Greece delivered to Brussels Tuesday a delayed but what it called "very comprehensive" list of reforms that Athens hopes will secure a four-month extension to its financial lifeline.
Eurozone finance ministers are to discuss them in a conference call on Tuesday afternoon.
"Greece's inability to deliver their reform plan by Monday's deadline hasn't caused too many tremors in the markets," noted London Capital Group dealer Jonathan Sudaria.
Most European indices had risen on Monday after eurozone ministers tentatively agreed to extend Greece's bailout by four months, but London slid on poor results from HSBC bank.
"Most investors are waiting for statements from the US financial authorities and the submission of Greece's economic policies," Toshihiko Matsuno, chief strategist at SMBC Friend Securities, told Bloomberg News.
After missing a Monday deadline, Greece delivered to Brussels on Tuesday what it called a "very comprehensive" list of reforms that Athens hopes will secure a four-month extension to its financial lifeline. The news sent the Athens stock market soaring 7%.
A conditional deal that would let Athens pay its bills and avoid a disastrous default is contingent on reforms deemed satisfactory by the so-called "troika" -- the European Commission, the European Central Bank and the International Monetary Fund.
Time is of the essence and the stakes are high, with Greece's current 240-billion-euro ($270-billion) bailout programme due to expire on Saturday and several European parliaments still needing to approve any extension.
If Athens fails to win more time and the bailout expires, Prime Minister Alexis Tsipras's month-old government risks running out of money, triggering a likely run on banks and even possible ejection from the 19-country eurozone.
But analysts warned that a bailout extension would only offer temporary relief.
"A more detailed reform programme needs to be agreed by April," Ray Attrill, global co-head of foreign exchange strategy at National Australia Bank, said in a note.
"So whatever happens later today, the Greece issue cannot be... put to bed for another 3-4 months."
