Neat summary of the problem with the 'risk-free' asset class via ECR:
Excluding Germany and the US - both with Negative or Stable/Negative outlook, there isn't much of liquid AAA-rated bonds out there... And Canada and Australia are the only somewhat liquid issuers with Stable AAA ratings (for now). Which, of course, means we are in a zero-beta CAPM territory, implying indeterminate market equilibrium and strong propensity to shift market portfolio on foot of behavioural triggers... ouchy...
