The sale price of the dollar "has been adjusted to 1,182 dinars," the central bank said in a statement on Monday.
The previous price was 1,166 dinars for a dollar, Mudher Saleh, a top economic adviser to Prime Minister Haider al-Abadi and former deputy central bank governor, told Reuters.
"This is a small adjustment, it's not a devaluation. It will increase government revenue to meet local needs," said Saleh.
