Acceleration in the decline in copper is not good.
Negative interest rates on bank deposits isn’t good news either.
Even with the printing presses running at full speed, and very minimal interest rates on money put out at interest, the world is suffering from a spate of DEFLATION, too few dollars chasing too many goods and services, goods and services which are just piling up in inventory at businesses which must soon either discount heavily, or close their doors. Even if they do close their doors, and the inventory is sold at a vast discount, it remains unsold to the ultimate consumer because of not just stagnant demand, but no demand at all.
The velocity of transfers of money has fallen a good deal, the pie is SHRINKING.
