Sustainable debt issuance on track to top $2.5T in 2026, a record

The headline number matters less than its composition: a 5% annual increase is modest for a market that has repeatedly been billed as exponential, suggesting sustainable debt is maturing into a steady, rate-sensitive slice of primary supply rather than a novelty. That shift favors issuers with established frameworks and repeat programs, and it ties the asset class more tightly to the broader rates cycle than to any single thematic catalyst. Whether the record is driven by green, social or sustainability labels — and whether the pace holds once the year closes — is the open question.
