The West Indies team has slipped to fifth in the latest ICC Twenty20 rankings following their 2-0 defeat to New Zealand in the three-match series, which ended recently.
The reigning Twenty20 World champions began the series fourth but lost five points to stand on 115 points and are now below fourth-placed England who they beat in the final of the Twenty20 World Cup in 2016.
Since capturing the Twenty20 World Cup, the West Indies team has now lost nine of their last 17 matches, including full series against a higher-ranked nation.
Meanwhile, New Zealand has overtaken Pakistan as the top-ranked side in the format, following their series triumph.
The team gained six points to move to 126 points, now two clear of second place Pakistan, with India third on 120 points.
South Africa is sixth on 112 points, Australia lies seventh on 111 while Sri Lanka is eighth on 88 but only two points ahead of minnows Afghanistan in ninth.
