Second Som
On July 1, 1994, a second som was introduced at a rate of 1 new som = 1000 old som. This som is subdivided into 100 tiyin. At its introduction, 1 U.S. dollar was equal to 25 som. Currently, the largest denomination of Uzbek currency, the 1000 som bill, is worth approximately 60 cents U.S., requiring Uzbeks to carry enormous numbers of bills just to carry out grocery shopping and bill payment.
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 the current value by issuing higher coin and note denominations. As a result, the current highest coin denomination in circulation is the 500 som while the highest banknote denomination is the 1000 som. Official state figures put inflation as of the first half of 2011 at 3.6%, however accurate numbers are pinned far higher.
