Despite its status as the world’s largest asset class, fixed income is rarely thought of as a vehicle for social or environmental impact. A new research collaboration between Builders Vision, Tideline and BlueMark presents impact investing in fixed income (or “impact fixed income”) as an accessible and attractive means of generating positive impacts for people and the planet, without any financial trade-off. 

The authors of a new paper, “Scaling Solutions: The Fixed Income Opportunity Hiding in Plain Sight,” argue that impact fixed income is a rapidly growing asset class with predictable and comparable financial returns to traditional fixed income investments. The authors also found that interested investors can navigate this new asset class using existing impact investing concepts, frameworks, and standards. The full paper, along with practical resources for institutional asset owners, is available at www.tideline.com/impact-fixed-income

According to the research, there are several features of the fixed income asset class that make it ideally suited for impact, including its:

There is also evidence of strong demand for an impact approach within fixed income.

Taken together, these data points signal the importance of establishing a shared understanding of best practices within impact fixed income as well as providing a roadmap that investors can use to better define and refine their approaches.

Taxonomy of impact fixed income

The impact fixed income market benefits from a strong infrastructure that enables investors to confidently balance profit and purpose. A bond labeling regime defines what meaningful and authentic impact looks like at the issuance level, supported by voluntary standards such as International Capital Markets Association’s (ICMA) green, social, and sustainability (GSS) bond principles and the European Union’s (EU) Green Bond Standard. There are also fund labeling regimes in the EU (Sustainable Finance Disclosure Regulation) and UK (Sustainability Disclosure Requirements) that are intended to address greenwashing concerns and differentiate between a range of sustainability objectives.

Building on these frameworks, the research paper proposes a new taxonomy for impact fixed income strategies to make it easier for investors to define and categorize their approach.

In stressing the urgency of activating the fixed income market for impact, the report also offers several practical resources for institutional asset owners. These include six in-depth case studies of leading asset managers’ approaches to impact fixed income – featuring Community Capital Management (CCM), EdenTree, Nuveen, Schroders, T. Rowe Price, and Wellington Management – as well as a series of actionable resources that allocators can use to scale up investments in impact fixed income now.

Noelle Laing, CIO of Builders Vision: “For many allocators and asset managers, the connection between bonds and investing in resilience remains opaque. The perception persists that fixed income is solely an asset class for risk mitigation and yield; it’s not solutions-oriented. Yet fixed income has always been the asset class of choice for scaling and sustaining proven projects, products and services — or, in other words, solutions you can count on. Fixed income is not only good for diversification, its steadfastness, and its predictability. It has the attributes that make the asset class an ideal anchor for any portfolio investing to build a future that’s resilient and prosperous.” 

Ben Thornley, Managing Partner and Co-Founder of Tideline: “The overlooked opportunity in impact fixed income is so significant that, once unlocked, it could double or even triple the current size of the impact investing industry. We believe the key to harnessing this multiplier growth is twofold: first, elevating fixed income’s unique attributes as a driver of impact; and second, showing asset owners that impact opportunities in the asset class are readily available, if not already part of their portfolios.”

Sarah Gelfand, President of BlueMark: “Our assessments of how fixed income investors approach impact investing shows a high degree of alignment with existing industry frameworks and standards. This suggests that these long-standing impact investing concepts can support the institutionalization of impact fixed income, enabling investors to rapidly scale up their allocations with confidence.”
