The Mongolian dollar is a term that can refer to the currency of Mongolia, known as the Mongolian tögrög. The tögrög is abbreviated as MNT and is used for all transactions within the country. It was introduced in 1925, replacing the previous currency, and has undergone several changes since then. The value of the tögrög can fluctuate based on economic conditions, including inflation and foreign exchange rates. The Central Bank of Mongolia is responsible for issuing and regulating the currency, ensuring stability in the financial system.
