Africa's Lost Billions

Over the last 50 years, African countries have lost about $1 trillion to illicit financial flows. This equates to around $50 billion a year and is equivalent to all the official development assistance received by the continent over the same period. It is enough to wipe out Africa’s total external debt of around $250 billion and still leave $600 billion for poverty alleviation and economic growth.
