KIEV, Nov. 25 – The National Bank of Ukraine has bought foreign currency worth over $500 million since early November 2010, which is more than two times more than the October indicator of $237 million, said Valeriy Lytvytsky, the head of the group of advisors to the Governor of the National Bank of Ukraine.

"I forecast that the balance of NBU's transactions would be better this month compared to October, and the trend will strengthen," he said.

Lytvytsky said that in September the negative balance was $600 million, while in October it was $496 million.
