A Lifeline or Sinking Ship in Ocean Conservation? A Deep Dive into Value Creation of “Blue Bonds”

The 2018 issuance of Seychelles’ Debt for Nature blue bond raised new hopes for capital market solutions for conservation. Although there is growing excitement over the potential of blue bonds in channeling much needed investment for ocean conservation, as yet, blue bond uptake remains limited, and existing issuances have been criticized for their vague and unambitious environmental impact. This article analyzes the emergence of blue bonds as a new asset class and seeks to explain its development trend by tracking the processes of value creation, transfer, and distribution of every blue bond instrument issued since 2018 (n = 45). Supported by a mixed-method approach, we challenge the popular conception of blue bonds as a homogeneous asset class and reveal that the market has evolved into three categories: Ocean-based Debt for Nature Bonds, Blue Conservation Bonds, and Blue Economy Bonds. Across the categories, the market struggles to internalize long-term environmental value within bond structures. This article argues that the challenges facing blue bonds originate from the temporal and spatial mismatch between the long-term, dispersed value-delivery for ecosystem recovery and the short-term, structured demands of capital markets. Prevailing calls for improved disclosure cannot address the deeper challenges of aligning financial value accumulation with nature conservation and restoration. We conclude that rather than replicating the green bond market model, a rigorous rethinking of investment structures is necessary to effectively finance ocean conservation at scale.
