What will say is that Pimco the largest private holder of US bonds stated a few weeks back that he sold out of all his bond holdings.
Japan with the second largest holding of US bonds needs Money to rebuild. Will they dump their bonds to fund this, who knows. Who will be the buyer. The Fed most likely.
Also with the recent distortion of attention to the nuclear catastrope the real news lies with congress increasing the US debt limit.
This is the catastrophe to unfold if congress don't play ball.
In my view as terrible as japan news is the mass focus is to deflect on the issue above which will wipe the USA out.
Naturally it will get approved and the credit binge will continue for another day.
