Industrial and Commercial Bank of China said Tuesday in its interim results for the first six months of this year that it earned a net profit of 150.7 billion yuan. That was up 0.8 percent from the same period last year.

The bank said that its margins narrowed to 2.21 percent at the end of June from 2.28 percent at the end of the first quarter.

The bank said that successive interest rate cuts and repricing of deposits and loans narrowed its interest spread. In the mean time, the bank said its non-performing loan ratio decreased to 1.55 percent at the end of June from 1.66 percent at the end of March.

The bank was the only one among China's five biggest to see a fall in its NPL ratio.
