When defining the world’s richest countries, most people tend to use Gross Domestic Product (GDP) as the primary indicator. However, most economists today prefer to use the metric of purchasing power parity (PPP).
While government economists may play with numbers for various vested interests, PPP provides a very intuitive reflection of actual purchasing power by calculating a currency’s equivalent value based on the price levels of basic goods and services in different countries.
Therefore, this article uses GDP per capita calculated by PPP to identify the top five richest countries in the world. These five are all relatively small nations, and in fact, smaller countries tend to be more favored by global investors. This might come as a surprise if you’re not familiar with PPP. Although small in size, these highly developed nations have a significant impact on the global economy. Furthermore, their residents generally enjoy a high standard of living.
Below is a detailed introduction to these five countries. While many hold the stereotype that Europe is more developed, this list also includes Asian countries. They are:
- Brunei
- Kuwait
- Singapore
- Luxembourg
- Qatar

The World’s Five Richest Countries
Brunei
Brunei’s oil wealth places it as the fifth richest country in the world, with a per capita GDP of over $71,000.
Located in Southeast Asia, Brunei is a small country whose economy is sustained by oil revenues. Its citizens enjoy free education, government-subsidized housing, and are exempt from common taxes found in other countries, such as personal income tax, sales tax, and value-added tax.
However, due to the persistent decline in international oil prices in recent years, it is uncertain whether Brunei can maintain its current PPP level. The oil and gas industry accounts for over 95% of Brunei’s exports. Under this single-commodity economic model, Brunei experienced a severe government fiscal deficit between 2015 and 2016.
In recent years, the Brunei government has gradually intensified its economic diversification strategy to move away from its over-reliance on oil and gas. After years of effort, while its economic structure is still dominated by oil and gas revenues, it is slowly transitioning from a traditional single-commodity economy to a diversified one, comprising industries such as fisheries, agriculture, transportation, tourism, and financial services, with some positive results. Additionally, Brunei has been strengthening its economic ties with China and plans to establish a stock exchange in the coming years.
To attract more foreign investment, Brunei’s current Minister of Energy and Industry is committed to improving the country’s business ranking. According to the latest data from the World Bank, Brunei’s ease of doing business ranks 66th out of 190 countries and regions, which indicates significant room for improvement for a wealthy nation.
Kuwait
Kuwait is the fourth richest country in the world, but its efforts to diversify its economy beyond oil have been relatively limited.
Kuwait’s proven crude oil reserves account for 10% of the global total, ranking fourth in the world. Oil is the main source of Kuwait’s fiscal revenue and the backbone of its national economy, with its output value constituting about half of Kuwait’s GDP. Unlike Brunei, Kuwait’s deployment in economic diversification is much smaller, and its domestic economy is extremely dependent on the oil industry. According to data from the Kuwaiti Ministry of Finance, oil revenues accounted for as much as 93% of total fiscal revenue in the 2022-2023 fiscal year.
Similarly affected by the decline in international oil prices, although Kuwait is currently the fourth richest country in the world, its prospects are not bright without strengthening economic diversification.
Besides the oil dilemma, Kuwait’s internal political tensions have also had a certain impact on its economy. Although considered the most democratic of the Gulf autocratic states, Kuwait has long been plagued by political struggles between the elected parliament and the government controlled by the Emir. This political stalemate has limited the country’s ability to implement economic reforms to move away from its dependence on oil exports. While the Middle East is a new hotspot for global investment, it is best to exercise a degree of caution when investing in a country with tense political and economic situations.
Singapore
The city-state of Singapore is the third richest country in the world and a typical example of a small but extremely wealthy nation, with a per capita GDP of over $82,000. At the same time, Singapore’s cost of living is among the highest globally.
Overall, it is not without reason that Singapore has become a global investment hotspot and a renowned offshore tax haven, one of which is its very favorable tax policies.
Furthermore, Singapore’s economy is highly developed. Rated by the World Bank as the easiest place to do business globally, it is recognized as the world’s most open and least corrupt market. Singapore has always been committed to collaborating with businesses to provide solutions to the world’s most pressing problems and has been named one of the most innovative cities in the world for several consecutive years.
Luxembourg
Luxembourg is a small European country whose wealth comes from diversified industries such as banking, steel, telecommunications, and tourism. With a per capita GDP of over $97,000, Luxembourg is the second richest country in the world.
Luxembourg has a population of only 500,000 but hosts over 9,000 holding companies. The headquarters of the world’s largest multilateral lending institution, the European Investment Bank, is also located in Luxembourg. Luxembourg offers the lowest corporate income tax rate in all of Europe, at 17%. Over the years, many companies have flocked to Luxembourg to take advantage of its low tax policies while passing on the benefits to their customers.
Qatar
Qatar is a monarchical Arab state on the coast of the Persian Gulf. Although a small peninsula nation, according to the International Monetary Fund, Qatar is the richest country in the world. Qatar is known for its multicultural society, attracting residents from over 180 countries worldwide.
Qatar has excelled in Asian football, and the 2022 Qatar World Cup was hailed by the FIFA President as the best ever. To prepare for the World Cup, Qatar spent approximately $220 billion on domestic infrastructure projects, including roads, cities, public transportation, hotels, sports facilities, and stadiums. As the first Arab country to bid for the World Cup, Qatar significantly enhanced its international reputation by hosting the event.
Moving to the Wealthiest Countries in the World
Is moving to one of these countries a wise choice? Our advice is to first gain a deeper understanding of the local culture, lifestyle, and work environment by starting a business, working as an employee, or simply living there for a period before making a final decision. For expatriates or young professionals just starting their careers, living in a country that has achieved great success in the globalized economy can help open up new perspectives and provide broader development opportunities.
Additionally, the income levels in these countries are among the highest in the world, which means you may enjoy a relatively high standard of living. However, high income is also accompanied by high prices and a high cost of living, which is one of the factors to consider. When making your decision, you need to weigh multiple factors such as personal career development, quality of life, and financial situation.
In conclusion, moving to one of the above countries can be a challenging yet opportunity-filled decision. Before making the final choice, gaining practical experience and a thorough understanding of the target country can help lay a solid foundation for your future life and career planning.
