MOSCOW, May 29 (RIA Novosti) - The net inflow of foreign capital into Russia's banking system in the first four months of 2008 totaled $3.9 billion, a source close to the Central Bank said on Thursday.

During the period, a net outflow of capital from the Russian economy as a whole was registered, totaling about $5 billion.

In January-March, Russia saw a net private capital outflow of $23 billion, including $7.9 billion from the country's banking sector. The outflow had slowed from more than $11 billion in January to $9 billion in February and $2.5 billion in March.

A net capital inflow of $19 billion was registered in April, and is expected to reach $18 billion in May, the Finance Ministry earlier said.
