“It’s higher down the place it’s wetter,” crooned Sebastian, the Disney crab, to the Little Mermaid. The sentiment is enthusiastically shared by a gaggle of traders who’ve guess hundreds of thousands on extracting helpful metals from the seabed. A political push for US self-reliance in strategic commodities might be music to their long-suffering ears.
President Donald Trump is anticipated to concern an govt order that will step up plans to reap polymetallic nodules that kind beneath the Pacific. These black lumps are wealthy in nickel, cobalt and manganese — commodities closely used within the making of batteries for cell gadgets and electrical automobiles. Nickel additionally elements within the manufacturing of stainless-steel, enhancing its industrial significance.
Deep-sea nodule harvesting is controversial as a result of the seabed, and the results of scraping it, stay considerably mysterious. Few mining trials have been undertaken. Sessile megafauna — massive organisms connected the ocean flooring — are presumably not followers. Non-government organisations, and plenty of nations together with the UK, desire a moratorium. For Trump to concern permits with out the oversight of the Worldwide Seabed Authority (ISA) would straight problem the worldwide consensus.
However within the eyes of a president who sees commerce ties with financial rivals as vulnerabilities, there’s a geopolitical crucial at stake. China dominates manufacturing of strategic metals, and has restricted exports of some in response to US tariffs. Tapping provide nearer to house is on the very least a negotiating chip the White Home can use for protecting international provide strains open, and an insurance coverage coverage in case they’re closed.
Whether or not this can remodel US geopolitical fortunes is unclear — although it might actually be a sea change for The Metals Firm, a listed prospector that has been lobbying onerous for permission to start out trawling. TMC went public in 2021 by merging with a particular goal acquisition firm. The deal, dealt with by Citigroup and Nomura, was a flop. The shares, regardless of doubling this yr, are 80 per cent beneath their early peak.

A Trump go-ahead would likely carry a well timed infusion of money into the sector from exterior traders. TMC had $3.5mn on its steadiness sheet on the finish of 2024, and a mortgage facility part-funded by chief govt Gerard Barron. The corporate estimated in 2021 that it might want $7bn to get to full manufacturing, although the addition of accomplice firms could have introduced that down since. A rival deep-sea hopeful, Loke Marine Minerals, lately filed for chapter.
Granted, even with funding and White Home approval, marine-mineral supremacy is a distant prospect. The ISA, a UN offshoot that claims jurisdiction over the excessive seas, could cry foul. Nonetheless, Trump has proven a knack for creating dramatic — if momentary — funding booms. With tariffs freezing commerce alternatives on land, maybe Sebastian was proper: it’s hotter underneath the water.
