Many large firms today grew from small and medium-scale enterprises. Access to the credit market is indispensable for SMEs to grow. Large credit rating firms, such as Moody’s, Standard & Poor’s, and Fitch, usually rate large firms. Thus, large firms can have easy access to credit provided they are financially sound. In the case of SMEs, such rating schemes are scarce. Due to the lack of credit rating indices, it is natural that banks perceive investment on SMEs to be risky. From the lender’s point of view, it is costly to examine the financial health of each and every SME. This cost is also passed on to SMEs, thereby increasing their borrowing costs.
