Exploring Greenium and the Determinants of Green Bond Performance in Asia
Abstract
This study examines the presence and determinants of the ‘greenium’ in Asian green bonds. The dataset includes green bonds issued by governments and corporations in Asian countries from 2016 to 2022. To analyse the determinants of the greenium, we applied a coarsened exact matching (CEM) model, an advanced form of the matching method. Ordinary least squares (OLS) regression was employed to assess the factors influencing the greenium. Our findings indicate that a greenium exists in green bonds issued in Asia, with significant effects observed in China, Korea, and Japan. Key drivers of the greenium include coupon rates, issuer type, oil prices, and the federal funds rate. This study contributes practical insights by highlighting that a greenium can be achieved through strategic project selection, transparent communication, and strong environmental commitment. Additionally, investors should account for coupon rates, issuer sector, and macroeconomic factors such as oil prices and the federal funds rate when investing in green bonds.
