Chinese high-yield property bonds, a popular trade that lured investors over the past year given their attractive returns, are now fast falling out of favor.

The average yield on China property bonds has risen to 9.3 percent as of end-June, after hitting all-time lows of just under 7 percent on May 10, according to Deustche Bank, which tracks 80 U.S. dollar denominated bonds in the sector, most of which are non-investment grade. The average yield currently stands at 8.8 percent.
