In this episode, Kate Webber, Chief Solutions & Technology Officer at the PRI, is joined by Malea Figgins, Vice President at TCW, and David Klausner, ESG Specialist at PGIM Public & Private Fixed Income, to explore how responsible investment is being applied in securitised debt markets.

Focusing on residential and commercial mortgage-backed securities (RMBS and CMBS), as well as emerging asset classes such as data centres, the discussion draws on insights from the PRI’s Technical guide to Responsible Investment in securitised debt. Together, the guests unpack how environmental, social and governance risks and impacts are assessed in practice, where data gaps remain, and why securitised assets are central to financing the real economy.

Overview

Securitised debt is a core component of global fixed income markets, representing around US$14 trillion in outstanding issuance. By pooling underlying loans, such as home mortgages, commercial property loans or consumer credit, securitisation channels capital into housing, infrastructure and other real-economy assets.

Despite its scale and relevance, securitised debt has historically been underrepresented in responsible investment discussions. This episode explains why environmental, social and governance considerations are not peripheral, but fundamental to credit analysis in this asset class, particularly given its exposure to consumers, real assets and climate risk.

Detailed coverage

Why securitised debt matters for responsible investors

Malea and David explain how securitisation directly touches everyday assets, from homes and cars to student loans and commercial buildings. They argue that social risks such as predatory lending, affordability and loan servicing quality, alongside environmental risks like climate events and insurance availability, are core credit risks in these markets.

Risk versus impact

David outlines the importance of distinguishing between environmental, social & governance risk (financially material factors affecting credit quality) and impact (how investments affect society and the environment). The risks are integrated into bottom-up credit analysis across all portfolios, while impact overlays are applied where client mandates explicitly require them.

Embedding sustainability in RMBS and CMBS analysis

Malea discusses how sustainability considerations already align with credit fundamentals in many cases. In commercial real estate, green building certifications, energy efficiency and lower operating costs can support stronger net operating income and tenant stability. In residential markets, affordability metrics and borrower characteristics play a key role.

Case study: data centres and climate risk

The episode explores the rapid growth of securitised data centre financing, driven by AI and digital infrastructure demand. David shares an example where climate-related insurance coverage and extreme weather risk directly influenced internal credit ratings, illustrating how environmental risks can be central, not secondary, to investment decisions.

Private markets and improving data quality

Both guests highlight how private asset-backed finance allows earlier engagement with issuers, creating opportunities to improve environmental and social data collection. Lessons from private markets may help drive better disclosure and transparency in public securitised markets over time.

Labelled bonds and greenwashing risks

Malea cautions that not all labelled securitised bonds are created equal. The discussion stresses the need for rigorous due diligence on use-of-proceeds and frameworks, with internal guardrails to avoid low-quality or misleading labelled issuance.
