ISTANBUL--Turkey's Is Bank (ISCTR.IS) on Wednesday reported a 17.8% rise in second-quarter net profit, driven by rising net interest income and trading gains.

Is Bank, based in Istanbul, said its unconsolidated net profit rose to 952.8 million Turkish lira ($532.4 million) from TRY808.6 million a year earlier. The result was above the average TRY821 million forecast of analysts polled earlier by Dow Jones Newswires.

Its net interest income rose 32.7% to TRY1.428 billion from TRY1.076 billion.

At 1315 GMT, Is Bank's shares were 1.9% lower at TRY5.2. The overall Istanbul market was down 0.2%.
