Wales have slipped two places to sixth in the latest International Rugby Board rankings following their 3-0 series defeat in Australia.
Both England - following their 14-14 draw in South Africa - and France have gone above Wales.
But the margins between fourth and sixth are tiny with just 0.83 of a point separating the three sides.
Rankings are crucial for the 2015 World Cup draw with the top four seeded and avoiding each other in the Pool stage.
As things stand, New Zealand lead the rankings, Australia are in second, South Africa third and England fourth meaning all four will be in separate pools.
Wales will not get a change to improve their ranking until the autumn internationals in Cardiff when they play Argentina (10 November), Samoa (16 November), New Zealand (24 November) and Australia (1 December).
Despite losing 60-0 to the All Blacks, Ireland move up to seventh with Argentina falling to eighth after their defeat to France.
Scotland's victorious tour to the southern hemisphere sees them move up to ninth with Samoa falling to tenth. Italy rise to 11th with Tonga falling to 12th.
