As we have been warning for nearly a year, the biggest threat facing China has been the fact that contrary to solemn promises, the problem of persistent, strong and very much relentless real-estate inflation has not only not been tamed but has been first and foremost on the minds of both the PBOC and the local government. After all with the entire "developed" world flooding the market every single day with countless billions in new cheap, hot money, it was inevitable that much of it would end up in the mainland Chinese real estate market. And since both the central bank and the politburo are well aware that the path from property inflation to broad price hikes, including the all critical to social stability pork and other food, is very short, it was inevitable that the issue of inflation would have to be dealt with eventually. Tonight is that "eventually", when following news from two days ago that yet another Chinese PMI indicator missed, this time the Services data which slid from 56.2 to 54.5, the government announced its most aggressive round of property curbs yet. The immediate result was that the Shanghai Stock Exchange Property Index slumped by a whopping 9.3%, the steepest drop since June 2008, and pushing it down to -11% for the year. The weakness also spread to the broader market, with the Composite closing down 3.65% the biggest drop in months, and now just barely positive, at +0.2%, year to date. We expect all 2013 gains to be promptly wiped out when tonight's risk off session resumes in earnest.
