We have seen interest rates offered by tax free bonds have gone up these days. Now we have Hudco tranche II offering 9.01% for retail category for 20 yrs and NHPC giving 8.91% for the same.

Is it like the interest rates are peaking and we should bag the deal or we can wait and more issues with similar/higher interest rates can be expected?

If they are very lucrative deal, then can these tax free bonds become a major part of one’s debt portfolio assuming one doesn’t need money for 10-20 years?
