Africa's 'Idle Trillions' Are Already Hard at Work

This Brookings Institution analysis challenges the widely circulated claim that Africa has over $2 trillion in 'idle' domestic savings that can be easily redirected to close the continent's infrastructure gap. The author argues that these funds are already deployed in various forms—such as government bonds, liquidity reserves, and pension liabilities—and that redirecting them involves significant trade-offs, including fiscal austerity or increased foreign borrowing. A detailed breakdown shows that of the $4 trillion gross institutional capital pool, only about $300 billion is plausibly redirectable. The article uses Nigeria's pension funds as an example, noting that 77% of assets are in government securities, meaning the state has already borrowed that money. It concludes that forcing infrastructure investment would concentrate sovereign risk rather than diversify it, and that a one-time redeployment would only cover about 11% of one year's infrastructure gap.
