Swiatek won her fifth career grand slam title at the French Open in June, though she did suffer third-round exits from the Australian Open and Wimbledon before going out in the last eight at the US Open earlier this month.
However, Swiatek still sits over 2,000 points clear of her closest rival, Flushing Meadows champion Aryna Sabalenka, at the top of the women's world rankings.
She has now spent a total of 122 weeks at the top of the rankings, moving clear of Barty, who spent 121 weeks as the world's top-ranked female player.
Only Steffi Graf (377 weeks), Martina Navratilova (332), Serena Williams (319), Chris Evert (260), Martina Hingis (209) and Monica Seles (178) have now spent more time as world number one than Swiatek since the rankings were introduced in 1975.
