This report examines the tightening of bond ESG premiums, or greenium, and its impact on sustainable spreads leading into 2026.

According to recent forecasts, the global green bond market is projected to reach $1.5 trillion by 2025, driven by increasing regulatory support and investor appetite. Countries with robust ESG frameworks, like the U.S., EU, and Germany, are likely to see the most significant growth.

With nearly $1 trillion in sustainable bond issuances in 2023 alone, the trend towards sustainable finance is poised to reshape the global bond market landscape.
