fully pay off its debt owed to the Paris Club. However, this was structured as a debt writeoff of approximately $18 billion and a cash payment of approximately $12 billion.
In the light of highly expansionary public sector fiscal policies in 2001, the government sought ways to head off higher inflation, leading to the implementation of stronger monetary policies by the Central Bank of Nigeria (CBN) and underspending of budgeted amounts. As a result of the CBN's efforts, the official exchange rate for the Naira has stabilized at about 112 Naira to the dollar. The combination of CBN's efforts to prop up the value of the Naira and excess liquidity resulting from government spending led the currency to be discounted by around 20% on the parallel (non-official) market. A key condition of the Stand-by Arrangement has been closure of the gap between the official and parallel market exchange rates. The Inter Bank Foreign Exchange Market (IFEM) is closely tied to the official rate. Under IFEM, banks, oil companies, and the CBN can buy or sell their foreign exchange at government influenced rates. Much of the informal economy, however, can only access foreign exchange through the parallel market. Companies can hold domiciliary accounts in private banks, and account holders have unfettered use of the funds.
Expanded government spending also has led to upward pressure on consumer prices. Inflation which had almost disappeared in April 2000 reached 14.5% by the end of the year and 18.7% in August 2001. In 2000, high oil prices resulted in government revenue of over $16 billion, about double the 1999 level. State and local governments demanded access to this "windfall" revenue, creating a tug-of-war between the federal government, which sought to control spending, and state governments desiring augmented budgets, preventing the government from making provision for periods of lower oil prices.
