Deep-Sea Minerals: Geopolitical Race for Critical Resources

The vast, unexplored depths of the ocean floor hold immense reserves of critical minerals vital for the global energy transition and advanced technologies. As terrestrial reserves dwindle and geopolitical supply chains become increasingly volatile, deep-sea mining (DSM) has rapidly ascended the international foreign policy agenda. This nascent industry promises to unlock polymetallic nodules, cobalt-rich crusts, and seafloor massive sulfides, rich in nickel, cobalt, copper, manganese, and rare earth elements crucial for electric vehicles, renewable energy infrastructure, and defense applications. However, the pursuit of these riches occurs largely in the Area – the seabed and ocean floor beyond national jurisdiction – governed by the principle of the Common Heritage of Mankind. This principle, enshrined in the United Nations Convention on the Law of the Sea (UNCLOS), mandates that these resources be managed for the benefit of all humanity, with particular consideration for developing states.

The delicate balance between resource imperative and environmental stewardship defines the current geopolitical discourse on deep-sea mining.

The primary structural driver for the deep-sea mining push is the surging global demand for critical minerals. The transition to a green economy, with its reliance on electric vehicles and renewable energy technologies, has created an insatiable appetite for metals like cobalt and nickel. Terrestrial mining often faces environmental, social, and governance (ESG) challenges, alongside geopolitical risks concentrated in a few supplier nations. This has pushed nations and corporations to look seaward. However, the regulatory framework governing the Area is still incomplete. The International Seabed Authority (ISA), established under UNCLOS, is mandated to regulate activities in the Area, but it has yet to adopt a comprehensive mining code. The activation of the “two-year rule” by Nauru in 2021 has accelerated the process, potentially allowing commercial mining to commence without fully developed regulations, sparking widespread concern. Key root causes include a lack of scientific understanding of deep-sea ecosystems, which are often unique and fragile, making environmental impact assessments complex and contentious. Furthermore, the technological capabilities for deep-sea extraction are rapidly advancing, outpacing regulatory development and creating a governance vacuum.

The implications of unregulated or poorly regulated deep-sea mining are profound for both India and the global order. For India, a major developing economy with ambitious net-zero targets and a rapidly expanding manufacturing sector, securing a stable supply of critical minerals is paramount. Dependence on a few countries for these resources poses a significant strategic vulnerability. Unregulated mining could lead to environmental degradation of the global commons, impacting marine biodiversity, ocean currents, and potentially exacerbating climate change effects, which disproportionately affect coastal nations like India. Geopolitically, the race for deep-sea minerals could intensify rivalries, particularly between major powers like the US and China, who are both keen to secure future supply chains. It risks weaponizing resource access and undermining the spirit of multilateral cooperation inherent in UNCLOS. The principle of the Common Heritage of Mankind could be eroded, leading to a ‘tragedy of the commons’ scenario where short-term gains outweigh long-term global well-being. This could also deepen the North-South divide, as developing nations, often lacking the technology and capital for DSM, might feel excluded from the benefits.

India has proactively engaged with the deep-sea mining discourse, recognizing its strategic importance. A key initiative is the Deep Ocean Mission (DOM), launched in 2021, which aims to develop technologies for deep-sea exploration and sustainable utilization of ocean resources. Under DOM, India has been allotted a site of 75,000 sq. km in the Central Indian Ocean Basin (CIOB) by the ISA for exploration of polymetallic nodules. India is an active member of the ISA and has consistently advocated for a balanced approach that prioritizes environmental protection while ensuring equitable access to resources. India’s stance aligns with the broader developing world’s call for technology transfer and capacity building to ensure that the benefits of deep-sea mining are shared equitably. Furthermore, India is a signatory to UNCLOS and is closely monitoring the ongoing negotiations at the ISA regarding the finalization of the mining code, ensuring its strategic interests are represented. India also participates in discussions around the BBNJ Agreement, which aims to protect biodiversity in areas beyond national jurisdiction, recognizing the interconnectedness of ocean health and resource extraction.

A strategic way forward demands innovative approaches to governance and technology. Firstly, the ISA must prioritize the finalization of a robust, science-based mining code that incorporates the precautionary principle and strong environmental safeguards, including effective monitoring and enforcement mechanisms. This requires an adaptive governance framework that can evolve as scientific understanding of deep-sea ecosystems improves. Secondly, there is a need for significant investment in independent scientific research to fill critical knowledge gaps about deep-sea biodiversity and the potential impacts of mining. This could be facilitated by an international scientific panel. Thirdly, innovative financing mechanisms could be explored to support capacity building and technology transfer to developing nations, ensuring equitable participation and benefit sharing. Fourthly, exploring alternative sources of critical minerals, such as urban mining and advanced recycling technologies, could reduce the pressure on deep-sea resources. Finally, fostering public-private partnerships focused on sustainable extraction methods and impact mitigation technologies, alongside transparent reporting, is crucial. This integrated approach can help navigate the complex future of ocean mining.

India’s strategic interests in deep-sea mining are multifaceted. Economically, securing a reliable and diversified supply of critical minerals is essential for its industrial growth, particularly in sectors like electronics, defense, and renewable energy. This reduces reliance on geopolitically sensitive supply chains and strengthens India’s economic autonomy. Technologically, the Deep Ocean Mission aims to indigenize deep-sea exploration and mining technologies, positioning India as a leader in this frontier area. Environmentally, India’s commitment to sustainable development necessitates ensuring that any deep-sea mining activities are conducted with minimal ecological impact, aligning with its broader climate action goals. Geopolitically, active participation and leadership in the ISA and other multilateral forums allow India to shape global norms and regulations, ensuring that the principle of the Common Heritage of Mankind is upheld and that benefits are shared equitably. This enhances India’s influence as a responsible stakeholder in global ocean governance and reinforces its strategic autonomy by diversifying resource access.

The regional and global dimensions of deep-sea mining are marked by significant geopolitical competition and environmental concerns. Globally, the US and China are key players, with China having numerous exploration contracts and the US, despite not ratifying UNCLOS, expressing strategic interest. Pacific Island nations, highly vulnerable to marine ecosystem degradation, have emerged as strong advocates for a moratorium or precautionary pause on deep-sea mining. Norway’s recent decision to open its continental shelf to deep-sea mining has further complicated the global regulatory landscape, setting a potential precedent for national jurisdiction over deep-sea resources. This highlights the tension between national economic interests and the protection of the global commons. The BBNJ Agreement, once ratified and implemented, could provide a crucial framework for environmental impact assessments and marine protected areas in the Area, offering a pathway for coordinated regional and global action to protect marine biodiversity, as highlighted in discussions around implementing the BBNJ Treaty for Global Commons.

As of April 2026, the International Seabed Authority (ISA) continues to grapple with the finalization of the deep-sea mining code, following the expiration of the “two-year rule” triggered by Nauru. This has created a precarious situation where commercial exploitation could technically proceed without comprehensive regulations, leading to calls from environmental groups, scientists, and several nations for a moratorium or a precautionary pause. Major developments include ongoing negotiations at ISA Council meetings, where member states are debating critical aspects like environmental impact assessment standards, financial terms, and compliance mechanisms. The scientific community has published numerous studies highlighting the potential irreversible damage to unique deep-sea ecosystems. Several countries, including France, Germany, and a growing number of Pacific Island states, have publicly supported a moratorium, while others, like Norway and various developing nations, emphasize the need for resource security and equitable benefit sharing.
