KIEV, March 24 – The U.S. dollar exchange rate will continue to fall against the Ukrainian national currency, the hryvnia, if the National Bank of Ukraine doesn't begin to buy excess supply of the dollar on the interbank market, according to bankers polled by Interfax-Ukraine on Monday.

"If the NBU appears on the interbank to support the weakening dollar, the situation will calm down soon, although at a new level. The question is at which level the NBU will intervene – UAH/$ 4.80 or 4.95. If the NBU doesn't appear this week again, the cash rate may go down to UAH/$ 4.80 or even 4.50," Erik Naiman at Ukrsotsbank told Interfax-Ukraine on Monday.
