India gained seven ratings points after remaining unbeaten in their group engagements in Bangladesh to finish on 130, bringing them on par with Sri Lanka.
But when ratings were calculated beyond the decimal point, Mahendra Singh Dhoni's side found itself ranked higher.
With both India and Sri Lanka through to the semi-finals, both have a chance to either retain or reclaim the number-one position.
In the other change in the table, West Indies and Australia have swapped positions. West Indies are now ranked fifth with a gain of five ratings points and are now on 115. Australia, on the other hand, have moved down a place to sixth with a drop of five ratings points to end on 110.
In all, 13 of 16 teams ranked on the rankings table have featured in the tournament.

West Indies' leg-spinner Samuel Badree has moved up a place to replace teammate Sunil Narine as the number-one ranked bowler in the latest Reliance ICC Player Ranking for T20I bowlers.
