Gref said in a televised interview at a conference in Sochi that Sberbank's profit in 2015 would be half as much as in 2014.
But he later told journalists from Russian news agencies that the bank's profit this year would likely be around 30 percent lower than last year.
Sberbank, along with several other large Russian state banks, is under Western sanctions over the Ukraine conflict and has seen its profits hurt by large loan-loss provisions as the economy has slumped.
Its earnings were 44 percent lower than a year earlier in the second quarter.A Message from The Moscow Times:
Dear readers,
We are facing unprecedented challenges. Russia's Prosecutor General's Office has designated The Moscow Times as an "undesirable" organization, criminalizing our work and putting our staff at risk of prosecution. This follows our earlier unjust labeling as a "foreign agent."
These actions are direct attempts to silence independent journalism in Russia. The authorities claim our work "discredits the decisions of the Russian leadership." We see things differently: we strive to provide accurate, unbiased reporting on Russia.
We, the journalists of The Moscow Times, refuse to be silenced. But to continue our work, we need your help.
Your support, no matter how small, makes a world of difference. If you can, please support us monthly starting from just $2. It's quick to set up, and every contribution makes a significant impact.
By supporting The Moscow Times, you're defending open, independent journalism in the face of repression. Thank you for standing with us.
Remind me later.
