KIEV: Ukraine's central bank offered on Monday to buy dollars at a rate of 26.86 hryvnias on the interbank market, following three interventions last week to limit volatility for the struggling national currency.

On Friday, the bank bought $62.35 million at a rate of 27.5 hryvnias to the dollar.

The hryvnia has halved in value so far in 2015, having weakened 50 percent last year. On Monday, the average rate of bank trades for Ukraine's hryvnia registered by the central bank stood at 26.63 to the dollar.
