Despite the slip, Nigeria remain the best team in Africa followed by Ghana (46), Cameroon (48), Equatorial Guinea (53) and South Africa (54) to complete the top five.
While Mozambique, Malawi, Lesotho, Swaziland made a return to the ranking after ending years of inactivity with the 2017 Cosafa Women's Cup.
The first Fifa ranking in 2018 will be published on Friday, March 23, 2018.
