Structural adjustment policy packages in sub- Saharan Africa lay heavy emphasis on rolling back state regulations controlling finance and investment.

Multi-country studies by the School of Oriental and African Studies, London, looked into savings-investment performance in Ghana, Malawi, Nigeria and Tanzania. Poor results in all four cases could (suggests the study report) stem from lack of interplay between the flow of information and funds in the formal banking system and informal financial markets.
