On 26 October 2021, the ITTF announced the Women's Singles World Rankings for Week 43 of October. Since there have been no major events in the ITTF recently, the world's top players are basically in the rest period, so there is no change in the top ten players in the world ranking. Chen Meng and Sun Yingsha continued to maintain the top two, and Japan's Ito Mimachi ranked third.

However, the rankings of Ding Ning, Zhu Yuling and Liu Shiwen, who are in the top ten in the world, are likely to change a lot next month. Ding Ning has announced his retirement and will not participate in any international competitions. Therefore, Ding Ning's world ranking will gradually fall out of the top ten over time until it disappears into the world women's singles ranking list. Zhu Yuling cannot participate in the short term because she is recuperating from illness, and what position she can fall to in the future world ranking depends on whether she can come back in time. Liu Shiwen voluntarily withdrew from the Houston World Table Tennis Championships this time, and it is normal for her world ranking to decline next month, after all, she is missing more than 2,000 points for a World Table Tennis Women's Singles Champion. However, as long as Liu Shiwen can participate in the next WTT events, it is still easy to remain in the top ten in the world.

Wang Yidi and Liu Weishan will compete in WTT Slovenia on November 4. If Wang Yidi can win the women's singles championship, she is likely to surpass Singapore's Feng Tianwei to enter the top ten of the world women's singles. And Wang Yidi will also participate in the next Houston World Table Tennis Championships, once a good result is achieved, it is also very likely to enter the top five of the world women's singles.
