The Greek government confirmed on Monday that banks will remain shut all week, to prevent banks from collapsing under the weight of mass withdrawals following a decision by the European Central Bank not to extend emergency funding. Greeks woke up to shuttered banks, closed cash machines and a climate of rumors and conspiracy theories on Monday, as a breakdown in talks between Athens and its creditors pushed the austerity-battered country to the brink. After receiving no extra emergency funding for Greek lenders from the European Central Bank, Prime Minister Alexis Tsipras reluctantly imposed capital controls on Sunday night.Greece has to pay back 1.6 billion euros ($1.77 billion) of International Monetary Fund loans until tonight, and a default would set in train events that could lead to the country's eventual exit from the euro currency bloc. But after Tsipras angered Greece's international lenders by announcing a snap referendum on the terms of a cash-for-reforms deal, hopes of a last-minute breakthrough are fading fast."I can't believe it," said Athens resident Evgenia Gekou, 50, on her way to work. "I keep thinking we will wake up tomorrow and everything will be OK. I'm trying hard not to worry." The government will keep banks shut at least until after July 5, the date of the referendum, and withdrawals from automated teller machines - which were shut yesterday - will be limited to 60 euros a day when they reopen today. After months of wrangling, Greece's exasperated European partners have put the blame for the crisis squarely on Tsipras's shoulders. The creditors wanted Greece to cut pensions and raise taxes in ways that Tsipras has long argued would deepen one of the worst economic crises of modern times in a country where a quarter of the workforce is already unemployed.As Tsipras announced the emergency measures late on Sunday, there were long queues outside ATMs and petrol stations as people raced to take out cash before it was too late. "I've got five euros in my pocket, I thought I would try my luck here for some money. The queues in my neighborhood were too long yesterday," said plumber Yannis Kalaizakis, 58, outside an empty cash machine in central Athens yesterday. "I don't know what else to say. It's a mess."Newspapers splashed pictures of long lines outside cash machines on their front page. The Nafetemporiki daily headlined Monday's edition "Dramatic hours," while the Ta Nea daily simply said: "When will the banks open?" The conservative-leaning Eleftheros Typos newspaper accused Tsipras of announcing the referendum as a ruse to tip the country into early elections in the hopes of winning them."Mr. Tsipras's decision to call a referendum and a possible euro exit constitutes a premeditated crime," it said in an editorial. "It is clear that Mr. Tsipras has lost the trust of citizens. That's obvious from the queues at ATMs and petrol stations, and it will become obvious at next Sunday's ballot."As rumors flew about, dozens of pensioners queued outside at least two offices of the National Bank of Greece on Monday after hearing they could withdraw pensions from some branches. They were turned away, Reuter's photographers said. "I've worked all my life, only to wake up one morning to a disaster like this," said one shop owner, who was there to collect his wife's pension.Despite the financial shock, elements of daily life went on as normal, with shops, pharmacies and supermarkets in the city opening, and Greeks meeting to discuss their country's fate at cafes and restaurants. Tourists gathered as usual to watch the changing of the presidential guard outside parliament.A rally to protest against austerity measures and urge voters to say "No" in the referendum on bailout terms is expected later on Monday.Despite the hardening of positions, officials around Europe and the U.S. made a frantic round of calls and organized meetings to try to salvage the situation.U.S. President Barack Obama called German Chancellor Angela Merkel, and senior U.S. officials including Treasury Secretary Jack Lew, who spoke to Tsipras, urged Europe and the IMF to come up with a plan to hold the single currency together and keep Greece in the eurozone. The German and French governments announced emergency political meetings. "While the program is active until Tuesday, they aren't providing the necessary liquidity for Greek banks just to blackmail and to terrorize us," Administrative Reforms Minister George Katrougalos told Antenna television. "If we vote a yes, they will demolish pensions, you will have to pay for Medicare in public hospitals. When your kids can't go to school you will say 'thanks' and they will say 'you asked for it'. "But if you say no, you have the ability to fight for a better future.
