Eurozone ministers have agreed to give Greece a €7bn (£5bn) bridging loan from an EU-wide fund to keep its finances afloat until a bailout is approved.
The loan is expected to be confirmed on Friday by all EU member states.
In another development, the European Central Bank (ECB) agreed to increase emergency funding to Greece for the first time since it was frozen in June.
The decisions were made after Greek MPs passed tough reforms as part of a eurozone bailout deal.
The bridging loan means Greece will be able to repay debts to the ECB and IMF on Monday.
Greek banks, which have been closed for nearly three weeks, could also reopen on Monday, Greek media reported, although credit controls will remain in place.
