Greek drama continues to weigh on Wall Street

U.S. stock index futures futures pointed to a lower open on Monday, with Wall Street looking set to follow European stocks down, as talks between Greece and its creditors collapsed once again at the weekend.

The Dow Jones industrial futures were more than 100 points lower in morning trade, following declines in both European and Asian markets on the prospect of Greece defaulting on its debt obligations.

Athens and its creditors held tortuous talks over the weekend which failed to resolve the impasse over reforms, with European officials blaming Greece for failing to offer concessions in return for a final tranche of desperately-needed financial aid.

Greek banks sold off sharply, with most lenders in the country down over 10 percent on Monday, weighing on other European banking stocks.
