"The floatation will most likely take place in the first half of the fall, but everything will depend on the market situation," the source said.
In late June, VTB Finance Director Nikolai Tsekhomsky said the bank planned to issue at least $1 bln worth of Eurobonds to pay off its debt.
It was earlier reported that the bank's total foreign borrowings this year could reach $5 bln.
In November, VTB floated Eurobonds totaling $2 billion.
Tsekhomsky earlier said VTB considered U.S. pension funds to be the most attractive investors, with their extensive reserves.
He also said receipts from the sale of a 5% stake in the European Aeronautic Defense and Space Company (EADS), acquired in 2006 for about $1 billion, would be used to finance retail credit. VTB sold the stake in EADS for about the same sum to another state bank, Vnesheconombank, at the end of last year.
