The Turkmenistan manat (TMM) is the official currency of Turkmenistan. It is divided into 100 tenge. The Central Bank of Turkmenistan is responsible for issuing and regulating the currency. The manat has been the official currency of Turkmenistan since 1993.The exchange rate of TMM is determined by the Central Bank of Turkmenistan, which generally follows a fixed exchange rate regime. The value of the manat is pegged to the US dollar, but it is not freely convertible. The government of Turkmenistan tightly controls the exchange rate and the availability of foreign currency, making it difficult for individuals and businesses to access foreign currency.Turkmenistan is a country with a centrally planned economy, and the government controls most of the major industries and resources, including oil and natural gas. The country has large reserves of natural resources, but the economy is heavily dependent on the export of these resources.The Turkmenistan manat is not widely used outside of Turkmenistan, and it can be difficult for travelers to exchange or use the currency outside of the country. It is mainly used in Turkmenistan and also in some neighboring countries like Kazakhstan, Uzbekistan, and Iran.It's important to note that the Turkmenistan's economy and currency are heavily dependent on the government policies, which can be unpredictable and subject to change.
