Uzbekistani sum
The sum is the official currency of Uzbekistan. Uzbekistan replaced the ruble with the sum at par on 16 July 1994. No subdivisions of this sum were initially issued and only banknotes were produced, in denominations of 1, 3, 5, 10, 25, 50, 100, 200, 500, 1,000, 5,000, and 10,000 sum. Further series, however, have introduced coins and a subunit, the tiyin. Because it was meant to be a transitional currency, the original design used during the first years of the republic was rather simplistic.
Etymology
The official name of the Soviet currency in the Kazakh, Kyrgyz, Tajik, and Uzbek languages was the som, and this name appeared written on the back of banknotes, among the texts for the value of the note in all 15 official languages of the USSR. This word translates as 'pure' in several Turkic languages, and is derived from the Proto-Turkic *som, meaning 'pure' or 'solid'. The word implies pure silver or gold.First sum
History
Like other republics of the former Soviet Union, Uzbekistan continued using the Soviet/Russian ruble after independence. On 26 July 1993, a new series of Russian ruble was issued and the old Soviet/Russian ruble ceased to be legal tender in Russia. Some successor states had their national currencies before the change, some chose to continue using the pre-1993 Soviet/Russian ruble, and some chose to use both the pre-1993 and the new Russian ruble. Tables of modern monetary history: Asia implies that both old and new rubles were used in Uzbekistan.Uzbekistan replaced the ruble with the sum at par in on 15 November 1993. No subdivisions of this sum were issued and only banknotes were produced, in denominations of 1, 3, 5, 10, 25, 50, 100, 200, 500, 1,000, 5,000, and 10,000 sum. Because it was meant to be a transitional currency, the design was rather simplistic. All notes had the Coat of arms on the obverse, and Sher-Dor Madrasah of the Registan in Samarkand on the reverse.
Coins
No coins were issued for the first sum.Banknotes
The first banknotes were issued by the State Bank of Uzbekistan in 1993. All of the denominations share the same designs: the Coat of arms of Uzbekistan on the front and the madrasahs on Registan Square in Samarkand.Second sum
History
On 1 July 1994, a second sum was introduced at a rate of 1 new sum = 1,000 old sum. This sum is subdivided into 100 tiyin.Inflation
Until 2013, the largest denomination of Uzbek currency was the 1,000-sum banknote, then worth US$0.60, requiring Uzbeks to carry large bundles of notes for routine transactions.Back in 2019, a new largest denomination was issued, the 100,000-sum banknote, which made the situation easier. The smallest denomination, the 1 tiyin, is worth less than of a US cent making it the "world's most worthless coin" that was still legal tender until 1 March 2020. However, coins and banknotes smaller than 50 sum are rare now.
The rampant inflation situation is considered a politically sensitive issue in Uzbekistan, which is why the Uzbek government is slow to acclimate the currency to its current value by issuing higher coin and note denominations. As a result, the current highest coin denomination in circulation is the 500 sum while the highest banknote denomination is the 200,000 sum. Official state figures put inflation as of the first half of 2011 at 3.6%, however accurate numbers are pinned far higher. Coins and banknotes below 50 sum are practically worthless now.
