Part of the problem in the banking system is the steep increase in borrowing costs. The central bank has raised interest rates by 375 basis points since March 2010, driving up deposit rates and hurting profits.

U.S. technology bellwether Cisco ( CSCO) for the first time mentioned India as a concern on its quarterly conference call last week.
