German Finance Minister Wolfgang Schaeuble doused expectations of a positive outcome for Greece at an emergency meeting with its official creditors tomorrow, saying there are no plans to give the country more time.

Speaking to reporters in Istanbul after a two-day meeting of finance chiefs from the Group of 20, Schaeuble said "it's over" if Greece doesn't want the final tranche of the current aid program. Greece's creditors also "can't negotiate about something new," Schaeuble said.

Greek government bonds had risen today for the first time in five days on optimism there might be room to move toward an agreement that will help ensure the nation isn't left short of funds. That had come after Greece had offered compromises in a bid to push for a bridge plan to stave off a funding crunch and to buy time for negotiations to ease austerity demands.
