The data implies a second quarter net profit of 58.2 billion yuan, up 3% from a year earlier, Reuters calculations show.

The bank said its net interest margin - a key indicator of bank profitability - was 2.02% at the end of June, compared with 2.09% at the end of March.

It reported a 1.41% non-performing loan ratio at the end of the second quarter, holding steady from the end of the previous quarter.
