The stellar growth of sovereign wealth funds in recent years is set to continue, according to the latest research from a City of London think-tank. International Financial Services London estimates that assets under management will rise to $5,000bn by 2010 and $10,000bn by 2015.

Much of the attention has focused on the $3,300bn of assets managed by the highest profile funds, but there is almost double that amount in other government-controlled investment vehicles that are also growing fast.
