It's the ECB stupid!

So the Fed announced yesterday that they will inject money into European banks if needed. Mark Thoma and Paul Krugman posted about it (here and here). This is not new, since the Fed did lend to European banks after the Lehman collapse. The reason is simple, US banks would be also affected by a collapse of the European banking sector. The point is that this not sufficient to end the euro crisis, for that the ECB must act buying European bonds. No substitute for that. So Bernanke is still asking: what are these guys doing over there?
