KIEV, Feb. 24 – The decrease of the hryvnia exchange rate on the interbank currency market continue being caused by both temporary and fundamental market factors that result in the reduction of supply of foreign currency, Deputy National Bank of Ukraine Governor Oleh Churiy said.

"The seasonal decline in business activity in January entailed the fall in supply of income in foreign currency in February, and political instability and a delay with the resumption of cooperation with the International Monetary Fund affect business expectations," he said in a report spread by the central bank late on Tuesday.
