The Obama administration's Small Business Jobs Act of Sept 2010 set aside $30 billion to stimulate lending to small business. Only 7% of 7700 U.S. lenders have signed up for the program so far. The deadline to sign up to participate has been extended from March 31 to May 16, 2011, by the Treasury Department. Banks have been hesitant to sign up for various reasons: banks say they see a stigma to taking these loans, and need additional staff to handle the extra paperwork. Banks say there isn't enough demand for loans from small business, or that there is enough capital already to handle larger better collateralized borrowers with the others considered too risky anyway.
