Bangkok, known officially as Krung Thep Maha Nakhon, is the capital and largest city of Thailand. It covers 1,568.7 square kilometres and is located in the Chao Phraya River delta. As of 2025, the Bangkok Metropolitan Region has an estimated population of 11.39 million, making it one of the most populated cities in Southeast Asia.

Founded in 1782 by King Rama I, Bangkok has developed into Thailand’s economic, cultural, and political centre. It contributes significantly to the country’s GDP, generating 5.747 trillion baht (US$164 billion) in 2022. The city is a major hub for finance, manufacturing, trade, and tourism, and hosts the Stock Exchange of Thailand. It is also a leading destination for international visitors.

Bangkok faces urban challenges, including traffic congestion, flooding, and air pollution. The city has ten urban rail lines, but congestion remains a problem. Due to its low elevation, Bangkok is vulnerable to rising sea levels and land subsidence.

The city is home to key landmarks, including the Grand Palace, Wat Phra Kaew, Wat Arun, and modern districts such as Siam and Sukhumvit. It has been the centre of many political protests and changes in Thailand’s history.

Bangkok is governed as a special administrative area under the Bangkok Metropolitan Administration (BMA). Unlike Thailand’s 76 provinces, Bangkok has a directly elected Governor, who serves a four-year term and oversees city administration. The Governor works with four appointed deputies and the Bangkok Metropolitan Council, which functions as the city’s legislative body.

The BMA consists of sixteen departments, responsible for infrastructure, transportation, waste management, education, healthcare, and emergency services. Civil law enforcement falls under the Metropolitan Police Bureau, which operates separately from the BMA.

The city is divided into 50 districts (khet), each further subdivided into 180 sub-districts (khwaeng). Each district is managed by a district director, appointed by the Governor. Additionally, district councils, elected every four years, serve as advisory bodies.

As the national capital, Bangkok is home to Thailand’s Government House, Parliament, and Supreme Court. Most government ministries, foreign embassies, and major state agencies have headquarters in the city.

The Bangkok Metropolitan Region, which includes surrounding provinces, is also managed through regional cooperation. The city’s administration faces challenges such as traffic congestion, flooding, and urban planning, requiring collaboration with national agencies to implement long-term infrastructure and development policies.

Bangkok is the financial hub of Thailand as the city addresses 1/3rd of the country’s banks and the Bangkok Stock exchange. The Stock Exchange of Thailand, together with the Market for Alternative Investment, has more than 650 listed companies with a combined market capitalisation of 8.485 trillion baht ($267.64 billion). Due to the large amount of foreign representation, Thailand has for several years been a mainstay of the Southeast Asian economy and a centre of Asian business. The Globalisation and World Cities Research Network ranks Bangkok as an "Alpha" world city, and it is ranked 59th in Z/Yen's Global Financial Centres Index.

Bangkok is home to the headquarters of all of Thailand's major commercial banks and financial institutions, as well as the country's largest companies. Many multinational corporations base their regional headquarters in Bangkok due to the lower cost of labour and operations relative to other major Asian business centres. Seventeen Thai companies are listed on the Forbes 2000, all of which are based in the capital, including PTT, the only Fortune Global 500 company in Thailand.

Bangkok also ranked 2nd in Enpact’s Startups Friendliness Index 2018. Bangkok's business environment is adapting to the startup-friendly ecosystem offering adequate financial services to encourage startups development although the city still has to increase the number of incubators and accelerators.
 

Bangkok, Thailand's capital, boasts a comprehensive infrastructure network that supports its status as a major Southeast Asian metropolis. The city is served by two international airports: Suvarnabhumi Airport, which opened in 2006 and handled over 52 million passengers in 2015, surpassing its designed capacity of 45 million, and Don Mueang International Airport, which reopened for domestic flights in 2007 and resumed international services in 2012, primarily accommodating low-cost carriers.

The urban transit system includes the BTS Skytrain, MRT, and Airport Rail Link, collectively covering over 276 kilometres with 189 stations as of January 2025. These systems have become essential for daily commuters, with the BTS reporting an average of 799,436 daily trips and the MRT 474,207 daily trips in early 2025.

Despite an extensive road network, Bangkok faces challenges with traffic congestion. Efforts to alleviate this include the development of elevated expressways and ongoing expansion of public transit systems. Water transport remains vital, with services like the Chao Phraya Express Boat serving numerous stops along the river.
