John Carney from CNBC and Felix Salmon from Reuters discuss this week's news on Wall Street and beyond.

If Greece doesn't get a deal:

John Carney: So Greece has, on March 20th, a tremendous amount of debt that's coming due. They do not have the money to pay it off. This will be a gigantic default that would put several European banks in trouble, and we would have an enormous international financial calamity.

Felix Salmon: I don't think it would be that bad, to be honest. Well, it is a default, there's no two ways about it. If you don't pay back $14 billion when it's due, that's a default. The only question is: Will you replace that amount that you owed with something else and keep on paying that, or will you just owe that $14 billion and have that paper be in default?
