The Importance of Climate Scenario Analysis in Financial Risk Management

Climate change poses significant risks to global economies and financial stability. However, these risks are complex, uncertain, and difficult to quantify. To address this challenge, financial institutions and central banks increasingly rely on climate scenario analysis, a tool designed to assess potential future economic and financial risks based on different climate policy, technology, and economic pathways.

The Network for Greening the Financial System (NGFS) has developed climate scenarios that help central banks, supervisors, and financial institutions understand climate-related risks. These scenarios are crucial for long-term planning and decision-making, ensuring financial systems remain resilient amid a changing climate.

Why Climate Scenarios Matter

1. Understanding Transition and Physical Risks

Climate scenarios provide a framework for understanding the two primary categories of climate risks:

• Transition risks: Risks associated with shifting to a low-carbon economy, including policy changes, technology shifts, and changes in consumer behavior.

• Physical risks: Risks resulting from the direct impact of climate change, such as extreme weather events (e.g., hurricanes, floods, heatwaves) and long-term shifts in climate patterns.

By analyzing multiple climate scenarios, financial institutions can anticipate risks and opportunities arising from both transition and physical risks.

2. Supporting Financial Stability and Economic Resilience

Financial regulators, such as central banks and supervisors, use climate scenario analysis to:

• Assess potential disruptions to the financial system.

• Guide policy measures that mitigate financial instability due to climate risks.

• Ensure banks and financial institutions are prepared for climate-related shocks.

3. Aligning with International Climate Goals

Climate scenario analysis helps align banking and investment strategies with global sustainability goals, such as:

• The Paris Agreement, which aims to keep global temperature rise below 2°C.

• Net-zero commitments by 2050.

By integrating scenario analysis into financial planning, institutions can proactively manage risks rather than react to crises.

How NGFS Scenarios Work

The NGFS Climate Scenarios provide a structured way to analyze possible climate-related financial impacts. They cover different pathways, ranging from orderly transitions to hot house world scenarios where little action is taken, leading to severe physical risks.

NGFS Scenario Categories

1. Orderly Transition Scenarios

• Climate policies are implemented early and consistently.

• Transition risks are moderate, and physical risks are minimized.

• Example: Net Zero 2050 scenario, which limits global warming to 1.5°C.

2. Disorderly Transition Scenarios

• Policies are delayed or inconsistent, increasing transition risks.

• Higher economic costs due to abrupt policy shifts.

• Example: Delayed Transition scenario, where action is taken late, causing economic and financial shocks.

3. Hot House World Scenarios

• Minimal climate action leads to severe physical risks.

• Rising temperatures cause economic losses and social disruptions.

• Example: Too-Little-Too-Late scenario, where delayed and weak policy action fails to prevent extreme climate events.
