As we’ve discussed previously, this weekend’s meetings of the G7 and the IMF are crucial to halting the financial crisis. This weekend, we’ll be updating you on events as they happen.

Update (Friday evening): The G7 statement is pretty much a general set of principles with which it would be hard to disagree, with very little by way of specifics and really nothing that we hadn’t seen before.  Mr. Paulson’s statement today was similarly vague, although Treasury continues to signal that it will launch some sort of recapitalization program.  I know they want to exude calm and confidence, but the sense of urgency that had building in the last couple of days seems to be slipping away from them.

Update (Saturday morning): Reaction from around the world is mostly disbelief.  Could it really be the case that the G7 does not understand that trade credit is under pressure everywhere, that financing for new projects is drying up, and that Iceland’s experience sends a dangerous signal to investors?  Our piece in the Washington Post Outlook section lays out the very real dangers.  Unless the G7, separately and jointly, act more decisively by the end of Sunday (yes, tomorrow), I’m afraid that next week could be quite difficult.

Update (Sunday morning): Reliable sources indicate that the eurozone member countries, who are due to meet today at the invitation of President Sarkozy, may well be able to announce agreement on some sort of parallel bank recapitalization scheme(s).  It is also hard to imagine that the US will let the day go by without a major announcement.  But it will take a great deal of detail in order to be credible at this point.  And the question of who is and is not given a place on the Great Ark for Bankers will be much on our minds.
