KIEV, Dec. 28 – The strengthening of the hryvnia exchange rate at the end of 2012 to a level close to the level at the beginning of the year proves that the currency policy of the National Bank of Ukraine is correct, said Valeriy Lytvytsky, the head of the group of advisors to the NBU governor.

"Where are those experts who predicted the UAH 8.50/$1 or UAH 9.00/$1 exchange rate for the end of the year? The NBU again proved that there is consistency between what it said and what it did, and the exchange policy is not divided into phases of the political cycle," he told Interfax-Ukraine on Friday.
