US futures are open and stocks are getting crushed. 

Shortly after futures opened at 6:00 pm ET, S&P 500 futures were down 1.7%, or 37 points, to around 2,060.

Dow futures were off 298 points, or around 1.7%, while Nasdaq futures were also off 1.7%, or around 79 points. 

  

Stocks were following the lead of the euro, which was dropping hard against the dollar, falling 1.7% to below $1.10 while losing more than 2% against the Japanese yen and falling to its lowest level against the British pound since 2007. 

The drop in stocks comes after a wild weekend of headlines out of Greece that saw talks between Greece and its creditors break down, Greece call a referendum vote on the latest bailout terms for next Sunday, while Greek banks and the Athens stock exchange have been closed for at least the next week. 

Greece also has a 1.6 billion payment due to the IMF on Tuesday, which it appears they will miss.
