The Greenium : A study of pricing on the fixed income market

Abstract: This thesis studies the yield differential between green bonds and conventional bonds, the so called green premium or "greenium". By deriving a theoretical model that includes investors' preferences for green assets, two hypothesis are formulated: There exists a negative green bond premium and The negative premium is larger in absolute terms in countries with high environmental performance. In order to estimate the premium, synthetic conventional bonds are constructed having the same characteristics as the green bonds. Two different matching methods are used to construct the synthetic bonds, one based on maturity and one based on correlation. The findings of this study suggest a significant negative green premium between -0.29 and -0.78 basis points. Also, the green premium is more than twice as large, in terms of absolute value, if the issuer is based in a country which has a high environmental performance.
