KYIV, Aug 28 - The hryvnia by the end of September may weaken to a maximum of UAH 28.2/$1 due to seasonal factors, including the return of the market to business activity and the next launch of the economy, a banker said.

"Historically, at the end of August and at the beginning of September in Ukraine there is an increase in the hryvnia to U.S. dollar exchange rate. This is associated with the return of the market to business activity and the next launch of the economy. The market expects the dollar rate to rise. I think the maximum values in the interbank market that we will see during this period are UAH 28.15-28.20/$1," Yuriy Yefremov, the director of the treasury department of Accordbank, said.
