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 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 Jordan is classified as a lower middle income economy. Jordan's GDP per capita rose by 351% in the 1970s, declined 30% in the 1980s, and rose 36% in the 1990s. After King Abdullah II's accession to the throne in 1999, liberal economic policies were introduced. Jordan's economy had been growing at an annual rate of 8% between 1999 and 2008. However, growth has slowed to 2% after the Arab Spring in 2011. The substantial increase of the population, coupled with slowed economic growth and rising public debt led to a worsening of poverty and unemployment in the country. As of 2023, Jordan has a GDP of US$50.85 billion, ranking it 89th worldwide.
The economy of Libya depends primarily on revenues from the petroleum sector, which represents over 95% of export earnings and 60% of GDP. These oil revenues and a small population have given Libya one of the highest nominal per capita GDP in Africa.
The gross domestic product (GDP) of Niger was $16.617 billion US dollars in 2023, according to official data from the World Bank. This data is based largely on internal markets, subsistence agriculture, and the export of raw commodities: foodstuffs to neighbors and raw minerals to world markets. Niger, a landlocked West African nation that straddles the Sahel, has consistently been ranked on the bottom of the Human Development Index, at 0.394 as of 2019. It has a very low per capita income, and ranks among the least developed and most heavily indebted countries in the world, despite having large raw commodities and a relatively stable government and society not currently affected by civil war or terrorism. Economic activity centers on subsistence agriculture, animal husbandry, re-export trade, and export of uranium.
The economy of Oman is mainly centered around its oil sector, with fishing and trading activities located around its coastal regions. When oil was discovered in 1964, the production and export increased significantly. The government has made plans to diversify away from oil under its privatization and Omanization policies. This has helped raise Oman's GDP per capita continuously in the past 50 years. It grew 339% in the 1960s, reaching a peak growth of 1,370% in the 1970s. Similar to the pricing of all other commodities, the price of oil is subject to significant fluctuations over time, especially those associated with the business cycle. A commodity's price will rise sharply when demand, like that for oil, outpaces supply; meanwhile, when supply outpaces demand, prices will fall.
The economy of Pakistan is categorized as a developing economy. It ranks as the 24th-largest based on GDP using purchasing power parity (PPP) and the 46th largest in terms of nominal GDP. With a population of 241.5 million people as of 2023, Pakistan's position at per capita income ranks 161st by GDP (nominal) and 138th by GDP (PPP) according to the International Monetary Fund (IMF).
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 Yemen has significantly weakened since the breakout of the Yemeni Civil War and the humanitarian crisis, which has caused instability, escalating hostilities, and flooding in the region. At the time of unification, South Yemen and North Yemen had vastly different but equally struggling underdeveloped economic systems. Since unification, the economy has been forced to sustain the consequences of Yemen's support for Iraq during the 1990–91 Persian Gulf War: Saudi Arabia expelled almost 1 million Yemeni workers, and both Saudi Arabia and Kuwait significantly reduced economic aid to Yemen. The 1994 civil war further drained Yemen's economy. As a consequence, Yemen has relied heavily on aid from multilateral agencies to sustain its economy for the past 24 years. In return, it has pledged to implement significant economic reforms. In 1997 the International Monetary Fund (IMF) approved two programs to increase Yemen's credit significantly: the enhanced structural adjustment facility and the extended funding facility (EFF). In the ensuing years, Yemen's government attempted to implement recommended reforms: reducing the civil service payroll, eliminating diesel and other subsidies, lowering defense spending, introducing a general sales tax, and privatizing state-run industries. However, limited progress led the IMF to suspend funding between 1999 and 2001.
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 economy of Bahrain is heavily dependent upon oil and gas. The Bahraini Dinar is the second-highest-valued currency unit in the world. Since the late 20th century, Bahrain has heavily invested in the banking and tourism sectors. The country's capital, Manama is home to many large financial structures. Bahrain's finance industry is very successful. In 2008, Bahrain was named the world's fastest growing financial center by the City of London's Global Financial Centres Index. Bahrain's banking and financial services sector, particularly Islamic banking, have benefited from the regional boom driven by demand for oil. Petroleum is Bahrain's most exported product, accounting for 60% of export receipts, 70% of government revenues, and 11% of GDP. Aluminium is the second most exported product, followed by finance and construction materials.
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 South Pars/North Dome field is a natural-gas condensate field located in the Persian Gulf. It is by far the world's largest natural gas field, with ownership of the field shared between Iran and Qatar. According to the International Energy Agency (IEA), the field holds an estimated 1,800 trillion cubic feet of in-situ natural gas and some 50 billion barrels of natural gas condensates. On the list of natural gas fields it has almost as much recoverable reserves as all the other fields combined. It has significant geostrategic influence.
QatarEnergy, formerly Qatar Petroleum (QP), is a state owned petroleum company of Qatar. The company operates all oil and gas activities in Qatar, including exploration, production, refining, transport, and storage. The President & CEO is Saad Sherida al-Kaabi, Minister of State for Energy Affairs. The company's operations are directly linked with state planning agencies, regulatory authorities, and policy making bodies. Together, revenues from oil and natural gas amount to 60% of the country's GDP. As of 2018 it was the third largest oil company in the world by oil and gas reserves. In 2022, the company had total revenues of US$52bn, a net income of US42.4bn, and total assets of US$162bn. In 2021, QatarEnergy was the fifth largest gas company in the world.
The economy of Ivory Coast is stable and currently growing, in the aftermath of political instability in recent decades. The Ivory Coast's economy is largely market-based and depends heavily on the agricultural sector. Almost 70% of the Ivorian people are engaged in some form of agricultural activity. The economy grew 82% in the 1960s, reaching a peak growth of 360% in the 1970s, but this proved unsustainable and it shrank by 28% in the 1980s and a further 22% in the 1990s. This decline, coupled with high population growth, resulted in a steady fall in living standards. The gross national product per capita, now rising again, was about US$727 in 1996. It was substantially higher two decades before. Real GDP growth is expected to average 6.5% in 2024–25.
The economy of Algeria deals with Algeria's current and structural economic situation. Since independence in 1962, Algeria has launched major economic projects to build up a dense industrial base. However, despite these major achievements, the Algerian economy has gone through various stages of turbulence.
The natural gas in Qatar covers a large portion of the world supply of natural gas. According to the Oil & Gas Journal, as of January 1, 2011, reserves of natural gas in Qatar were measured at approximately 896 trillion cubic feet ; this measurement means that the state contains 14% of all known natural-gas reserves, as the world's third-largest reserves, behind Russia and Iran. The majority of Qatar's natural gas is located in the massive offshore North Field, which spans an area roughly equivalent to Qatar itself. A part of the world's largest non-associated, natural-gas field, the North Field, is a geological extension of Iran's South Pars / North Dome Gas-Condensate field, which holds an additional 450 trillion cubic feet of recoverable natural-gas reserves.
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.
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.
