The Serbian central bank, meeting on Thursday, did not react to the past few months dinar selling with a cut in its 3 percent benchmark rate, the highest in the region, citing a rise in inflation and in the interest rates of leading central banks.

Czech annual inflation retreated to 2.3 percent in July from 2.6 percent in June according to data published on Thursday.
