Investing in the Blue Economy: Harnessing the High Seas Treaty for Sustainable Growth

The ratification of the Agreement under the United Nations Convention on the Law of the Sea on the Conservation and Sustainable Use of Marine Biological Diversity of Areas Beyond National Jurisdiction (BBNJ Agreement), or High Seas Treaty, marks a pivotal shift in global ocean governance. Finalized in 2023 and entering into force in January 2026 after reaching 60 ratifications by September 2025, this treaty creates a legally binding framework to protect biodiversity in international waters, which cover 50% of Earth's surface HISTORIC MILESTONE FOR GLOBAL OCEAN PROTECTION: 60th Ratification Triggers Entry into Force of High Seas Treaty^[1]. For investors, it represents not just a regulatory milestone but a catalyst for new markets in sustainable ocean technologies and infrastructure.

Regulatory Tailwinds and Market Opportunities

The High Seas Treaty's provisions—such as the establishment of marine protected areas (MPAs), mandatory environmental impact assessments, and technology transfer mechanisms—directly address systemic risks in the blue economy, such as overfishing, deep-sea mining, and climate-driven ecosystem degradation A high seas treaty protecting vulnerable oceans is ratified | AP News^[2]. These measures reduce regulatory uncertainty, making ocean-based projects more attractive to capital. For instance, the treaty's emphasis on equitable benefit-sharing of marine genetic resources has spurred collaboration between developed and developing nations, opening avenues for joint ventures in biotechnology and pharmaceuticals derived from marine life New High Seas Treaty Prepares International Community for Sustainable and Equitable Blue Economy^[3].

A key driver of investment is the treaty's focus on capacity-building. Articles 40–46 mandate technology transfer to developing countries, ensuring they can participate in high-seas conservation and sustainable resource use A turning point for ocean protection: The High Seas Treaty^[4]. This has already spurred initiatives like the EU's High Ambition Coalition and the Global Ocean Programme, which provide funding and technical expertise to implement MPAs and monitor biodiversity The High Seas Treaty: Prospects and challenges^[5].

Emerging Sectors and Capital Flows

The blue economy is expanding at 0.37% annually, with over 190 startups and 1,300 companies raising an average of $47 million per funding round in 2025 Marine Economy Report 2025: Market Insights and Innovations^[7]. Innovations like underwater drones, satellite-based enforcement systems, and offshore wind farms are gaining traction, supported by $10 billion in ocean-related deals announced at a U.N. conference in 2025 Investors want clear ocean management rules to scale up funding^[8]. While this remains far below the estimated $175 billion annually required to protect oceans, the High Seas Treaty is accelerating private-sector participation through instruments like blue bonds. For example, private-sector blue bonds have already mobilized $9 billion, with impact funds increasingly targeting SDG 14 (Life Below Water) What the blue economy means to the investment industry^[9].

Venture capital is also shifting focus to the blue economy, albeit modestly. Less than 1% of total sector investments currently flow into ocean technologies, but this is changing as regulatory clarity improves. Startups supported by accelerators like the Blue Action Accelerator are developing solutions to reduce emissions, enhance biodiversity, and optimize aquaculture—sectors poised for growth as MPAs expand under the treaty Why 2025 can be a breakthrough year for the blue economy^[10].

Challenges and the Path Forward

Despite progress, challenges persist. As of mid-2025, only 50 of 136 countries have ratified the treaty, with major maritime powers like the U.S., China, and Russia delaying participation Historic UN High Seas Treaty is a turning point for ocean protection and restoration^[11]. This raises concerns about enforcement, as the treaty lacks a punitive body and relies on national compliance. Investors must also navigate geopolitical tensions in disputed waters, such as the South China Sea, where overlapping territorial claims complicate MPA implementation Nations ratify world’s first treaty to protect marine biodiversity in international waters^[12].

However, the treaty's first Conference of the Parties in 2026 will establish governance frameworks, potentially unlocking further investment. For now, early adopters—such as Norway, the UK, and Singapore—are leading in blue economy innovation, leveraging their regulatory leadership to attract capital Ocean Trends 2025: Conservation Breakthroughs & Blue Economy^[13].

Conclusion

The High Seas Treaty is reshaping the blue economy by creating a transparent, equitable, and ecologically responsible framework for ocean-based industries. While challenges remain, the treaty's emphasis on technology transfer, MPAs, and sustainable finance is driving a wave of innovation and investment. For capital allocators, the message is clear: the blue economy is no longer a niche market but a critical frontier for aligning profit with planetary health.
