The Central Bank of Nigeria (CBN) says it has reviewed weights associated with banks and discount houses’ exposure to risk through the establishment of sound risk management processes.

This was announced in a circular titled “Review of Risk Weights on Certain Exposures in the Computation of Capital Adequacy” issued to banks and discount houses.

The CBN said that it had identified that recent crisis in the banking industry had highlighted several weaknesses in the banking system.

It said that a major contributor was the excessive concentration of credit in the asset portfolios of banks.

The apex bank said that such concentration cut across products, business lines and legal entities, among others.

It, therefore, urged banks to properly manage the concentration through the establishment of sound risk management processes.

The CBN said that it had increased the risk weight assigned to direct lending from 100 per cent to 200 per cent to aid the management of the concentration,

It said that the increment was for the direct lending to local governments, statesministries, departments and agencies of governments.

The CBN said that investments in Federal Government bonds should continue to attract zero per cent risk weight, while state government bonds would remain at 20 per cent.

It said that where the exposure to any industry was in the excess of 20 per cent of the total credit facilities of a bank, the risk weight of the entire portfolio shall be 150 per cent.

The apex bank said that total exposure to a particular industry would include off-balance sheet engagements in which the bank takes the credit risk.

It added that all the breaches of single obligor limits without the prior approval of the CBN should be regarded as impairment to capital.

The CBN said that for the purposes of credit transactions, banks’ related parties within a holding company structure should include the financial holding company and other subsidiaries within the group.
