India had started the series at the third position on 113 ratings points and has finished on 117 ratings points - two ratings points clear of South Africa, which is involved in a five-ODI series against Australia.
In contrast, Sri Lanka have retained their fourth position but slipped to 108 ratings after conceding three ratings points. It now hosts England in a seven-ODI series, leading Alastair Cook's side by one ratings point.
However, with the Australia-South Africa series locked at one-all, both sides have an opportunity to regain the No 1 ranking.
South Africa will end on 118 ratings points and Australia on 111 ratings points if the series result is reversed.
