So says Felix Zulauf, here:
[T]he banks, particularly at the periphery, are refunding themselves via the U.S. money market that is extremely liquid, and half of the money in the U.S. money market funds is really money to fund the peripheral European banks. Once those money market funds get hit by redemptions because investors find out, then you have a funding crisis of major scale at the periphery of Europe, and that is the next step. It is a never-ending drama until it breaks in a big way.
