The currency of Romania is the Romanian leu, abbreviated as RON. The leu has undergone several fluctuations in value since it was first introduced in the 19th century, and it has been adjusted multiple times to accommodate various economic changes. The currency symbol for the leu is "lei," plural for "leu." As a member of the European Union, Romania has considered adopting the euro as its official currency, but this transition has not yet occurred. The leu is subdivided into 100 bani, and various banknotes and coins are in circulation, reflecting Romania's history and culture.
