Sierra Leone has enormous potential for attracting foreign direct investment. Pre-conflict levels when inflows exceeded $100 million (1986), and although improved economic conditions since the civil war ended in January 2002, along with greater political stability and a more forward-looking government policy, have led to some new foreign investment, level s are still well below their potential based on unmet local demand, access to markets, and availability of opportunities.

During 2000–05, FDI averaged only $18 million a year, reaching the highest level in 2007 at $81 million.

Most post-conflict FDI has gone to the extractive industry and telecommunications; however, increasingly, investors are focusing on other sectors, for example, are exploring opportunities in agribusiness, manufacturing and tourism.
