What is the Big Society fund?
4 April 2012 Last updated at 10:26 BST
Big Society Capital is a new scheme that will focus on community groups and local businesses.
It has been launched by the government and will be funded by the money left unclaimed in dormant bank accounts.
Barclays, Lloyds, HSBC and RBS will provide another £50m each - as they all signed up to lend more money to firms as part of Project Merlin.
All this cash will be used to give to loans to social enterprises.
Sir Ronald Cohen, chairman of Big Society Capital told BBC Breakfast how the scheme will work.
