Uzbek soums Buy: 3.8 / Sell: 4.3 / National Bank rate: 3.84

Initially introduced on November 15, 1993, as sum-kupons—a currency parallel to the Soviet ruble—to protect the country's economy from excess ruble supply. Since July 1, 1994, it has been the sole legal tender in Uzbekistan. Currently, all banknotes (except for the 1992 coupons) and coins are de jure legal tender, but denominations of less than 100 sums (approximately 80 kopecks) are not used.

The modern sum was introduced into circulation at a ratio of 1 sum = 1000 sum-coupons on July 1, 1994, by Decree of the President of Uzbekistan No. UP-870 of June 16, 1994, "On the introduction of the national currency of the Republic of Uzbekistan into circulation", in accordance with the Resolution of the Supreme Council of the Republic of Uzbekistan dated September 3, 1993, No. 952-XII. Since August 1, 1994, the sum has been the only legal tender in the territory of the Republic of Uzbekistan.

As a result of the liberalization of foreign exchange policy, the Central Bank's exchange rate against the US dollar was set at 1 USD = 8,100 UZS on September 5, 2017, with an expected range of 8,000–8,150 UZS per US dollar.

Uzbek soum denominations, banknotes, and bills: 1, 3, 5, 10, 25, 50, 100, 200, 500, 1,000, and 5,000 UZS.
