The same Caragiale. Four fewer zeros.

In December 2003, Romania issued a polymer banknote with a face value of one million lei. Less than two years later, on 1 July 2005, that converted nominal value became 100 lei. Playwright Ion Luca Caragiale remained on the front of the bill; the four trailing zeros vanished from the currency.

A currency can be denominated in a day. Language transforms over time.

On 1 July 2005, banks and corporate accounting systems applied the rule in a single day: 10,000 old lei became one new leu. In everyday life, the “million” had served as a common price scale during the high-inflation years following 1989, when wages, rents, and major transactions were routinely calculated in those units.

Research in the anthropology of money (including work by Bill Maurer and Keith Hart) shows that state-issued official currency frequently coexists with vernacular community customs. In Romania, journalistic field reports (such as Digi24's coverage) document this persistence of old-currency reckoning. For example, a person may withdraw 5,000 lei from an ATM and still say “fifty million” at open-air markets or in informal negotiations.

An administrative reform replaces banknotes in circulation, but customary habits of expression transform at their own pace. Over two decades after denomination, press reporting and everyday observation indicate that speaking in “millions” persists primarily in informal contexts, rounded figures, and household budget conversations.

Before July 2005, these were literal nominal values. After denomination, the terms persisted in informal conversation.

Denomination or inflation?

The conversion 1,000,000 ROL = 100 RON is a strict nominal denomination mandated by Law no. 348/2004. This mathematical ratio does not measure purchasing power over time.

A sum of one million old lei in the year 2000 or 2004 provided different purchasing power than 100 lei in 2026. Evaluating the historical purchasing power of money requires computing the consumer price index (CPI), a separate operation from currency denomination.

When did Romania denominate its currency?

Denomination occurred on 1 July 2005 under Law no. 348/2004. Dual price displays operated between 1 March 2005 and 30 June 2006, and old banknotes circulated alongside new polymer bills until 31 December 2006.

Does the ROL to RON conversion account for inflation?

No. Denomination is a nominal scaling operation at 10,000:1. The historical purchasing power of money varies with consumer price inflation and is evaluated using price indices.

Why do Romanians still speak in “millions”?

High inflation during the 1990s and early 2000s shaped the price benchmarks of several generations in millions. This linguistic inertia keeps the expression alive in casual conversation, even though official transactions use new lei exclusively.
