Greece probably won't get all the emergency funds it's requesting for its banks this week, according to two people familiar with the situation.

The Bank of Greece asked the European Central Bank to approve an increase of between 800 million euros ($860 million) and 900 million euros of Emergency Liquidity Assistance, the financial lifeline keeping the country's lenders and the economy afloat, said one of the people. Both asked not to be named because the talks are private.

Greek stocks and three-year notes gained on Thursday after a Finance Ministry official said the government had met its obligation to pay the International Monetary Fund about 450 million euros. The benchmark equity index added 0.5 percent at 2:30 p.m. Athens time. Three-year yields fell 57 basis points to 20.8 percent.
