インドのソブリン・グリーンボンド（SGrB）プログラムの最初の3年間を実証的に評価。グリーニアムは不安定で、2024年8月にはマイナス9bpとなり、発行コスト削減効果は限定的。需要も低下し、発行規模は気候資金需要の1%未満。制度的シグナルと市場発展には寄与したと結論。
English
This paper empirically assesses India's Sovereign Green Bond programme over its first three years, finding an inconsistent greenium (negative 9bp by Aug 2024), weakening investor demand, and issuance covering under 1% of annual climate finance needs. It concludes SGrBs serve more as institutional signalling than cost savings, offering recommendations for transparency and scaling.

日本のGX文脈において
日本ではグリーンボンド市場の拡大とトランジション・ファイナンスが課題。インドの実証結果は、グリーニアムの持続性や投資家基盤の重要性を示唆し、日本の発行体や政策担当者にとって示唆に富む。
In the global GX context
This empirical study of India's SGrB programme provides valuable evidence for global green bond scholarship, particularly on greenium dynamics and market development in emerging economies. It informs international discussions on transition finance and sovereign issuance strategies under TCFD/ISSB frameworks.

📄 Abstract（原文）
India's Sovereign Green Bond (SGrB) programme, launched in January 2023, was designed to serve three purposes at once: to lower the government's own cost of borrowing through a pricing discount known as the greenium, to widen the base of climate-conscious investors, and to signal institutional credibility on climate commitments to international markets. This paper offers an empirical, data-grounded assessment of how far the programme has achieved these aims over its first three years of operation, drawing on Reserve Bank of India auction records, market commentary, and a comparative review of four other emerging-market sovereign issuers: Chile, Indonesia, Nigeria, and Poland. The analysis finds that India's greenium has been inconsistent rather than dependable: an early positive differential gave way to a confirmed negative greenium of 9 basis points at the August 2024 auction, meaning the government paid a premium rather than a discount to issue green. Investor demand, measured through subscription ratios, has also weakened over time, from 4.11 times the notified amount at the debut auction to close to parity by mid-2024. Placed alongside Chile, Indonesia, and Nigeria, India's cumulative issuance covers under 1 per cent of its own annual climate finance requirement, a smaller share than Chile's, though larger than Nigeria's. The paper concludes that SGrBs have, so far, functioned more effectively as an instrument of institutional signalling and market development than as a reliable source of cost savings, and it sets out specific, data-supported recommendations for improving reporting transparency, deepening the domestic investor base, and scaling issuance.
