Abstract: Banking business has done wonders for the world economy. The simple looking method of accepting money deposits from savers and then lending the same money to borrowers, banking activity encourages the flow of money to productive use and investments. This in turn allows the economy to grow. In the absence of banking business, savings would sit idle in our homes, the entrepreneurs would not be in a position to raise the money, ordinary people dreaming for a new car or house would not be able to purchase cars or houses. The government of India started the cooperative movement of India in 1904. Then the government therefore decided to develop the cooperatives as the institutional agency to tackle the problem of usury and rural indebtedness, which has become a curse for population. In such a situation cooperative banks operate as a balancing centre. At present there are several cooperative banks which are performing multipurpose functions of financial, administrative, supervisory and development in nature of expansion and development of cooperative credit system. In brief, the cooperative banks have to act as a friend, philosopher and guide to entire cooperative structure. The study is based on some successful co-op banks in Delhi (India). The study of the bank’s performance along with the lending practices provided to the customers is herewith undertaken. The customer has taken more than one type of loan from the banks. Moreover they suggested that the bank should adopt the latest technology of the banking like ATMs, internet / online banking, credit cards etc. so as to bring the bank at par with the private sector banks.
