Big Banks Draw Big Profits From Microloans to Poor

In recent years, the idea of giving small loans to poor people became the darling of the development world, hailed as the long elusive formula to propel even the most destitute into better lives.
Actors like Natalie Portman and Michael Douglas lent their boldface names to the cause. Muhammad Yunus, the economist who pioneered the practice by lending small amounts to basket weavers in Bangladesh, won a Nobel Peace Prize for it in 2006. The idea even got its very own United Nations year in 2005.

But the phenomenon 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.

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.”
Still, its earliest proponents do not want its reputation tarnished by new investors seeking profits on the backs of the poor, though they recognize that the days of just earning enough to cover costs are over.
