An extensive literature supports the principle that barriers to accessing formal external finance prevent all firms from reaching their optimal size, and that greater access to a broad range of financial products can also aid innovation (Ayyagari et al (2017[1]; Aghion, Fally and Scarpetta, 2007[2]). Well-functioning financial markets that allow firms to access alternative sources of financing, outside informal finance and retained earnings allow competitive firms to invest further in tangible assets, to select more efficient organisational forms (Demirguc-Kunt, Love and Maksimovic, 2006[3]), and to ride out periods of stunted or volatile cash flow (Siedschlag et al., 2014[4]).
While all firms seem to benefit from well-functioning financial markets, studies show that this is particularly critical for small to medium-sized enterprises. Studies indicate that financing obstacles do indeed impede growth in small firms, often to a greater extent than in large firms (Beck et al., 2006[5]). Moreover, SMEs often find it harder to access external financing. Financial institutions are often reluctant to lend to this segment – even though it can be perceived as attractive – given the higher risk profile associated with it. This is largely due to the high failure rate among small firms combined with three challenges implicit in SME lending: information asymmetry, principal/agent problems and transaction costs.
Information asymmetry reflects the fact that the owner/operator of an SME tends to have more accurate information on firm operations than an external financier due to the difficulty of capturing all relationships, activities and funds in formal reporting documents like financial statements (OECD, 2015[6]). Principal/agent problems stem from the risk that once financing is received, an entrepreneur may not use the funds in the way they were intended, potentially increasing the risk of non-repayment. SME financing is more exposed to this risk due to the greater opacity surrounding this type of enterprise and the more limited exit options available to them. Finally, transaction costs tend to be higher in SME lending due to the need to conduct the same, or more rigorous, checks for the appraisal, monitoring and enforcement of lower-value loans as for large loans. These fixed costs reduce the lending profit margin for banks and can drive a wedge between the funding costs of such institutions and their expected return on investment (Beck and de la Torre, 2007[7]). Such costs are largely transferred to SMEs via interest rates and fees and collateral requirements, which can render the total loan costs prohibitively expensive.
These three challenges exist in all economies to some extent, but they tend to be particularly pronounced in emerging economies, where SMEs may lack professional management and financial literacy skills, where gaps may exist in the legal framework to protect creditor rights, and where financiers may have more opportunities to gain acceptable returns from other borrowers given limited market-based financing alternatives, and thus less incentive to invest in the skills and technology required to lend to SMEs. This also appears to be the case in ASEAN. Data collected by the International Finance Corporation suggest that SMEs faced a credit shortage totalling USD 184.7 billion in 2010, while a study of seven ASEAN Member States (AMS) found that SMEs tend to experience credit rationing and high risk premiums, particularly in the lower-income AMS and among SMEs that are small and new (Harvie, Narjoko and Oum, 2013[8]). Moreover, the study found limited access to finance to have a significant impact on the innovation capability and export market participation of SMEs.
This identified competitive disadvantage, coupled with the belief that taking corrective action can create positive spillovers for an economy as a whole, is a key rationale for policy intervention in the field of SME finance, particularly in emerging economies. Policy makers wishing to address these gaps can take various steps. They include providing support for the development of institutions to mitigate credit risk, such as credit information facilities and collateral registries, and adopting rules and regulations to protect creditor rights and to streamline settlement procedures in the event of insolvency. The key is to avoid many of the market distortions associated with government-sponsored SME financing programmes and policies that risk diverting funds away from the most productive and creditworthy enterprises. Policy makers should therefore carefully consider where interventions are needed and which instruments are the most suitable, and carefully monitor both their costs and their benefits.
