If you cant wait for more than a year, Uday Narayan Dubey, institutional business head of R K Global's suggests to look at long-term(3 year) fixed maturity plans(FMPs, one-year returns = 8.21%), which can be redeemed withing six months.The yeilds will also be high on the back of high interest rates. The exit charges are a minimal, so even if you exit before the tenure is over, you will take a big hit.

                                   It is advisable to lock in your money in instruments which help you take advantage of high interest rates. Fixed deposits should be considered only if you are sure of the holding period because exiting it will come at a price.
