Why is the BNR official rate published for the RON, so important in Romania?
Everywhere I look for the exchange rates in Romania to the Euro, romanian websites display a "Curs BNR" rate.
I understand that this refers to the currency rate published by the National Bank of Romania. But: why is this BNR rate so important (compared to the normal "market" rate we can find in Google Finance)? Is this BNR rate used for a specific calculation at banking level?
