"The gains of the Swiss franc may boost risk costs at (OTP) Core in Hungary," the bank said in a statement ahead of a press conference.

"OTP's consolidated short- and medium-term growth prospects have not improved, due to external demand which appears to be slowing down," it added.

OTP said earlier in the day that its second-quarter net profit rose by 36 percent from the same period last year. Second-quarter net profit came in at 37.29 billion forint ($195.4 million), against 27.4 billion in the year-ago period.
