KIEV, June 1 - The outlook on Ukraine's banking system remains negative, says Moody's Investors Service in a new Banking System Outlook published today.

"The rating agency says that the key drivers of the negative outlook are the challenging operating environment and the strong likelihood of weak economic growth through 2013; the significant stock of non-performing loans (NPLs); the limited availability of local-currency funding; and the banks' weak profitability," according to an agency report.
