Greenium of green securitization: Does external certification matter?

The financing costs of green asset-backed securities (ABS) are deeply affected by the increased information asymmetry and greenwashing risk resulting from risk transferring in securitization. To attract potential investors, many ABS issuers obtain external certifications, yet it is unclear whether they pay off financially. Based on a sample of 588 green ABS issued in China for 2016-2022, this paper examines the impact of external certification in the form of green certification and reputation of financial intermediaries involved in the issuance on the yield discount of green ABS over the paired non-green ABS. The empirical findings show that both external certifications lower the greenium of green ABS by serving as favorable signals and mitigating greenwashing concerns, especially in non-financial industry and the securities exchange market. Moreover, the information asymmetry and credit risk of issuers enhance the pricing effect of financial intermediary certification but undermine that of green certification. Our findings provide valuable implications to facilitate the financing efficiency of green financial markets and promote global low-carbon transition.
