KIEV, April 17 – The hryvnia exchange rate could strengthen on the introduction of administrative measures to limit demand for foreign currency by the National Bank of Ukraine, according to Valeriy Lytvytsky, the head of the group of advisors to the NBU governor.

"The introduction of administrative measures is a proper reaction to the situation when economic methods fail, while psychological factors play a larger role than under the usual conditions... If the strengthening were superfluous, the NBU would suppress this wave," he told Interfax-Ukraine on Thursday.
