Union Bank of India on Wednesday reported a 29.5% rise in net profit for the June quarter to Rs 5,332 crore, helped by higher net interest income, growth in fee income and lower provisions despite a modest rise in credit costs. Net interest income, the difference between interest earned and interest paid, rose 10.1% year-on-year to Rs 10,037 crore as global advances grew 12.5% to Rs 10.96 lakh crore while interest expenses fell 3.6%. Net interest margin improved to 2.80% from 2.76% a year earlier and 2.64% in the preceding quarter.
