Scholars argue that judging by the poor economic development of the informal sector, not much progress seems to have been achieved, despite government efforts to promote SME activity. Some of the key factors attributed to this poor performance is access to financial services. Therefore, the purpose of this study was to examine the contribution of commercial banks in economic development of SMEs Normally, SMES play vital and significant contributors to economic development through their critical role in providing job opportunities and reducing poverty levels, an estimated number of up to 40% of the start-ups SMEs fail by year 2 and at least 60% close their doors by year 4. This menace is attributed to poor financial management among small businesses. Accessing credit is a major constraint to the economic development and growth of SMEs and also to poor rural and urban households. This is mainly due to the behavior of lenders in terms of hedging against borrowers’ risks by demanding collateral, which they lack, and also information asymmetry.
