Update (0710ET):
Earlier this month, US Treasury Secretary Scott Bessent arranged a $20 billion currency swap with Argentina’s central bank to stabilize the country’s bond market ahead of Sunday’s elections. The midterm results were surprising, as President Javier Milei’s party scored a major comeback, and the move may now pay dividends for the US.
Goldman analyst Clara Mourey provided clients with midterm election results:
With 94% of ballots counted, President Milei’s party, La Libertad Avanza, received 40.8% of the votes, above expectations, and will increase its representation in Congress starting December 10, up from the current 10% in the Senate and 15% in the Lower House. Importantly, the government’s representation would exceed the one-third threshold in the lower house, and together with allies also in the Senate. This outcome would enhance the President’s veto authority and bolster governability.
The left-wing coalition Fuerza Patria received 24.4% of the votes, and together with other Peronist groups reached 31.6% of the votes. Finally, the group of governors united under the Provincias Unidas coalition received 7.0% of the vote.
Aboard Air Force One earlier while on his Asia tour, Trump told reporters that Sunday’s midterm election results were a “big win” for Milei’s party. “Not only did he win, he won by a lot.”
Trump’s backing of Milei is part of a strategic political shift across Latin America, following decades in which failed socialist leaders sent the country’s economy into the dumps.

One of Bessent’s bets included over $1 billion in peso purchases, according to Bloomberg estimates, which appears to have paid off.
The nation’s debt jumped across the curve in early trading, with dollar notes due in 2035 up more than 13 cents to trade at a record 70.34 cents on the dollar.

A stronger Argentine currency in Monday’s trading session will mean the US could net hundreds of millions of dollars in gains.

In the US, Global X MSCI Argentina ETF (ARGT) jumped 17%.

“That election made a lot of money for the United States,” Trump said Monday. “The bonds have gone up,” he said. “The whole debt rating has gone up.“
Goldman’s Mourey continued, “The election results improve the outlook for structural reforms in the second half of the Administration. Following the election, investors will monitor any shifts to the government’s economic policy mix, especially those related to the exchange rate and monetary regime. In the months leading up to the elections, Argentine assets were affected by heightened political and policy uncertainty.”

In a separate note earlier, UBS analyst Matthew Cowley told clients, “The peso is expected to appreciate post-election, alleviating currency pressure, though Argentina’s $48 bn debt payments by 2027 remain a concern. A reinforced political mandate and potential foreign investment flows could stabilize reserves and support international debt market re-entry. Milei’s victory signals optimism for Argentina’s economic trajectory, with key reforms now more likely to advance.”
Bessent told reporters earlier, “Now I think the market is going to take care of itself and it’s going to have a lot of confidence in his policies,” referring to Milei, adding, “They have some big refinancings next year, but the Argentinian people have spoken.”
Bessent also congratulated Milei on X:
Congratulations to President @JMilei on La Libertad Avanza’s very successful midterm election. President Milei has a renewed mandate for change.

According to the English-langauge Buenos Aires Times at 9:30pm local time, “Official results point to a decisive win for President Javier Milei and La Libertad Avanza. The only force to be running in every province, the ruling party’s alliance with ex-president Mauricio Macri’s PRO party has won it more than 40 percent of the national vote for lower house deputies.”
Official results now in from Argentina…

The Wall Street Journal reviews of the significance:
That means it should secure at least one-third of the seats in both chambers—the critical threshold that allows Milei to preserve his veto power and defend his sweeping decrees. The result, stronger than most polls had predicted, gives Milei fresh political momentum after months of unrest over deep spending cuts and a grinding recession last year.
It also shores up his standing with Washington and the International Monetary Fund, which have tied future financial support to the survival of his austerity experiment. Market analysts expect Argentine bonds and the peso to rally when trading opens Monday, reflecting relief that Milei still has political traction. The U.S. announced a $20 billion currency swap this month to prop up Argentina’s currency and promised to raise another $20 billion from private banks and sovereign-wealth funds.
My friend President Javier Milei’s party has swept Argentina’s national legislative elections, winning 40.84% of the vote compared to 24.50% for the Kirchnerist bloc, with 91% of ballots counted.
President Trump and I simply say, “VIVA LA LIBERTAD, CARAJO!”

Recall the crucial words of Trump from earlier this month, “If he wins, we’re staying with him. And if he doesn’t win, we’re gone.” He just survived and thrived in this major test of his austerity agenda, despite a public turnout which was a low in decades.

Some 36 million eligible Argentines are headed to the polls Sunday for legislative elections which are key to determining the fate of President Javier Milei’s sweeping reform agenda, and could unsettle financial markets if his support collapses, despite record US assistance in the form of the ultra-controversial big beautiful bailout from the Trump administration, which could also hang in the balance.
The midterm vote is being closely watched internationally, as it marks the first nationwide referendum on the self-styled anarcho-capitalist’s austerity measures and economic deregulation efforts since he assumed office two years ago. At the start of this past week, Argentina assets soared on the heels of US Treasury Secretary Scott Bessent calling the South American country “a systemically important US ally in Latin America,” adding that the US Treasury “stands ready to do what is needed within its mandate to support Argentina. All options for stabilization are on the table.”

But the potential $40 billion bailout package for Argentina is also on the line (Bessent indicated the extra $20 billion on top of the initial $20bn would come from “the private sector” – which seems somewhat wishful given the scenario of private investors wanting to risk such sums in volatile Argentina). The aid could be withdrawn by Trump if his populist ally Milei tanks. President Trump even spelled out, “If he doesn’t win, we’re not going to waste our time, because his opponents’ philosophy has no chance of making Argentina great again.”
On Sunday, voters are choosing half of the seats in the Chamber of Deputies and one-third of the Senate. It was the campaign period leading up to the vote which saw a sharp decline in the peso, prompting Milei to the request emergency financial support from Washington. Should the Sunday vote go against Milei – and there are a number of signs suggesting this will be the case – then Trump “will not be generous” – as he’s forewarned in prior comments.
President Milei’s La Libertad Avanza party, which remains a newcomer in Argentine politics, currently holds just 37 seats in the Chamber of Deputies and six in the Senate, giving it less than 15% of the total seats in Congress. The party desperately needs to expand its representation to at least one-third of Congress, a goal that would strengthen its ability to block opposition efforts to derail Milei’s ambitious agenda.
If Milei’s party performs weak, this could serve to quickly resolve domestic controversy for Trump at home:
On October 19, a reporter asked Trump why he decided to aid Argentina despite concerns among US soya producers. “Argentina is fighting for its life,” Trump answered. “Young lady, you don’t know anything about it. … They have no money. They have no anything.”
US aid to Argentina didn’t directly harm US soya producers – they have been hurt by a separate Trump policy, his trade war with China. But the timing of the aid and the soya bean export troubles pose a problem of optics for the White House.
But as for “optics” – a loss in these midterms will mark a defeat of US credibility in the region, given the aforementioned multibillion-dollar lifeline from the White House.
With a few hours until polls close, reports of low voter turnout, a bad sign for the Argentine Trump ally…
🇦🇷Low voter turnout in the midterms in Argentina. This isn’t a good sign for Milei’s party as Peronists have a better ‘get out the vote’ apparatus. The midterm election in the province of Buenos Aires where Milei’s party underperformed compared to the polls also saw low turnout. https://t.co/1jt0cZlllk

Milei himself faces reelection in 2027, and the national direction after Sunday will signal whether Milei’s “chainsaw” austerity program will have any staying power. Politico notes, “LLA is expected to gain seats — though not enough to secure a majority against the left-wing Peronist coalition — but if the president’s coalition underperforms, it could lead to a broad selloff of Argentinian assets.”
The vote is happening between 8 a.m. and 6 p.m. (1100–2100 GMT), and some preliminary results are expected to emerge roughly three hours after polls close.
