日本語
本論文は、NGFSシナリオを用いた生存分析により、欧州3カ国（ベルギー、イタリア、ポルトガル）の中小企業向け証券化ローン（約390万件）の将来デフォルト確率を2050年まで推計。厳格な気候政策が短期的にデフォルトリスクを高める一方、ネットゼロ2050移行は長期的に便益をもたらすことを示した。また、政策の遅れや断片化に伴う不確実性が信用リスクの追加要因となることを指摘。
English
This paper uses NGFS scenarios in a survival analysis framework to project forward-looking PDs for 3.9 million SME securitised loans in Belgium, Italy, and Portugal up to 2050. Results show short-term PD increases under stringent climate policies but long-term benefits under Net Zero 2050 transition. Delayed or fragmented policies create business-confidence shocks adding credit risk.

📝 gxceed 編集解説 — Why this matters
日本のGX文脈において
日本でも金融庁が気候変動ストレステストの導入を模索しており、本論文の手法（生存分析＋NGFSシナリオ）は中小企業向け融資のリスク評価に応用可能。特に、政策の遅れが信用リスクを増幅する点は、日本のGX政策の進捗に示唆を与える。
In the global GX context
This paper provides a rigorous empirical framework for climate stress testing on SME loans, directly applicable to global disclosure and risk management practices. It complements TCFD/ISSB guidance by quantifying forward-looking credit risk under different NGFS pathways, highlighting the trade-offs between short-term policy costs and long-term transition benefits. Particularly relevant for banks and regulators developing climate scenario analysis.
👥 読者別の含意
🔬研究者:Survival analysis with NGFS scenarios offers a replicable method for SME credit risk modeling under climate uncertainty.
🏢実務担当者:Banks can use the framework to assess climate risk in SME loan portfolios and align with disclosure requirements.
🏛政策担当者:Highlights that delayed climate policy creates additional credit risk via business confidence shocks, urging timely action.
📄 Abstract（原文）
ABSTRACT Assessing the future impact of climate risks on the probability of default (PD) of small and medium enterprises (SMEs) is challenging due to limited disclosure, policy uncertainty and exposure to physical risks. This paper addresses this gap by integrating macroeconomic variables from the Network for Greening the Financial System (NGFS) scenarios into a survival analysis framework to project forward‐looking PDs for SME securitised loans up to 2050. The analysis is based on a comprehensive dataset of 3.9 million SME securitised loans observed between 2013 and 2022 across Belgium, Italy and Portugal. The results show that climate risks increase projected SME PDs in the short term relative to a baseline, particularly under scenarios with rapid and stringent climate policy action. In the long term, the Net Zero 2050 transition generates cobenefits, with PDs falling below those projected under alternative scenarios, while insufficient mitigation increases portfolio risk from physical climate impacts. The findings also highlight that a business‐confidence shock, driven by uncertainty about delayed or fragmented climate policies, can represent an additional source of credit risk.
