The pledge savings account is a facility that provides you with the security you need for a loan, whenever there is an emergency or something unexpected comes up there is no need to take the money out of your savings account. Use the money in your savings account as collateral on a loan. As the loan balance reduces during repayment, the pledged amount in savings reduces as well. You also continue to earn interest on any amount of the Savings pledge as collateral on the loan as usual.
