MainStreet Partners’ July 2025 GSS Bonds Market Trends Report shows a 13% year-on-year drop in global Green, Social, and Sustainability (GSS) bond issuance in the first half of 2025, down to $495 billion. Still, Q2 issuance held steady at $250 billion, matching the same quarter last year.

Market sentiment remained cautious amid inflation, trade uncertainty, and geopolitical tension. Yet Green Bonds stayed dominant, especially in the UK, where issuance rose by 10% to $14.7 billion. Financial institutions led the UK market, accounting for 64% of issuances, nearly double the global average.

Sustainability and Social Bond volumes held firm at $131 billion and $82 billion, respectively. However, Sustainability-Linked Bonds saw their weakest first-half on record, at just $421 million.
