Trump Tariff Shock Rattles Argentina’s Milei-Caputo Trade
Argentina · Economy
Key Facts
—Tariff shock. Trump imposed 25% tariffs on steel and aluminium imports without exceptions, directly hitting Argentina as the seventh-largest aluminium supplier to the US
—Reciprocal risk. A parallel order to prepare country-by-country reciprocal tariffs places Argentina’s roughly US$30 billion annual trade with the United States in the line of fire.
—Lifeline intact. The US$20 billion US Treasury swap line and the February 2026 ARTI trade agreement remain in place, with no verified cancellation or suspension.
—Macro progress. Argentina’s annual inflation fell from 211% in 2023 to roughly 33% in early 2026, with GDP growth of 4.4% in 2025 and a primary fiscal surplus of 1.4% of GDP.
—Market repricing. Argentine dollar bonds had rallied roughly 10% and Buenos Aires stocks 15% on the swap-line announcement; the new tariff uncertainty forces investors to discount future export earnings and re-price political risk.
The Milei-Caputo trade faces its stiffest external test yet as Donald Trump’s sweeping new metals tariffs and reciprocal-duty directive darken the outlook for Argentina’s US-anchored reform story, even though the core lifeline and trade pact remain legally intact.
What the Trump move actually entails
The White House announced a 25 per cent tariff on all foreign steel and aluminium imports, explicitly applied “without exceptions or exemptions.” For Argentina, this is not a theoretical concern: US Census Bureau data shows the country was the seventh-largest supplier of aluminium to the United States in the previous year.
Simultaneously, Trump ordered his administration to prepare “reciprocal” tariffs that would match foreign duties country by country. That directive puts Argentina’s roughly US$30 billion annual bilateral trade with the US squarely in the crosshairs, even though no Argentina-specific punitive measure has yet been enacted.
The architecture of the Milei-Caputo trade
Markets have been riding a powerful narrative built around President Javier Milei and Economy Minister Luis Caputo. The core bet is that aggressive austerity, deregulation, and a crawling-peg exchange rate can stabilise an economy that was running annual inflation above 200 per cent when they took office.
Caputo delivered a 50 per cent peso devaluation early on, moving the official rate from 400 to 800 pesos per US dollar. That shock, combined with deep subsidy cuts, helped produce a primary fiscal surplus of about 2.1 per cent of GDP in the first eleven months of 2024 and an overall budget surplus of 0.3 per cent for the full year.
The external anchor of the trade is equally important. In October 2025, US Treasury Secretary Scott Bessent announced a US$20 billion swap line for Argentina, plus direct US purchases of pesos—the first large-scale Treasury rescue of a foreign economy since the US$20 billion Mexico package in 1995.
The trade deal that was supposed to shield Argentina
On 5 February 2026, the two countries signed the comprehensive United States–Argentina Agreement on Reciprocal Trade and Investment, known as ARTI. Argentina agreed to eliminate tariffs on more than 200 categories of US goods, including machinery, chemicals, pharmaceuticals, and vehicles, while the US abolished duties on over 1,600 Argentine products.
A headline concession for Buenos Aires was a fivefold increase in the duty-reduced beef quota, from roughly 20,000 tons to 100,000 tons per year. The deal also conferred “Major Non-NATO Ally” status on Argentina, which was sold domestically as protection against Section 232 national-security tariffs on metals.
It is precisely that protection which now looks uncertain. Trump’s insistence on applying metals tariffs “without exceptions” directly tests the practical value of Argentina’s newly granted ally status, even though the ARTI text itself has not been revoked or suspended.
Why the Milei-Caputo trade is suddenly under pressure
The market reaction to Bessent’s swap-line announcement in October 2025 was euphoric: Argentina’s dollar-denominated bonds jumped roughly 10 per cent and Buenos Aires stocks surged 15 per cent. Those gains were built on the assumption of a one-way liberalisation path and an increasingly open, protected channel to the US market.
Trump’s metals tariffs and reciprocal-duty directive reintroduce exactly the kind of uncertainty that the Milei-Caputo trade had been designed to eliminate. Investors must now discount future export earnings from key sectors and re-price the political risk embedded in a relationship that had seemed reliably supportive.
Trump also publicly accused Argentina of exporting steel in “unsustainable quantities” and questioned the reliability of Argentine trade statistics. That rhetoric, even without formal action, raises the perceived risk that further friction could erode the benefits of the trade deal.
What remains intact—and what is unconfirmed
It is important to separate verified facts from market chatter. No source confirms that the US$20 billion swap line has been cancelled, reduced, or subjected to new penalty clauses tied to Argentine politics.
Similarly, the ARTI agreement signed in February 2026 remains in force, with no evidence of formal suspension or revocation. The metals tariffs are a general measure, not an Argentina-specific penalty, and the reciprocal-tariff process is still at the preparatory stage.
What markets are reacting to is a regime-change risk in the narrative, not a documented termination of the US–Argentina support architecture. That distinction matters for investors trying to separate signal from noise.
The macro backdrop: real progress, real fragility
The Milei-Caputo trade is not built on wishful thinking alone. Annual inflation has collapsed from 211 per cent in 2023 to roughly 33 per cent in early 2026, and monthly inflation fell from 25.5 per cent in December 2023 to 2.4 per cent by November 2024.
GDP contracted by about 3 per cent in 2024 but rebounded to 4.4 per cent growth in 2025, with forecasts of 3 to 4 per cent for 2026. Poverty fell to 28.2 per cent, its lowest level since 2018, and the primary fiscal surplus reached 1.4 per cent of GDP.
Yet unemployment rose to 7.5 per cent in late 2025, up roughly one percentage point year on year, and job quality has deteriorated. The reform programme still depends on Milei’s political capacity to sustain austerity amid social pressure, a calculation that becomes harder if external anchors weaken.
What the Milei-Caputo trade means for investors and expats now
For international investors, the tariff shock is a reminder that emerging-market trades built on geopolitical alignment carry two-way risk. The Argentine story remains compelling on domestic fundamentals, but the external pillar now requires a sharper discount for US policy volatility.
For expats and frontier-living professionals, the macro stabilisation is tangible: inflation is no longer a daily crisis, and the fiscal accounts are in surplus. The risk is that a prolonged trade dispute could slow growth and weaken the peso, eroding the purchasing power that makes Argentina an attractive base.
The key variable to watch is whether the reciprocal-tariff process produces measures that specifically target Argentine agricultural or manufactured exports. If it does, the carefully negotiated gains of ARTI could be partially offset, changing the calculus for anyone with long-term exposure to the country.

Frequently Asked Questions
Has Trump cancelled the US$20 billion swap line with Argentina?
No. All available reporting confirms the swap line announced by Treasury Secretary Scott Bessent in October 2025 remains in place. Trump has warned that continued US backing depends on Milei’s reform progress and electoral fortunes, but no formal cancellation or reduction has been documented.
Does the new tariff announcement revoke the US–Argentina trade deal signed in February 2026?
It does not. The ARTI agreement remains legally in force, and the 25 per cent metals tariffs are a general measure applied to all foreign suppliers, not an Argentina-specific penalty.
However, the tariffs test the practical value of Argentina’s Major Non-NATO Ally status, which was meant to shield it from Section 232 measures.
What should investors watch next in the Milei-Caputo trade?
The critical signal is whether the reciprocal-tariff process produces measures that specifically target Argentine goods beyond steel and aluminium. Investors should also monitor any change in the swap-line facility, Milei’s domestic political standing ahead of key electoral tests, and monthly inflation prints for signs that the disinflation trend is holding.
