The rankings, announced on Thursday, are of great importance as the top seven sides in the world, plus hosts England, will compete at the 2017 Champions Trophy and the cut-off date for qualification is September 30, 2015.
Mashrafe Mortaza has said that moving up the rankings was a priority for Bangladesh to make sure they remained in contention to quality directly into the World Cup and the Champions Trophy.
Meanwhile, Australia have tightened their grip at the top of the ICC ODI rankings following their World Cup victory last month. Their lead has doubled over India after triumphing in Melbourne to lift a fifth title.
West Indies, who are ranked seventh, currently have no ODIs scheduled between now and September 30, leaving them potentially vulnerable to Pakistan, who have eight matches to come – three each at home against India and South Africa, and Bangladesh – three at home to Zimbabwe and five in Sri Lanka.
New Zealand's run to the final of the World Cup sees them rise to third in the table, while England's miserable tournament has sunk them to sixth place.
India remain in second place, the position they also occupy in the T20 rankings, with Sri Lanka, the reigning World T20 champions, extending their lead.
The latest ICC rankings see the table recalibrated to include matches only in the last three years. One-day rankings differ to the Test placing, that are calculated after every match.
