First Polymer Banknotes in Europe:
In 2005, Romania became the first European country to fully adopt polymer banknotes, which are more durable and less prone to damage than traditional paper notes. Renowned for their distinct colors, these banknotes are considered among the hardest to counterfeit in Europe.
Cultural Heritage Represented:
Romanian banknotes feature motifs and designs inspired by the country’s rich cultural and historical heritage. Themes range from national icons like Mihai Eminescu to natural landmarks such as the Carpathian Mountains. Additionally, each note depicts scenes or motifs associated with notable Romanian individuals.
The Lion Connection:
The term “leu” (meaning “lion”) comes from the Dutch thaler, which had a lion depicted on it. This coin became popular in Eastern Europe in the 17th century, and the name “leu” stuck in Romanian as a reference to its value, eventually becoming the official name of the currency.

History
The Romanian Leu has a rich and diverse history, first introduced in 1867 as part of Romania’s push for a unified and stable monetary system, following years of political fragmentation and economic instability during the mid-19th century.
Throughout its history, the Leu has undergone multiple reforms to adapt to changing economic conditions.
For example, Romania faced hyperinflation during the 1990s.
The economic instability during this period was so severe that it resulted in the introduction of banknotes with very high denominations, such as the 500,000 lei note.
In 1947, a major monetary reform was implemented to address hyperinflation, which included redenomination and revaluation of the currency to restore economic balance.
Most notably, in 2005, Romania reintroduced the Leu, denominating the currency (reducing its value by a factor of 10,000) to simplify its use and stabilize the economy after a period of high inflation.
This modern version, often referred to as the “New Leu” (or “heavy leu” informally), was instrumental in providing economic stability during Romania’s transition towards a market economy.
A Closer Look at the Last Year

The Romanian Leu (RON) has experienced notable fluctuations against major international currencies like the Euro (EUR), the British Pound (GBP), and the United States Dollar (USD) over the last year. Here’s an overview of its performance:
- EUR/RON: The exchange rate began the year around 4.95 RON per EUR, with some early dips below this level in the first quarter, indicating temporary strength in the Romanian Leu. Throughout March and April, the rate saw some upward spikes, and in the middle of the year reaching a level close to 5.00 RON per EUR. After this upward movement, the rate continued to hover around 4.925 to 5.00, suggesting a period of stability. In the latter half of the year, especially from October to December, the rate stabilized near 5.00 RON per EUR, indicating a strong Euro relative to the Romanian Leu.
- GBP/RON: The year started with the exchange rate below 5.60 RON per GBP, indicating a relatively weaker Pound compared to the Romanian Leu. The rate saw some significant fluctuations during the early months, particularly in February where a notable dip occurred, suggesting a period where the Leu gained temporary strength. From March onwards, the exchange rate began an upward movement, reaching above 5.80 RON per GBP by the middle of the year, indicating a strengthening of the British Pound. After peaking in the second half of the year, the rate stabilized, remaining between 5.70 to 5.80, showing a consolidation period for the GBP against the RON.
- USD/RON: At the beginning of the year, the USD/RON exchange rate was just below 4.65 RON per USD. The Romanian Leu initially strengthened, with the rate declining to 4.45 RON per USD. However, there were notable upward movements during February and June, with the rate returning to 4.65 RON per USD. In June, the exchange rate began a further decline, stabilizing around 4.40 RON per USD, indicating increased strength of the Leu. The peak for the USD occurred in October, reaching levels near 4.75 RON per USD, marking a strong period for the dollar. After reaching this high, the exchange rate declined, stabilizing around 4.50 RON per USD toward the end of the year, indicating that the Romanian Leu regained some strength.
Correlations
This correlation matrix compares 5 currency pairs, highlighting how strongly their movements align. High positive values indicate pairs that trend together, while strong negative values suggest inverse moves. Correlations closest to zero reflect the weakest relationships, meaning the pairs move largely independently and can provide diversification opportunities. For the Romanian Leu, the strongest alignment is between RON/CAD and RON/EUR (0.965), showing they often move in the same direction. The weakest connection is between RON/USD and RON/AUD (0.695), where the correlation is closest to zero, indicating minimal relationship in price movements.
The Romanian Leu: What Lies Ahead?

The future of the Romanian Leu (RON) is influenced by both domestic and international economic factors.
Romania, as part of the European Union but not yet a member of the Eurozone, continues to use the Leu, giving it control over its monetary policy through the National Bank of Romania.
This independence allows Romania to tailor its monetary decisions to meet specific national needs, such as controlling inflation or encouraging economic growth.
Romania’s strong trading partnerships within the EU, particularly with Germany, Italy, and France, play a significant role in supporting the value of the Leu.
However, economic challenges such as inflation pressures, global shifts in energy prices, and geopolitical uncertainties may affect the currency’s stability.
The National Bank of Romania remains committed to managing these challenges through targeted monetary policies, including interest rate adjustments and currency interventions aimed at ensuring economic resilience.
Looking ahead, Romania’s gradual steps towards integrating with the Eurozone could influence the Leu’s trajectory, both positively and negatively.
On the positive side, joining the Eurozone could bring economic stability and increased investor confidence.
On the negative side, Romania would lose control over its own monetary policy, which could limit its ability to respond flexibly to domestic economic challenges.
Until then, the Leu is expected to continue reflecting the country’s economic dynamics, with a focus on maintaining stability and promoting sustainable growth.
