Singapore's economy has been ranked as the most open in the world, 7th least corrupt, most pro-business with low tax rates and has the third highest per-capita GDP in the world; in terms of Purchasing Power Parity (PPP). Government-linked companies play a substantial role in Singapore's economy, which are owned through the sovereign wealth fund Temasek Holdings, which holds majority stakes in several of the nation's largest companies, such as Singapore Airlines, SingTel, ST Engineering and MediaCorp. The economy of Singapore is a major Foreign Direct Investment (FDI) outflow financier in the world. Singapore has also benefited from the inward flow of FDI from global investors and institutions due to her highly attractive investment climate and a stable political environment.

Exports, particularly in electronics, chemicals, banking and finance and services including the positioning of Singapore as the regional hub for wealth management provide the main source of revenue for the economy.
