Indicative rates, not an offer.
The Mongolian tögrög (MNT) is the national currency. Besides dollars and euros, Chinese yuan and Russian rubles are exchanged frequently, as Mongolia borders both countries. Almost all offers are in Ulaanbaatar, with more in Erdenet and Darkhan.
Currency is exchanged at banks and exchange offices in central Ulaanbaatar, in large shopping centres and at the airport. For a direct swap of US dollars and tögrög in Mongolia, check the P2P offers on the map.
