One of the most influential rating agencies Moody's upgraded Bulgaria's credit rating in foreign currency from B1 to Ba2 Thursday. Bulgarian Parliament's foreign and local currency credit rating is also upgraded to Ba1. The fact that Bulgaria's foreign debt has dropped by nearly EUR 2 B is one of the main reasons for the upgrading, experts at Moody's explained. Bulgaria's ambitions to complete EU membership negotiations in 2004 and become full member in 2007 is pointed as another key reason. Bulgaria should keep low current account deficit and speed up structural reforms to achieve even more positive results, Moody's experts said.
