Nigerian banks whose earnings have been hit by the Central Bank of Nigeria’s (CBN) tight monetary policies will see profits rebound once easing begins as early as the second half of 2015, Nigeria's This Day Live reported. Nigerian banks’ profitability is largely a function of macro stability, and any significant improvement in sector earnings is likely to be driven by a loosening of monetary policy,said, Renaissance Capital SSA banking analyst Adesoji Solanke. The CBN hiked the cash reserve ratio (CRR) on public sector funds for lenders to 75% in a bid to stem excess liquidity and protect the naira.
