Today’s Focus
Argentine stocks and bonds rallied on Monday, pulled by Brazil. The S&P Merval, the main index of the Buenos Aires exchange, gained 3.7% to 2,869,488 points. Argentina’s country risk fell to 599 basis points.
Country risk is the extra yield investors demand to hold Argentine dollar bonds instead of US Treasuries. A fall means cheaper borrowing for the state and for companies.
What matters today. For US investors, Argentine ADRs and bonds jumped together, which shows how closely Buenos Aires follows the regional mood.
01 The session in one read
The Merval closed at 2,869,488 points, up 3.7% in pesos. It had lost 4.4% the week before and fell 7.1% in September (El Cronista).
Argentine shares listed abroad rose up to about 10%. Dollar bonds, the Bonares and Globales, gained 2.1% on average. Country risk fell 49 points, or 7.6%, to 599 (Infobae).
The official wholesale dollar ended near 1,520 pesos, roughly unchanged from Friday.
The driver was Brazil. Flávio Bolsonaro’s first-round lead surprised the polls, and Brazil’s Ibovespa gained 7.70%.
Assessment — A regional rebound after a weak month MEDIUM
The rally follows a hard September, so part of it is a bounce. The shared cause is Brazil, not a change in Argentine data.
A calm peso market made it easier for bonds and stocks to rise together.
02 The day’s numbers
| S&P Merval | 2,869,488 | +3.7% | Rebound after a 7.1% fall in September |
| Country risk (JP Morgan) | 599 bps | −7.6% | Down 49 points |
| Dollar bonds (Bonares, Globales) | — | +2.1% | Average gain |
| USD/ARS wholesale | about 1,520 | — | Roughly unchanged |
| ARGT (US-listed Argentina ETF) | US$89.53 | +5.93% | Dollar-based investors |
A basis point is one hundredth of a percentage point, so 599 basis points means an extra yield of 5.99 points over US Treasuries.
The RT feed shows the wholesale peso at 1,520 against 1,524.88 a session earlier. Infobae reports no change on the day. The two sources agree within rounding.

The session read
The S&P MERVAL rose 3.68%, with breadth negative — 4 of 14 names higher. Utilities led, while Consumer Disc. lagged.
03 Why it moved — Brazil’s vote and cheaper credit
Brazil’s election was the trigger. Flávio Bolsonaro won 47.03% of the first-round vote, ahead of the polls, and Brazilian stocks jumped (Infobae). Funds that own both markets added Argentine assets in the same session.
The drop in country risk below 600 matters on its own. It lowers the cost of financing for Argentine companies that borrow in dollars.
Wall Street was firm as well, with US indexes up between 0.2% and 1.1% (Infobae).
04 The day’s movers
| Mercado Libre (MELI, New York) | +9.6% | — | Largest ADR gain in Infobae’s list |
| Banco Francés (ADR) | +7.7% | — | Lender |
| Grupo Financiero Galicia (GGAL, New York) | +6.58% | — | Lender, RT close |
| Banco Macro (BMA, New York) | +6.55% | — | Lender, RT close |
| YPF (YPF, New York) | +3.16% | — | Oil producer, RT close |
Banks and the e-commerce group led the US-listed gains. Local closes in pesos were also higher: Galicia and Banco Macro gained about 5% in Buenos Aires (RT), and YPF gained 2.17%.
05 The regional scoreboard
| Ibovespa | Brazil | +7.70% |
| S&P Merval | Argentina | +3.68% |
| COLCAP | Colombia | +2.69% |
| S&P IPSA | Chile | +1.91% |
| S&P/BMV IPC | Mexico | +0.69% |
Argentina was the region’s second-strongest market after Brazil. Colombia and Chile followed, and Mexico trailed.
06 The technical picture
The Merval’s gain only retraces part of the recent losses. It fell 4.4% last week and 7.1% in September, so Monday’s close is a rebound, not yet a trend.
Country risk at 599 is just under the 600 mark that traders watch. Friday’s close was near 650, with press readings of 648 and 655. A return to that area would signal that the rebound is fading.
07 What to watch
- Brazil’s runoff, 25 October: A narrowing in the polls would hit Argentine assets as well.
- Industrial production for August, Wednesday 7 October, 19:00 UTC: Forecast −0.8% against −4.9% before (RT calendar).
- Country risk: Whether it stays below 600.
- September inflation: Polymarket traders price a monthly rate of 1.9% to 2.1% at 55%.
What Prediction Markets Say
Polymarket traders give Javier Milei a 2.1% chance of leaving office before 2027 (US$167,481 traded). For the September monthly inflation rate, Polymarket prices a reading of 1.9% to 2.1% at 55% and 1.6% to 1.8% at 27.5% (US$24,464 traded). Readings from 8:38 pm ET on 5 October.
