As impact investing continues to grow — and into a nearly $9 trillion market, at that — many investors still remain focused on the equity side of their portfolios when it comes to aligning their holdings with their values.

That doesn’t mean there aren’t opportunities for investors to be impactful with their fixed-income capital, as well. Private debt currently comprises more than 40 percent of the capital in the impact investing market, according to the Global Impact Investing Network.

Of course, not every investor has access to private debt markets, but mounting interest in impact investments across all allocations has created more accessible options for investors.

“No sectors or businesses grow without leverage,” said Gil Crawford, CEO of MicroVest. “I think there was so much buzz around the high-tech side of impact investing, and those investors, almost by their nature, are not sensitized to the important role that debt plays in growing not only companies but also entire economies.”

Lining up investments, values

The first step for impact investors, regardless of asset class, is to think about which issues or causes are important to them so that they can craft an investment strategy that’s in line with their values.

“If you’re looking at traditional corporate bonds, then instead of investing in a company totally based on its credit rating, you can also incorporate ESG [environmental, social and governance] into your screens,” said Avi Deutsch, principal at Vodia Capital. “That makes sense for a lot of reasons.

“We think that ESG ratings are a great way to reduce earnings volatility, and there’s a growing body of research that directs this.”

There’s also significant research that shows sustainable investing doesn’t mean sacrificing returns. It’s possible to invest responsibly and make a profit on your investments. A recent Barclays studyfound that bond portfolios comprised of investments with high ESG scores outperformed the index, while those with lower scores underperformed.

In addition to third-party ratings, companies themselves have become far more transparent about their practices following demand from both investors and the public at large. Last year 85 percent of companies published a sustainability or corporate responsibility report — up from just 20 percent of companies who did so in 2011, according to the Governance & Accountability Institute. So once investors have narrowed down their universe of industries, they can screen individual companies on granular data while looking for ways to diversify their fixed-income holdings.

Investors who’d prefer to buy bond funds rather than hold individual bonds also have options. The number of funds with ESG criteria has grown by 29 percent per year since 2010.

“As the demand for impact investing grows, especially among mainstream and retail investors, fund managers are starting to develop new products that reach new audiences,” said Abhilash Mudaliar, research director at the Global Impact Investors Network. “So we’ve seen significant growth on the public side, and we expect that to continue going forward.”

Other options

Another option for fixed-income investors looking to make an impact are green bonds. Issued both governments, organizations or corporations to fund specific, sustainable projects that adhere to specific environmentally focused projects, green bonds not only promise to meet their debt obligations according to the bond, but aim to do so while adhering to specific sustainability commitments.

Green bonds have grown so much since their launch a decade ago that they’ve become fairly liquid and easy to trade. Global issuance of green bonds in 2017 reached $155.5 billion, an 87 percent increase over 2016, according to the Climate Bonds Initiative.

“What’s happening now, at this stage of the game, is you’re starting to get a more coherent definition of what a green bond is, and there are some new product offerings,” said George Gay, CEO of First Affirmative Financial Network. “There are some green bond ETFs now, where there weren’t any two years ago.”

Following on the success of green bonds, issuers have begun to bring to market SDG bonds, aligned to one or more of the United Nations Sustainable Development Goals. While SDG bonds remains a relatively niche market for now, many consider it poised for growth.

“The development of SDG bonds could really open up the market for fixed income,” said Gavin Power, a chief of sustainable development and international affairs at Pimco. “The 15-year time horizon for the SDG goals and the project orientation of the bonds creates a lot of opportunity.”
