Sovereign Wealth Funds could potentially help the financial system but they will only do so if it is in the national interest of their country to do so. It is this political dimension that is the reason for more regulation. Moreover regulation of SWFs will not prevent these funds from helping the global financial system. They will still be free to invest. Moreover it does not reduce the incentives for them to do so either, regulation will make no difference to a state’s motivations in a time of crisis – the national interest will remain key.
