MOSCOW--Russia's state-controlled bank VTB Bank said on Friday that its 2014 net profit was almost wiped out during "a very challenging year for both the Russian economy and the banking sector."

The country's second-largest lender, battered by Western sanctions and high interest rates imposed to stem the ruble's plunge, said its profit plummeted to 800 million rubles ($13.1 million) from a record 100.5 billion rubles in the previous year.

The result is better than analysts' expectations and comes despite a warning from Chief Executive Andrei Kostin that the bank could make its first loss in five years.

Once the flagship of the Kremlin's drive to create a Western-style global banking giant, VTB has found itself cut off from world financial markets by sanctions imposed last summer amid the crisis in Ukraine.

"Our clients were affected by an economic slowdown and tough geopolitical environment, as well as by the rapid depreciation of the ruble and subsequent spike in interest rates," said Mr. Kostin as the bank presented its earnings.

This led to higher risk costs despite strong operational results.

The bank said its provision charge for impairment is up to 275.4 billion rubles from 99.2 billion rubles in 2013, and return on capital dropped to just 0.1% in 2014 from 11.8% in 2013.
