Overlending in Andhra Pradesh calls to mind the U.S. subprime crisis, says Lakshmi Shyam-Sunder, director of corporate risk at International Finance Corp. in Washington, which invests in microlenders. “Subprime lending was initially seen as extending homeownership to poorer people, doing good,” Shyam-Sunder says. As the industry expanded, making a profit became more important to some lenders, she says.
