Meaningful Reward for Performance

The promise of outcome-based finance is that capital markets will reward company performance on SDG targets and promote competition for the most effective sustainability solutions. In the long run, as investors continue to improve their understanding of how sustainability impacts financial analysis, the efficient market theory suggests that markets will “price” sustainability performance in the market for corporate bonds and equity. In the meantime, step-ups in the interest rates have been introduced to ensure that companies are sufficiently incentivized to meet their targets.

The credibility of an issuer’s commitment is enhanced by detailing the intermediate steps that will allow the issuer to get to the goal: what specific deliverables will be met and what the medium- to long-term goals are.

Arbitrage in the Secondary Market

Over time, bond (and equity) prices on the secondary market should reflect performance on material SDG targets. With the right incentives and information and the participation of all actors in the investment value chain, the bond market should reward performance key SDG metrics, just as it rewards performance on key business or financial metrics. If a company performs in line with its SDG targets, pricing would be in line with its credit rating. Higher performance would lead to higher bond prices and lower yield; under performance would lead to lower bond prices and higher yield.

Without adjustment mechanisms in the financial product itself, performance on SDG targets would not immediately impact the cost of a company’s outstanding debt. However, it would impact the cost of refinancing that debt or obtaining new financing.

The entire investment value chain, including accountants, financial analysis, and credit rating agencies, must play the role of benchmarking and rewarding performance.

The Use of Step-Up and Step-Down

Most sustainability-linked bonds and loans include a step-up mechanism in which interest rates increase if the issuing company fails to meet its SDG targets. While this feature has helped the rapid growth of outcome-based finance, the long-term growth and credibility of the market will require a meaningful variation in the financial characteristics of these instruments, likely beyond the current average of 34 basis points (see figure below).

Step-down and other structural adjustments have also been introduced. However, they are much less popular, especially in the bond market where the simplicity and standardization of instruments is critical.

Issuers should be cautious with this type of mechanism, especially concerning the nature of the targets they set for the financial instrument: if an issuer gets a step-up, it will affect the company negatively because the market will see it as a nonperforming company that is not meeting its commitments.

The market for sustainability-linked financial instruments is still new, and structures that are too complex might erode investor confidence.
