ZeroHedge has long stated that San Francisco is the canary in the American housing coalmine, and after a double round of bad housing news, that canary is looking green around the gills. To wit:

Courtesy of [San Francisco’s] location, not only does it reflect the general Fed-driven liquidity bubble which is the tide rising all housing boats across the US, but due to its proximity to both Silicon Valley and China, it also benefits from two other liquidity bubbles: that of tech, and of course, the Chinese $25 trillion financial debt monster, where since the local housing bubble has burst, local oligarchs have no choice but to dump their cash abroad.

Well, in the aftermath of yesterday's data which beyond a reasonable doubt showed that the Chinese housing bubble has burst, we can now report that the "flashing red" market that is San Francisco was just smacked by a "double whammy" perfect storm...

... which now also means that the ultra high end of US housing is now sliding fast, and that unless some other central banks steps up and resumes the injections of some $100 billion in outside money into inflating asset prices such as stocks and billionaire mansions, then all bets are soon off.
