The ICC T20I Rankings, also known as the ICC T20I Championship is a ranking system devised by the International Cricket Council (ICC) to rank every T20 international team according to a mathematical algorithm. Only those teams are awarded a place in the ranking system who have played a minimum of eight T20Is between 1st August of three and four years ago.
In the system, the total of each team’s points is divided by the total number of matches played by the team to give a rating.
Pakistan currently holds the top spot in the ICC T20I ratings. They overtook New Zealand in January 2018 when they beat the Kiwis in their backyard in a three-match T20I series 2-1. Pakistan followed it by whitewashing West Indies 3-0 at their home. Earlier in October 2017, Pakistan beat Sri Lanka 3-0 in a three-match series.
Australia find themselves in second place after they won the T20I tri-series held in New Zealand and Australia. Australia were unbeaten in the entire tournament and beat higher ranked teams of New Zealand and England to achieve five wins out of five matches in the tournament and move to second spot.
India, having won the T20I home series against Sri Lanka and the away series against South Africa find themselves at third.
