Churn, Baby, Churn - The China Commodity Bubble Exposed In 1 Simple Chart

The frenzied trading that smashed Chinese commodity markets through the roof in the last month has begun to unfurl rapidly as authorities crackdown on the speculative fever and force exchanges to curve excess 'churn'. Of course, there are still some who cling to the belief that any of this was 'real' demand, real buying, and real economic growth (just don't look at The Baltic Dry in the last few days) but, as Bloomberg reports, it was nothing but "churn baby churn" as trading volume exploded but open-interest remained flat.
