The Uzbekistani sum is the legal tender of the Republic of Uzbekistan, with the ISO 4217 code UZS and the symbol "so'm" or "сўм".
The Uzbek sum circulates only in the territory of Uzbekistan and is the only official currency of the country.
The Uzbek sum is based on the decimal system, with 1 sum equaling 100 tín. Currently in circulation are banknotes in denominations of 1,000, 5,000, 10,000, 50,000 and 100,000 sum, and coins in denominations of 50, 100, 200 and 500 sum.
The Uzbek sum was officially issued on July 1, 1993, replacing the former Soviet ruble as the national currency of independent Uzbekistan. When it was first issued, the exchange ratio with the ruble was 1 sum = 1,000 rubles. Over the years, Uzbekistan has carried out a number of currency reforms and denomination adjustments.
The exchange rate of the Uzbek sum is determined by market supply and demand, and has experienced large fluctuations in recent years. Due to its large denomination, the currency is often denominated in thousands of sums in daily transactions.
Uzbekistan Soum banknotes use multiple anti-counterfeiting technologies such as watermarks, security lines, invisible patterns, intaglio printing, etc. Banknotes of different denominations are designed with different colors and ethnic patterns.
