Around $6 trillion in sovereign debt is now yielding negative, with plenty of corporate debt heading down too.

There are very few voices mentioning any risk in this bond market, it is still regarded as the flight to safety. But neg yielding govt bonds to that extent, and so far out (almost to 10yrs for some) surely isn't a sign of health.

This would fit in with Armstrong's debt crisis phase transition call ; he says a collapse in confidence in govt or some event that shocks this bond market will see a rush out of govt bonds and into the private realm of stocks. I presume this would also lead to the moonshot for gold etc as well.
