But with wealthy Chinese buyers suddenly out of the real-estate market, housing analysts are anticipating a wave of sharp declines in housing prices in some of the world's most expensive markets like New York City, London and Hong Kong.

But during the first half of the year, real-estate prices in these markets have continued to climb. Even in Hong Kong, one of the most expensive markets, and also one of the first places one might expect the impact of a mainland pullback to be felt, prices have instead climbed to all-time highs, according to Bloomberg.  

The Centaline Property's Centa-City Leading Index of existing home prices surged to a record high 160.3 as of July 30. The index has climbed 11 percent this year, and more than 50% in the past five years.
