本研究は、2017年から2025年までのデータを用いて、グリーンフィンテックとエネルギー資産のポートフォリオを最適化し、ヘッジ比率戦略が最も高い累積リターンをもたらすことを示した。特に、炭素排出先物と太陽エネルギー資産でヘッジする場合に有効である。また、COVID-19や地政学的緊張などの不確実性が高い時期には、リスクの波及が増大し、分散効果が低下することも明らかにした。
English
This study optimizes a portfolio of green fintech and energy assets using data from 2017 to 2025, finding that a hedge-ratio strategy yields the highest cumulative returns, especially when hedging green fintech with carbon futures and solar assets. It also shows that during high uncertainty periods like COVID-19 and geopolitical tensions, risk spillovers increase, reducing diversification benefits.

📄 Abstract（原文）
The convergence of financial technology (Fintech) and climate change has resulted in a new wave of "green Fintech," a sector dedicated to supporting environmentally sustainable innovation in financial services. Our research shows significant growth of green Fintech from August 2019 to February 2020 and from May 2020 to September 2022, driven by global disruptions such as COVID-19, geopolitical tensions, and crypto-bank failures. Using the DCC-GARCH t-Copula model and causal impact analysis, we optimize a portfolio of green Fintech and energy sector assets from January 1, 2017, to September 27, 2025. Our results reveal strong correlations, underscoring green Fintech's potential to attract capital for clean energy development. Portfolio analysis shows that while dynamic portfolio weights and buy-and-hold strategies provide relatively stable returns, the hedge-ratio strategy delivers the highest cumulative returns, especially when green Fintech is hedged with carbon-emission futures and solar-energy assets. However, during periods of extreme uncertainty, such as the COVID-19 pandemic and the Russia–Ukraine conflict, risk spillovers between energy markets and green Fintech increase significantly, reducing the effectiveness of diversification strategies. This evidence serves as a critical resource for policymakers in designing regulatory and strategic tools to promote resilient, low-risk green financial systems.
