"One can only suspect political motives behind the fact that the institutions insist on further pension cuts, despite five years of pillaging via the memoranda.

We will wait patiently till the institutions adhere to realism," Tsipras said in a statement after the meeting.
Bond yields in the "peripheral" stocks of Italy, Spain and Portugal – countries that were caught up in the market turmoil of the 2012 euro zone debt crisis -- were hit with contagion selling, with Italian 10-year yields at 2.4 percent, levels not seen since mid-November last year.
Portugal and Spain 10-year paper traded at 3.3 and 2.3 percent respectively. Meanwhile German bund yields were pushed down as investors rushed to the perceived "safe-haven".
Greek banks also under pressure on Monday as investors digested the news, with Pireaus Bank tumbling as much 15 percent, while Alpha Bank and Eurobank Ergasias both slipped around 12 percent. Italian and Spanish banking stocks also fell sharply.

"Any agreement needs to be approved by the various euro area parliaments, including the German Bundestag. Since the German Bundestag closes for the summer recess on 3rd July, there may not be time to get the legislation passed if the negotiations spill into next week," he added.
