After the ECB and Germany agreed to pay the loans to Greece, the Greek banks will reopen on Sunday after being shut for 3 weeks. European finance ministers approved an interim loan worth seven billion euros ($7.6 billion) to help Greece pay its most urgent debts in the next few days. Then the European Central Bank (ECB) said it would pump 900 million euros in emergency funding into Greek banks, which have been shut for nearly three weeks. But the new cash won't provide immediate relief for Greeks. The government said banks would stay shut through Sunday. A banking source said the banks were ready to resume limited operations on Monday, but the government had yet to make that decision, CNN reported. Europe's moves to restore funding to Greece came after the Greek parliament backed a proposed three-year rescue package -- worth as much as $96 billion -- overnight, and passed into law several key economic reforms set by creditors as preconditions for a deal. The details of the new rescue will take weeks to negotiate but Greece needs money now -- to clear its arrears of about two billion euros with the International Monetary Fund, and to make a debt repayment of 3.5 billion euros to the ECB on Monday. Its banks also need money to stay afloat. The ECB had been turning down requests for more cash since the government abandoned bailout talks in late June.
