As Bloomberg's Richard Breslow details in today's note, the worst kept secret in the financial world is now not only accepted orthodoxy, but finally being discussed openly by, at least some, authorities.

Central bank policies are directly driving asset prices and the bubbles therein. It's what they do. It has been so stunningly obvious that, at this point, it makes a mockery of things to deny it as an ongoing, and essential, part of how their strategy is implemented.

And it is an undeniable factor in this January's price action.

Alan Greenspan knew it to be the case.

Ben Bernanke had no problem with it. His strategy required it.
