Ethical investments have never been hotter. Assets under management in all investment strategies governed by ESG principles grew more last year than in the preceding decade.
While many investors will be familiar with the $1trn green bonds market, issuance of other debt securities designed around ESG considerations has been gathering pace.
For example, new social bond issues totalled $165bn in 2020, up from $18bn in 2019. Sustainability bond issuance hit $75bn in 2020, from $43bn a year earlier. Sales of both instruments are on track to more than double this year, according to Bloomberg data.

Much of this activity can be attributed to a combination of regulatory pressure, rising corporate awareness and investor demand. The popularity of this investment theme has also been boosted by growing awareness of the social problems that have worsened during the pandemic.
While we applaud the amazing speed of this growth, we’re also concerned. When markets move this far this quickly, inevitably some corners end up being cut. We see a risk that money will flow into investments whose ESG credentials don’t stand up to closer scrutiny.
Take the growing popularity of sustainability-linked bonds (SLBs). SLBs allow borrowers to set a sustainability target, while committing to pay a penalty if they fail to achieve that target.
Investors are attracted to them because issuers are tied to specific outcomes rather than a simple expenditure goal. This, in theory, more closely aligns the interests of borrowers with those of investors who want a clearer idea of the positive effects of their capital.
Bank of America expects global SLB issuance to hit some $100bn by year-end. This is extraordinary considering this market only started last year, and just $9.5bn of SLBs were issued in the first quarter of this one.
Although this is global data, we’ve also seen SLB issuance grow with the same momentum in Asia. What’s more, European markets will likely be fertile ground given the region’s history at the forefront of developments in responsible investing.
What’s the problem?
Financial instruments that are marketed with an ESG label often come with a second-party opinion from a ESG ratings agency, such as Sustainalytics or Vigeo Eiris. This is to ensure alignment with a recognised framework – for SLBs this would be the International Capital Market Association’s SLB principles. This framework contains five components:
- Selection of key performance indicators (KPIs)
- Calibration of sustainability performance targets (SPTs)
- Bond characteristics
The framework states that SPTs should be ‘ambitious’ and ‘beyond a business as usual trajectory’. It also requires that variation from original terms should be ‘meaningful’.
Unfortunately, these requirements are qualitative. So far, second-party opinion providers have been unable to establish requirements that are quantifiable. In particular, the issue of ‘meaningful’ variation has been problematic.

For example, all but one of the US dollar-denominated SLBs issued this year feature a penalty of less than 10% of the original coupon rate. Nearly half of these SLBs have a variation of less than 5% of the original coupon rate.
In several cases, the coupon variation, or step-up, only applies to the final year of the SLB’s life, making the present-value impact of the potential financial cost even less significant.
What’s more, there are other examples where the measurement of KPIs and financial costs coincide with times when the bonds are callable. This gives the issuer an option to redeem the bonds early and avoid paying a financial penalty.
What should investors do?
Bottom-up assessment of issuers and the specific features of individual SLBs, is critical. Investors need to be more discerning, not skimp on due diligence, and speak out whenever they find something that needs addressing. They need to ask themselves whether an issuer is undertaking substantive changes to transform its business. Is it benefiting from the retirement of aging assets to meet its KPIs? Are the costs of failing to meet SPTs significant, immaterial, or can they be avoided?
Investors can also push issuers to improve the quality of SLB issuance by demanding:
- That KPIs are assessed on multiple dates that span most, if not all, of a bond’s life;
- Greater use of milestones to track progress on meeting KPIs over time;
- Financial penalties that reflect a higher proportion of the original borrowing cost;
- Call features don’t allow issuers to circumvent the costs of failing to meet KPIs.
Being a good ESG bond investor involves more than reading what’s written on the tin.
