Unfortunately, there is no change for existing home loan customers. They are cheated by banks and have to continue to pay the burden. Private sector banks like ICICI are the front runner in cheating people and Govt. is giving a blind eye to them.

The meaning of floating interest it self says that it vary from time to time according to market situation. If any bank gives loan to new customer at lower rate and dose not reduce it for old customer, they are cheating with old customer, the new customer shuld also think about honeast of such banks because later on they will also become old customer.
