HDFC Bank has this facility to create  a certain type of Fixed Deposit that protects you against your cheques being dishonoured. If you have this type of FD, funds will automatically be “swept-in” into the savings account from the FD whenever needed. The balance of the FD will continue to earn the original rate of interest, while the amount that was swept in will be treated as if it was in a savings account. In ICICI Bank, there is a facility where if you have excess money in your savings account, it will be automatically swept out and be made an FD. HDFC, however, makes it as difficult as possible to create this type of FD.  You can create normal FDs through netbanking, but not ones with the sweep-in facility. For this, you have to visit the branch or call up their phone banking. Rather interesting way to “match” ICICI’s offering without increasing your cost of funds.
