KYIV, May 31 – The National Bank of Ukraine (NBU) could toughen its monetary policy and introduce some currency restrictions if the inflation pressure worsens and if Ukraine fails to receive the new tranche from the International Monetary Fund (IMF) under the Extended Fund Facility (EFF), NBU Governor Yakiv Smolii said.

"If the inflation pressure grows, of course, the NBU would strengthen monetary tools to curb inflation. We will introduce some restrictions for preventing the possible removal of capital," he said at a joint press conference of central banks of Ukraine and Poland in Kyiv on Thursday.
