National Bank of Kenya posted a 17 percent fall in first-half profit to 911.8 million shillings from the 1.1 billion shillings posted a year earlier. The bank’s profitability was weighed down by high interest expenses which rose five fold as the bank tried to retain its more affluent clients. The dip in profits will give incoming CEO Munir Sheikh Ahmed a lot to work on to get the bank back on track to profitability after years of loss making.
