Periods of market volatility often reveal which companies are best equipped to withstand uncertainty. A new study from Morningstar Sustainalytics finds that firms with lower environmental, social, and governance (ESG) risk ratings show greater financial resilience, outperforming peers with higher ESG risk—especially during turbulent economic events.
The research, published in mid-2025, examines over six years of market performance from January 2019 to April 2025. This era was defined by three major episodes of market stress: the COVID-19 pandemic, the Russia-Ukraine war, and the introduction of new U.S. tariffs. Across these shocks, Sustainalytics analysts observed that companies with well-managed ESG exposure generally delivered stronger risk-adjusted returns.ESG Risk as a Financial Signal
Morningstar Sustainalytics’ ESG Risk Rating quantifies a company’s exposure to financially material ESG factors and its ability to manage them. Scores range from Negligible (strong risk management) to Severe (major unmanaged risks). The study organized more than 1,500 publicly traded U.S. companies into five portfolios along this spectrum.
The results were telling: each five-point decrease in ESG risk score correlated with roughly a 1% increase in annual excess returns—a modest but persistent financial advantage. Firms categorized as Low ESG Risk exhibited lower volatility and stronger long-term performance than those rated High or Severe.
What’s more, the study shows that ESG risk ratings can complement traditional risk metrics by capturing sustainability-related risks that are not fully reflected in volatility measures, suggesting they can serve as an additional financial risk indicator rather than just a moral or reputational measure.
Resiliency through Turbulence
During the global pandemic in 2020, Sustainalytics found that companies with lower ESG risk generally outperformed their higher-risk peers, likely due to more robust governance, stronger stakeholder relationships, and greater operational flexibility.
This aligns with a broader trend: institutional investors increasingly turned to sustainability frameworks to manage downside exposure during an uncertain outlook.
The pattern shifted temporarily during early 2022. As energy markets convulsed in response to conflict and sanctions, fossil fuel-exposed companies—often with higher ESG risk ratings—enjoyed unusually high short-term returns.
However, Sustainalytics analysts caution that this was a temporary anomaly. Over the longer term, these same high-risk firms suffered greater volatility and underperformed on key financial indicators once energy prices normalized, reinforcing the case for focusing on cleaner, forward-looking sectors. The takeaway: short-term market distortions can reward unsustainable practices, but over time, effective ESG risk management still wins.
When the U.S. introduced a new round of tariffs in 2025, investors again favored firms with lower ESG risk profiles, viewing them as better equipped to handle shifting trade conditions, regulatory scrutiny, and supply chain complexity. This mirrors earlier research suggesting that companies with mature ESG policies often demonstrate stronger adaptability to new regulations and global supply disruptions.
By the end of the study period, the cumulative trend was clear: companies managing ESG risk effectively tended to preserve financial performance and stability across diverse market stress events.
What This Means for Investors
For individual and institutional investors alike, this study reinforces the case for ESG integration—not as a tradeoff between ethics and returns, but as a risk management strategy.
While the performance premium for lower ESG risk may appear small, its importance compounds over years and through volatile markets. Investors seeking long-term stability—especially during uncertain times—may benefit from prioritizing companies that proactively manage environmental impact, treat workers and stakeholders responsibly, and uphold transparent governance practices.
As Sustainalytics’ findings put it, incorporating ESG risk into investment analysis “supports the alignment of sustainability goals with effective risk management, while also contributing to the preservation of financial performance.”
Moving Forward
The idea that doing good might also mean doing well financially has now gained robust empirical support. Whether you’re an engineer, educator, or business professional seeking to grow wealth responsibly, the data continue to show that sustainable investing isn’t charity—it’s strategy.
