Weakness in commodities "is not transitory," Art Cashin tells CNBC, if you look at things like copper, "this is really a deflationary push... where things can get a little out of control."

The long-run consequences of policy during the past few years could easily mean lower long-run potential growth and inflation. Today’s consumption and market speculation was paid for with huge amounts of accumulated debt. Tomorrow’s revenues will have to be steered toward servicing that debt.
