Singapore

While several Asian cities have risen and fallen on the list of the world's most expensive cities throughout the years, Singapore has finally risen to the top. Singapore, officially known as the Republic of Singapore, is a sovereign city-state on an island in Southeast Asia – not exactly the conventional description of a city, but one we're willing to accept.

Singapore is one of the most expensive cities in the world for a variety of reasons, including its famed cleanliness and usage of green energy. Singapore's grocery, automobile, and transport prices are excessive, yet the food is famed around the world not just for being great but also for being shockingly inexpensive.
