KIEV, July 2 - The National Bank of Ukraine by late 2007 could buy another $2 billion on the interbank exchange, while at present its international reserves have reached $25 billion, which is equal to 4.6 months of imports, First Deputy NBU Head Anatoliy Shapovalov told Interfax-Ukraine last week.

"I think that we'll buy a couple of billion by the end of the year," he said.

Shapovalov said that the activity of the national bank on the currency market would depend on the price of imported gas. Moreover, he said that in fall demand on currency traditionally grows.
