Hello Belyan,
Thank you very much for your comment. My apologies for not having gotten this right. In my research of each of the various currencies, I never came across information stating that the Lev was pegged to the Euro. In fact, the data quoted in the article comes from Oanda - as referenced in the article itself - and that organization is still reporting daily fluctuations between the Euro and the New Bulgarian Lev. It sounds as if the Lev trades within a range. Is that correct?
All of this is a perfect demonstration of something easy to forget in the modern information era: information discover is not yet entirely perfect. Thank you for your part in making it more perfect!
With smiles,
Jason
