With increasing concern over climate change, many see green finance as a solution to fund sustainable projects. In particular, green bonds—a type of debt instrument which aims to finance sustainable infrastructure projects—are growing in popularity. While the literature does not contest their effectiveness in fighting climate change, research highlights the high level of risks and low returns associated with this instrument. This research investigates green bonds’ characteristics, depending on the issuing region, with a special focus on Asia and the Pacific. Our findings prove that green bonds in Asia tend to show higher returns but higher risks and higher heterogeneity. Generally, the Asian green bonds market is dominated by the banking sector, representing 60% of all issuance. Given that bonds issued by this sector tend to show lower returns than average, we recommend policies that could increase the rate of return of bonds issued by the banking sector through the use of tax spillover. Diversification of issuers, with higher participation from the public sector or de-risking policies, could also be considered.

Small and medium-sized enterprises (SMEs) are the backbone of the Asian economy. They make up more than 96% of all Asian businesses, providing two out of three private-sector jobs on the continent. Therefore, it is vital for Asia’s economic success that fully functioning support measures for SMEs are in place. However, SMEs face major challenges in accessing cheap finance, mainly because of the asymmetric information problem between suppliers and users of funds and high transaction costs. These lead to more collateral requirements for lending to SMEs with higher lending interest rates, which hinder their growth. As most Asian countries are bank-dominant economies, capital market financing is not a realistic option for SMEs. Therefore, we need to look for solutions that simplify banks’ lending to SMEs. This chapter will highlight the difficulties faced by SMEs in accessing finance and provide measures for mitigating them. The remedies proposed in this chapter include the development of a credit information infrastructure for SMEs, the utilization of credit-rating techniques for SMEs to address the problem of asymmetric information, and the development of a sustainable credit guarantee scheme to resolve the collateral issue.

Small and medium-sized enterprise (SMEs) often face severe difficulties raising money. Considering the bank-dominated characteristic of Asian economies, banks are the main source of financing. In order to prevent the accumulation of nonperforming loans in the SME sector, it is crucial for banks to distinguish healthy SMEs from risky ones. This chapter examines how a credit rating scheme for SMEs can be developed when financial and non-financial data are not accessible just by using lending data of banks to SMEs. We employ statistical techniques on five variables from a sample of 3,272 Thai SMEs and classify them into subgroups based on their financial health. The source of data used for the credit risk analysis in this research is the National Credit Bureau of Thailand. By employing these techniques, banks could reduce information asymmetry and consequently set interest rates and lending ceilings for SMEs. This would ease financing to healthy SMEs and reduce the number of nonperforming loans to this important sector.
