Dear Sir,
With respect to your quarry please find below answer :
1. I have my doubt on such transfer as it is not possible for axis bank to transfer ppf once open with them to again transfer back to sbi still need to check with bankers.
2. There will be interest loss for the period from which pay order prepared and not credited by another bank as for such time you will not receive interest on the amount invested.
For further details please free to contact me.
Thanks & Regards
