This front page New York Times article delves into the current conversation within the microfinance sector about the balance between social impact and financial returns.

From original article

[Microfinance] has grown so popular that some of its biggest proponents are now wringing their hands over the direction it has taken. Drawn by the prospect of hefty profits from even the smallest of loans, a raft of banks and financial institutions now dominate the field, with some charging interest rates of 100 percent or more.

"We created microcredit to fight the loan sharks; we didn't create microcredit to encourage new loan sharks," Mr. [Muhammad] Yunus recently said at a gathering of financial officials at the United Nations. "Microcredit should be seen as an opportunity to help people get out of poverty in a business way, but not as an opportunity to make money out of poor people."

The fracas over preserving the field's saintly aura centers on the question of how much interest and profit is acceptable, and what constitutes exploitation. The noisy interest rate fight has even attracted Congressional scrutiny, with the House Financial Services Committee holding hearings this year focused in part on whether some microcredit institutions are scamming the poor.

Underlying the issue is a fierce debate over whether microloans actually lift people out of poverty, as their promoters so often claim. The recent conclusion of some researchers is that not every poor person is an entrepreneur waiting to be discovered, but that the loans do help cushion some of the worst blows of poverty.

"The lesson is simply that it didn't save the world," Dean S. Karlan, a professor of economics at Yale University, said about microlending. "It is not the single transformative tool that proponents have been selling it as, but there are positive benefits."
