Birr is the official currency of Ethiopia, symbolized by "Br" and subdivided into 100 cents. It was introduced in 1945, replacing the Ethiopian dollar. The birr is issued by the National Bank of Ethiopia and plays a crucial role in the country's economy, facilitating trade and commerce. The value of the birr can fluctuate due to various factors, including inflation and economic policies. As a developing nation, Ethiopia has faced challenges that impact the birr's stability, making it important for citizens and businesses to stay informed about currency trends and exchange rates.
