Latin America Argentina

Buenos Aires Stocks Jump Almost 22% as Milei Gains Seats and Leverage

By · October 27, 2025 · 2 min read

Argentina woke up to a different political map and a roaring market. President Javier Milei’s La Libertad Avanza (LLA) outperformed expectations in Sunday’s midterms, edging Peronists in the pivotal Buenos Aires province and expanding its footprint in Congress.

It still lacks an outright majority, but it now holds a far stronger bargaining position as new lawmakers take office on December 10.

Markets reacted instantly. The S&P Merval jumped roughly 20 percent, sovereign bonds rose about 10–15 cents, and the peso strengthened by around 10 percent in early trading.

Investors read the vote as a mandate to keep pushing Milei’s core agenda: fewer currency controls, simpler taxes, and labor changes aimed at reviving formal hiring and attracting capital.

The story behind the story is how politics, money, and geopolitics converged. This midterm decided half the lower house (127 seats) and a third of the Senate (24 seats)—the difference between narrow gridlock and workable coalitions.

Buenos Aires Stocks Jump Almost 22% as Milei Gains Seats and Leverage.

Argentina’s Market Rally Tests Milei’s Reform Credibility

LLA’s advance, especially in Buenos Aires province, breaks a symbol of long-standing Peronist dominance and gives Milei leverage to negotiate reforms with moderates.

It also arrived alongside explicit U.S. support: a $20 billion currency swap already signed to stabilize the peso and a proposed additional $20 billion in financing under discussion, signaling Washington’s strategic bet on Argentina’s turnaround.

For readers outside Argentina, here’s why it matters. Markets are forward-looking scoreboards. Monday’s rally says investors believe political risk just fell and the odds of reform rose.

If the government turns this window into durable policy—curbing money printing, rebuilding reserves, and easing the way for private investment—borrowing costs can fall, the currency can stabilize, and growth can reappear.

If coalition talks stall or reforms are diluted, today’s relief could fade as quickly as it came. Argentina now enters its hardest phase: converting electoral momentum into concrete laws and execution.

The promise is real—a cleaner rulebook and a reopened economy. So are the risks—no majority, fragile confidence, and little room for mistakes.
