Wema Bank Plc said its net interest income was N9.06bn, down from N9.71bn in the first half of last year, while profit before tax stood at N1.17bn, down from N1.70bn in H1 2014.
Its gross earnings were N20.87bn, up from N20.82bn in H1 2014, while other operating expenses dropped to N4.98bn from N5.04bn in the same period last year.
The lender, in a statement on Tuesday announcing its unaudited financial results for the first half of 2015, said its loans and advances were N134.57bn, down from N149.29bn as of December 2014, while deposits from customers stood at N234.10bn, down from N258.96bn as of December 2014.
It put its non-performing loan ratio at 2.9 per cent, compared to 2.5 per cent recorded in the first half of last year.
The bank said the harmonisation of the Cash Reserve Requirements on public and private sector deposits reduced liquidity with significant impact on margins from money market investments.
