New Research Finds Untapped Opportunity for Impact and Returns in Fixed Income
Research collaboration between Builders Vision, Tideline and BlueMark highlights the impact of fixed income investments
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.

Fixed income can deliver steady returns, reliable cash flows – and impact at scale
Critical and widely recognized social and environmental challenges, such as broadening access to economic opportunities and strengthening climate resilience, require bold, often capital-intensive solutions.
The price tags far exceed the current reach of the impact investing market.
For example, reaching the Sustainable Development Goals requires investments of $6 trillion annually in areas like facilitating universal access to digital resources, curbing pollution, and transitioning to sustainable food systems. That’s four times the total assets currently allocated to impact.

Are fund managers ready to set targets to hold themselves accountable for impact?
In the early days of impact investing, some investors would make the case for setting impact targets. You can’t manage what you don’t measure, they argued.
The not-always explicit response: Yes, and you can’t be held accountable for what you never promised. The latest Making the Mark report from the impact verification firm BlueMark found that only 42% of clients set impact performance targets as a condition of their investments. A larger number, 58%, work with portfolio companies to set targets after investments are made.
