An IMF bailout tranche worth $3.8 billion, which may not be released to Ukraine by the end of the year as planned, is not crucial for the currency market and economy, acting Finance Minister Ihor Umansky said on Wednesday, according to Reuters.

"This tranche is not crucial for ensuring balance on the currency markets. I do not see any risks to the economy (if the tranche is delayed)," Umansky told journalists.
