Double materiality has established itself as a guiding framework for climate‑oriented financial policy. It is useful, but remains too vague to steer mandates, instruments and risks unambiguously. More precise delineations are needed so regulation acts coherently and systemic vulnerabilities are not overlooked.
What double materiality means
The approach covers two perspectives: financial materiality assesses how climate risks affect a company’s financial position. Impact materiality looks at how corporate activities affect the climate and society. In this way the concept addresses both investor and environmental perspectives.
Benefits — and limits
Double materiality creates a common language for authorities, companies and investors. In practice, however, it remains too broad: different policy purposes and risk channels are grouped under a single term. Financial policy actors pursue different mandates — from financial stability through market integrity and consumer protection to price stability — and each requires different information. Without clear allocation, signals can conflict and regulatory gaps may emerge.
Keeping systemic interactions in view
Climate risks operate across several layers: physical risks (storms, floods, heat) affect assets and supply chains. Transition risks (policy, technology) change valuations, sectors and capital flows. Liability risks can lead to lawsuits and payments. These direct effects are amplified via indirect channels: write‑downs trigger fire sales, information gaps increase uncertainty and volatility, balance‑sheet effects dampen credit and insurance supply. Thus systemic risks arise that exceed the sum of individual exposures.
Mandates, instruments and trade‑offs
Materiality is mandate‑dependent: central banks with a price‑stability remit focus on macroeconomic shocks and their effect on inflation and output. Prudential supervisors target liquidity and solvency risks of institutions. Securities regulators ensure transparency for capital‑market participants. Climate mitigation goals often sit with finance ministries or specialized climate agencies. Without clear division of labor, regulation can secure short‑term stability but hinder the transition — or conversely trigger shifts into bank balance sheets.
What needs to be clarified politically
– Explicit allocation: Authorities must state which dimension of materiality they address and which indicators apply. That creates clarity about objectives and responsibilities. – Measurability and thresholds: Materiality requires quantifiable metrics — for example stress scenarios, thresholds for value declines or climate exposure balance sheets. Only then can achievement of goals and policy effects be assessed. – Scenario and stress tests: Forward‑looking tests should link physical and transition risks to capital and liquidity positions. System‑level tests must take interbank linkages and market channels into account. – Better disclosure: Standardized, reliable data on emissions, risk positions and scenarios reduce information asymmetries and improve decision‑making. – Coordination mechanisms: Formalized cooperation between central banks, supervisors, finance ministries and climate agencies reduces objective conflicts. Responsibilities, escalation paths and common assessment bases should be bindingly defined. – Impact‑oriented choice of instruments: Macroprudential tools serve system stability, microprudential tools protect institutions, market rules ensure transparency, and climate‑oriented incentives steer capital flows. Selection should follow clearly justified objectives.
Research gaps and practical testing
Unclear allocations obscure empirical gaps: How strong are cross‑sectoral feedbacks? What role do valuations and market structures play in systemic shocks? Robust evaluations are missing, for example on the effects of particular disclosure requirements on capital flows. Better data, cross‑sector models and tests of real instruments are required.
Why precision matters now
The windows for an orderly adjustment of the financial system are limited. Vague concepts produce inconsistencies, unsettle markets and encourage regulatory arbitrage. Precise definitions of double materiality help clarify responsibilities, choose instruments appropriately and avoid unintended side effects — so that financial markets can support the climate transition in a manageable way.
