SARAJEVO: Bosnia's autonomous Serb Republic will auction 15 million Bosnian marka ($9.9 million) of nine-month treasury bills on Sept. 15 and 30 million marka of 4-year domestic bond on Sept. 22, the finance ministry said on Monday.

Both auctions are aimed to help the region plug a 2014 budget gap that has widened after devastating flooding in May.

The bond interest rate will be fixed at 6 percent annually, the ministry said in a statement. Bosnia also comprises an autonomous federation dominated by Bosniaks and Croats.

It has been issuing short- and long-term debt to cover its own budget gap after the flooding, which caused damage in the whole of Bosnia estimated at 2 billion euro.
