Bank of Industry Limited (abbreviated as 'BOI') is Nigeria's oldest and largest Development Finance Institution (DFI) currently operating.

Initially, International Finance Corporation (IFC) held 75% equity in NIDB and produced the first Managing Director.

GEEP is a ₦140 billion fund aimed at supporting individuals in the informal sector with loans at zero percent interest rate.

[8] As part of efforts to expand financing opportunities, BOI began partnerships with several state governments under a matching fund scheme.

As a result, the project was renamed to the Solar Energy Programme (SEP) to reflect the change in strategic direction.

[10] Pre-paid metres, using Pay-As-You-Go models, were installed in each household and microenterprise to accommodate for flexibility of payment and to solve challenges of unpaid bills.

[11] Through the Solar Energy Programme, the bank aims to power over 100,000 off-grid households and microenterprises in rural and commercial communities by 2021.

[12] In 2011, the Board of Directors of African Development Bank (AfDB) Group approved $500 million multi-tranche line of credit to assist BOI in financing local SMEs Nigeria.

[13][14] The line of credit would be provided for funding projects aimed at systematic poverty reduction, employment generation and wealth creation through entrepreneurial, social and economic development.

[15] As part of the agreement, AfDB required the bank provide technical assistance for capacity building for both BOI and SMEs.

The bank offers a broad range of financial services to micro, small and medium-sized enterprises and various low-income earners both as individuals and as groups.
