What Is a Tiger Economy?
A tiger economy is a term used to describe several booming economies in Southeast Asia. The Asian tiger economies typically include Singapore, Hong Kong, South Korea, and Taiwan.

 

The Asian tigers are high-growth economies that have transitioned from predominately agrarian societies of the 1960s to industrialized nations. The economic growth in each of the countries is usually export-led but with sophisticated financial and trading markets. Singapore and Hong Kong, for example, are home to two of the major financial markets in the world. Sometimes China is mentioned as an Asian tiger but has separated itself from the pack to become one of the largest economies of the world.
The Asian cub economies, which have developed more slowly than the tigers but have experienced rapid growth over the last several years, include Indonesia, Malaysia, Thailand, Vietnam, and the Philippines.
