The Central Bank of Nigeria (CBN) and commercial banks in the country came under fire yesterday over disparities in deposit and lending rates obtainable in their offices. The upper legislative chamber lamented that interest rate on loans operated by commercial banks and approved by the CBN remained one of the highest in the world. Angered by the development, the Senate mandated its Committee on Financial Institutions to investigate and report back its findings to enable it take a definite position on the matter.
