Argentina’s critical-minerals boom comes with a choice

Argentina has attracted the critical-minerals investment it was seeking. The harder question is what it does with it.

On July 31, 2026, Argentina announced a critical-minerals partnership with South Korea covering “the entire lithium value chain.” The same day, it cleared Posco to expand lithium-carbonate output at the Salar del Hombre Muerto for export. Against a backdrop of shifting global supply chains and intensifying great-power competition, and with the Régimen de Incentivo para Grandes Inversiones (RIGI) investment scheme drawing in capital, Argentina sits at an inflection point that could reshape both its economy and its place in critical-minerals geopolitics.

President Javier Milei and his government has read this moment well. Capital is flowing, suitors are lining up, and the deals are getting signed. RIGI did what it was designed to do, and it did it fast, exactly when the United States and its partners are scrambling to build critical-mineral supply chains that do not run through China.

The harder question is the one that comes after the money lands: what does Argentina want to be in this supply chain?

For now, the biggest deals remain concentrated in extraction. Argentina can keep selling ore, which is familiar and already earning, or treat this boom as a chance to build something more robust. Building domestic processing capacity does not require slowing extraction down. But Argentina’s choice to handle this investment rush differently has to be made deliberately, because drifting into a raw-export economy by default means inheriting every risk that comes with it.

At the bottom of the chain

Argentina has the lithium and copper global markets are seeking. But it does not have much of the refining capacity that turns that raw material into usable product. China controls well over half of global lithium refining, so even as Argentine output climbs, the country remains exposed to price-setting dynamics beyond its control. If Argentina decides to remain primarily an exporter of raw materials, it will remain vulnerable to the swings of global commodity markets, as the case with agricultural prices.

The ambition to move up exists, but it is thin. YPF’s technology arm built the country’s first lithium-cell plant, a genuine milestone, though at pilot scale, on the order of a thousand stationary batteries a year. That’s closer to a demonstration than an industry. Under Milei the government has steered YPF back towards oil and gas and the battery effort has stalled. The rhetoric reaches for the whole value chain while the contracts keep stopping  short of wider industrial development. Posco’s Argentine carbonate, tellingly, is shipped out to be turned into higher-value hydroxide in Korea.

Argentina has been here before, with beef and soy. The latter offers a useful precedent, though not a perfect one. Rather than ship the raw bean, the country built domestic crushing capacity and became one of the world’s leading exporters of soymeal and soybean oil. Not that every commodity follows the same path, but domestic capacity can allow a resource-rich country to capture more value. Lithium and copper are the next tests.

None of this is easy, and pretending otherwise would be a mistake. Lithium chemistry is not soybean crushing, the capital requirements are larger and the technical bar higher. Other resource rich countries have faced similar situations. Indonesia is a cautionary tale: it banned raw nickel exports in 2020 to force domestic processing, grew its nickel industries roughly fivefold and now dominates global supply. In practice, the policy led to an industry largely dependent on Chinese capital. Chinese firms now control around three-quarters of domestic refining. Should Argentina seek to increase its role in the wider supply chain, it will surely require foreign capital. But by setting the terms going in, Argentina may be able to capture more value.

If done correctly, building processing and manufacturing at home could also offer a direct pathway to creating new formal-sector jobs and increasing domestic know-how. Argentina’s economy has shed more than 270,000 private-sector registered salaried jobs since December 2023, the start of Milei's administration, according to official employment data. Manufacturing has been among the sectors hit the hardest.

The current RIGI application window runs until July 2027, while the final structure of the proposed ‘Super RIGI’ scheme – which targets even multi-billion-dollar investment – is still being haggled over in the Senate. A long-term strategy to capture a wider slice of the critical-minerals supply chain could help reverse the trend, no matter who wins in 2027.

Provincial risk

A large share of the political risk in Argentine mining lies where the projects are ultimately executed. Lithium development is concentrated in Jujuy, Salta and Catamarca, while major copper projects are spread across the Andean provinces.

Growth in the sector will partly depend on whether the communities that host these projects are willing to live with them. Provinces must build sophisticated coordination structures that spread beyond individual projects, working across jurisdictions and beyond their basic administrative duties.

Benjamin Gedan, Senior Fellow and Director of the Latin America Program at the Stimson Center, told the Times that a social licence will be decisive. Measured against Peru and Bolivia, he said, “it will be important for Argentina to build a better model,” adding that “because the provincial governments play such a big role in mining in Argentina, policy should theoretically better reflect local realities.”

Water is where that acceptance is generally won or lost. Argentine lithium comes from brine under some of the driest parts of the country and copper projects need large, long-term water supplies. The question communities weigh is whether the benefits stay long enough to matter locally. Whether local communities enjoy job growth without having to accept harsh trade-offs in the form of environmental degradation will be key to long-term project viability.

This is also where domestic processing could help politically. A province that sees plants, payrolls and a tax base has more reason to grant and keep consent than one that only watches raw carbonate roll out. Here, provincial power cuts both ways. It forces local buy-in, but a tangled regulatory map and thin administrative capacity can also slow the very projects RIGI was built to speed up.

Once again, the Indonesia case is helpful. Jonas Nahm, Andrew W. Mellon Associate Professor at Johns Hopkins SAIS and a former White House industrial strategy economist, said in conversation with the Times that when Indonesia sought external partners to build its processing capacity “there were very few western firms that came, primarily on environmental and governance grounds.”

In the Pink House

Currency risk used to be the first thing investors raised about Argentina, since capital could get trapped and profits were hard to move home. Milei’s RIGI scheme was built to neutralise exactly that: registered projects get guaranteed access to foreign currency and free repatriation, locked in for thirty years, so for the megaprojects driving this boom the classic trap is largely handled.

The open question is whether the guarantees last.

Nothing legally bars Argentina from a cathode or cell industry later. The problem is timing. The framework that would make such an industry bankable is the part with an expiration date.

The proposed Super RIGI package offers a five-year application window for projects above US$1 billion per stage, but cathode, cell production and battery assembly need a long development runway. This is also true of scaling copper production. If Milei fails to pass follow-up legislation, or a Peronist victory in 2027 pivots the country back towards more inward-looking development, the capital those projects require could dry up before they are built.

Extraction is protected for thirty years. However, everything above it rests on a shorter and far more fragile political runway, and that gap is the reason the decision cannot be left to drift.

Not alone on the flats

Chile faces the same salt flats and many of the same buyers, and has spent the past year setting the terms of its lithium future, building state leverage and pushing refining and cathode work onshore. That approach also has costs. Writing the rules first means moving slower and reasonable people, Milei included, might call it surrendering an edge. 

Argentina does not need to copy its neighbour, but prioritising extraction speed is not enough for a long-term sector strategy.

Argentina’s leverage is real, though it should not be oversold. Nahm put the pattern plainly: resource-rich countries “hold the chokepoints for a lot of these new industries,” yet “historically they’ve not really captured anything but royalties and some raw exports, the classic resource-curse pattern.”

What is different now is timing. Asked how a country breaks that pattern, Nahm was candid about the lack of a playbook: “I don’t think there’s a good template that I can think of, but I think there’s an opening right now.”

The same forces drawing capital into Argentine extraction – a global push to diversify away from a chain China dominates – could draw partners into processing too, if Argentina decides to compete for it.

Milei has gotten Argentina into the room. Whether it turns a genuine opening into something more substantial – a seat at the table in an increasingly competitive global industry – or settles for being another raw-materials exporter is the decision that will determine what this moment was worth.
