Somehow he got the European Central Bank to commit to quantitative easing for a change instead of having to do it again himself.
It buys Ben a bunch of time, and gives him cover during the perilous political season when direct Federal Reserve action would look especially political. Maybe it even frees him up to do a little bit more, on the theory that he can always credit any success we experience to European action, not to his, saying a rising tide lifts all boats, and rot like that.
Crafty devil.
Obama must be praying like hell it works long enough and well enough to keep everyone afloat for three more months.
