The recent press interest in sovereign wealth funds (SWF) seems to stem from their high profile equity investments involving Blackstone and Barclays Bank. Who are these cash rich faceless entities and what are their motives? To name names, the biggest SWFs by assets include the Abu Dhabi Investment Authority ($875bn), Temasek (the Singapore government pension fund- $100bn), the China Investment Co ($1,200bn) and the Qatar Investment Authority ($40bn). These mainly Middle and Far Eastern groups are basically trust funds that can be called on to meet pension or state liabilities in the future.
