Step 1: Understand the risk banks face:
Collateral is an asset, such as land or a building, that a borrower pledges as security. If the loan is not repaid, the bank can sell it to recover its money.
Poor women usually have no such asset. So a bank thinks that lending to them is risky, because it has no security if the loan is not repaid.
A Self-Help Group (SHG) is a small group of 15 to 20 neighbours, mostly women, who save money regularly and give small loans to each other. The group acts as a bridge between the bank and the poor woman.
Step 2: Point 1: joint responsibility for repayment:
The bank lends to the group, not just to one woman. The members share the duty of repaying.
If one member fails to pay, the group must still handle it. So the bank has the assurance of repayment even without collateral.
Step 3: Point 2: the group watches its own members:
Group members live close to each other and know how the loan is being used. They keep an eye on each member and make sure the money is used for the stated purpose.
If someone is late in paying, the group follows up and pressures her to repay. The bank does not have to chase each small borrower, which lowers its cost and its risk.
Step 4: Point 3: savings habit builds trust:
SHG members save regularly and hold regular meetings, where accounts are kept and discussed.
This shows discipline and reliability. The bank can see a record of savings and repayment inside the group, so it feels confident to lend.
Final Answer:
SHGs reduce the bank's risk because the group shares the responsibility for repayment, monitors each borrower, and shows financial discipline through regular savings and meetings. So banks can lend even without collateral.
\[ \boxed{\text{Group responsibility, monitoring of members and regular savings reduce the bank's risk}} \]
