Wearning a green khaddar kurta and waistcoat over a pair of brown trousers, Mohammad Yunus of Bangladesh's Grameen Bank does not appear your conventional banker. But, then, the money-lending facility that he heads as managing director is no ordinary financial institution.
The bank gives out micro-loans to the poor without demanding collateral in return. Based on mutual trust, the relationship between the bank and borrower seems to have paid off. Today, Grameen Bank, with its four million borrowers - 96 per cent are women - can boast a repayment rate of 99 per cent.
Talking to this correspondent at a dinner where he was chief guest during his recent visit to Karachi, Mr Yunus explained why the poor don't default on payment. "They pay back because they don't have enough and because this is not just one-time borrowing. They don't want to see the door shut. If she (the borrower) is not paying back, she cannot take another loan," he said.
The other reason, he observed, had to do with the requirements of the system. Borrowers belong to a group of five, and although the group does not have to pay back the amount lent to a defaulting member, it does exert pressure on the individual to return the loan.
"The group becomes a loan-sanctioning authority and decides whether a member should take the money or not. It assesses the person's ability to handle the money, taking into account factors like one's family situation and whether the borrower's husband will be opposed to it."
If the group feels that a borrower is squandering the loan given by the bank, it makes its feelings known. "It is as if it is the group's money because they approved the loan," he said.
As a general policy, the bank does not advise people on how to use the money they have borrowed. "We tell the borrower, we don't know anything, you know everything. We have money, but no ideas (for its use). That's why we come to you. You have no money but you have the ideas. So you can use your ideas and our money."
While the bank itself was established in 1983, Mr Yunus's efforts to empower the poor date to 1974 when a famine raged in a land already devastated by the ravages of war.
He saw first-hand the exploitation of the desperately poor at the hands of moneylenders who would quote a price for their ware and then go on to sell it in the market for a profit.
Making a list of 42 such people, he saw that the total amount they had borrowed was just $27. That was the beginning. What followed was months of running around trying to get banks to agree to give loans to the poor. "Everybody said it could not be done, so I finally offered myself as a guarantor so that I could take the money from the bank and give it to the poor. It worked."
Since its establishment, Grameen Bank has expanded in several different directions - creating companies for sectors as diverse as textiles, software and mobile phones.
Mr Yunus appeared especially enthusiastic about the latter. Loans are offered to women wanting to invest in mobile phones so that they can start a business by providing clients access to the outside world for a small fee.
This spirit of entrepreneurship is apparent in many of Grameen's programmes that encourage women to come forward, to move beyond the frontiers of home and tradition, and to help evolve a national psyche that recognizes their contribution to labour and development.
He had a kind word for other organizations in the field. "NGOs in Bangladesh have picked up micro-credit very well and benefit eight million families. So, together with Grameen Banks, 12 million families are receiving micro-credit."
Asked if he had plans to extend his services to the rest of South Asia, Mr Yunus answered: "We keep talking about it. It is my job to keep talking about it. If anyone is interested they can come and visit and find out how to do that. There are several organizations (extending micro-credit services) that have started in Pakistan."
The conversation ended soon because guests, comprising industrialists, journalists, diplomats and others, were getting impatient. They wanted Mr Yunus to talk to them, and soon he was lost from view as they milled round him, eager to hang onto every word uttered by the world's most famous banker to the poor.
