The five-match series is currently being led by New Zealand 2-0.
If India win both the matches they will go to the top with a gain of one ratings point to end at 118, one ahead of Australia.
But if they lose even one of the two matches, India will stay in second place with a loss of one ratings points at 116, one behind Australia. Loss in both the matches will mean India drop two ratings points to finish on 115 still in second place, two behind Australia.
