Just six metrics can effectively assess sovereign issuers’ sustainability and provide guidance for both issuers and investors.

From a sustainability perspective, investing in sovereign emerging-market (EM) debt can feel messy. Most investors feel just familiar enough with individual EM countries to fall prey to subjective judgments when making comparisons. The market tends to overreact to news—good news, bad news and often both at once. And huge, complex data sets bog down analyses and muddy the view.

That’s why we’ve charted a new path: one that sheds light on sovereign EM investing through a small set of concrete metrics that help identify potential value and provide guidance for both issuers and sustainable investors.

Gauging Sustainability with Precision Metrics

To solve the problems of subjectivity, reactivity and obscurity, we’ve identified six measures by which a sovereign issuer may be ruled in or out of an investable universe of sustainable sovereign debt.

We began with the 17 UN Sustainable Development Goals (SDGs), which we recognize as a blueprint for identifying sustainable investments. Together, these 17 SDGs comprise 169 specific sub-targets. From these, we selected six that represent the broader investment themes of climate, health and empowerment. We believe that these six sub-targets capture the spirit of the larger list. They cover the transition to low-emissions energy consumption; biodiversity; hunger; infant mortality; equal employment opportunities; and institutional strength (Display).

For each of these six sub-targets, we identified a specific measure. For example, to be considered in alignment with UN SDG 3.2 (one of the two health sub-targets), countries should reduce newborn mortality to 12 or fewer deaths per 1,000 live births—a threshold set by the UN. Roughly half of all countries pass this metric.

Applying the Framework to Narrow the Investable Universe

The result is a robust analytical framework anchored in specific UN SDG targets. A country that passes all six metrics qualifies for sustainable EM investing. Countries that fail three or more metrics should not be considered for inclusion in a sustainable investing universe.

In our analysis, countries that fall just short of passing, failing only one or two of the six metrics, deserve a closer look. If we believe we can engage* with the country to improve in that fifth or sixth category, that country may become eligible for inclusion.

Just how rigorous is this methodology? Only about half of all countries pass any single metric. Fewer than 20% of countries globally, including developed markets, pass all six metrics.

Further, thanks to the materiality of the identified metrics over the long run, we believe that countries that pass this framework can deliver better risk and return outcomes over time than those that fail.

Putting the Framework into Practice

Three countries—Chile, Brazil and the Philippines—exemplify the rigor of this framework.

Chile hits the mark by passing all six metrics. The country’s sustainable development is on par with that of many developed countries. For example, from 2010 through 2019, Chile increased wind and solar energy from around 1% to 14% of total electricity. Since 2000, it has increased its forested land by around 15%. It recently met UN goals around lowering preventable infant deaths. And it has a strong female participation rate in the labor force.

Brazil fails one critical metric: deforestation. Since 2000, the country’s forest cover has declined by 10%, due mostly to destruction of the Amazon rainforest. (Almost 20% of the Amazon rainforest has been destroyed since 1970.) In our framework, this signals the need for investors and asset managers such as ourselves to actively engage with Brazil to make needed improvements on this front.

After all, Brazil leads the world in many other sustainability measures: increasing wind and solar from around 0% to 10% of total electricity; meeting the UN threshold on preventable infant deaths; and having a fairly strong labor force participation rate from women.

By contrast, the Philippines fails on three metrics and thus is not yet eligible for inclusion in our sustainable universe, despite having a dynamic economy and an investment-grade rating. From 2010 through 2019, the country increased wind and solar only marginally to just 2% of its electricity matrix. Though the Philippines has worked to reduce preventable infant deaths, at the current rate the country will fail to meet UN goals by 2030. And the labor force participation rate from women is below our threshold.

The Benefits of a Sustainable Framework

Not only is this framework robust, but unlike many existing approaches to defining a sustainable investment universe, our approach is simple, transparent and objective, with data drawn from neutral sources such as the World Bank.

What’s more, our approach positions the investable universe to grow as more countries meet more metrics, because it uses absolute, rather than relative, thresholds. In addition, five of the six metrics are forward-looking, so that we are able to assess not only where a country is now (static measure) but where it is going (dynamic measure). And the approach allows for targeted, effective engagement on material and relevant issues—helping an issuer move the needle from nearly to fully qualified.

Lastly, our framework for sustainable sovereign investing aligns with investor objectives and intentions. Where the goal is to improve sustainable practices around the world, we believe our framework stands out as both effective and credible.
