BUDAPEST--Hungary's largest bank in asset terms, OTP Bank Nyrt. (OTP.BU), appointed George Chesakov as chief executive of its Russian arm.

The appointment is subject to Russian central bank approval. Mr. Chesakov previously worked at Investsberbank, purchased by OTP Bank in 2006, and Russian Standard Bank.

Analysts including Concorde Securities say OTP is facing problems in Russia, amid falling demand for point-of-sales loans and a decline in credit quality after many years of prolific operation. This has marred the bank's Russian profit performance and outlook, Concorde analyst Attila Gyurcsik said in a recent note to investors.

OTP was trading down 0.4% or HUF17 at HUF4,280 at 0852 GMT.
