The market for small business loans "should be the focus of inquiries regarding competition in lending, rather than the mortgage market," the Reserve Bank of Australia argued in its submission to the Financial System Inquiry.It said the market for small business loans "has more structural impediments to competition than most other lending markets, because the information asymmetries tend to be more significant."The RBA said technological advances and financial innovation can help to reduce these asymmetries. It cited data from the Australian Centre for Entrepreneurship Research that "new and young businesses are less likely to use bank debt than to use personal funds.  … When accessing bank funding, these firms use credit cards and personal loans rather than business loans."Trade credit from suppliers was also a business lifeline after the GFC.
