LONDON, May 30 - The outlook for Ukraine's banking system remains negative, unchanged since October 2009, Moody's Investors Service said in a new report published on Thursday.

The outlook reflects the rating agency's expectation that Ukrainian banks will continue to operate in a challenging economic environment, causing asset quality to remain very weak, the report says. This outlook also takes into account Moody's expectation of poor profitability and tighter funding conditions in 2013.
