It entirely depends on Draghi IMO. Bernanke basically said he isn't ruling anything out, that's all.
I believe the simple fact that we're in a deleveraging phase by nature makes interest rate manipulation less effective, especially in lowering rates. Manipulating interest rates lower being the previous method in credit expansion based growth, I would say that wealth would be created in a deleveraging phase by increasing interest rates.
Risk/reward analysis for debt obviously leans towards higher profit margined lending activities being based on higher levels of interest. Banks are over saturated with money right now, it would be more risky to take on loans at a potential lower profit margin, especially at scale. If banks have a higher potential margin of profit this also allows for a higher potential margin of error, and vice versa.
Interest rates being any lower isn't going to change the dynamic of this current enviornment, coupled with the fact that individuals are saving and renting more, corporations are financing themselves with bonds at record low interest rates. Buying more Treasuries or even mortgage bonds won't change anything. Stirring water around in the same bucket won't get you a bigger bucket.
Ben is going to sit tight and see how the Euro-situation plays out, if the EU can come up with solid plans, Ben will sit tight for the time being.
My two cents at least.
