Re Yen, as safe haven….makes no sense to me.
but I think it comes from FX mkt, where bankster traders, can only trade FX, so they label one currency, as a safe haven and label another as a dog etc…that way they will tend to be long the safe haven and short the Dog, or dogs.
Now as most desks daytrade mainly…..it has no real effect….but when asked by a CNBC/Bloomberg muppet for a comment, they say the Yen is up due to safe haven buying…..etc.
