Mahendra Singh Dhoni with 793 points is ahead of Australia's Mike Hussey by 17 points.
Master blaster Sachin Tendulkar, who did not play the ODI series against Sri Lanka due to an elbow injury, also retained his eighth spot in the batting chart with 724 points.
In the bowling department, Australian pacer Nathan Bracken slipped off the top.
In three ODIs, the 30-year-old left-hand pacer took just two wickets at an average of 29 and such is the competition in rankings, that was enough to knock him off top spot. His place is taken by New Zealand captain Daniel Vettori.
Bracken's team-mate Mitchell Johnson has also slipped one place to fourth but fellow pacer Stuart Clark has jumped four places after picking up five wickets at an average of 9.20.
He shares 15th spot with the West Indies' Daren Powell and Pakistan's Iftikhar Anjum.
Australia's 3-0 victory has earned it one ratings point which has lifted it to 131 ratings points. In contrast, Bangladesh has dropped to 45 ratings points.
The ODI action resumes next month when New Zealand plays Bangladesh in a three-match ODI series in Mirpur (Oct 09 and 11) and Chittagong (Oct 14) while Ireland, Zimbabwe and Kenya feature in a tri-series in Nairobi from Oct 17-25.
