Investor Banking & ESG: What’s Changing
Investment banking clients and advisors are no longer treating ESG and sustainability themes as boutique or compliance topics—they’re central to valuation, risk assessment, and deal attractiveness. According to S&P Global’s “Investment Banking” offering page, material themes such as climate risk and other ESG factors are now integral when aligning strategies, especially in environments moving toward a low-carbon and equitable future.

A core shift is rising demand for quantified and granular data—asset-level climate risk exposure, physical hazards, carbon transition impact, benchmarks, and reporting aligned with frameworks like TCFD. For example, S&P Global Sustainable1 research estimates that most large companies will have assets with high exposure to physical climate hazards by mid-century—and that value‐at‐risk metrics for physical damage could be significant.

S&P Global’s Strategic Moves
To meet this demand, S&P Global is bolstering its data and product stack. Its acquisition of With Intelligence for $1.8 billion adds private markets intelligence, expanding its flight into alt-datasets used by LPs, GPs, advisors; this scales its margin-generating business in high-growth adjacencies.

On the corporate strategy side, the Investor Day 2025 presentation laid out targets: organic constant-currency revenue growth in the 7–9% range overall, with operating margin expansion of 50–75 bps, and double-digit EPS growth. Division-level targets include 6–8% growth for Market Intelligence and Energy, 10–12% for S&P Dow Jones Indices. ESG and AI are cross-cutting enablers.

Implications for Investment Banks
1. Due diligence and valuation models must increasingly include ESG metrics (physical risk exposure, carbon regulation scenarios etc.), not just financials and operations.
2. Data and ESG scoring providers are becoming strategic partners—banks may choose providers not only for data quality but for integration, scenario forecasting, and AI capabilities.
3. M&A/financing will attach premium or risk discounts based on ESG characteristics, leading to a differentiated cost of capital depending on climate exposure.
4. Regulatory and reporting risks are mounting; investors and counterparties expect transparency, science-based targets, and meaningful metrics.
Open Questions & Risks
- How will various regulatory regimes (EU, U.S., Asia) converge or diverge in ESG disclosure standards, and how will that affect cross-border investment banking?
- What are the accuracy, provenance, and potential bias in physical risk projections, ESG scores, and climate scenario models used in transactions?
- To what extent will rising costs or complexity of ESG integration affect smaller or mid-tier banks compared to bulge-brackets?
- How will market participants respond if ESG becomes too commoditized or if there’s ESG fatigue from investors demanding less tangible impact?
