Closing the small-business credit gap at average lending spreads and adding fee-based services could generate about USD 270 billion in additional revenue for banks, while including unbanked adults into the formal financial system could generate another USD 110 billion, the report by Accenture said.

"77 per cent of the 30 banks surveyed for the report were focused on short-term profit-driven commercial opportunities in a piecemeal manner, or were driven by philanthropic ambitions, the corporate social responsibility agenda or regulatory pressures," it said.
"The traditional view has been that banking the unbanked and underbanked tended to be low-end, unprofitable and philanthropic," it said.
