KIEV, Jan. 13 – The decline of the hryvnia exchange rate is linked to seasonal factors such as the fall in business activity and revenue from export of grain crops, the main source of foreign currency in autumn, Deputy National Bank of Ukraine Governor Oleh Churiy said.

"In these conditions the National Bank is ready to enter the market with currency interventions to smooth extra fluctuation [of the exchange rate] and the central bank has enough tools for this," he said.

He said that the central bank announced an auction to sell up to $100 million on Friday.
