What is new here is that you cant really see it because all major currencies are increasing their supply at similar rates.
So stocks, houses and apples increase in value rapidly as more money exists than there are things to buy, but the relative inflation of any economic union is completely masked.
Therefore the classic concern - speculators loosing confidence in the currency - isn't quite a classic concern.
They don't have an alternative as all major currencies are doing the same thing. To play that script they would need to be exiting fiat currencies, so watch for that.
But the macro trend is worldwide speculators pounding against the dam for negative interest rates in the US. Thats the season finale for now and cliffhanger, with no real prediction on the next season’s contents.
