The Greek crisis just got another dimension: in a dramatic speech, Greek PM Alexis Tsipras announced a referendum on the latest EU proposals which he just rejected. It will be held on July 5th, after the June 30th deadline.

There are less than 48 hours until markets open, and if nothing changes, it is going to be very messy.
