In the past five years, the microfinance community has encouraged microfinance institutions (MFIs) to broaden the scope of product offerings for their clients beyond microcredit, especially by offering savings products. However, in the microfinance sector, quantitative analysis of depositor behavior and aggregate savings balances is still nascent. Instead of using a savings volatility analysis to determine potential withdrawals, MFIs often estimate the amount of savings that should be held in cash or liquid assets, or they simply follow guidelines from regulators, funders or global networks.
