Banji Adenusi In December 2013, the Central Bank of Nigeria released the guidelines on the implementation of Basel II/III recommendations of the Basel Committee on Banking Supervision, which implementation took effect from January 2014. While the timeframe for implementation of the minimum capital adequacy computation under Basel II rules will commence in June 2014, the banks have already begun a parallel run of the Basel II capital adequacy computation along with existing Basel I requirements. In specifying the approaches for quantifying the risk-weighted assets for the purpose of determining regulatory capital, the banks are required to adopt the standardised approach in relation to market and credit risks, with the basic indicator approach adopted for operational risk. Rather than adopt a sweeping endorsement of the Basel II/III accords however, the Central Bank (CBN) has modified the guidelines, taking into consideration the present realities of the Nigerian banking system. Credit risk modifications abound in the risk weight assigned to inter-bank transactions and exposures guaranteed by the Federal Government of Nigeria (FGN) or CBN, exposures to FGN or CBN transactions denominated in naira and funded in that currency, amongst others, which carry risk weight of 0%. Other modifications include exposures secured by residential mortgage loans, which carry a risk weight of 100%, compared to the recommended 35% in the Basel II accord. Unrated on-balance sheet securitisation carries a risk weight of 1250%, whereas the Basel II accord provides no risk weight for such transaction.
