Today’s Focus
Argentina’s stock market fell on Monday 19 October as country risk, the extra yield investors demand to hold Argentine debt, jumped to 675 basis points. The Merval, the main stock index, lost between 1.4% and 1.8%, depending on the report.
Monday was also the first session of the Merval under MSCI’s administration. The index now holds 19 companies, with Cresud in and Telecom Argentina and Sociedad Comercial del Plata out.
The peso weakened 0.43% to 1,524 per US dollar in wholesale trading. Argentine shares listed in New York fell by up to 4.6%, led by the power company Edenor.
What matters today. Rising country risk and an index overhaul combined to push Argentine shares down on Monday.
01 The session in one read
Argentine shares fell on Monday as country risk rose to 675 basis points, its highest level of 2026, Cronista reported. The Merval lost about 1.4% by Cronista’s count, while another report put the fall at 1.8%.
The exact figure is unsettled, so we give a range. The direction is not in doubt, and several large shares fell by more than 2%.
The fall came on the Merval’s first day under MSCI’s administration. Cresud joined the 19-company index, and Telecom Argentina and Sociedad Comercial del Plata left.
Country risk at its 2026 high shows investors asking for more pay to hold Argentine debt, and shares fell with it. The index rule change makes day-to-day comparisons with earlier sessions hard. The variable to watch is whether country risk keeps rising after the new index settles in.
02 The day’s numbers
| Measure | Level | Change | Read |
|---|---|---|---|
| MSCI Merval (Cronista close) | 98,637 | −1.36% | Another report: −1.8%; first day under MSCI |
| Country risk | 675 bps | +27 bps | Highest level of 2026 |
| USD/ARS (wholesale) | 1,524 | +0.43% | Peso weaker |
| S&P 500 | 7,691 | +0.41% | US stocks rose but gave no lift |
| US 10-year yield | 5.139% | — | Higher US yields press emerging markets |
Country risk is a gauge that shows how much more yield investors want on Argentine dollar debt than on US Treasuries. At 675 basis points it was 27 points above the previous day.
The peso’s 0.43% fall took the wholesale rate to 1,524 per dollar. A weaker peso raises import costs and inflation pressure. Rio Times · Live Market Intelligence

03 Why it moved: country risk and the new index
The clearest driver was the jump in country risk. A rising reading signals that investors want more pay for the risk that Argentina could struggle with its debt.
The index change added noise. The Merval began its first day under MSCI’s administration, and the 19-company list shifted, which can force funds that track the index to trade.
Argentine depositary receipts in New York fell by up to 4.6%, with Edenor the worst. In Buenos Aires, Edenor fell 5.12% and BYMA 3.97%.
Argentina’s statistics office also reported a trade surplus of US$2.98 billion for September, Infobae reported. Exports were US$10.04 billion, up 23.5% from a year earlier, which brings dollars into the country.
04 The day’s movers
| Stock | Close (Buenos Aires) | Change | Note |
|---|---|---|---|
| Edenor (EDN) | ARS 1,575 | −5.12% | Power distributor; worst of the group |
| BYMA (BYMA) | ARS 242 | −3.97% | Exchange operator |
| YPF (YPFD) | ARS 8,235 | −2.31% | State-controlled oil company |
| Grupo Financiero Galicia (GGAL) | ARS 5,690 | −1.98% | Large private bank |
| Pampa Energía (PAMP) | ARS 5,165 | −1.43% | Energy group |
| Banco Macro (BMA) | ARS 10,270 | −0.68% | Bank |
Edenor, the power distributor, fell 5.12% in Buenos Aires, the worst of the large names. The exchange operator BYMA fell 3.97%.
YPF, the state-controlled oil company, slipped 2.31% and Grupo Financiero Galicia, one of the largest private banks, 1.98%. Banco Macro fell by less, 0.68%.
05 The regional scoreboard
| Index | Country | Change |
|---|---|---|
| MSCI Merval | Argentina | −1.36% |
| Ibovespa | Brazil | −0.17% |
| IPC | Mexico | +0.06% |
| IPSA | Chile | +0.02% |
| COLCAP | Colombia | −1.75% |
Argentina and Colombia were the weakest of the five major markets, with the COLCAP down 1.75% and the Merval down about 1.4% by Cronista’s count. Brazil’s Ibovespa slipped 0.17%.
Mexico’s IPC and Chile’s IPSA were essentially flat. The live market board above carries the latest closes.
06 The technical picture
The new Merval has no long history, so levels are hard to compare with last week. The direction of country risk is the cleaner signal this week.
The US 10-year Treasury yield at 5.139% adds pressure on emerging markets. Higher US yields make risky bets less attractive.
What Prediction Markets Say
Polymarket, a prediction market, priced Javier Milei at 48.0% and Axel Kicillof at 31.5% to win Argentina’s presidential election, with US$983,889 traded (read at 9:15 pm ET on 19 October). The same platform priced Milei leaving office before 2027 at 2.5%.
These prices are bets, not polls. They can move quickly on market and political news.
Why we show this: prediction markets turn real-money bets into a live probability that moves within minutes of the news, which is why investors, campaigns and newsrooms in the United States now follow them closely. We show them next to polls and official results, never instead of them.
07 What to watch
- Country risk: Whether it holds above 675 basis points; a further rise would raise funding costs.
- The new Merval: Watch fund flows as index trackers adjust to the 19-company list.
- The peso: The wholesale rate at 1,524 per dollar; further falls would add to inflation worries.
- Dollar inflows: September exports of US$10.04 billion, up 23.5%, support the supply of dollars.
