Usual integrated ESG analysis (examining an issuer’s ESG characteristics relative to sector peers and deriving an overall A-E rating with trend) does not fully address sustainability bonds because of the way these securities target specific projects.
‘Although unlikely, an A-rated ESG issuer could theoretically issue a low-quality sustainability bond, and an E-rated ESG issuer could issue a high-quality sustainability bond’, Sam Morton adds.
Sustainability-linked bonds: a different layer of complexity
Meanwhile, sustainability-linked bonds (whose proceeds are not allocated to specific projects, but used for general corporate purposes) avoid the issue outlined above, but bring a separate layer of complexity to the table.
For clarification, these are debt instruments whose financial characteristics change depending on whether the issuer achieves predefined sustainability objectives. Often, it is the coupon that will change, increasing by a certain amount each year if the issuer misses its target.
The lack of specificity associated with these bonds leaves investors reliant on the overall ESG credentials of the issuer. They need to decide whether they value the achievement of these KPIs, the financial consequences, and how these will be reported to investors.
Matching risk and reward
The two examples in this article provide just a flavour of the considerations at play. What’s crucial is that investors closely monitor these risks as they evolve.
At Invesco, we believe that having well-resourced and experienced credit and investment teams is crucial to this process. They look to ensure that credit spreads adequately reflect downside risks, with ‘at risk’ names avoided where this is not the case.
