speculating on food / wheat , creating an artificial "demand shock" - multiplying artificially by tenfold the price of wheat :
financial engineering tricks ? - example as I understand it ? :
using the ( artificially bloating ? ) markets ( such as food markets ) to attract cash from investors,
then leverage twenty fold,
then invest excess in treasuries,
then leverage the secure treasuries again,
then dispose the credit for their traders to speculate... ( and artificially increase prices of core necessities ? ... attract more cash to use from investor clients... and leverage again ? )
