Understanding the difficulties associated with supervising and regulating microfinance institutions may lead central banks (or the appropriate bank regulatory body) to rethink their supervisory approach as a whole. For example, the growth and commercialization of microfinance might put pressure on governments to remove interest rate controls and directed lending to cronies. Similarly, a focus on microfinance might force regulators to move away from rigid capital adequacy and more toward risk-based supervision of internal systems for information gathering, monitoring, and risk control. Unfortunately, many supervisors in the developing world will not have the capacity to do this well, even for mainstream banks, let alone microfinance institutions.
