Why Banks Insist on Changing Loan Tenure instead of EMI?

Every time the RBI cuts interest rates, you are made to believe that your EMI will come down. But this is not always the case. Lenders prefer to shorten the tenure than change the EMI. The reason is convenience. This saves them the hassles of readjusting the EMI, changing the ECS mandate and accepting new postdated cheques (PDCs).
