With the clock running down on Greece's chances of avoiding a painful exit from the euro, the country got a temporary lifeline Friday to help it cope with a bank deposit drain and turned its hopes to a European leaders' summit next week.
The European Union president warned the situation was "getting critical" as Greece approaches a deadline on June 30, when it has to make a debt repayment it cannot afford without more loans from creditors.
Uncertainty over whether Greece might default on that payment – something that could lead to the country eventually falling out of the euro – increased after a meeting Thursday ended in discord over what reforms the country should make to get more loans.
Several European countries are now openly saying they are getting ready for the possibility that Greece might leave the euro.
"The game of chicken needs to end and so does the blame game," EU President Donald Tusk said in a video message.
"We are close to the point where the Greek government will have to choose between accepting what I believe is a good offer of continued support or to head towards default."
In the streets of Athens, there were no visible signs of distress or larger than usual lines at banks or supermarkets. Officials, however, signaled an increase in withdrawals and transfers, which can also be made electronically.
An EU official said Greeks had taken about 2 billion euros ($2.3 billion) out of their accounts in the last three days.
"Money is going out of the Greek banks faster than at any time before," said the official, who spoke only on condition of anonymity because of the sensitive nature of the situation.
As a result, the European Central Bank's governing council decided to provide more emergency credit for Greece's banks to help them cope with the situation.
A Greek banking official, who spoke on condition of anonymity because the announcement was not made public, confirmed the decision. The official declined to give a sum.
The ECB has been steadily increasing the support it allows Greek banks to draw on. It's not thought it would turn off that tap until it thinks Greece is definitely going bust, and certainly not before an emergency summit of the eurozone's 19 leaders on Monday.
However, if no deal emerges with creditors soon that will allow the country to pay upcoming debt payments, starting with one at the end of the month, the ECB would be under intense pressure to stop pumping money into a banking system that might collapse.
The creditors want Greece to agree to new reforms and a tighter budget before they give it more loans. Greece's radical left-led government, on the other hand, came to power in January on the promise to end such measures, which may have helped tame the budget deficit but have also increased poverty and unemployment.
Greece has to pay 1.6 billion euros to the International Monetary Fund on June 30. It cannot afford that without a deal that would unlock 7.2 billion euros in bailout loans.
Around Greece on Friday, newspaper headlines warned time was running out. The daily Ethnos called Monday's summit the "Last Chance for a Deal" while the pro-government Efimerida ton Syntakton said creditors had put a "Knife to our Throat."
Athenian Giorgos Tsakoyiannis, 55, said he believed a deal would emerge eventually.
"When two parties want to resolve something, there's no way it won't happen," he said. "It looks extreme, but politics is never extreme. It's a dirty game."
Greek Prime Minister Alexis Tsipras, who visited Russia to meet President Vladimir Putin, sought to portray Monday's summit as "a positive development on the road to agreement." He claimed that those "who invest in crisis and horror scenarios will be proven wrong."
"We sought final negotiations to be at the highest political level in Europe and now we are working for the success of this summit," he said. The central bank of Greece said "the gap between Greece and its creditors is not a large one."
As finance ministers from across the 28-country EU wrapped up talks in Luxembourg on Friday, there were indications that technical talks would resume over the weekend before eurozone finance ministers meet again on Monday ahead of the leaders' summit later in the day.
"We are a little skeptical that we will be able to prepare a great deal more than today," German Finance Minister Wolfgang Schaeuble said. "But maybe the readiness in Greece to do what is necessary will increase over the weekend. The ball is in Greece's court."
"I'm not so sure that I will be able to announce sensational news to you on Monday," he said.
It's not just eurozone countries that would be affected by a Greek exit from the euro. Some investors think a so-called Grexit could be another "Lehman Brothers" moment for the world economy – sparking a potentially destabilizing chain reaction, the way the collapse of the investment bank did in 2008. Others say it would be manageable, though the uncertainties are great.
"In the United Kingdom we've taken the measures to increase our economic security so we can deal with risks like this from abroad and clearly now we must go on and complete that plan," said George Osborne, Britain's finance minister.
Slovakia's prime minister, Robert Fico, said his country was "technically prepared" for a Greek euro exit. "We wish for Greece to remain in the eurozone but not at all costs."
Investors appeared to take developments in stride, with the Stoxx 50 index of leading European shares up 0.3 percent. The main stock market in Athens closed up 0.6 percent.
