Research on access to finance has traditionally focused on microfinance, which provides small loans to self-employed individuals or household businesses. While these studies show that microcredit can increase business activity, they generally find limited impact on profits and job creation. However, small and medium-sized enterprises (SMEs) differ significantly from microenterprises, as they are more established, employ workers, and require larger, formal loans from regulated financial institutions. Despite their importance, evidence on whether such loans help SMEs grow has been mixed and inconclusive.
To address this gap, the analysis draws on 24 rigorous impact evaluations from around the world, focusing specifically on formal loans to existing SMEs rather than microcredit. By synthesizing this broader body of evidence, the study provides a clearer understanding of how access to formal credit affects business outcomes across different contexts.
The findings show that formal loans have a strong positive impact on SME performance. On average, firms that receive such loans experience notable increases in employment, sales, and profits. These gains are significantly larger than those typically observed in microfinance studies, suggesting that formal credit plays a more substantial role in supporting business expansion and job creation.
While outcomes are not guaranteed in every case, the overall likelihood of positive effects is high. The evidence indicates a strong probability that new lending programs will boost employment, sales, and profitability, with negative impacts being relatively rare. This reinforces the overall effectiveness of formal SME lending as a development tool.
The analysis also finds that the positive effects of loans are consistent across different settings. Whether loans are guaranteed or not, issued in high-income or developing countries, or targeted at smaller or larger SMEs, the results remain broadly similar. This suggests that formal lending can support business growth in a wide range of environments.
One notable difference emerges in the type of lender. Loans provided by public financial institutions tend to generate larger employment gains compared to those issued by private banks. This may be because private lenders often favor lower-risk firms, while public institutions are more likely to reach credit-constrained businesses where the potential impact is greater.
However, public banks are not without challenges. Issues such as inefficiency, weak governance, and political influence can limit their effectiveness. This highlights a trade-off between the efficiency of private banks and the potentially higher development impact of public lenders, suggesting that better alignment of incentives and improved financial systems are key to maximizing outcomes.
Overall, the evidence points to three main conclusions: formal SME loans are effective in driving growth, their impact is consistent across different contexts, and the design and incentives of lending institutions play a crucial role in determining their success.
