AAA debt is dangerously common

"The amount of debt in the world is soaring.
The amount of triple-A debt in the world is soaring as well. 
Which is a worse thing, because triple-A debt is much more systemically dangerous than most other debt.

Global issuance of triple-A bonds was more or less nonexistent back in the early 90s. 
For the past decade it has invariably accounted for somewhere between 50% and 60% of total global fixed income issuance. That’s possibly the most horrifying bit of all: it simply defies credulity for anybody to be asked to believe that more than half the bonds issued in any given year are essentially free of any credit risk."
