24/7 Wall St. reviewed publicly available annual compensation figures for the 20 highest-paid leaders in the world. Salaries are expressed in U.S. dollars that were converted from country of origin currencies as of April 13, 2018. Leaders of absolute monarchies such as Qatar, Brunei Darussalam, and Saudi Arabia were excluded from our list. Constitutional monarchies were included, except where the highest ranking officials have the power to appoint the government. In such cases, including Kuwait, Bahrain, and United Arab Emirates, state leadership compensation often is not publicly disclosed. The head of state is by definition the highest ranking official in a sovereign nation. However, in cases where the head of government is paid a higher salary, she or he was listed instead. The identities and dates of election or appointment of these leaders were obtained from the CIA World Factbook, national government websites, and media sources.
