Consultation Paper - A Green Investment Discount for Life Insurer Capital Requirements (October 2020)

Introduction

The Prudential Regulation Authority (PRA) is consulting on a proposed discount to life insurers’ capital requirements for investments that meet specific environmental criteria. This consultation paper outlines the rationale, proposed framework, and expected impact of the Green Investment Discount.

Background

Life insurers play a critical role in long-term financing and capital markets. Aligning capital requirements with sustainable investment practices supports the transition to a low-carbon economy while maintaining prudential standards. The proposed discount aims to incentivize green investments without compromising financial resilience.

The Green Investment Discount

The discount applies to life insurers’ regulatory capital calculations for assets that satisfy defined environmental, social, and governance (ESG) criteria. Eligible investments will receive a reduced risk weight or capital charge, reflecting their lower long-term systemic risk and alignment with national climate objectives. The framework specifies qualifying asset classes, verification mechanisms, and reporting obligations.

Impact Assessment

The PRA has conducted an initial impact assessment to evaluate the economic, financial, and operational effects of the discount. Analysis suggests a moderate reduction in aggregate capital requirements for participating life insurers, with minimal impact on policyholder protection or market stability. The assessment also considers potential risks, including greenwashing, data availability, and market distortion.

Consultation Questions

The PRA invites feedback on the following key areas:

• The scope and definition of qualifying green investments.
• The appropriate magnitude of the capital discount.
• Verification, monitoring, and reporting requirements.
• The implementation timeline and transitional arrangements.
• Potential interactions with existing ESG disclosure frameworks.

Next Steps

Responses to this consultation are requested by the specified deadline. The PRA will review all submissions, conduct further analysis, and publish a policy statement detailing the final rules. Stakeholders will be notified of the publication date and implementation schedule.
