The 24-year-old Hosszu, sixth at the last edition in Shanghai two years ago and a bronze medallist in Rome in 2009, led on all four legs and touched in a time of two minutes and 07.92 seconds.
Alicia Coutts of Australia took silver in 2:09.39, repeating her second place from 2011, and Spain's Mireia Belmonte Garcia delighted the home support with bronze in 2:09.45.
Belmonte Garcia held off Ye on the final leg, with the Chinese failing to defend her world title and finishing fourth in 2:10.48.
