The economy of Angola remains heavily influenced by the effects of four decades of conflict in the last part of the 20th century, the war for independence from Portugal (1961–75) and the subsequent civil war (1975–2002). Poverty since 2002 is reduced over 50% and a third of the population relies on subsistence agriculture. Since 2002, when the 27-year civil war ended, government policy prioritized the repair and improvement of infrastructure and strengthening of political and social institutions. During the first decade of the 21st century, Angola's economy was one of the fastest-growing in the world, with reported annual average GDP growth of 11.1 percent from 2001 to 2010. High international oil prices and rising oil production contributed to strong economic growth, although with high inequality, at that time. 2022 trade surplus was $30 billion, compared to $48 billion in 2012.
The economy of Brunei, a small and wealthy country, is a mixture of foreign and domestic entrepreneurship, government regulation and welfare measures, and village traditions. It is almost entirely supported by exports of crude oil and natural gas, with revenues from the petroleum sector accounting for over half of GDP. Per capita GDP is high, and substantial income from overseas investment supplements income from domestic production. The government provides for all medical services and subsidizes food and housing. The government has shown progress in its basic policy of diversifying the economy away from oil and gas. Brunei's leaders are concerned that steadily increased integration in the world economy will undermine internal social cohesion although it has taken steps to become a more prominent player by serving as chairman for the 2000 APEC forum. Growth in 1999 was estimated at 2.5% due to higher oil prices in the second half.
The economy of Colombia is the fourth largest in Latin America as measured by gross domestic product and the third-largest economy in South America. Throughout most of the 20th century, Colombia was Latin America's 4th and 3rd largest economy when measured by nominal GDP, real GDP, GDP (PPP), and real GDP at chained PPPs. Between 2012 and 2014, it became the third largest in Latin America by nominal GDP. As of 2024, the GDP (PPP) per capita has increased to over US$19,000, and real gross domestic product at chained PPPs increased from US$250 billion in 1990 to over US$1 trillion in 2024. Poverty levels were as high as 65% in 1990, but decreased to under 30% by 2014, and 27% by 2018. They decreased by an average of 1.35% per year since 1990.
The economy of Equatorial Guinea has traditionally been dependent on commodities such as cocoa and coffee, but is now heavily dependent on petroleum due to the discovery and exploitation of significant oil reserves in the 1980s. In 2017, it graduated from "Least Developed Country" status, one of six Sub-Saharan African nations that managed to do so.
The economy of Iraq is dominated by the oil sector, which provided 89% of foreign exchange earnings in 2024. During its modern history, the oil sector has provided about 99.7% of foreign exchange earnings. Iraq's hitherto agrarian economy underwent rapid development following the 14 July Revolution in 1958 which overthrew the Hashemite Iraqi monarchy. It had become the third-largest economy in the Middle East by 1980. This occurred in part because of the government's successful industrialization and infrastructure development initiatives led by Saddam Hussein in the 1970s, which included irrigation projects, railway and highway construction, and rural electrification.
The economy of Kazakhstan is the largest in Central Asia in both absolute and per capita terms. As of 2023, Kazakhstan attracted more than US$370 billion of foreign investments since becoming an independent republic after the dissolution of the former Soviet Union.
The economy of Senegal is driven by mining, construction, tourism, fishing and agriculture, which are the main sources of employment in rural areas, despite abundant natural resources in iron, zircon, gas, gold, phosphates, and numerous oil discoveries recently. Senegal's economy gains most of its foreign exchange from fish, phosphates, groundnuts, tourism, and services. As one of the dominant parts of the economy, the agricultural sector of Senegal is highly vulnerable to environmental conditions, such as variations in rainfall and climate change, and changes in world commodity prices.
The economy of Seychelles is based on fishing, tourism, processing of coconuts and vanilla, coir rope, boat building, printing, furniture and beverages. Agricultural products include cinnamon, sweet potatoes, cassava (tapioca), bananas, poultry and tuna.
The economy of Tanzania is a lower-middle income economy that is centered around Manufacturing, Tourism, Agriculture, and financial services. Tanzania's economy has been transitioning from a planned economy to a market economy since 1985. Although total GDP has increased since these reforms began, GDP per capita dropped sharply at first, and only exceeded the pre-transition figure in around 2007.
The economy of Trinidad and Tobago is the third wealthiest in the Caribbean and the fifth-richest by GDP (PPP) per capita in the Americas. Trinidad and Tobago is recognised as a high-income economy by the World Bank. Unlike most of the English-speaking Caribbean, the country's economy is primarily industrial, with an emphasis on petroleum and petrochemicals. The country's wealth is attributed to its large reserves and exploitation of oil and natural gas.
The economy of Guyana is one of the fastest growing economies in the world, with a gross domestic product (GDP) growth of 19.9% in 2021. In 2024, Guyana had a per capita gross domestic product of Int$80,137 and an average GDP growth of 4.2% over the previous decade. Guyana's economy was transformed in 2015 with the discovery of an offshore oil field in the country's waters about 190 km from Georgetown, making the first commercial-grade crude oil draw in December 2019, sending it abroad for refining.
The Organization of the Petroleum Exporting Countries is a cartel enabling the co-operation of leading oil-producing and oil-dependent countries in order to collectively influence the global oil market and maximize profit. It was founded on 14 September 1960, in Baghdad by the first five members which are Iran, Iraq, Kuwait, Saudi Arabia, and Venezuela. The organization, which currently comprises 12 member countries, accounted for 38 percent of global oil production, according to a 2022 report. Additionally, it is estimated that 79.5 percent of the world's proven oil reserves are located within OPEC nations, with the Middle East alone accounting for 67.2 percent of OPEC's total reserves.
The economy of the Middle East is very diverse, with national economies ranging from hydrocarbon-exporting rentiers to centralized socialist economies and free-market economies. The region is best known for oil production and export, which significantly impacts the entire region through the wealth it generates and through labor utilization. In recent years, many of the countries in the region have undertaken efforts to diversify their economies.
The price of oil, or the oil price, generally refers to the spot price of a barrel of benchmark crude oil—a reference price for buyers and sellers of crude oil such as West Texas Intermediate (WTI), Brent Crude, Dubai Crude, OPEC Reference Basket, Tapis crude, Bonny Light, Urals oil, Isthmus, and Western Canadian Select (WCS). Oil prices are determined by global supply and demand, rather than any country's domestic production level.
The economic history of Ecuador covers the development of Ecuador's economy throughout its history, beginning with colonization by the Spanish Empire, through independence and up to the 21st century.
The 1970s energy crisis occurred when the Western world, particularly the United States, Canada, Western Europe, Australia, and New Zealand, faced substantial petroleum shortages as well as elevated prices. The two worst crises of this period were the 1973 oil crisis and the 1979 energy crisis, when, respectively, the Yom Kippur War and the Iranian Revolution triggered interruptions in Middle Eastern oil exports.
Iran is an energy superpower and the petroleum industry in Iran plays an important part in it. In 2004, Iran produced 5.1 percent of the world's total crude oil, which generated revenues of US$25 billion to US$30 billion and was the country's primary source of foreign currency. At 2006 levels of production, oil proceeds represented about 18.7% of gross domestic product (GDP). However, the importance of the hydrocarbon sector to Iran's economy has been far greater. The oil and gas industry has been the engine of economic growth, directly affecting public development projects, the government's annual budget, and most foreign exchange sources.
OQ, formerly known as Oman Oil Company, is an energy investment company headquartered in Muscat, Oman. It is a wholly owned subsidiary of the Government of Oman through the Oman Investment Authority state-owned enterprise.
Energy in Qatar describes energy production, consumption, and policies of the State of Qatar. The International Monetary Fund ranked Qatar as having the fifth highest GDP per capita in 2016 with a 60,787 USD per capita nominal GDP over a population of 2.421 million inhabitants. In 2014, oil and natural gas production made up 51.1% of Qatar's nominal GDP. Thus, Qatar has a worldwide high ranking of per capita GDP due to its significance production and exports in both crude oil and natural gas in proportion to its relatively small population.
Energy use in Oman was 381 TWh in 2020, almost double the consumption in 2010.
