KYIV, Dec 26 - The Fitch Ratings international rating agency forecasts that Ukrainian banks in 2018 will post profit, at the same time it notes a number of constraints.

"Ukraine's banking sector clean-up is well advanced, with high problem loans largely now recognized and banks supported by capital injections from the state or foreign shareholders. The sector should return to profitability in 2018 but provisioning, funding costs and limited growth will weigh on performance," reads a report by the agency.
